The first day of CNN Basics From:convolutional Neural Networks (LeNet)
neuro-Cognitive machines .The source of CNN's inspiration has been very comprehensive in many papers, and it is the great creature that found receptive Field (the sensation of wild cells). Based on this concept, a neuro-cognitive machine is proposed. Its main function is to recept part of the image information (or characteristics), and then through the hierarchical submission o
, forcing the algorithm to adjust the score according to the size of the data set of the different classifications. This is not the ideal solution.
In correspondence with simplicity (naive), a text classifier does not attempt to understand the meaning of a sentence, but simply classifies it. It is important to understand that the so-called intelligent chat robot does not really understand the human language, but that is another matter.

The basic overview of neural networks and neural network models are not carefully introduced here. A detailed introduction to the introduction of the neural network and its model is presented in the details of Daniel Ng, Stanford University. This paper mainly introduces the
current classification method is the number of hidden layers to distinguish whether "depth". When the number of hidden layers in a neural network reaches more than 3 layers, it is called "deep neural Network" or "deep learning".Uh deep learning, it turns out to be so simple.If you have time, you are advised to play mo

CV is an important direction of deep learning, CV generally includes: image recognition, target detection, neural style conversion
Traditional neural network problems exist: the image of the input dimension is larger, as shown, this causes the weight of the W dimension is larger, then he occupies a larger amount of memory, calculate W calculati

Proper weight initialization can prevent gradients from exploding and disappearing. For Relu activation functions, weights can be initialized to:
Also known as "he initialization". For Tanh activation functions, the weights are initialized to:
Also known as "Xavier initialization". You can also use the following formula to initialize:
In the above formula, L refers to the first layer of the neural
