Package: T1FF Title: Type-1 Fuzzy Functions for Classification, Regression, and Forecasting Version: 0.1.0 Authors@R: person("Nihat", "Tak", email = "nihattak@gmail.com", role = c("aut", "cre")) Description: Fits Type-1 Fuzzy Function models for binary classification, numeric regression, and time-series forecasting with user-supplied temporal predictors. The package combines fuzzy C-means memberships, nonlinear membership transformations, cluster-specific linear or support vector machine models, and membership-weighted predictions. It also provides model evaluation, validation, K-fold and stratified K-fold tuning, and repeated nested cross-validation with task-appropriate metrics. The regression workflow can be used for forecasting when temporal dependence is represented by lagged or seasonal predictors and assessment partitions preserve chronological order.
