Automatic Polyp Segmentation with Multiple Kernel Dilated Convolution Network

2 code implementations13 Jun 2022 Nikhil Kumar Tomar, Abhishek Srivastava, Ulas Bagci, Debesh Jha

The detection and removal of precancerous polyps through colonoscopy is the primary technique for the prevention of colorectal cancer worldwide.

PAANet: Progressive Alternating Attention for Automatic Medical Image Segmentation

no code implementations20 Nov 2021 Abhishek Srivastava, Sukalpa Chanda, Debesh Jha, Michael A. Riegler, Pål Halvorsen, Dag Johansen, Umapada Pal

We develop progressive alternating attention dense (PAAD) blocks, which construct a guiding attention map (GAM) after every convolutional layer in the dense blocks using features from all scales.

Exploiting Multi-Scale Fusion, Spatial Attention and Patch Interaction Techniques for Text-Independent Writer Identification

1 code implementation20 Nov 2021 Abhishek Srivastava, Sukalpa Chanda, Umapada Pal

Our methods are based on the hypothesis that handwritten text images have specific spatial regions which are more unique to a writer's style, multi-scale features propagate characteristic features with respect to individual writers and patch-based features give more general and robust representations that helps to discriminate handwriting from different writers.

AGA-GAN: Attribute Guided Attention Generative Adversarial Network with U-Net for Face Hallucination

no code implementations20 Nov 2021 Abhishek Srivastava, Sukalpa Chanda, Umapada Pal

The performance of facial super-resolution methods relies on their ability to recover facial structures and salient features effectively.

An Energy Efficient Health Monitoring Approach with Wireless Body Area Networks

no code implementations27 Sep 2021 Seemandhar Jain, Prarthi Jain, Prabhat K. Upadhyay, Jules M. Moualeu, Abhishek Srivastava

In addition to being able to handle streaming data, the model works within the resource-constrained environments of an LPU and eliminates the need of transmitting the data to a back-end cloud, ensuring further energy savings.

BEIR: A Heterogenous Benchmark for Zero-shot Evaluation of Information Retrieval Models

2 code implementations17 Apr 2021 Nandan Thakur, Nils Reimers, Andreas Rücklé, Abhishek Srivastava, Iryna Gurevych

To address this, and to facilitate researchers to broadly evaluate the effectiveness of their models, we introduce Benchmarking-IR (BEIR), a robust and heterogeneous evaluation benchmark for information retrieval.

Conditional Hybrid GAN for Sequence Generation

no code implementations18 Sep 2020 Yi Yu, Abhishek Srivastava, Rajiv Ratn Shah

Conditional sequence generation aims to instruct the generation procedure by conditioning the model with additional context information, which is a self-supervised learning issue (a form of unsupervised learning with supervision information from data itself).

Analysis and Design Considerations for Achieving the Fundamental Limits of Phase Noise in mmWave Oscillators with On-Chip MEMS Resonator

no code implementations13 May 2020 Abhishek Srivastava, Baibhab Chatterjee, Udit Rawat, Yanbo He, Dana Weinstein, Shreyas Sen

Very small electromechanical coupling coefficient in micro-electromechanical systems (MEMS) or acoustic resonators is quite of a concern for oscillator performance, specially at mmWave frequencies.

Understanding Script-Mixing: A Case Study of Hindi-English Bilingual Twitter Users

no code implementations LREC 2020 Abhishek Srivastava, Kalika Bali, Monojit Choudhury

Our analysis shows that both intra-sentential and inter-sentential script-mixing are present on Twitter and show different behavior in different contexts.
