from when pre-training the 150-16 network weight w from S2 to C3?First of all, if we have a total of m large picture as a training sample, then S2 the CPC to get 6*m feature map, its size is 14*14, and we convolution it to use the 5*5 size, and we input to the network is 150-dimensional, So it's definitely necessary to sub-sample the data. So we only need to sample this 6*m picture, each of the 6 features (6 sheets of the S2 layer) randomly sampling several 5*5 sizes (that is, they each sample

Machine learning and its application 2013 content introduction BooksComputer BooksMachine learning is a very important area of research in computer science and artificial intelligence. In recent years, machine learning has not only been a great skill in many fields of comput

Objective Machine learning is divided into: supervised learning, unsupervised learning, semi-supervised learning (can also be used Hinton said reinforcement learning) and so on. Here, the main understanding of supervision and unsu

AdaBoost generalization error rate is low, easy to encode, can be applied on most classifiers, no parameter adjustment, but sensitive to outliers. This method is not an independent method, but it must be based on the meta-method to improve efficiency. Personally, the so-called "AdaBoost is the

Google has a strong support in these three areas: Google not only has a rich variety of data resources, but also has a strong computer group to provide data storage in the dat

At present, the application of machine learning business is more in communication and finance.

WEEK1:Machine learning: A computer program was said to learn from experience E with respect to some class of tasks T and performance measure P, if Its performance on tasks in T, as measured by P, improves with experience E. Supervised learning:we already know what we correct output should look like. Regression:try to map input variables to some continuous function.

We will first perform linear regression on the data, that is, the first graph on the left. If we do this, we can obtain such a straight line that fits the data, but in fact this is not a good model. Let's look at the data. Obviously, as the area of the house increases, the changes in the housing price tend to be stable, or the more you move to the right
