machine learning bayes theorem

situation, to achieve a complete class of people, there is not a short time. But even so, machines that differ greatly from people's minds can still help our lives. For example, our commonly used online translation, search system, expert system, etc., are the product of machine learning.So, how to realize machine learning?On the whole,

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

is round and red, and the diameter is about 3 inches, the fruit may be apple. Even if these properties depend on each other, or depend on the existence of other features, the Naive Bayes classifier will assume that these properties individually imply that the fruit is an apple. Naive Bayesian models are easy to build and useful for large datasets. Although simple, but naive Bayesian performance is beyond the very complex classification method. Bayesi

Support vector machine-SVM must be familiar with machine learning, Because SVM has always occupied the role of machine learning before deep learning emerged. His theory is very elegant, and there are also many variant Release vers

Tags: basic machine learning Continue with the original algorithm: (5) Bayesian Method Bayesian algorithms are a class of algorithms based on Bayesian theorem. They are mainly used to solve classification and Regression Problems. Common algorithms include Naive Bayes, averaged one-dependence estimators, and Bayesi

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.2.2 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: Sensitive to parameter adjustment and kernel function selectio

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

In general, RBM is relatively independent of an algorithm, do not need to rely on too much prior knowledge.Basic concepts of RBMThe res

Scikit-learn (formerly Scikits.learn) is a open source machine learning library for the Python programming language. It features various classification, regression and clustering algorithms including support vector machines, logistic regre Ssion, naive Bayes, random forests, gradient boosting, K-means and DBSCAN, and is designed-interoperate with the Py

various machine learning fields, such as minimizing the maximum loss, sequential decision, and parameter estimation. Naive Bayes is one of them. This is also a type of algorithm.8.
