Embodiment Construction

[0035] The method and apparatus in the present application embodiment can be applied to a scene that recognizes the gesture of the rodents based on the image sequence. The image sequence can be a plurality of image frames in the video. Multiple image frames can be a plurality of image frames in a video. The image sequence can also be multiple images of animals collected by image acquisition devices such as cameras. The rodent can be, for example, a mouse or the like.

[0036] In order to facilitate the understanding of the present application embodiment, the background of the present application will be described in detail.

[0037]The behavior of biological neurons is related to the activity of animals, and the attitude variation of animals typically causing corresponding changes in neurons. Therefore, the exploration of the connection and interactive mode of complex network composed of neurons under specific behavior is very important in the field of neuroscience and medical. Th...

Abstract

The invention provides a training method and a training device. The method comprises the following steps: acquiring a training sample, wherein the training sample is an image sequence for recording rodent movement; inputting the training sample into a neural network model to obtain a recognition result of the posture of the rodent, the recognition result comprising key points in the posture of the rodent; and training the neural network model by using a gradient descent method by using a loss function according to the recognition result of the posture of the rodent. Wherein the loss function comprises a time constraint term, and the time constraint term is used for constraining the position of a key point in the posture of the rodent between adjacent image frames in the image sequence. When the neural network model trained according to the method is used for posture recognition of rodents such as mice, the jitter phenomenon of the recognition result in the time domain can be effectively avoided.

Description

Technical field [0001] The present application relates to the field of artificial intelligence, and therefore specifically involves a training method and a training device. Background technique [0002] The gesture recognition refers to identifying and / or extracting and / or extracting the action and / or key points of the organisms in the image or video using the neural network model. [0003] In the prior art, when the key point in the image sequence of the rodent motion is performed, the key points in a single image or a single image frame are typically extracted, and the key points may be, for example, the joints of a rodent. . The identification result obtained in this way is prone to jitter, so that the motion trajectory of the key point is not smooth enough. Inventive content [0004] In view of this, the present application example provides a training method and a training device to improve the accuracy and identification efficiency of the neural network model in perfo...
