The role of cross-entropy
One of the most common ways to solve multi-classification problems with neural networks is to set N output nodes at the last layer, whether in shallow neural networks or in CNN, for example, the last output layer in alexnet has 1000 nodes:And even if the ResNet cancels the all-connected layer, it will have a 1000-node output layer at the end:
In general, the number of nodes in the
BP algorithm is one of the most effective multi-layer neural network learning methods, its main characteristic is the signal forward transmission, and the error after the propagation, through the constant adjustment of the network weight value, so that the final output of the network and the desired output as close as
There are infinitely many neural networks which can be obtained by any combination of the convolution layer, the pool layer and so on, and what kind of neural network is more likely to solve the real image processing problem. In this paper, a general model of convolution neural net
It took a week to learn about neural networks after soy sauce in the Knowledge Engineering Center. The teacher arranged a question and asked me to try it. I did a little simple. I conducted several groups of tests and wrote a summary report. I posted it here.
After more than a week of experimentation, I have a simple understanding of this issue. The following is my thoughts on this issue. In the last two days, I suddenly felt that the problem was much
BP (Back Propagation) network is a multi-layer feed-forward Network trained by the error inverse propagation algorithm, which was proposed by a team of scientists led by Rumelhart and mccelland in 1986, it is one of the most widely used neural networks. The BP network can learn and store a large number of input/output

Although the research and application of neural network has been very successful, but in the development and design of the network, there is still no perfect theory to guide the application of the main design method is to fully understand the problem to be solved on the basis of a combination of experience and temptation, through a number of improved test, finall
Deep learning "engine" contention: GPU acceleration or a proprietary neural network chip?Deep Learning (Deepin learning) has swept the world in the past two years, the driving role of big data and high-performance computing platform is very important, can be described as deep learning "fuel" and "engine", GPU is engine engine, basic all deep learning computing platform with GPU acceleration. At the same tim

Second, the database index is fast and complete, according to a thing can quickly associate with the principle of its occurrence. Third, the sensory ability is strong, palpation all sharp.

From the understanding of convolution nerves to the realization of it, before and after spent one months, and now there are still some places do not understand thoroughly, CNN still has a certain difficulty, not to see which blog and one or two papers on the understanding, mainly by themselves to study, read the recommended list at the end of the reference. The current implementation of the CNN in the Minit data set effect is good, but there are some bugs, because the recent busy, the
