(that is, Xi in {1,..., | v|} Value in | V| is the vocabulary of the lexicon), n-word messages will be represented by a vector of length n, and the length of the vectors for different articles will probably not be the same.In the multiple event model, we assume that this is the case with the message: first determine whether this is a spam message through P (Y), and then independently determine each word by multiple distributions P (x|y). The probability of the final generation of the entire mes

Absolute Percent error average absolute percent errors), defined as follows:Compared with Rmse,mape, the error of each point is normalized, eliminating the effect of absolute error caused by individual outliers.Summary and extensionIn this article, we are based on three hypothetical Hulu scenarios, mainly explaining the importance of evaluating the choice of indicators. Each evaluation indicator has its value, but if the model is evaluated only from a single evaluation index, it often results i

I=1~d, C=1~c    That is, FJ corresponds to all the labels, and each label has a D f. is different. This can automatically generate all the required FJ (washing machine corresponding to 1~d number, the hair dryer will automatically correspond to the d+1~2d number ...) ), this is a naive FJ Setup method, which considers that some items in FJ

Coursera Machine Learning Course note--Linear Models for classification

In this section, a linear model is introduced, and several linear models are compared, and the linear regression and the logistic regression are used for classification by the conversion error function.More important is this diagram, which explains why you can use linear regression or a logistic regression to replace linear classificationThen the stochastic gradient descent method is introduced, which is an improvement to the gradient descent method,

Machine learning methods: from linear models to neural networks

Discovery modeThe linear model and the neural network principle and the goal are basically consistent, the difference manifests in the derivation link. If you are familiar with the linear model, the neural network will be well understood, the model is actually a function from input to output, we want to use these models to find patterns in the data, to discover the existence of the function dependencies, of course, if the data itself exists such a fun
