In this paper, a neural competitive learning tree is introduced as a computationally attractive
scheme for adaptive density estimation and novelty detection. The learning rule yields
equiprobable quantization of the input space and provides an adaptive focusing mechanism
capable of tracking time-varying distributions. It is shown by simulation that the neural tree
performs reasonably well while being much faster than any of the other competitive learning
algorithms.
