Task Aware Modulation using Representation Learning: An Approach for Few Shot Learning in Heterogeneous Systems

no code implementations7 Oct 2023 Arvind Renganathan, Rahul Ghosh, Ankush Khandelwal, Vipin Kumar

We present a Task-aware modulation using Representation Learning (TAM-RL) framework that enhances personalized predictions in few-shot settings for heterogeneous systems when individual task characteristics are not known.

Uncertainty Quantification in Inverse Models in Hydrology

no code implementations3 Oct 2023 Somya Sharma Chatterjee, Rahul Ghosh, Arvind Renganathan, Xiang Li, Snigdhansu Chatterjee, John Nieber, Christopher Duffy, Vipin Kumar

Our inverse model offers 3\% improvement in R$^2$ for the inverse model (basin characteristic estimation) and 6\% for the forward model (streamflow prediction).

Message Propagation Through Time: An Algorithm for Sequence Dependency Retention in Time Series Modeling

no code implementations28 Sep 2023 Shaoming Xu, Ankush Khandelwal, Arvind Renganathan, Vipin Kumar

Time series modeling, a crucial area in science, often encounters challenges when training Machine Learning (ML) models like Recurrent Neural Networks (RNNs) using the conventional mini-batch training strategy that assumes independent and identically distributed (IID) samples and initializes RNNs with zero hidden states.

Entity Aware Modelling: A Survey

no code implementations16 Feb 2023 Rahul Ghosh, HaoYu Yang, Ankush Khandelwal, Erhu He, Arvind Renganathan, Somya Sharma, Xiaowei Jia, Vipin Kumar

However, these entity characteristics are not readily available in many real-world scenarios, and different ML methods have been proposed to infer these characteristics from the data.

Probabilistic Inverse Modeling: An Application in Hydrology

no code implementations12 Oct 2022 Somya Sharma, Rahul Ghosh, Arvind Renganathan, Xiang Li, Snigdhansu Chatterjee, John Nieber, Christopher Duffy, Vipin Kumar

We propose uncertainty based learning method that offers 6\% improvement in $R^2$ for streamflow prediction (forward modeling) from inverse model inferred basin characteristic estimates, 17\% reduction in uncertainty (40\% in presence of noise) and 4\% higher coverage rate for basin characteristics.

Robust Inverse Framework using Knowledge-guided Self-Supervised Learning: An application to Hydrology

no code implementations14 Sep 2021 Rahul Ghosh, Arvind Renganathan, Kshitij Tayal, Xiang Li, Ankush Khandelwal, Xiaowei Jia, Chris Duffy, John Neiber, Vipin Kumar

Furthermore, we show that KGSSL is relatively more robust to distortion than baseline methods, and outperforms the baseline model by 35\% when plugging in KGSSL inferred characteristics.
