Masked Multi-Step Probabilistic Forecasting for Short-to-Mid-Term Electricity Demand

no code implementations14 Feb 2023 Yiwei Fu, Nurali Virani, Honggang Wang

Models trainded with MMMPF can also generate desired quantiles to capture uncertainty and enable probabilistic planning for grid of the future.

Masked Multi-Step Multivariate Time Series Forecasting with Future Information

no code implementations28 Sep 2022 Yiwei Fu, Honggang Wang, Nurali Virani

Furthermore, once a neural network model is trained with MMMF, its inference speed is similar to that of the same model trained with traditional regression formulations, thus making MMMF a better alternative to existing regression-trained time series forecasting models if there is some available future information.

Uncertainty-aware Perception Models for Off-road Autonomous Unmanned Ground Vehicles

no code implementations22 Sep 2022 Zhaoyuan Yang, Yewteck Tan, Shiraj Sen, Johan Reimann, John Karigiannis, Mohammed Yousefhussien, Nurali Virani

We test the hypothesis that model trained on a single dataset may not generalize to other off-road navigation datasets and new locations due to the input distribution drift.

Adversarial Attacks with Time-Scale Representations

no code implementations26 Jul 2021 Alberto Santamaria-Pang, Jianwei Qiu, Aritra Chowdhury, James Kubricht, Peter Tu, Iyer Naresh, Nurali Virani

Third, we generate new adversarial images by projecting back the original coefficients from the low scale and the perturbed coefficients from the high scale sub-space.

Variational Encoder-based Reliable Classification

no code implementations19 Feb 2020 Chitresh Bhushan, Zhaoyuan Yang, Nurali Virani, Naresh Iyer

Machine learning models provide statistically impressive results which might be individually unreliable.

Justification-Based Reliability in Machine Learning

no code implementations18 Nov 2019 Nurali Virani, Naresh Iyer, Zhaoyuan Yang

To address this need, we link the question of reliability of a model's individual prediction to the epistemic uncertainty of the model's prediction.

Design of intentional backdoors in sequential models

no code implementations26 Feb 2019 Zhaoyuan Yang, Naresh Iyer, Johan Reimann, Nurali Virani

Recent work has demonstrated robust mechanisms by which attacks can be orchestrated on machine learning models.

Symbolic Analysis-based Reduced Order Markov Modeling of Time Series Data

no code implementations26 Sep 2017 Devesh K. Jha, Nurali Virani, Jan Reimann, Abhishek Srivastav, Asok Ray

In the second example, the data set is taken from NASA's data repository for prognostics of bearings on rotating shafts.
