Many toolbox algorithms can be used on data sets that are too big to be stored in memory. Native Simulink blocks let you use predictive models with simulations and Model-Based design. You can apply interpretability techniques such as partial dependence plots, Shapley values and LIME, and automatically generate C/C++ code for embedded deployment. The toolbox provides supervised, semi-supervised, and unsupervised machine learning algorithms, including support vector machines (SVMs), boosted decision trees, shallow neural nets, k-means, and other clustering methods. Regression and classification algorithms let you draw inferences from data and build predictive models either interactively, using the Classification and Regression Learner apps, or programmatically, using AutoML.įor multidimensional data analysis and feature extraction, the toolbox provides principal component analysis (PCA), regularization, dimensionality reduction, and feature selection methods that let you identify variables with the best predictive power. You can use descriptive statistics, visualizations, and clustering for exploratory data analysis fit probability distributions to data generate random numbers for Monte Carlo simulations, and perform hypothesis tests. Samples: Many samples that you can also download for free.Statistics and Machine Learning Toolbox™ provides functions and apps to describe, analyze, and model data. Multi-Image Analysis: Time-series, multiblock scenarios.

Spatial Attributes: Particle counting, thresholding, homogeneity assessment (GLCM, Macropixels, Fractal dimension).Ĭreation of Libraries: Pixel selection tools, mean areas and sub-areas.

Machine Learning: Regression (PLS, PCR, MLR) and Classification (SIMCA, PLS-DA, SVM, KNN). In this case, pca returns the principal components based on the correlation matrix. Spectral and Spatial pre-processing Methods: Binning, cropping, spectral range selection, spikes and dead pixels removal, masking tools (using up to 7 different methodologies), morphological operations (erosion, dilation, opening, closing, filling holes, elimination of regions, spectral preprocessing (Smoothing, SNV, MSC, Derivatives, Auscaling).ĭata Mining: Exploratory (PCA, sPCA, Evolving Factor Analysis), Clustering (K-Means, Fuzzy Clustering), Spectral Unmixing (MCR-ALS, endpoint members), Classical Least Squares, Libraries/correlations (Spectral Angle Mapper, Pearson's Correlation Coefficients). This MATLAB function returns the principal component coefficients. It has powerful visualization and interaction tools implemented. is a Graphical User-friendly Interface (GUI) for the analysis of multispectral and hyperspectral images.
