Abstract

Embodiments of the invention provide a training method and device for a human face key point detection model. According to the method, for each training sample in a training sample set of the human face key point detection model, the human face key point detection model is adopted to carry out human face key point positioning on the training sample so as to obtain a prediction position of at least one human face key point in the training sample; for each human face key point, a position error between the predicted position and the real position of the human face key point is calculated, and a loss function value corresponding to the human face key point is determined according to the position error; and when the loss function value of the human face key point detection model is lower than a set threshold value, the human face key point detection model is determined to meet a training ending condition. Therefore, the performance of the trained human face key point detection model can be effectively improved.

Description

technical field [0001] The embodiments of the present application relate to the Internet field, and in particular, relate to a method and device for training a human face key point detection model. Background technique [0002] With the rapid development of artificial intelligence technology, neural network and machine learning models have been widely used in various fields, bringing convenience to people's life and work. For example, applying a machine learning model can efficiently identify the identity of the user corresponding to the face information, so as to complete operations such as payment or time attendance. [0003] In addition, face key point detection is a key step in many face applications. As a basic module, it is widely used in face attribute analysis such as face alignment, face recognition, 3D face reconstruction, and expression analysis. [0004] In recent years, compared with traditional methods, face key point detection methods based on deep learning h...
