) ^2\)To break it apart, it was \ (\frac1 2 \bar{x}\) where \ (\bar{x}\) is the mean of the squares of $h _θ (x_i)? Y_i $, or the difference between the predicted value and the actual value.This function is otherwise called the "Squared error function", or "Mean squared error". The mean is halved \ ((\frac1 2) \) as a convenience for the computation of the gradient descent, as the derivative Term of the square function would cancel out the \frac1 2\ . The following image summarizes what is the c

The process of building a machine learning algorithm: Quickly build a simple algorithm and test the performance of the algorithm with a cross-validation set. Draw the learning curve, check whether the algorithm has high variance or high deviation problem, so as to choose corresponding coping methods. Error analysis, to see the

In both industry and academia, machine learning is a hot direction, but academia and industry focus on machine learning, academia focuses on the study of machine learning theory, and industry focuses on how to solve practical prob

examples. Algorithms of the Intelligent Web (Smart Web algorithm) PDFAuthor Haralambos Marmanis, Dmitry Babenko. The formula in this book is a little bit more than "collective intelligence programming", the example of which is mostly the application on the Internet, to see the name. The disadvantage is that the matching code inside is BeanShell and not python or anything else. In general, this book is still suitable for beginners, and the same need

From Cold War to deep learning: An Illustrated History of machine translationSelected from vas3k.comIlya PestovEnglish Translator: Vasily ZubarevChinese Translator: Panda The dream of high quality machine translation has been around for many years and many scientists have contributed their time and effort to this dream. From early rule-based

Machine Learning (machines learning, ML) is a multidisciplinary interdisciplinary subject involving probability theory, statistics, approximation theory, convex analysis, algorithmic complexity theory and many other disciplines. Specialized in computer simulation or realization of human learning behavior, in order to a

. Optimal interval classifierThe optimal interval classifier can be regarded as the predecessor of the support vector machine, and is a learning algorithm, which chooses the specific W and b to maximize the geometrical interval. The optimal classification interval is an optimization problem such as the following:That is, select Γ,w,b to maximize gamma, while satisfying the condition: the maximum geometry in

statistical tests for each feature:false positive rate SELECTFPR, false discovery rate selectfdr, or family wise error selectfwe. The document says that if you use a sparse matrix, only the CHI2 indicator is available, and everything else must be transformed into the dense matrix. But I actually found that f_classif can also be used in sparse matrices.Recursive Feature elimination: Looping feature selectionInstead of examining the value of a variable individually, it aggregates it together for
