How to understand the status of NLP: see some tips for the latest doctoral dissertationIt may be a shortcut to look at the current status of an area and see the latest doctoral dissertation. For example, there are children's shoes asked how to understand the State-of-the-art of NLP, in fact, Stanford, Berkeley, CMU, JHU and other schools recently selected doctoral theses, the field of mainst

1. OverviewConvolution neural network features: On the one hand, the connection between the neurons is non-fully connected, on the other hand, the weights of the connections between some neurons in the same layer are shared (i.e. the same).Left: The image has 1000*1000 pixels, there are 10^6 of hidden layer neurons, to be fully connected, there are 1000*1000*100000=10^12 weight parametersRight: There are al

BP (back propagation) network is the 1986 by the Rumelhart and McCelland, led by the team of scientists, is an error inverse propagation algorithm training Multilayer Feedforward Network, is currently the most widely used neural network model. BP network can learn and store

Python uses numpy to flexibly define the neural network structure. This document describes how to flexibly define the neural network structure of Python Based on numpy. We will share this with you for your reference. The details are as follows: With numpy, You can flexibly define the

For example, entity recognition and entity standardization Joint learning, Word segmentation and POS tagging joint learning and so on. Recently, the research

For example,

The following figure shows the implementation of a back propagation algorithm for a three-layer neural network: Each neuron is composed of two cells. One is the weight and the input signal. The other is the nonlinear element, called the excitation function. The signal e is the excitation signal. y = f (e) is the output of the non-linear element, which is the output of the neuron. In order to

Turn from: The Heart of the machine Introduction Frankly speaking, I can't really understand deep learning for a while. I look at relevant research papers and articles and feel that deep learning is extremely complex. I try to understand neural networks and their variants, but still feel difficult. Then one day, I decided to start with a step-by-step basis. I break down the steps of technical operations and manually perform these steps (and calcula
