A Case Study in CUDA Kernel Fusion: Implementing FlashAttention-2 on NVIDIA Hopper Architecture using the CUTLASS Library

1 code implementation19 Dec 2023 Ganesh Bikshandi, Jay Shah

We provide an optimized implementation of the forward pass of FlashAttention-2, a popular memory-aware scaled dot-product attention algorithm, as a custom fused CUDA kernel targeting NVIDIA Hopper architecture and written using the open-source CUTLASS library.

Ordinal Classification with Distance Regularization for Robust Brain Age Prediction

1 code implementation IEEE/CVF Winter Conference on Applications of Computer Vision (WACV) 2023 Jay Shah, Md Mahfuzur Rahman Siddiquee, Yi Su, Teresa Wu, Baoxin Li

However, these methods are subject to an inherent regression to the mean effect, which causes a systematic bias resulting in an overestimation of brain age in young subjects and underestimation in old subjects.

Brainomaly: Unsupervised Neurologic Disease Detection Utilizing Unannotated T1-weighted Brain MR Images

1 code implementation18 Feb 2023 Md Mahfuzur Rahman Siddiquee, Jay Shah, Teresa Wu, Catherine Chong, Todd J. Schwedt, Gina Dumkrieger, Simona Nikolova, Baoxin Li

Harnessing the power of deep neural networks in the medical imaging domain is challenging due to the difficulties in acquiring large annotated datasets, especially for rare diseases, which involve high costs, time, and effort for annotation.

Process Design and Economics of Production of p-Aminophenol

no code implementations29 Oct 2021 Chinmay Ghoroi, Jay Shah, Devanshu Thakar, Sakshi Baheti

Para-Aminophenol is one of the key chemicals required for the synthesis of Paracetamol, an analgesic and antipyretic drug.

Causal Impact Of European Union Emission Trading Scheme On Firm Behaviour And Economic Performance: A Study Of German Manufacturing Firms

no code implementations16 Aug 2021 Nitish Gupta, Jay Shah, Satwik Gupta, Ruchir Kaul

In this paper, we estimate the causal impact (i. e. Average Treatment Effect, ATT) of the EU ETS on GHG emissions and firm competitiveness (primarily measured by employment, turnover, and exports levels) by combining a difference-in-differences approach with semi-parametric matching techniques and estimators an to investigate the effect of the EU ETS on the economic performance of these German manufacturing firms using a Stochastic Production Frontier model.

Study Of German Manufacturing Firms: Causal Impact Of European Union Emission Trading Scheme On Firm Behaviour And Economic Performance

no code implementations16 Aug 2021 Nitish Gupta, Ruchir Kaul, Satwik Gupta, Jay Shah

The results based on the nonparametric nearest neighbor matching suggest a statistically significant positive effect of the EU ETS on the economic performance of the regulated firms during Phase I of the EU ETS.

Algorithmic canonical stratifications of simplicial complexes

1 code implementation20 Aug 2018 Ryo Asai, Jay Shah

We introduce a new algorithm for the structural analysis of finite abstract simplicial complexes based on local homology.
