he Artificial Intelligence (AI) began in the mid-
20th century when scientists first imagined
machines that could simulate human intelligence
[1]. Over the decades, AI has progressed from basic
algorithms to more complex models. Currently, AI can
simulate and surpass human capabilities in specific tasks.
In the digital era, AI stands as a transformative force in
various global industries, as shown in Fig. 1.
In healthcare, technology has evolved in diagnostic
procedures with AI tools that can detect diseases with
accurate results [2]. In finance, there is no more manual
fraud detection. Instead, sophisticated algorithms
examine millions of transactions in real-time, flagging
suspicious activity with high accuracy [3]. Traditionally
driven by intuition and human experience, the retail
sector relies on AI models to tailor personalized shopping
experiences and transform business interactions [4].
Farmers are leveraging AI-based predictive analytics to
make informed decisions about growing, harvesting, and
irrigating crops in the agricultural domain, bridging the
gap between traditional practices and technological
innovation [5]. AI has also been used in the energy and
automotive sectors, facilitating monitoring and
automation. Table 1 summarizes the main AI applications
in the industry.
Although it looks promising, the road to integrating
AI is not smooth. The industry is grappling with challenges
such as ensuring data privacy, navigating the complexities
of potential biases in AI models, and coping with the
growing demand for a skilled workforce proficient in these
new technologies [6]. Furthermore, the rapid proliferation
of AI applications underscores the need for systematic
documentation and understanding of real-world
implementation. This review seeks for an in-depth
exploration of the practical implementation, challenges,
and successes associated with AI in various sectors. Thus,
this paper can provide a broader perspective to guide
professionals, researchers, and stakeholders in AI
technology.

HEALTHCARE
The integration of AI in healthcare has resulted in
expedited diagnosis, personalized care, and predictive
analytics. In particular, medical imaging has witnessed a
revolutionary shift due to AI capabilities in image
recognition and interpretation.
Early Detection of Adolescent Idiopathic
Scoliosis
AI and deep learning based on convolutional neural
networks (CNN) have been used to help doctors analyze
scoliosis patients [7]. The CNN architecture was proposed
to detect the location of spinal vertebrae from X-ray
images to evaluate the Cobb angle automatically. The
proposed method can measure Cobb angles with up to
93.6% accuracy and has excellent reliability compared to
manual clinician measurements, making it usable in real-
world clinical settings. The method also reduces
diagnostic time, leading to faster interventions to treat
patients better. Successful integration may encourage
other healthcare institutions to explore similar AI-based
diagnostic solutions.
Diagnosis of Breast Cancer on Mammograms
Breast cancer is a significant health problem for
women globally. Early detection is essential for effective
prevention and treatment. A traditional mammogram, an
X-ray image of the breast, helps spot the early signs of this
cancer. AI can be applied to segmenting areas detected as
cancer on mammograms [8]. AI can also help improve
image quality and find anomalous patterns. AI is changing
the way breast cancer is detected, making the process
faster and often more precise. However, AI in medicine
can be a tool, not a substitute for human expertise. A
doctor and radiologist can do it for further detection and
decision-making.
Drug Discovery and Development
Drug discovery and development is a long and
expensive process. With AI, this process gets a significant
boost. AI algorithms analyze extensive data sets to
identify potential drug candidates by predicting how
different compounds might interact with biological
pathways [9]. So, instead of the traditional trial and error
method, researchers can now start by focusing only on the
most promising compounds. In addition, AI can help
predict potential side effects, making the drug
development process safer. AI streamlines and optimizes
the journey from the lab to the pharmacy shelf,
potentially getting effective drugs to patients faster and
more affordably.
Natural Language Processing (NLP) for
Medical Records
Medical records often contain large amounts of
unstructured text, ranging from doctor's notes to patient
histories. NLP, a branch of AI, is designed to understand,
interpret, and extract meaningful information from such
texts. In the context of medical records, NLP algorithms
sift through data, identifying important details such as
diagnosis, treatment, and patient outcomes [10]. NLP
helps in efficient patient management and research,
which provides information for medical studies and
strategies. NLP transforms seas of text in medical records
into actionable information, improving patient care and
healthcare research.
FINANCE
AI has played a critical role in tackling complex challenges
in finance, such as fraud detection and risk assessment.
The high volume of financial transactions every day makes
manual fraud detection nearly impossible. Financial
institutions face a constant battle against ever-evolving
fraud techniques. Traditional systems are often reactive,
identifying fraud after it has occurred. Financial entities
can proactively detect and deter suspicious activity with
AI predictive analytics.
Fraud Detection in Real-Time Payment
Systems
In a real-time payment system, fraud detection
must be instantaneous. Traditional approaches often fail
to keep up with this speed and transaction volume. AI
methods, such as deep learning, are trained on millions of
transactions [3]. These models can detect patterns and
anomalies faster than humans. The AI model can mark
high-value transactions from countries where users have
never transacted as suspicious. Several financial
institutions that integrated AI-based real-time fraud
detection observed a reduction in fraudulent transactions
of up to 40% while also reducing false positives.

Predicting Credit Card Default Risks
Credit card companies must predict the probability
of a default user to decide on credit limits and reduce
losses. By training historical data, including past
transactions, payment histories, and social factors, AI
models can provide more accurate predictions about the
likelihood of users defaulting [11]. More advanced models
even consider non-traditional data, such as social media
activity. Credit card companies using AI-based risk
assessment tools can reduce bad loans compared to
traditional methods.
Automated Trading and Risk Management
The stock market is notoriously unpredictable.
Manual trading strategies cannot always keep up with
rapid fluctuations. AI algorithms, trained on large datasets
of years of market data, can make real-time trading
decisions [12]. By analyzing patterns, AI can predict short-
term price changes with greater accuracy. In addition, AI
assists portfolio managers in risk assessment by
forecasting potential market downturns based on global
news and events. Trading companies using AI-based
trading strategies consistently outperform traditional
methods, some reporting an increase in annual returns of
up to 15%.
RETAIL
Physical and digital retailers have turned to AI to enhance
the customer shopping experience, offering personalized
product recommendations based on individual
preferences and browsing history. Modern consumers
expect a personalized shopping experience.
Real-Time Personalized Online Shopping
Experience
Online shoppers often face many choices, leading to
potential shopping cart abandonment. The AI model is
trained on users' browsing patterns, purchase history, and
click-through rates, dynamically adjusting the online
shopping interface [4]. This personalization can range
from visual layout adjustments to specific product
highlights. E-commerce platforms that have integrated AI
personalization tools have reported a 20% increase in
conversion rates and a 15% increase in average order
value.
In-Store Personalized Recommendations
through Augmented Reality (AR)
Brick-and-mortar stores aim to replicate a
personalized online experience for in-store customers.
Augmented Reality (AR) devices, powered by AI
algorithms, analyze a customer's purchase history and
store interactions [13]. The AR device then overlays real-
time product information and recommendations onto the
customer's view. Stores using AR and AI for personalized
recommendations have increased in-store sales by 10-
15% and increased customer return rates by 20%.
Virtual Try-Ons and Personalized Styling
Suggestions
The challenge of choosing the right size and style is
familiar to both online and in-store shoppers. With AI and
AR, virtual test tools allow customers to wear clothes,
accessories, or make-up virtually [13]. AI suggests sizes,
colors, and complementary products based on virtual
experiences and past purchases. Retailers offering virtual
trials and AI-driven style advice saw a 20-40% decrease in
product returns and a 3% increase in sales of
complementary products.
AGRICULTURE
Modern agriculture seeks to combine traditional wisdom
with technological advances. AI has emerged as a vital
tool, providing farmers with data-driven insights that
were previously inaccessible. Predictive analytics with AI
offers solutions to optimize crop yield predictions based
on various parameters.
Predicting Yield Based on Weather Patterns
Weather fluctuations have a direct impact on crop
yields. Traditional predictive models often lack real-time
response to sudden weather changes. Machine learning
models, which are trained on historical weather data, crop
yields, and satellite imagery, can predict crop yields based
on predicted weather patterns [5]. Farms using AI models
report yield increases of up to 20% due to timely
interventions, optimizing irrigation, and predictive pest
control.

Soil Health Analysis and Crop Yield
Soil health, including nutrient content and moisture
levels, is a major factor in crop yields. Sophisticated
sensors and AI algorithms can analyze soil samples,
predicting which plants grow best in certain soil types and
conditions [5]. These predictions can also be extended to
specific fertilizer or treatment recommendations. By
aligning crop planting with soil health recommendations,
the farm recorded a 15% increase in crop yields and a 10%
reduction in fertilizer and maintenance costs.
Drone-based Crop Surveillance and Yield
Prediction
Regular crop monitoring can detect early signs of
disease or pest infestation that can affect yields. Drones
equipped with AI-based cameras can capture high-
resolution images of plants [14]. Then, deep learning
models analyze the images to detect abnormalities,
predict the potential impact of outcomes, and suggest
interventions. Early detection and intervention can
reduce crop losses, ensuring more consistent and higher
yields.
ENERGY
The energy sector is currently undergoing a
transformative AI-driven evolution. As global energy
demand increases and the urgent need for sustainable
solutions increases, AI delivers innovation, promising
efficiency, adaptability, and foresight in diverse energy
production, distribution, and consumption fields.
Renewable Energy Forecasting
Renewable energy sources, such as wind and solar,
are affected by unpredictable natural factors. AI is used
to improve energy production forecasting from these
sources [15]. AI models can more accurately predict
energy output by analyzing large amounts of data,
including weather patterns, historical energy production,
and satellite imagery. Thus, the energy network can
effectively integrate renewable sources, optimize energy
distribution, and reduce dependence on non-renewable
reserves. AI-powered forecasting helps maximize the
efficiency and reliability of renewable energy, making it a
more viable alternative to traditional energy sources.
Energy Efficiency in Buildings
Buildings, such as homes and office spaces, consume
much energy. AI plays an essential role in increasing the
energy efficiency of these structures. AI algorithms can
optimize heating, cooling, and lighting systems in real-
time by analyzing data from sensors, past energy usage,
weather forecasts and occupancy patterns [16]. AI can
ensure that energy is only used when and where needed
to prevent wastage. Additionally, AI can predict when a
system may need maintenance, avoiding energy
inefficiencies due to wear and tear. Therefore, AI is an
intelligent manager for building systems, ensuring optimal
energy consumption and significantly reducing costs.
Predictive Maintenance in Energy
Infrastructure
Energy infrastructure, such as power plants, turbines,
and transmission lines, are important assets that require
regular maintenance. Traditional maintenance strategies
often rely on scheduled inspections or waiting for
equipment to fail. The predictive maintenance approach
can be applied with AI. AI can analyze data from sensors
placed on equipment, identifying patterns and anomalies
that hint at potential failure or wear and tear [17].
Foreseeing these problems before they cause damage,
operations can continue without interruption, and costly
emergency repairs can be avoided. AI ensures energy
infrastructure stays in peak condition, reduces downtime,
and maximizes efficiency.
AUTOMOTIVE
The automotive field is undergoing a radical
metamorphosis powered by AI. As ancient vehicle
mechanics are entwined with digital AI prowess, the
horizon of automotive possibilities is expanding, ushering
in an era of enhanced safety, unprecedented efficiency
and reimagined driving experiences.
Autonomous Vehicles
Autonomous vehicles, often referred to as self-driving
cars, rely heavily on AI to navigate and make decisions.
Using a variety of sensors, cameras and radar, the vehicle
is constantly gathering data about its environment. AI
processes this data in real-time, helping vehicles

recognize obstacles, read traffic signs, and understand
road conditions [18]. Additionally, AI algorithms can
predict the actions of pedestrians and other vehicles to
make driving decisions, such as when to brake or change
lanes. AI, such as deep learning, enables these vehicles to
learn from large amounts of driving data and continuously
improve their performance. Thus, AI functions as the brain
of autonomous vehicles, allowing them to navigate
complex urban environments safely and efficiently.
Predictive Maintenance
The automotive industry has applied AI to predict
and prevent vehicle breakdowns before they occur. The
vehicle continuously delivers performance data by
integrating on-board sensors and diagnostics. AI
algorithms analyze this data, detecting subtle patterns
and irregularities that might indicate potential damage or
wear on some parts [19]. Instead of following a fixed
service schedule or waiting for a breakdown, car owners
are forewarned about which components need attention.
This predictive approach increases vehicle life, ensures
safer driving conditions, and can reduce unforeseen repair
costs. AI turns vehicles into self-diagnosis systems,
offering timely maintenance insights to keep them
running optimally.
Intelligent Voice Assistants
Modern vehicles are equipped with AI voice
assistants that go beyond basic speech recognition. AI can
understand context, preferences and even adapt to
individual user voices. Drivers can use voice commands to
control navigation, play music, send messages, or get real-
time updates on vehicle performance, all without taking
their hands off the wheel. AI processes these commands
quickly and accurately, ensuring smooth interactions [20].
Over time, these assistants learn from user behavior and
can proactively provide suggestions, such as finding a gas
station on a long trip or suggesting a faster route. This AI-

Essential for decision-making, measurement is a cornerstone of various fields including energy management. While direct methods exist for some quantities like length, most physico-chemical properties require indirect assessment based on observable effects. Historically, pressure was measured by the water column height, and temperature by mercury expansion. Recent advancements in artificial intelligence (AI) offer a transformative approach by combining vast datasets with traditional measurements. This holds immense potential for applications facing extreme conditions and involving complex fluids where measurement is extremely challenging (over 1500 K and 5 MPa). In this study, an AI model is evaluated to replace online rheometers (293–1173 K, 0.15–3.5 MPa). A machine learning model utilizes a neural network with up to 8000 neurons, eight hidden layers, and over 448 million parameters. Trained, tested, and validated on three experimental databases with over 600 test conditions, the New Generation Predicted Viscosity Sensor (NGPV sensor) achieves exceptional accuracy (less than 4.8 × 10−7 Pa·s). This virtualized sensor proves highly relevant for hypersonic airbreathing applications involving fuel degradation and energy conversion. It maintains excellent predictability (accuracy below 6 × 10−6 Pa·s) even at flow rates 10 times higher than calibration, surpassing traditional rheometers limited by calibration needs and a lower viscosity measurement threshold (10−4 Pa·s).

Background Decision-making in the stock market is convoluted as it requires significant trading experience and knowledge. Faced with a huge range of stocks, investors in the stock market may be overwhelmed and daunted by the number of choices available on their plates. Financial institutions also face the problem of recommending stocks that cater to the investors’ trading strategies. Objective In this paper, we develop and explore three different approaches that can be used to build a stock recommender system that takes into account the investors’ needs and interests. Furthermore, to ensure the profitability of the recommended portfolios and to support the investors in making risk-informed decisions, we evaluate their Expected Returns and Value-at-Risks. Methods & Findings Hierarchical clustering was performed to better understand groups of traders that are similar in their needs and preferences and thus computational efficiency was improved. Three stock recommender systems, the K-Nearest Neighbour (kNN), Singular Value Decomposition (SVD) and Association Rule Mining (ARM) was explored and evaluated. Our short term, medium term and long term portfolios average rate of return was 4.15%, 10.24% and 23.17% respectively. Conclusion Our study demonstrates promising recommendation results that not only catered to the user's profile but also contributed to the portfolio profitabilities with minimal financial loss. Stock recommendations were beneficial to users when their preferences were considered.

Financial fraud, considered as deceptive tactics for gaining financial benefits, has recently become a widespread menace in companies and organizations. Conventional techniques such as manual verifications and inspections are imprecise, costly, and time consuming for identifying such fraudulent activities. With the advent of artificial intelligence, machine-learning-based approaches can be used intelligently to detect fraudulent transactions by analyzing a large number of financial data. Therefore, this paper attempts to present a systematic literature review (SLR) that systematically reviews and synthesizes the existing literature on machine learning (ML)-based fraud detection. Particularly, the review employed the Kitchenham approach, which uses well-defined protocols to extract and synthesize the relevant articles; it then report the obtained results. Based on the specified search strategies from popular electronic database libraries, several studies have been gathered. After inclusion/exclusion criteria, 93 articles were chosen, synthesized, and analyzed. The review summarizes popular ML techniques used for fraud detection, the most popular fraud type, and evaluation metrics. The reviewed articles showed that support vector machine (SVM) and artificial neural network (ANN) are popular ML algorithms used for fraud detection, and credit card fraud is the most popular fraud type addressed using ML techniques. The paper finally presents main issues, gaps, and limitations in financial fraud detection areas and suggests possible areas for future research.

Purpose The transition to omnichannel retail is the recognized future of retail, which uses digital technologies (e.g. augmented reality shopping assistants) to enhance the customer shopping experience. However, retailers struggle with the implementation of such technologies in brick-and-mortar stores. Against this background, the present study investigates the impact of a smartphone-based augmented reality shopping assistant application, which uses personalized recommendations and explainable artificial intelligence features on customer shopping experiences. Design/methodology/approach The authors follow a design science research approach to develop a shopping assistant application artifact, evaluated by means of an online experiment ( n = 252), providing both qualitative and quantitative data. Findings Results indicate a positive impact of the augmented reality shopping assistant application on customers' perception of brick-and-mortar shopping experiences. Based on the empirical insights this study also identifies possible improvements of the artifact. Research limitations/implications This study's assessment is limited to an online evaluation approach. Therefore, future studies should test actual usage of the technology in brick-and-mortar stores. Contrary to the suggestions of established theories (i.e. technology acceptance model, uses and gratification theory), this study shows that an increase of shopping experience does not always convert into an increase in the intention to purchase or to visit a brick-and-mortar store. Additionally, this study provides novel design principles and ideas for crafting augmented reality shopping assistant applications that can be used by future researchers to create advanced versions of such applications. Practical implications This paper demonstrates that a shopping assistant artifact provides a good opportunity to enhance users' shopping experience on their path-to-purchase, as it can support customers by providing rich information (e.g. explainable recommendations) for decision-making along the customer shopping journey. Originality/value This paper shows that smartphone-based augmented reality shopping assistant applications have the potential to increase the competitive power of brick-and-mortar retailers.

The Cobb angle measurement of the scoliotic spine is prone to inter- and intra-observer variations in the clinical setting. This paper proposes a deep learning architecture for detecting spine vertebrae from X-ray images to evaluate the Cobb angle automatically. The public AASCE MICCAI 2019 anterior-posterior X-ray image dataset and local images were used to train and test the proposed convolutional neural network architecture. Sixty-eight landmark features of the spine were detected from the input image to obtain seventeen vertebrae on the spine. The vertebrae locations obtained were processed to automatically measure the Cobb angle. The proposed method can measure the Cobb angle with accuracies up to 93.6% and has excellent reliability compared to clinicians’ measurement (intraclass correlation coefficient > 0.95). The proposed deep learning architecture may be used as a tool to augment Cobb angle measurement in X-ray images of patients with adolescent idiopathic scoliosis in a real-world clinical setting.

The credit card business has become an indispensable financial service for commercial banks. With the development of credit card business, commercial banks have achieved outstanding results in maintaining existing customers, tapping potential customers, and market share. During credit card operations, massive amounts of data in multiple dimensions—including basic customer information; billing, installment, and repayment information; transaction flows; and overdue records—are generated. Compared with preloan and postloan links, user default prediction of the on-loan link has a huge scale of data, which makes it difficult to identify signs of risk. With the recent growing maturity and practicality of technologies such as big data analysis and artificial intelligence, it has become possible to further mine and analyze massive amounts of transaction data. This study mined and analyzed the transaction flow data that best reflected customer behavior. XGBoost, which is widely used in financial classification models, and Long-Short Term Memory (LSTM), which is widely used in time-series information, were selected for comparative research. The accuracy of the XGBoost model depends on the degree of expertise in feature extraction, while the LSTM algorithm can achieve higher accuracy without feature extraction. The resulting XGBoost-LSTM model showed good classification performance in default prediction. The results of this study can provide a reference for the application of deep learning algorithms in the field of finance.

Unmanned Aerial Vehicles (UAVs) combined with machine learning have a great potential for crop yield estimation. In this study, a UAV equipped with an RGB (Red, Green, Blue) camera and computer vision algorithms were used to estimate coffee tree height and crown diameter, and for the prediction of coffee yield. Data were collected for 144 trees between June 2017 and May 2018, in the Minas Gerais, Brazil. Six parameters (leaf area index-LAI, tree height, crown diameter, and the individual RGB band values) were used to develop UAV-based yield prediction models. First, a feature ranking was performed to identify the most significant parameter(s) and month(s) for data collection and yield prediction. Based on the feature rankings, the LAI and the crown diameter were determined as the most important parameters. Five algorithms were used to develop yield prediction models: (i) linear support vector machines (SVM), (ii) gradient boosting regression (GBR), (iii) random forest regression (RFR), (iv) partial least square regression (PLSR), and (v) neuroevolution of augmenting topologies (NEAT). The mean absolute percentage error (MAPE) was used to evaluate the yield prediction models. The best result was obtained by the NEAT algorithm (MAPE of 31.75%) for a reduced dataset containing only the most important features (LAI and the crown diameter) and the most important months (December 2017 and April 2018). The results suggest that a dataset of the most important month (December) could be used for the yield prediction model, reducing the need for extensive data collection (e.g., monthly data collection).
