    Investigation and designing a comprehensive supply chain database for Walmart

    In light of the rapid progression of digital technology, fierce competition, and the ever-shifting demands of consumers, the contemporary retail sector is continually evolving. This underscores the critical need to embrace digital solutions. This study seeks to aid Walmart, one of the world's largest retailers, in improving supply chain efficiency, optimizing inventory management, and enhancing the overall customer experience by creating a comprehensive supply chain database. Specifically, we employ the core entity method to identify Walmart's key entity, which is the "product," and ascertain its associated entities. Subsequently, we establish relational models based on the attributes and relationships of each table, considering real-world scenarios, such as one-to-many and many-to-many relationships. We employ normalization techniques to ensure the proper utilization of functional dependencies and candidate keys for each entity. This guarantees that the designed tables adhere to the principles of the First, Second, and Third Normal Forms, preserving data integrity while minimizing redundancy. Furthermore, we create a set of logical database commands, illustrated through flowcharts, and rigorously test their functionality and efficiency. Lastly, we explore potential directions for future research. The successful implementation of this design relies on robust data management practices and a reliable database system tailored to meet Walmart's specific needs. This results in a logically structured and standardized supply chain database. The research findings underscore the vital importance of a well-conceived supply chain database in addressing the challenges faced by large-scale retail operations like Walmart supermarkets.

    Traffic light control with reinforcement learning

    Urban traffic signal optimization is important for alleviating congestion in urban transportation systems. This study proposes a real-time traffic light control algorithm based on deep Q learning with a reward function that accounts for queue lengths, delays, travel times, and throughput. The model dynamically decides phase changes based on current traffic conditions. The training of the deep Q network involves an offline stage from pre-generated data with fixed signal timing and an online stage using real-time traffic data. A deep Q network structure with a“phase gate component is used to simplify the model's learning task under different phases. A“memory palace" mechanism is used to address sample imbalance during the training process. Both synthetic and real-world traffic flow data are used to validate our approach under an urban road intersection scenario in Hangzhou, China. Results demonstrate significant performance improvements of the proposed method in reducing vehicle waiting time (57.1% to 100%), queue lengths (40.9% to 100%), and total travel time (16.8% to 68.0%) compared to traditional fixed signal timing plans.

    Should machine learning be applied in credit risk accessment

    In the past, analysts evaluated whether to offer loans to particular applicants using rule-based approaches. However, due to the sudden rise in applicants and a labor shortage, financial institutions have created quantitative methods of decision-making. Credit scoring models are constructed. In this essay, random forest model, support vector machine regression model and Probit model are performed and compared according to the dataset from a major U.S. credit cards company. The result demonstrates that while machine learning techniques can improve the efficiency and accuracy of credit risk assessment, it does face some problems and limitations. Random forest model is capable of handling high-dimensional data and is not complicated to run. However, database with fewer features or samples will have lower classification accuracy. Support vector machine regression model has high accuracy and prevents overfitting to some degree. It is sensitive to the choice of kernel parameters and regularization term. By testing how important Mill Ratio is, the Probit model produces more accurate results. However, the model is more complex than the other two. In future research, we propose to enhance and extend our work by using more artificial intelligence algorithms and evaluation metrics.

    Breast cancer classification based on hybrid machine learning model

    This study proposes a hybrid model that combines K-Means clustering and Random Forest classification as an approach for breast cancer classification. The objective is to exploit the advantages of unsupervised clustering and supervised classification techniques to enhance the accuracy and robustness of classification models. The dataset underwent preprocessing procedures encompassing the handling of missing values, feature normalization, and feature selection. Missing values were addressed through appropriate methods, and features were scaled and selected based on variance threshold or correlation analysis. Subsequently, K-Means clustering was applied to the preprocessed data to assign cluster labels to each sample. The study then proceeded to train a Random Forest classifier by incorporating both the cluster labels and the raw gene eigenvalues as mixed features. This integration of gene expression values and cluster labels provides supplementary information to the classifier, enabling the capture of more intricate patterns within the data. The Random Forest classifier was trained using optimized parameters determined through parameter tuning, including the number of trees, maximum depth, and minimum number of split samples. Extensive experiments and evaluations conducted in this study revealed that the hybrid model outperformed the standalone Random Forest classification. The incorporation of K-Means clustering facilitated the discovery of underlying data structures and patterns, ultimately enhancing the classifier's discriminatory ability. The hybrid model exhibited superior accuracy, precision, recall, and F1 scores, demonstrating its efficacy in accurately classifying breast cancer samples.

    Model-based reinforcement learning for service mesh fault resiliency in a web application-level

    Microservice-based architectures enable different aspects of applications to be created and updated independently, even after deployment. Associated technologies such as service mesh provide fault resiliency through attribute configurations that govern self-adaptive application-level behavior in response to failures, in a manner transparent to the application and constituent microservices. While this provides tremendous flexibility, the configured values of these attributes – and the relationships among them – can significantly affect the performance and fault resilience of the overall application. It is thus important to perform fault injection and load testing on the application, prior to full deployment. However, given a large number of possible attribute combinations and the complexities of the distributed system underlying microservices and service mesh architectures, it is virtually impossible to determine through traditional software development practices the worst combinations of attribute values and load settings with respect to self-adaptive application-level fault resiliency. To this end, we present a model-based reinforcement learning approach that determines the combinations of attribute and load settings that result in the most significant fault resilience behaviors at an application level. We validate our approach through a case study on a simple “request-response” service using the Istio service mesh. Our analysis shows that, even for a simple service, our model-based reinforcement learning approach outperforms a baseline selection of action parameters. Further, we show that communicative multi-agent reinforcement learning improves the performance of both the non-communicative single and multi-agent learning paradigms.
