In Torch, recommender system modules are typically built as model classes using torch.nn.Module, commonly including modules such as:<\/p>\n

    \n
  1. Embedding layer: used to map discrete features of the input to dense vector representations, commonly used for representing features of users and items.<\/li>\n
  2. Neural network models, such as fully connected layers, convolutional layers, and recurrent neural networks, are used to learn the interactive relationships between users and items.<\/li>\n
  3. Loss function: A tool used to measure the difference between a model’s predicted results and the actual labels, commonly used loss functions include mean squared error (MSE) and cross-entropy loss.<\/li>\n
  4. Optimizer: Used to update model parameters, common optimizers include Stochastic Gradient Descent (SGD), Adam, etc.<\/li>\n
  5. Data processing module: used for loading and preprocessing data, including data loaders and data preprocessing functions.<\/li>\n<\/ol>\n

    These modules can be combined to build different types of recommendation system models, such as collaborative filtering-based recommendation systems, deep learning-based recommendation systems, etc. By combining and adjusting these modules, recommendation system models suitable for different scenarios and tasks can be constructed.<\/p>\n","protected":false},"excerpt":{"rendered":"
