The TD_RandomProjectionMinComponents function calculates the minimum number of components required for applying RandomProjection on the given dataset for the specified epsilon(distortion) parameter value. The function estimates the minimum value of the NumComponents argument in the TD_RandomProjectionFit function for a given dataset. The function uses the Johnson-Lindenstrauss Lemma algorithm to calculate the value.
