Method and system for feature extraction and data prediction based on pre-training

A system for feature extraction and data prediction based on pre-training, comprising:

• a data unit configured to provide first data, second data and third data;
• a data process unit configured to process the first data, the second data and the third data to generate first processed data, second processed data and third processed data each having a predetermined format;
• and
• a feature extraction and data prediction unit, configured to build a first neural network, input the first processed data to the first neural network to perform a first training operation to generate a first trained neural network, input the second processed data to the first trained neural network and fixing a first portion of neurons of the first trained neural network to perform a second training operation to generate a second trained neural network, and input third processed data into the second trained neural network to generate a predicted result;
• wherein a first portion of neurons of the second trained neural network is the same as the first portion of neurons of the first trained neural network.
