I've been focusing on CNN implementations for a while, looking at Caffe's code and Convnet2 's code. At present, the content of the single-machine multi-card is more interested, so pay special attention to Convnet2 about MULTI-GPU support.where Cuda-convnet2 's project address is published in: Google Code:cuda-convnet2A more important paper on MULTI-GPU is: one weird trick for parallelizing convolutional neural NetworksThis article will also give an a

envy its "local tyrants" behavior, If there is a nvlink, there is obviously another good way to do it.Of course, wanting to use nvlink also means new investments, and Nvidia's existing product line supports deep learning, which users can choose to do as appropriate. For more in-depth knowledge of hardware selection, you can refer to the blog post written by Kaggle player Tim Dettmers: The full version of the Deep Learning hardware guide.The other is digits, a multi-in-one graphics system design

Artificial neural Network (Artificial neural netwroks) Notes--2.1.3 steps in the discrete multi-output perceptron training algorithm are multiple judgments, so we say it's a discrete multiple output perceptron. Now take the formula Wij=wij+α (YJ-OJ) Xi instead of that step The effect of the difference between Yj and Oj on Wij is manifested by alpha (YJ-OJ) XI

Recently in the study of Artificial neural network (Artificial neural netwroks), make notes, organize ideas Discrete single output perceptron algorithm, the legendary MP Two-valued Network: The value of the independent variable and its function, the value of the vector component only takes 0 and 1 functions, vectors

AA = Np.random.randn (3, 3= NP.RANDOM.RANDN (3, 1= a*bA. This will trigger the broadcast mechanism, so B is copied three times, becomes (3,3), * represents the matrix corresponding element multiplied, so the size of C will be (3, 3)B. This will trigger the broadcast mechanism, so B is duplicated three times, becomes (3, 3), * represents matrix multipli

1 Introduction Remember when I first contacted RoboCup 2 years ago, I heard from my seniors that Ann (artificial neural network), this thing can be magical, he can learn to do some problems well enough to deal with. Just like us, we can learn new knowledge by studying. But for 2 years, I've always wanted to learn about Ann, but I haven't been successful. The main reason for this is that the introduction o

In the vggnet, 2014 ilsvrc competition model, image recognition is slightly inferior to googlenet, but it has a great effect in many image conversion learning problems (such as object detection ). Fine-tuning of Convolutional Neural Networks What is fine-tuning?Fine-tuning is to use the weights or partial weights that have been used for other targets, pre-trained models, and start training as the initial values. So why don't we rando

A reference to the artificial neural network should think of three basic knowledge points: One is the neuron model, the other is the neural network structure, and the third is the learning algorithm. There are many kinds of neural networks, but the classification basis canno

-------------------------------------------------------------------------------- Visualization of weight values After training, the network weights can be visualized to judge the model and whether it owes (too) fit. Well-trained network weights usually appear to be aesthetically pleasing, smooth, whereas the opposite is a noisy image, or the pattern correlation is too high (very regular dots and stripes), o
