Building your recurrent neural network-step by step
Welcome to Course 5 ' s-A-assignment! In this assignment, you'll implement your The recurrent neural network in NumPy.
Recurrent neural Networks (RNN) are very effective for Natural Language processing and other sequence tasks because they h Ave "Memory". They can re
, the objective function of SVM is still convex. Not specifically expanded in this chapter, the seventh chapter is detailed.Another option is to fix the number of base functions in advance, but allow them to adjust their parameters during the training process, which means that the base function can be adjusted. In the field of pattern recognition, the most typical algorithm for this method is the forward neural network (Feed-forward
Now that the "neural network" and "Deep neural network" are mentioned, there is no difference between the two, the neural network can not be "deep"? Our usual logistic regression can be thought of as a neural network with sigmoid (logistic) for output layer activation functions without hidden layers, and it is clear th

in the first convolutional layer and the first fully connected layer. Finally, they reduced the number of first convolutional neurons from 20 to 10, reducing the number of neurons in the first fully-connected layer from 500 to 100. After 2000 iterations, the network accuracy rate reached 98.2%.Figure 9 Mnist network analysis diagram. From left to right, the first convolution layer, the second convolutional layer, the first fully connected layer, and the second fully connected layer.In general,
convolutional neural Network (CNN) is the foundation of deep learning. The traditional fully-connected neural network (fully connected networks) takes numerical values as input.If you want to work with image-related information, you should also extract the features from the image and sample them. CNN combines features, down-sampling and traditional
programming principle and construct a dynamic sequence model. This requires recurrent neural Network (RNN) to achieve.RNN is usually translated into cyclic neural networks, and its similar dynamic programming principles can also be translated into sequential recurrent neural networks.Of course there are structural rec

Just entered the lab and was called to see CNN. Read some of the predecessors of the blog and paper, learned a lot of things, but I think some blog there are some errors, I try to correct here, but also added their own thinking and deduction. After all, the theory of CNN has been put forward, I just want to be able to objectively describe it. If you feel that there is something wrong with this article, be sure to tell me in the comments below.convolutional n

Cyclic neural networks (recurrent neural networks,rnns) have been successful and widely used in many natural language processing (Natural Language processing, NLP). However, there are few learning materials related

Deep Learning SpecializationWunda recently launched a series of courses on deep learning in Coursera with Deeplearning.ai, which is more practical compared to the previous machine learning course. The operating language also has MATLAB changed to Python to be more fit to the current trend. A study note on this series of courses will be made here.The deep learning specialization is divided into five courses, namely:
called the output layer. For example, a superscript (2) Subscript 1 represents the first excitation of the 2nd layer, that is, the first excitation of the hidden layer. The so-called excitation (activation) refers to a specific neuron after reading the information, need to use the parameter matrix, after a series of calculations and then pass the value to the next layer, wherein the calculation process is S-excitation function or called the logical excitation function.Forward propagation for
