It is certain that Max () has chosen Yi,delta to be zero, and then the total must be minimal.

Ethernet communication between computers is too slow to develop faster communication between computers.Asynchronous SGDThe calculation method that was previously said to be synchronous requires waiting for each work core to be completed in order to summarize and calculate the results, so that part of the time is spent waiting.In view of this, an asynchronous SGD is proposedAssign tasks or assign them as usual, but who will upload the results to master and then update the data for each work core
with CNN, which is superior to the information extracted from the distorted sound.The second is to replace the normal DNN with the recurrent NN.Hmm-free RNN RecognitionThis translates the traditional sub-phone extraction into the collapsing function.The word output no longer takes the whole word as a unit, and the part of the word fragment as a unitFor a period of time when the gap between the voices is not pronounced, the "_" occupies the position.Using RNN is a lot lower than normal nn Error
description for the last few sentences. Conversely, you can do image retrieval.However, the resulting sentences are limited sentences, the computer can not "describe", so there is an improved version.First, use the CNN model to project the image into a vector, and then use LSTM to generate the sentence. This is a bit like a machine translation, just replaced the source language with an imageFinally, the evaluation method for this model (evaluation) is named mean rankWhen you create a picture fo

The Recurrent neural Network (NN) is the most commonly used neural network structure in NLP (Natural language Processing), and the convolution neural network is similar in the field of image recognition. Before we introduced CNN in detail in 4 blog posts, it is now necessary to introduce RNN before using CNN for a variety of purposes. Then it will be better to integrate practice.

The book of Deep Learning is also a great free book, but a little higher-learning.Once you have the basics, you can also develop in these areas:
Almost all of these deep learning materials are more or less related to computer vision (computer vision).
