design a system that allows it to learn in a certain way based on the training data provided; With the increase of training times, the system can continuously learn and improve the performance, through the learning model of parameter optimization, it can be used to predict the output of related problems. 4.

Machine Learning (machines learning, abbreviated ML) and computer vision (computer vision, or CV) are fascinating, very cool, challenging and a wide area to cover. This article has organized the learning resources related to machine lear
of human learning mechanisms, such as physiology and cognitive science. It establishes computational models or cognitive models for human learning, and develops various learning theories and methods, study general learning algorithms and perform theoretical analysis to esta
As the name implies, the purpose of machine learning is to allow machines to have the ability to learn, understand, and comprehend things similar to human beings. Imagine how important it is for a patient's recovery if a computer can summarize and sum up a large number of cancer treatment records, and be able to give appropriate advice and advice to a physician. In addition to the medical field, financial s

Step 1: Add a title for this experiment. This article is named "experiment by Jiahua" Step 2: Find the uploaded data on the left. The name is "UCI German credit card data". Drag the data to the intermediate workspace, the data description is displayed on the right. After the data enters the workspace, it is represented by a
1. What is machine learningMachine learning is the conversion of unordered data into useful information.The main task of machine learning is to classify and another task is to return.Supervised learning: It is called supervised learning
clusters. Clustering is when you don't know exactly how many classes the target database has, and you want to make all the records into different classes or clusters, and in this case, The similarity of a metric (for example, distance) is minimized between the same cluster and maximized among different clustering classes. Unlike classification, unsupervised learning does not rely on a predefined class or band-mark training instance, which needs to be
, so as to better identify the problem and adjust the model. The most noteworthy is the feature engineering , the characteristics of the design is often more like an art. In general or to accumulate more, more divergent thinking, hands-on to do, reflect on the summary, gradual.Review of each chapterGetting Started with 1.Python machine learning: This paper introduces the orientation of the book and

For a given set of data and problems, the machine learning method to solve the problem is generally divided into 4 steps: A Data preprocessing First, you must ensure that the data is in a format that meets your requirements. The standard data format can be used to fuse algorithms and data sources to facilitate matching operations. In addition, you need to prepare

Ah, throw them to the model, and then let the model to train to find good features", the idea that too young too naïve. Model training is just a tool, it is not Aladdin's lamp, can give you all the help, it is not a cow, you give it grass, it gives you milk. You need to give the model a high quality input, it can return you a perfect result. Model The model is based on training samples, objective functions and evaluation indicators of the three elements of
one. You need a method to quickly know whether an option is feasible. Therefore, you have introduced the machine learning diagnostic technique: As mentioned above, diagnosis tells you how to learnAlgorithmAnd provides guidance on improving the effectiveness of algorithms. Although the diagnosis takes some time, it is insignificant compared to trying the
and data mining:the overall goal of the data mining process are to extract Information from a data set and transform it to an understandable structure for further use.Machine learning also have intimate ties to optimization:? The three pillars:statistical modeling, feature selection, learning via optimization (Netflix prize)? Many learning problems is formulated
of a nonlinear function sigmoid, and the process of solving the parameters can be accomplished by the optimization algorithm. In the optimization algorithm, the gradient ascending algorithm is the most common one, and the gradient ascending algorithm can be simplified to the random gradient ascending algorithm.2.SVM (supported vector machines) Support vectors machine:Advantages : The generalization error rate is low, the calculation cost is small, the result is easy to explain. cons : Sensit
