A Simple Continuous Pitch Estimation Algorithm

A simple sketching algorithm for entropy estimation

We consider the problem of approximating the empirical Shannon entropy of a high-frequency data stream when space limitations make exact computation infeasible. It is known that αdependent quantities such as the Rényi and Tsallis entropies can be estimated efficiently and unbiasedly from low-dimensional α-stable data sketches. An approximation to the Shannon entropy can be obtained from either ...

Evaluation of a pitch estimation algorithm for speech emotion recognition

A Simple Actor-critic Algorithm for Continuous Environments

In reference to methods analyzed recently by Sutton et al, and Konda & Tsitsiklis, we propose their modification called Randomized Policy Optimizer (RPO). The algorithm has a modular structure and is based on the value function rather than on the action-value function. The modules include neural approximators and a parameterized distribution of control actions. The distribution must belong to a...

An iterative subspace-based multi-pitch estimation algorithm

In this paper, we present an iterative method for estimation of pitches from signals containing multiple sources using subspace techniques. The resulting estimator is termed Iterative Harmonic MUltiple SIgnal Classification (I-HMUSIC). Different modifications of I-HMUSIC are proposed that improve upon the classical MUSIC algorithm, including a computationally efficient method for noise subspace...
