of the network is changed appropriately, so that the training process can converge faster and more stably.2.1.1 Increase momentum termFeedforward Network in the course of training, loss function often concussion, resulting in the training process is not convergent, in order to reduce the impact of this problem, you can try to use the smooth loss function of the oscillation curve to speed up the training process, through the design of low-pass filter

: Random initialization Loop until convergence { Each State transfer count in the sample is used to update and R Use the estimated parameters to update V (using the value iteration method of the previous section) According to the updated V to re-draw } In step (b) We are going to do a value update, which is also a loop iteration, in the previous section we solved v by initializing v t

Dialogue machine learning Great God Yoshua Bengio (Next)Professor Yoshua Bengio (Personal homepage) is one of the great Gods of machine learning, especially in the field of deep learning. Together with Geoff Hinton and Professor Yann LeCun (Yan), he created the deep

Hello everyone, I am mac Jiang. See everyone's support for my blog, very touched. Today I am sharing my handwritten notes while learning the cornerstone of machine learning. When I was studying, I wrote down something that I thought was important, one for the sake of deepening the impression, and the other for the later review.Online

converge or even diverge. .One thing worth noting:As we approach the local minimum, the guide values will automatically become smaller, so the gradient drop will automatically take a smaller amplitude, which is the practice of gradient descent. So there's actually no need to reduce the alpha in addition, we need a fixed (constant) learning rate α. 4. Gradient Descent linear regression (Gradient descent for Linear Regression) This is the method of us

of the most important aspects of machine learning is regularization and regularization, which will be detailed in subsequent chapters. Here is an intuitive understanding. The most common regularization item is the model of the constraint parameter. The following formula is used to constrain W: If y is a linear equation, the formula (1.4) is ridge regression. In Figure 1.7, we can see that the changed v

and regularization, which will be detailed in subsequent chapters. Here is an intuitive understanding. The most common regularization item is the model of the constraint parameter. The following formula is used to constrain W: If y is a linear equation, the formula (1.4) is ridge regression. In Figure 1.7, we can see that the changed value can have a huge impact on the model. When M = 9 is still used, it can be better fitted by adding it to the regularization item. Of

amounts of seemingly unrelated data processing, so need data mining technology to extract a variety of data and variables of the relationship between, so as to refine the data.Data mining is essentially a basis for machine learning and artificial intelligence, and his main goal is to extract the superset information from a variety of data sources, and then merge that information into patterns and relations

(SVM) training algorithm can be classified into one of two categories after being entered into a new case, making itself a non-probabilistic binary linear classifier.The SVM model represents the training cases as points in space, which are mapped to a picture, separated by an explicit, widest possible interval to differentiate between two categories.Algorithm explanation: Support vector machine for machine

Draw a map, there is the wrong place to welcome correct:In machine learning, features are critical. These include the extraction of features and the selection of features. They are two ways of descending dimension, but they are different:feature extraction (Feature Extraction): creatting A subset of new features by combinations of the exsiting features. In other words, after the feature extraction A feature

problem solution.Or simply, it can be understood that finding a reasonable hyper-plane in a high-dimensional space separates the data points, which involves the mapping of non-linear data to high-dimensional to achieve the purpose of linear divisible data.　　　　　　The above sample map is a special two-dimensional situation, of course, the real situation may be many dimensions. Start with a simple understanding of what a support vector is at a low latitu
