运用统计与机器学习分析数据及建模

Statistics and Machine Learning Toolbox™ 提供用来描述、分析数据和对数据建模的函数和应用程序。您可以使用用于探查数据分析的描述性统计和绘图,使用概率分布拟合数据,生成用于 Monte Carlo 仿真的随机数,以及执行假设检验。回归和分类算法用于依据数据执行推理并构建预测模型。

对于多维数据分析,Statistics and Machine Learning Toolbox 提供特征选择、逐步回归、主成分分析 (PCA)、正则化和其他降维方法,从而确定影响您的模型的变量或特征。

该工具箱提供了受监督和不受监督机器学习算法,包括支持向量机 (SVM)、促进式 (boosted) 和袋装 (bagged) 决策树、k-最近邻、k-均值、k-中心点、分层聚类、高斯混合模型和隐马尔可夫模型。许多统计和机器学习算法可以用于大到无法在内存中存储的数据集的计算。
