- Technical principles and concepts
2.1. Explanation of basic concepts
2.1.1. Distributed model
Distributed models refer to models trained on large-scale data sets, and their purpose is to work collaboratively on multiple computing nodes to complete model training and deployment. In the distributed model, each computing node is responsible for training a certain part of the model, and then splicing their respective training results together to finally complete the training of the entire model.
2.1.2. Parallel computing
Parallel computing refers to multiple computing nodes executing multiple tasks at the same time to improve computing efficiency. In distributed model training, parallel computing can help improve the training speed and efficiency of the model.
2.1.3. Model version control
