Locally Weighted Learning(LWL,局部加权学习) 3. Regularization Algorithms(正则化算法) 正则化是对另一种方法(通常是回归方法)的扩展,使基于其复杂性的模型受到惩罚,支持更简单的模型,这些模型在泛化能力方面也比较好。 常见的正则化算法包括: Ridge Regression(岭回归算法) Least Absolute Shrinkage and Selection Op...
An important step in generating predictive models is selecting the correct machine learning algorithm to use, a choice which can have a seemingly out-sized effect on model performance and efficiency. This selection can even determine the success of the most basic of predictive tasks: whether a mod...
Systems and methods of selecting machine learning models/algorithms for a candidate dataset are disclosed. A computer system may access historical data of a set of algorithms applied to a set of benchmark datasets; select a first algorithm of the set of algorithms; apply the first algorithm to ...
HeatWave AutoML automates the machine learning lifecycle, including algorithm selection, intelligent data sampling for training, feature selection, and tuning, often saving even more time and effort. The payoff for machine learning is the ability to analyze and interpret large amounts of data quickly...
Feature selection refers to the process of applying statistical tests to inputs, given a specified output. The goal is to determine which columns are more predictive of the output. TheFilter Based Feature Selection componentin the designer provides multiple feature selection algorithms to choose from...
The correct use of model evaluation, model selection, and algorithm selection techniques is vital in academic machine learning research as well as in many industrial settings. This article reviews different techniques that can be used for each of these three subtasks and discusses the main advantages...
in-database machine learning withHeatWave MySQLnegates the need to move data to a separate system for machine learning, which can help increase security, reduce costs, and save time. HeatWave AutoML automates the machine learning lifecycle, including algorithm selection, intelligent data sampling for...

[82]. Therefore, the RF learning model with multiple decision trees is typically more accurate than a single decision tree based model [106]. To build a series of decision trees with controlled variation, it combines bootstrap aggregation (bagging) [18] and random feature selection [11]. It...
(1983), we categorize the identified research contributions according to the used machine learning method/algorithm (e.g., decision trees and neural networks), the application in the constraint solving context (e.g., algorithm selection and learning of heuristics), and the used evaluation metrics ...
