Transfer Learning via Latent Dependency Factor for Estimating PM 2.5

no code implementations10 Apr 2024 Shrey Gupta, Yongbee Park, Jianzhao Bi, Suyash Gupta, Andreas Züfle, Avani Wildani, Yang Liu

We recognize this transfer problem as spatial transfer learning and propose a new feature named Latent Dependency Factor (LDF) that captures spatial and semantic dependencies of both domains and is subsequently added to the datasets.

Predictive Inference with Weak Supervision

no code implementations20 Jan 2022 Maxime Cauchois, Suyash Gupta, Alnur Ali, John Duchi

The expense of acquiring labels in large-scale statistical machine learning makes partially and weakly-labeled data attractive, though it is not always apparent how to leverage such data for model fitting or validation.

The $s$-value: evaluating stability with respect to distributional shifts

1 code implementation7 May 2021 Suyash Gupta, Dominik Rothenhäusler

We evaluate the performance of the proposed measure on real data and show that it can elucidate the distributional instability of a parameter with respect to certain shifts and can be used to improve estimation accuracy under shifted distributions.

Robust Validation: Confident Predictions Even When Distributions Shift

no code implementations10 Aug 2020 Maxime Cauchois, Suyash Gupta, Alnur Ali, John C. Duchi

One strategy -- coming from robust statistics and optimization -- is thus to build a model robust to distributional perturbations.

Knowing what you know: valid and validated confidence sets in multiclass and multilabel prediction

no code implementations21 Apr 2020 Maxime Cauchois, Suyash Gupta, John Duchi

We develop conformal prediction methods for constructing valid predictive confidence sets in multiclass and multilabel problems without assumptions on the data generating distribution.

Permissioned Blockchain Through the Looking Glass: Architectural and Implementation Lessons Learned

no code implementations20 Nov 2019 Suyash Gupta, Sajjad Rahnama, Mohammad Sadoghi

We show that designing such a well-crafted system is possible and illustrate that even if such a system employs a three-phase protocol, it can outperform another system utilizing a single-phase protocol.

Scaling Blockchain Databases through Parallel Resilient Consensus Paradigm

no code implementations3 Nov 2019 Suyash Gupta, Jelle Hellings, Mohammad Sadoghi

At the core of MultiBFT is an approach to continuously order the client-transactions by running several instances of the underlying BFT protocol in parallel.
