Definition of Knowledge Graph and its importance A knowledge graph is an information network constructed through nodes (entities) and edges (relationships), which is designed to represent a variety of information in a structured way, thus facilitating the understanding and processing of complex information by computers. In a knowledge graph, nodes usually represent different entities, such … Read more
Definition and basic principles of collaborative filtering Collaborative Filtering (CF) is a technique widely used in recommender systems where the main goal is to generate personalized recommendations by analyzing user behavior and preference data. The method relies on data about interactions between users and objects to find similarities and correlations that can help users discover … Read more
Basic concepts of sequence modeling Sequence modeling is a method of analyzing and processing sequence data with the aim of capturing its temporal or logical dependencies. In various domains, sequence data is presented as a time series, a text sequence, or any collection of data with a sequential order. The basic goal of sequence modeling … Read more
Basic Concepts of Self-Attention Self-attention is an advanced information processing mechanism widely used in machine learning and natural language processing. Simply put, self-attention enables a model to focus on the relevant parts of the data through weight allocation when processing the input data. This mechanism not only improves the efficiency of information processing, but also … Read more
