What are two models?
We have come to these two concepts from a few words:1, machine learning is divided into supervised machine learning and unsupervised machine learning;2, supervised machine learning is known as training set data categories to train the classifier, unsupervised machine
Machine learning is divided into supervised machine learning, unsupervised machine learning, and semi-supervised machine learning. The criterion for dividing it is whether the training sample contains human-labeled results. (1) Supervised machine learning: a function is lear
Learning PHP focuses on sticking to the discussion and learning php methods. I believe that choosing a language is not based on its background and long history, but more importantly, its practicality. even if it is a brilliant history, I believe that you have chosen a language instead of looking at its background and long history. What's more important is its practicality, the flashy language, even if it is
First, bulk learningIn the bulk method of supervised learning, the adjustment of the prominent weights of multilayer perceptron occurs after all n examples of the training sample set , which constitute a round of training. In other words, the cost function of bulk learning is defined by the average error energy. The synaptic value adjustment of multilayer Perceptron is based on round-turn . Accordingly, a
Background:As a programmer, the technology around us is constantly being upgraded.Take the web, the first only HTML, then have CSS, and then have Ajax and so on. Now the total amount of knowledge accumulated in web development is very large. So much knowledge to learn swarmed, it is easy to let us at a loss, do not know where to learn from, like a headless fly.Recently, there have been other lab classmates came to me to ask how to get started a new field, but also found their roommates all day w

This article shows that the performance of the second-class classifier can be achieved through unlabeled dataStructuredTo improve the processing process, that is, if you know that the tag of a sample has restrictions on the tag of other samples, then the data is structured.
In this paper, we propose that P-N learning uses labeled and unlabeled samples to train the second-
the similarities between practicing playing basketball and learning experience in a teacher's blog?In fact, I think learning every skill is connected. The 1th is to let oneself interested in this skill, have interest, will greatly increase the initiative of learning. 2nd, the acquisition of each skill needs a lot of practice, quantitative change is the precondit

However, I think the process of table tennis
Machine Learning is to study how computers simulate or implement human learning behaviors to acquire new knowledge or skills and reorganize existing knowledge structures to continuously improve their own performance. It is the core of artificial intelligence and the fundamental way to make computers intelligent. It is applied in various fields of artificial intelligence. It mainly uses induction, synthesis,

On-policy: The policy (value function) that generates the sample is the same as the policy (value function) used when updating parameters on the network. Typical for the Saras algorithm, based on the current policy directly perform a motion selection, and then update the current policy with this sample, so that the generation of sample policy and learning policy the same, the algorithm is On-policy algorithm. This method will encounter the contradicti
1. Research background and rationale
1958, Rosenblatt proposed Perceptron model (ANN)In 1986, Hinton proposed a deep neural network with multiple hidden layers (MNN)In the 2006, Hinton Advanced Confidence Network (DBN), which became the main frame of deep learning.Then, the efficiency of this algorithm is validated by Bengio Experiment 2.3 classes of depth learning models

Discriminant analysis is mainly in the statistics over there, so I am not very familiar with the temporary find statistics Department of the Boudoir Honey made up a missed lesson. Here we are now learning to sell.
A typical example of discriminant analysis is linear discriminant analysis (Linear discriminant analyses), referred to as LDA.
(notice here not to be confused with the implied Dirichlet distribution (latent Dirichlet allocation), although
First, we look at the new progress of target detection from CVPR2016. The 2016 CVPR conference target detection method is mainly based on convolution neural network framework, Representative work has resnet (in faster r-cnn ResNet replacement Vgg), YOLO (regression detection framework), locnet (more accurate positioning), Hypernet (High level information of neural network is advantageous to the identification, the bottom characteristic is advantageous to the localization, the low layer character

To now supervised learning has basically finished, this blog is mainly to write about the theory of machine learning, that is, when to use what learning algorithm, what kind of learning algorithms have what characteristics or advantages. At the time of fitting, how to choose the fitting model is actual

Naive Bayesian classifier is a set of simple and fast classification algorithms. There are many articles on the Internet, such as this one is relatively good: 60140664. Here, I'm going to sort it out as I understand it.In machine learning, we sometimes need to solve classification problems. That is, given a sample's eigenvalues (Feature1,feature2,... feauren), we want to know which category label the sample belongs to (Label1,label2,... Labeln). That
I recently read ng's deep learning tutorial and seeSelf-taught LearningSome concepts are unfamiliar. As a part of paying off the technical debt, I spent half an afternoon searching for several terms. If I want to use them later, I will try again.
