sentence The main task of pattern recognition is to design a classifier that is invariant to these transformations, with the following three techniques: Structural invariance: The design of the structure has taken into account the insensitivity to the transformation, and the disadvantage is that the number of network connections becomes large Training invariance: Different sample training parameters for the same target; disadvantage: It is not guaranteed that the tr

Stanford University-machine learning public class-2. Supervised learning applications • Gradient descent

The study of this class, I believe that generally on the statistics or logistics related courses should be known to some students. Although the knowledge involved in class is very basic, it is also very important.Based on the collection of some house price related data, the linear regression algorithm is used to forecast the house price.In order to facilitate the training deduction of the algorithm, a lot of symbols of the standard provisions, from which also learned some knowledge, later in the

randomly groups the data to the extent that training intensive accounts for 70% of the original data (this ratio can vary depending on the situation), and the test error is used as the criterion when selecting the model. The question comes from the Stanford University Machine Learning course on Coursera, which is described as follows: the size and price of the

Preliminary introductionSupervised learning: Given a DataSet and know what its correct output should be like, feedback (feedback), divided into Regression (regressioin): Map input to a continuous output value. Classification (classification): Map output to discrete output values. Unsupervised learning: Given a data set, it is not known what the correct output is, no feedback, divided into

A classical algorithm for machine learning and Python implementation--clustering and K-means and two-K-means clustering algorithm

SummaryClustering is unsupervised learning ( unsupervised learning does not rely on pre-defined classes or training instances with class tags), it classifies similar objects into the same cluster, it is observational learning, rather than example-based learning, which is somewhat like a fully automated classification.

name. However, this is a standard term that people use in machine learning, so we don't have to worry about why people call it. Summary: when solving the housing price prediction problem, we actually want to "Feed" the training set to our learning algorithm, and then learn a hypothesis H, then we input the size of the house we want to predict into H as t

What is "large-scale machine learning"

In the massive data scenario, the value of the large-scale machine learning method to fully exploit the data set has been widely used in many companies, and the relevant information has been many, but still not very system. The door by my permission, reprinted the large-scale machine learning field of 2 excellent prac

accuracy accuracy rate to measure the performance of the algorithm. Typically, we set up a test set to test network performance. The test set does not intersect with the training set, the validation set (the training set contains the data for training learning, the validation set is used to select the optimal parameters, etc.). Many times we will find that performance is a difficult problem to quantify. In supervised

Today begins to learn pattern recognition with machine learning pattern recognition and learning (PRML), chapter 5.1,neural Networks Neural network-forward network.

Feedforward network, for example, we look at the typical two-layer network of Figure 5.1, and examine a hidden-layer element, if we take the symbol of its input parameter all inverse, take the tanh function as an example, we will get the opposite excitation function value, namely Tanh (−a) =−tanh (a). And then the unit all the output connection weights are reversed, we can get the same output, that is to say, there are two different sets of weights can be obtained the same output value. If ther

50-60 components.For text data, after converting the text to a sparse matrix, use Singular Value decomposition (SVD). A TRUNCATEDSVD can be found in the Scikit-learn.    In general, the SVD component that is useful for TF-IDF is 120-200. Exceeding this number may improve performance, but it will not be sustainable and the cost of computing power will increase.After evaluating the performance of the model, we then expand the database so that we can ev

Neural network and support vector machine for deep learningIntroduction: Neural Networks (neural network) and support vector machines (SVM MACHINES,SVM) are the representative methods of statistical learning. It can be thought that neural networks and support vector machines both originate from the Perceptual machine (Perceptron). Perceptron is a linear classific

These algorithms are more complex and superior, and generally do not require manual learning rate, which is faster than gradient descent algorithms. These include:Bounded gradient(Conjugate gradient ),Local Optimization Method(Broyden Fletcher Goldfarb shann, BFGS) andLimited Memory Local Optimization Method(L
