Deep-Ensemble-Based Uncertainty Quantification in Spatiotemporal Graph Neural Networks for Traffic Forecasting

no code implementations4 Apr 2022 Tanwi Mallick, Prasanna Balaprakash, Jane Macfarlane

Our approach uses a scalable Bayesian optimization method to perform hyperparameter optimization, selects a set of high-performing configurations, fits a generative model to capture the joint distributions of the hyperparameter configurations, and trains an ensemble of models by sampling a new set of hyperparameter configurations from the generative model.

Posture and sequence recognition for Bharatanatyam dance performances using machine learning approach

no code implementations24 Sep 2019 Tanwi Mallick, Partha Pratim Das, Arun Kumar Majumdar

To develop an application for dance, three aspects of dance analysis need to be addressed: 1) Segmentation of the dance video to find the representative action elements, 2) Matching or recognition of the detected action elements, and 3) Recognition of the dance sequences formed by combining a number of action elements under certain rules.
