Non-supervised learning:
In this learning mode, the input data part is identified, the part is not identified, the learning model can be used for prediction, but the model first needs to learn the internal structure of the data in order to reasonably organize the data to make predictions. The application scenarios include classification and regression, and t

There is a period of time does not dry goods, home are to be the weekly lyrics occupied, do not write anything to become salted fish. Get to the point. The goal of this tutorial is obvious: practice. Further, when you learn some knowledge about machine learning, how to deepen the understanding of the content through practice. Here, we make an example from the 2nd-part perceptron of Dr. Hangyuan Li's statist

A sensor is a linear classifier of the second-class Classification and belongs to a discriminant model (another is to generate a model ). Simply put, the objective is divided into two categories by using the input feature and the hyperplane. Sensor machines are the foundation of ne
Self-study machine learning three months, exposure to a variety of algorithms, but many know its why, so want to learn from the past to do a summary, the series of articles will not have too much algorithm derivation.We know that the earlier classification model-Perceptron (1957) is a linear classification model of class Two classification, and is the basis of later neural networks and support vector machin
Perception Machine (Perceptron)The Perceptron (Perceptron) was proposed by Rosenblatt in 1957 and is the basis of neural networks and support vector machines. Perceptron is a linear classification model of class Two classification, its input is the characteristic vector of the instance, the output is the class of the instance, and the value of +1 and 12 is taken. The perceptual machine corresponds to the se
machine learning is divided into two types: supervised learning and unsupervised learning . Next I'll give you a detailed introduction to the concepts and differences between the two methods. Supervised Learning (supervised learning

Originally this article is prepared for 5.15 more, but the last week has been busy visa and work, no time to postpone, now finally have time to write learning Spark last part of the content.第10-11 is mainly about spark streaming and Mllib. We know that Spark is doing a good job of working with data offline, so how does it behave on real-time data? In actual production, we often need to deal with the received data, such as real-time

In fact, it is a variant of the MDS algorithm, the same idea as the MDS, but in the calculation of the distance of the high-dimensional space is the geodesic distance, rather than the real expression of the European distance betwee
PremiseThis series of articles is not intended to be used to study the derivation of mathematical formulae, but to quickly implement the idea of machine learning in code. The main thing is to comb your thoughts.Perception MachineThe perception machine is to accept the data transmitted by each sensory element (neuron), which will produce corresponding behavior whe

General process for solving machine learning
Recent research on this one thing-the limit learning machine.
In many problems, I often encounter two problems, one is classification, the other is regression. To put it simply, the classification is to label a bunch of numbers, and the regression is to turn a number into a number.
Here we need to deal with the general dimension of the data is relatively high, in dealing with these two types of proble

assumptions tend to be 0, but the actual labels are 1, both of which indicate a miscarriage of judgment. Otherwise, we define the error value as 0, at which point the value is assumed to correctly classify the sample Y.Then, we can use the error rate errors to define the test error, that is, 1/mtest times the error rate errors of H (i) (xtest) and Y (i) (sum from I=1 to Mtest).Stanford University public Class machine
