Webbför 14 timmar sedan · Background: Blood is responsible for delivering nutrients to various organs, which store important health information about the human body. Therefore, the diagnosis of blood can indirectly help doctors judge a person’s physical state. Recently, researchers have applied deep learning (DL) to the automatic analysis of blood … WebbA key question that remains in the theory of deep learning is why such huge models (with many more parameters than data points) don't overfit on the datasets we use. Classical theory based on complexity measures does not explain the behaviour of practical neural networks. For instance estimates of VC dimension give vacuous generalisation bounds. WebbThe paper briefly reviews several recent results on hierarchical architectures for learning from examples, that may formally explain the conditions under which Deep Convolutional Neural Networks perform much better in function approximation problems than shallow, one-hidden layer architectures. t shirt printing silver spring md
