BACKGROUND Predicting species' potential geographical range by species distribution models (SDMs) is central to understand their ecological requirements. However, the effects of using different modeling techniques need further investigation. In order to improve the prediction effect, we need to assess the predictive performance and stability of different SDMs. METHODOLOGY We collected the dis...

The minimum average correlation energy (MACE) filter of [Mahal, Ravi], produces sharp correlation peaks over the recognition class in pattern recognition problems. It is known that the MACE filter of [Mahal, Ravi] can be formulated as a pre-whitening filter cascaded with a linear synthetic discriminant function. It will be shown that the MACE filter is equivalent to a linear associative memory ...
