Probabilistic Neighbourhood Component Analysis: Sample Efficient Uncertainty Estimation in Deep Learning

1 code implementation18 Jul 2020 Ankur Mallick, Chaitanya Dwivedi, Bhavya Kailkhura, Gauri Joshi, T. Yong-Jin Han

In this work, we show that the uncertainty estimation capability of state-of-the-art BNNs and Deep Ensemble models degrades significantly when the amount of training data is small.

Mix-n-Match: Ensemble and Compositional Methods for Uncertainty Calibration in Deep Learning

1 code implementation16 Mar 2020 Jize Zhang, Bhavya Kailkhura, T. Yong-Jin Han

We show that none of the existing methods satisfy all three requirements, and demonstrate how Mix-n-Match calibration strategies (i. e., ensemble and composition) can help achieve remarkably better data-efficiency and expressive power while provably maintaining the classification accuracy of the original classifier.

Deep Kernels with Probabilistic Embeddings for Small-Data Learning

1 code implementation13 Oct 2019 Ankur Mallick, Chaitanya Dwivedi, Bhavya Kailkhura, Gauri Joshi, T. Yong-Jin Han

Experiments on a variety of datasets show that our approach outperforms the state-of-the-art in GP kernel learning in both supervised and semi-supervised settings.

Reliable and Explainable Machine Learning Methods for Accelerated Material Discovery

no code implementations5 Jan 2019 Bhavya Kailkhura, Brian Gallagher, Sookyung Kim, Anna Hiszpanski, T. Yong-Jin Han

We also propose a transfer learning technique and show that the performance loss due to models' simplicity can be overcome by exploiting correlations among different material properties.
