Introduction
I am PhD Scholar in School of Computing, University of Aberdeen UK. My Ph.D research is focused on learning mathematical models using Artificial Intelligence and Evolutionary Computing. My masters research was focused on medical imaging and data mining. I am experienced in applying machine learning and artificial intelligence models on medical data. If you are looking for further collaboration, I am happy to collaborate in AI, machine learning, Image processing and big data.

Inferring dynamic system models from observed time course data is very challenging compared to static system identification tasks. Dynamic system models are complicated to infer due to the underlying large search space and high computational cost for simulation and verification. In this research we aim to infer both the structure and parameters of...
Many real-world problems can be naturally formulated as discrete multi-objective optimization (DMOO) problems. In this research we propose a novel bio-inspired Physarum competition algorithm (PCA) to tackle DMOO problems by modelling the Physarum discrete motility over a hexagonal cellular automaton. Our algorithm is based on the chemo-attraction f...
Inferring models of dynamic systems from their time series data is a challenging task for optimization algorithms due to its potentially expensive computational cost and underlying large search space. In this study we aim to infer both the structure and parameters of a dynamic system model simultaneously by Particle Swarm Optimization (PSO), enhanc...
Application of Security monitoring for homes and offices is among the cutting edge for researchers. Efforts have been made in this regard by the software engineers to provide an efficient solution. With the advancement in the field of Internet of Things (IoT), there is an increasing demand of real time security for ones need. This research has focu...
Securing data is considered as one of our increasing demand in present time which is becoming a cutting edge for Researchers around the world. Process of securing data is still progressing but also gained a tremendous momentum. In this paper we facilitate Global Software Development in Cloud and present and compare various security challenges in Gl...

Hi,
I am new to research in the field of medicine. What would be the best way or method to find the prescribing cascade ? Should I have excel file and check it against the patient pharmacy record ?
I am trying to understand and use the best model selection method for my study. I have inferred models using swarm optimisation methods and used AIC for model selection. On the other hand I am also seeing a lot of references and discussions about BIC as well. Apparently, many papers have tried and concluded to use both AIC and BIC to select the best models. My question here is, What if I use ABC along side with AIC and BIC, how this will effect my study in better way and what would be its pros and corns of using ABC, BIC and AIC as model selection methods ?
Thanks
I carried out Kruskal Wallis H test in SPSS to do a pair wise comparison of three groups. I got some positive and negative values in Test statistics and Std. Test Statistics columns. I can conclude the results based on p-value but I don't know what the values indicates in Test Statistics and Std. Test Statics column and why some values are positive and why some are negative. Need some explanation please. Thanks in advance.
Hello everyone.
I have a query regarding PSO. I want to run PSO on survey to find out the customer response on different questions. In total I have 20 questions and its responses are in numeric format. What parameters should I consider in questions so that I can find an important or optimal question in all 20 questions of a survey !
Hi,
I am doing research on differential equations but came around the term dynamic system and dynamical system. Some papers says dynamic systems and some other says dynamical systems. I can't figure what the exact technical difference between these two terms or are they just two different words used with the same meaning. Thanks in Advance
Hi
I am trying to run python package pyabc(Approximate Bayesian Computation) for model selection between two list of values i.e My two models are Target=[2,3,4,5] and Observation=[3,4,2,5]. Observation model can be more than two. The main function of pyabc is ABCSMC which states that
Definition : ABCSMC(models: Union[List[Model], Model], parameter_priors:
Union[List[Distribution], Distribution, Callable], distance_function: Union[Distance,
Callable]=None, population_size: Union[PopulationStrategy, int]=100, summary_statistics:
Callable[[model_output], dict]=identity, model_prior: RV=None)
I don't know where to define and pass my two lists Target and Observation model. I have tried it several times but not able to do it. If there is any other method or code to solve my above mentioned problem using ABC then kindly refer it to me. Thanks
I am working on PSO dynamic functions . I want to
bring some changes in the formula of PSO so that instead of converging the particles to the Global Best(gb), it should repel the particles from the global best in the search space. If the global best changes its position in the search space then the particles in the search space should also changes its position and go far from the gb. Its more like opposite of PSO.
Months before i download few video tutorials of Data Mining tool WEKA by bill claster from sentimentmining.net/weka. The website is not working now. DO any one have idea about these tutorials or any good link of video tutorials from where i can learn WEKA and Rapid Miner.
Thankyou
I want to know about the new research ideas / directions in the field of software Archeology.. Can we name Reverse Engineering to Software Archeology .
