Trains model with Labels (classes) and Source which can be continuous, categorical or ordinal data.

Pascal
procedure Train(srcContinuous: TMtx; srcCategorical: TMtxInt; srcCategoryCount: TVecInt; srcOrdinal: TMtxInt; srcLabels: TVecInt); override;
Description

Features (or attributes) are stored in rows. Column count is reflective of observation count and needs to match among continuous, categorical and ordinal data. You can convert features stored in columns in to features stored in rows by transposing the matrices. srcCategoryCount needs to store the total number of distinct category values. After the call, dstLabels holds results of prediction in one single row. Row count for individual source matrices can be zero, but column count must match. (Implements "Structure of Arrays" input.)
