Problems solved by technology

[0002] At present, artificial intelligence is more and more widely used in production and life. Although the process of modeling (that is, building models) has been sampled after medium and long-term development, and there are multiple steps and processes that are enough for most users to understand, but The whole process is still very complicated, and the threshold of required professional knowledge is still very high. At the same time, automation solutions usually can only solve part of the problems, and the application of artificial intelligence in business is limited and the resources of professionals are limited, which also hinders the popularization and application of artificial intelligence. bring great resistance
[0003] The commonly used model building methods often need to provide the data features needed to build the model. First, the data features provided by the user may be messy, which will affect the training of the model. In addition, the feature extraction required for sample data The time is very long, and the number of sample data is often large, which makes it inefficient for users to determine data characteristics. Therefore, it is necessary to provide a data-based feature mining, automatic feature engineering, model selection and model tuning, etc., and then build a terminal end-to-end modeling mechanism
