  • Sagemaker model monitor and debugger are divine assistants to understand the “black box” of convolutional neural network

    Time:2021-10-26

    Many things can be better improved and enhanced only after understanding the internal principle and operation mechanism. However, some things are born “incomprehensible”, such as convolutional neural network (CNN). So how to further improve it? CNN has excellent practical performance in practical tasks such as image classification and target detection. Therefore, it has been introduced […]
