Abstract

The invention discloses a model training method, device and system, and belongs to the field of AI. The method comprises the following steps: receiving a machine learning model sent by first analysisequipment; and performing incremental training on the machine learning model based on a first training sample set, and feature data in the first training sample set being feature data of a local pointnetwork corresponding to the local point analysis device. The problem that the machine learning model obtained through offline training cannot effectively adapt to the requirements of local point analysis equipment is solved, and the method and the device are used for predicting the classification result.

Description

technical field [0001] The present application relates to the field of artificial intelligence (AI), in particular to a model training method, device and system. Background technique [0002] Machine learning refers to allowing the machine to train a machine learning model based on training samples, so that the machine learning model has the ability to predict the category of samples other than the training samples. [0003] At present, the data analysis system includes multiple analysis devices for data analysis. The multiple analysis devices may include cloud analysis devices and site analysis devices. The deployment method of the machine learning model in the system includes: the cloud analysis device performs model offline training, and then deploy the model after offline training directly on the site analysis device. [0004] However, the trained model may not be able to effectively adapt to the requirements of site analysis equipment. Contents of the invention [0...
