Forecasting of Precipitation in India by Different Data Types using Investigation of Radial Basis Function Neural Network Model
TL;DR: In this paper, the Radial Basis Function Neural Network Model with back propagation algorithm was used to forecast the predication of rainfall for the state of Punjab, India in 2015.
Proceedings ArticleDOI
Analysis and Prediction of Stock Market Movements using Machine learning
TL;DR: In this paper , the authors analyze the historical data of some stock market companies between certain time periods and perform analysis by using a data science algorithm and check the accuracy of predictions, and then the prediction results are compared with other algorithms and the best possible algorithm is selected.

Acoustics of children's speech: developmental changes of temporal and spectral parameters.
TL;DR: The results confirm that the reduction in magnitude and within-subject variability of both temporal and spectral acoustic parameters with age is a major trend associated with speech development in normal children, and support the hypothesis of uniform axial growth of the vocal tract for male speakers.

Shape invariant time-scale and pitch modification of speech
Thomas F. Quatieri,R.J. McAulay +1 more
TL;DR: A time-scale modification system that preserves shape-invariant joint time- scale and pitch modification during voicing is developed using a version of the sinusoidal analysis-synthesis system that models and independently modifies the phase contributions of the vocal tract and vocal cord excitation.

Prosody modification using instants of significant excitation
K.S. Rao,B. Yegnanarayana +1 more
TL;DR: The proposed method for prosody (pitch and duration) modification using the instants of significant excitation of the vocal tract system during the production of speech is compared with linear prediction pitch synchronous overlap and add (LP-PSOLA) method.
Improving speech recognition for children using acoustic adaptation and pronunciation modeling.
TL;DR: This paper presents a preliminary study towards better acoustic modeling, pronunciation modeling and front-end processing for children’s speech, and introduction of pronunciation modeling shows promising performance improvements.
