. Random Search. Bengio in the random search for hyper-parameter optimization that random search is more efficient than gird search. In practice, it is usually the first time to use the Gird search method, to get all the candidate parameters, and then each time from the random selection of training. Bayesian optimization. Bayesian optimization, which takes into account the experimental result values corresponding to different parameters, saves time. Compared to the Internet search is simply the

-Carlo search tree turned out, scholars have seen the dawn. Then, the deep convolutional neural network comes into being, its own powerful automatic feature extraction ability solves the characteristic problem. Supplemented by self-game reinforcement learning, finally alphago birth announced that go has been "breached."Alphago is a go program developed by DeepMin

From self learning to deep network In the previous section, we used the self encoder to learn the characteristics of input to the Softmax or logistic regression classifier. These features are only learned using data that is not annotated. In this section, we describe how to fine-tune these features using the annotated data for further refinement. If you have a large number of tagged data, you can significan

In the case you need to use Big Data libraries, givepydoop and Pymongo a try.

Deep Learning: Now deep learning is very fire, along with the fire of an artificial intelligence, incredibly there is advertising that the AI era, the big Data era is not a few years, is it past? I personally think that at present, because the depth of

This article is a paper note for reference [1].convolutional Neural Network has a good performance in all tasks of supervised learning, but it is less in unsupervised learning field. The algorithm presented in this paper will have a combination of CNN in supervised learning and Gan in unsupervised learning. Under the non-CNN condition, Lapgan has achieved good results in the field of image resoluti

The structure of the residual network is used in a recent paper, so let's look at how the residual network works. The depth of the residual network can reach a heinous depth, how much more specific how good I did not say much.BackgroundWe all know that a deeper network can produce better results, but training a very

Deep Residual network in the 2015 ILSVRC competition to achieve the first achievement, ICLR2016 is also one of the key issues. Its main idea is simply to add a hop to bypass some layers of connectivity on a standard feedforward convolution network. Each bypass layer produces a residual block (residual blocks), and the convolution layer predicts the residuals of
