Summary 0000144: FIXED: bug in mlpbase unit
Description "TanH" activation function was incorrectly calculated for arguments less than -100 (it was +1 instead of -1). This error was unlikely to trigger because of inputs normalization and task regularization, which make hard to achive such low inputs during normal conditions.

This bug was introduced in the ALGLIB 2.1.0.

Thanks to Andrei Rizhkovich for pointing out this bug.
