2. How to classify real samples:
Iris DataSet, which is a very classic dataset, Scikit-learn the Basic sample datasets commonly used in tutorial. This paper focuses on the cross-validation (Zhouhuazhi-machine learning, which is a good summary of the model evaluation). Error: Training error, test error, generalization error. Our ultimate goal
What are machine learning?The definitions of machine learning is offered. Arthur Samuel described it as: "The field of study that gives computers the ability to learn without being explicitly prog Rammed. " This was an older, informal definition.Tom Mitchell provides a more modern definition: 'a computer program was sa
Azure Machine Learning ("AML") is a Web-based computer learning service that Microsoft has launched on its public cloud azure, a branch of AI that uses algorithms to make computers recognize a large number of mobile datasets. This approach is able to predict future events and behaviors through historical data, which is significantly better than traditional forms
training sample information, which are not detailed here. 1.3 main tasks of machine learningThe example above describes how machine learning solves the classification problem, and its main task is to divide the instances into appropriate sub - class. Another task of machine learni
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 specific data formats for
First, the machine learning algorithm engineers need to master the skills
Machine Learning algorithm engineers need to master skills including

is all 0. And because it can be deduced that b=1nz∗zt=wt∗ (1NX∗XT) w=wt∗c∗w, this expression actually means that the function of the linear transformation matrix W in the PCA algorithm is to diagonalization the original covariance matrix C. Because diagonalization in linear algebra is obtained by solving eigenvalue and corresponding eigenvector, the process of PCA algorithm can be introduced (the process is mainly excerpted from Zhou Zhihua's "machine
variable. For example, a label that represents the actual value of rainfall, a person's height, and so on.The first 5 algorithms we discussed in this blog-linear regression, logistic regression, CART (categorical regression tree), Naive Bayes, KNN (K-Nearest algorithm)-are examples of supervised learning.Integration (ensembling) is a supervised learning. This means predicting new samples by combining predictions from several different weak
