Original: Image classification in 5 MethodsAuthor: Shiyu MouTranslation: He Bing Center
Image classification, as the name suggests, is an input image, output to the image content classification of the problem. It is the core of computer vision, which is widely used in practice.
The traditional method of image classification is feature description and detection, such traditional methods may be effective for some simple image classification, but the traditional classification method is overwhelmed

algorithms typically merge input data by either a central point or a hierarchical approach. So the clustering algorithm tries to find the intrinsic structure of the data in order to classify the data in the most common way.

, B is the model parameter, W is the weight or weight vector, B is biased, W X is expressed as the inner product. Geometrically, the W x+b=0 corresponds to a super-plane of the feature space, W is the normal vector of the super-plane, and B is the intercept of the super-plane. That is, finding a hyper-plane separates the positive and negative instances of the data.2. Perceptual Machine Learning Strategy2.1

Artificial neural network is a huge branch of machine learning, there are hundreds of kinds of different algorithms.

Python Tools for machine learningPython is one of the best programming languages out there, with a extensive coverage in scientific Computing:computer VI Sion, artificial intelligence, mathematics, astronomy to name a few. Unsurprisingly, this holds true to machine learning as well.Of course, it has some disadvantages too; One of which is, the tools and libraries

This data set of 20 Web news sites collects nearly 20,000 news articles. This data set is often used for document classification and clustering experiments, and Scikit-learn provides an easy way to download and read datasets. We will train a perceptron to identify three

then applying them to new data. This is why it is common practice to evaluate an algorithm in machine learning by splitting the dataset into two datasets, one of which is called the training set, which is used to learn the properties of the data, and the other is called the test set, which tests those properties on the test set.loading a sample data setScikit-le

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.
8 tactics to Combat imbalanced Classes on Your machine learning Datasetby Jason Brownlee on August learning ProcessHave this happened?You is working on your dataset. You create a classification model and get 90% accuracy immediately. "Fantastic" you think. You dive a little deeper and discover this 90% of the data belongs to one class. damn!This is a example of a
