1. Training error: The error of the learner in the training set, also known as "experience Error"2. Generalization error: The error of the learner on the new sampleObviously, our goal is to get a better learner on a new sample, which is a small generalization error.3. Overfitting: The learner learns the training sample too well, leading to a decline in generalization performance (learning too much ...). Let me think of some people bookworm, reading de

structure as follows.What effect does this autoencoder have on machine learning?1) for supervised learning: This information-preserving NN's hidden layer structure + weight is a reasonable conversion of the original input, equivalent to learning the expression of data in the structure2) for unsupervised

train streaming data and make predictionsIn the following example, we train a perceptron to categorize the datasets of 20 news categories. 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 news categories: Rec.sports.hockey, Rec.sport.baseball, and Rec.auto. Scikit-learn's perc

say we have some data points, and now we use a straight line to fit these points, so that this line represents the distribution of data points as much as possible, and this fitting process is called regression.In machine learning tasks, the training of classifiers is the process of finding the best fit curve, so the optimization algorithm will be used next. Before implementing the algorithm, summarize some

Machine learning Notes (i)Today formally began the study of machine learning, in order to motivate themselves to learn, but also to share ideas, decided to send their own experience of learning to the Internet to let everyone share.Bayesian learningLet's start with an exampl

The biggest feature of Elm is that the traditional neural network, especially the tow-layer feedforward neural Network (SLFNS), Elm is faster than the traditional learning algorithm.ELM is a new fast

, there are n single classifiers, each single classifier has an equal error rate, and the single classifier is independent of each other, error rate is irrelevant. With these assumptions, we can calculate the error probability of the integration model:If n=11, the error rate is 0.25, to integrate the result prediction error, at least 6 single classifier prediction results are incorrect, the error probability is:Integration result error rate is only 0.034 oh, much smaller than 0.25.
