Gaussian Multipole Model (GMM).
An electrostatic model based on charge density is proposed as a model for future force fields. The model is composed of a nucleus and a single Slater-type contracted Gaussian multipole charge density on each atom. The Gaussian multipoles are fit to the electrostatic potential (ESP) calculated at the B3LYP/6-31G* and HF/aug-cc-pVTZ levels of theory and tested by comparing electrostatic dimer ene...
متن کاملThe Approach of Speaker Diarization by Gaussian Mixture Model (GMM)
Speaker identification is an important activity in the process of speaker diarization. We need to model the speaker by Gaussian mixture model (GMM) for speaker identification purpose. Large GMM is called as a Universal Background Model (UBM) which is adapted into each speaker model for speaker identification purpose. This paper focuses on speech clustering for speaker diarization. The speaker d...
متن کاملAtomic forces for geometry-dependent point multipole and Gaussian multipole models
In standard treatments of atomic multipole models, interaction energies, total molecular forces, and total molecular torques are given for multipolar interactions between rigid molecules. However, if the molecules are assumed to be flexible, two additional multipolar atomic forces arise because of (1) the transfer of torque between neighboring atoms and (2) the dependence of multipole moment on...
متن کاملConfidence Interval Assessment for Charpy Impact Energy Predictions – A Gaussian Mixture Model (GMM)-Based Approach
One of the obstacles of applying data-driven models in industry is the lack of confidence in the accuracy of the model predictions. One way of overcoming this is by adding a confidence interval on the predictions. In this paper, we propose a new approach for the confidence interval assessment for model predictions based on a Gaussian Mixture Model (GMM) framework. The advantages of the presente...
متن کاملThe Sequential GMM: A Gaussian Mixture Model Based Speaker Verification System that Captures Sequential Information
1 Introduction This report presents a novel speaker verification system that generates a new feature set that captures long duration speaker identifying characteristics while taking advantage of the well-established and well-studied Gaussian Mixture Model system (GMM). Much of the innovation in the system is contained in the intelligent exploitation of traditional cepstral features such that te...
