Bayesian Continual Imputation and Prediction For Irregularly Sampled Time Series Data

ICASSP 2022accepted

Learning from irregularly sampled, streaming, multi-variate time-series data with many missing values is a very challenging task. In this paper, we propose a Bayesian Continual Imputation and Prediction for Time-series Data (B-CIPIT), for learning from a sequence of time-series tasks. First, we deve…

Incremental Context Aware Attentive Knowledge Tracing

ICASSP 2022accepted

Knowledge Tracing is the prediction of the future performance of a learner, given the past performance. The existing knowledge tracing models represent the training data and does not generalize when there is a drift in the data distribution. We first empirically demonstrate an evolving Knowledge Tra…

Online Continual Learning Using Enhanced Random Vector Functional Link Networks

ICASSP 2022accepted

We propose an online continual learning algorithm based on an enhanced Random Vector Functional Link Network (OCL-eRVFL), that learns a sequence of tasks continually, where each task is defined by streaming data with each sample arriving once and only once. As data for a new task in domain increment…
