With the rapid development of the market economy, there are more and more projects in the financial industry, and their complexity and technical requirements are getting higher and higher. The development of computer technology has promoted the birth of robot consultants, and it is of great significance to use robot consultants to manage and supervise financial industry projects. In order to further analyze the development and supervision of robo-advisors under the digital inclusive financial system, this paper uses complex systems and clustering algorithms as technical support to carry out research. First, the traditional K-means algorithm is used to select the initial clustering center, to improve the noise and outlier processing capabilities, and to build a data mining system based on the improved algorithm. Then, a product design model for robo-advisors is built and the risks of robo-advisors are analyzed from three aspects: technology, market, and law. Analyzing the performance of the improved K-means algorithm, in the operation of the experimental dataset B, the accuracy of the clustering result after 6 iterations reached 97.08%, which shows that the algorithm has good performance. During the trial operation of the data mining system, the four types of customers of financial institutions were accurately clustered, and it was concluded that the main type of customers who brought benefits to financial institutions was high-income customers accounting for 10.75%. Robo-advisory product models are used to build five risk-level investment portfolios and conduct risk backtests. Except for the growth and income portfolio, other portfolios have consistently outperformed the performance benchmark during the analyzed time period. Running the research system of this paper in a financial institution, comparing the capital budget before and after the operation, found that the system can improve the accuracy of the budget and reduce the risk of the robo-advisor for the financial institution.
1. Introduction
1.1. Background Significance
In the operation of financial activities, there are many projects and tasks in parallel, which brings great impact to the traditional financial management concept. As an important application of financial technology in the field of wealth management, the mode of intelligent investment adviser is more complex. In the era of big data, there are many problems in the development and supervision of intelligent investment advisers [1]. Complex systems can be said to be all over every corner of daily life. Complexity science is an emerging research form that reveals the operation laws of complex systems [2]. The development and supervision of robo-advisors in the digital age is also an extremely complex research object. Therefore, it is a unique and meaningful new idea to study the development and supervision of digital inclusive finance and robo-advisors from the perspective of complex systems.
1.2. Related Work
Complex systems have become the focus of research in various fields due to their complexity and extensiveness. Lehuta et al. focused on handling uncertainties by optimizing model complexity for management goals and technical issues to increase confidence in complex system models. They reviewed how the complex system model fits into the existing institutional and legal environment of the current European fishery decision-making framework [3]. Although their research is of reference significance, their research methods lack innovation. Inclusive finance plays an important role in improving the income gap and improving the living standards of the poor and disadvantaged groups, so it is the object of key research. Yan et al. studied the impact of digital financial inclusion (DFI) on the stabilization of household consumption in China. They used the data from the two “Chinese Family Forum” studies from 2010 to 2016. They divided household income shocks into permanent and temporary parts and assessed whether digital financial inclusion can help families resist income shocks [4]. Their research data are very representative but lack certain accuracy in processing the data. The risk analysis of robo-advisors has always been the focus of attention in the financial field. Jung et al. determined the needs of robo-advisors, derived design principles, and evaluated it through algorithm iterations in a controlled laboratory study [5]. Their research has given us a deeper understanding of robo-advisors, but they have not made constructive suggestions for the improvement of its supervisory system.
1.3. Innovative Points in This Paper
In order to build a more complete robo-advisory supervision system, reduce risks, and improve the digital level of inclusive finance, this paper studies the development and supervision of robo-advisors based on complex systems and clustering algorithms. The innovations of this research are as follows. (1) Improve the traditional K-means algorithm, optimize the selection of its initial clustering center, reduce the influence of noise, and improve the processing ability of isolated points. (2) A data mining system is constructed based on the improved algorithm. The functions of the system include opening files, importing data, data preprocessing, data clustering, and result query. (3) This paper constructs the product design model of intelligent investment consultant and uses the model to construct five risk-level portfolios for risk backtesting. This paper analyzes the risks of intelligent investment advisers from three aspects of technology, market, and law and puts forward suggestions to improve the supervision of intelligent investment advisers.

2.1. Complex System
2.1.1. Characteristics of Complex Systems
Complex systems exist in every corner of human life. Ecosystem, population system, and global economic system belong to the category of the complex system. They all have the same characteristics as the complex system. Complex systems are systematic first, which is not the superposition of simple systems and organizations. Therefore, it is not possible to study complex systems with traditional system analysis methods [6, 7]. The elements of a complex system are in a nonlinear relationship. Simple partial stacking cannot represent the whole. The local laws are not the same as the overall laws. Therefore, a new system theory is needed to consider the logical relationship between complex systems.
Complex systems are also hierarchical and interactive. The hierarchical nature of the complex system is mainly embodied in the nested relationship of different levels of interconnectedness [8]. Therefore, in the research of complex systems, it is necessary to update the traditional concept of hierarchy and analyze the research objects from the level of complex system theory. Complex systems and the external environment always interact. Different complex systems together form a larger and more complex system. When studying a complex system, we must fully consider the internal environment and external environment, study the information exchange between them, and consider the self-adjustment of the complex system in the complex external environment.
Complex systems have emergence and development. Complex systems are composed of various subsystems and local subsystems which are composed of various combinations and correlations. If the format and functional structure of the subsystem and the local subsystem are different, the complex system will no longer be the sum of the subsystem functions [9]. Complex systems may have a variety of new features, so when studying complex systems, we must consider the original features and the various new features that may appear. The self-renewability of complex systems is mainly reflected in the continuous development of the system, which is also the fundamental reason for biological evolution and the development of human society. Complicated systems become intelligent due to internal hierarchical, systematic and external interactivity, and emergence, so they can adapt to the needs and changes of the environment.
2.1.2. Agent Complex System
The complex adaptive system is based on the characteristics of the complex system and further develops the Agent theory. Agent is an independent individual or subsystem in a complex system, with a life cycle, which can perceive and adapt to the environment, run autonomously in the environment, and even change the environment. The structure of Agent generally includes environment perception, reasoning, control decision-making, knowledge base, and communication [10].
Agent has the characteristics of autonomy, social ability, initiative, learning, and adaptability [11]. Agents can use their own state and knowledge to make decisions independently, without relying on outside help. Agents can achieve a certain degree of communication, negotiate and cooperate to resolve conflicts, and complete complex tasks. Agents can judge their own situation according to the external environment and actively make choices that are beneficial to themselves at the right time. Agents can also continue to learn, adjust their own state and behavior, and adapt to the constantly changing external environment.
A single Agent has autonomous capabilities to a certain extent, but a single Agent cannot complete work in a complex and changeable environment. A multiagent system emerged at the historic moment, in which each Agent can communicate with each other. There are two or more Agents in a multiagent system, each with autonomy but limited capabilities [12]. The multiagent system does not have complete global control. A single Agent has its own judgment and status. The calculation of the entire system is asynchronous, concurrent, or parallel. The coordination methods between Agents in the multiagent system are classified as follows.
As shown in Figure 1, the coordination methods of multiagent systems can be divided into two categories: explicit coordination and implicit coordination. The explicit coordination includes complete centralized coordination, complete distributed coordination, and centralized and distributed combined coordination, and implicit coordination includes social rules and filtering strategies.
