The following statements about BP network are correct ()
A. BP network is a feedback network
B. Traditional BP networks generally use secondary networks.
C. The basic BP algorithm includes two processes of signal forward propagation and error back propagation
D. The three core parts of the BP neural network learning algorithm are weight adjustment, output layer connection weight adjustment, and hidden layer connection weight adjustment.
Among the following statements about machine learning, the correct one is()
According to different learning theories, machine learning models can be divided into supervised learning, semi-supervised learning, unsupervised learning, and reinforcement learning.
B. In practical applications, machine learning is mainly based on unsupervised learning or semi-supervised learning.
C. The supervision of supervised learning is reflected in the fact that all the data to be processed by the machine must be manually defined the corresponding category, and then the classification algorithm is trained, and finally the usable classifier is obtained.
D. Supervised learning data sets are labeled, unsupervised compared to supervised, there is no training process, but directly use the data for modeling and analysis
