AI modeling and training practice based on HF transformers

We often use scikit-learn to model data for both supervised and unsupervised learning tasks. We are familiar with object-oriented design, such as starting a class and calling subfunctions from the class. However, when I personally use PyTorch, I find design patterns that are similar but not the same as scikit-learn. Recommended online tools: Three.js AI […]

elasticsearch data modeling

Data modeling Nesting type: Nested Nested is a type of object and is an indexing operation for complex type object arrays in Elasticsearch. Elasticsearch has no concept of internal objects. Therefore, when ES stores complex types, it will flatten the complex hierarchical results of the object into a list of key-value pairs. For example: PUT […]
