Web3 mei 2024 · Feature Selection Library. Feature Selection Library (FSLib 2024) is a widely applicable MATLAB library for feature selection (attribute or variable selection), capable of reducing the problem of high dimensionality to maximize the accuracy of data models, the performance of automatic decision rules as well as to reduce data acquisition cost. WebWe may want to reduce the dimensions of our data, for example using PCA or MDS algorithms. reduce_dimensions takes a tibble, column names (as symbols; for sample, transcript and count) and a method (e.g., MDS or PCA) as arguments and returns a tibble with additional columns for the reduced dimensions.
