JetLOV: Enhancing Jet Tree Tagging through Neural Network Learning of Optimal LundNet Variables

1 code implementation24 Nov 2023 Mauricio A. Diaz, Giorgio Cerro, Jacan Chaplais, Srinandan Dasmahapatra, Stefano Moretti

Machine learning has played a pivotal role in advancing physics, with deep learning notably contributing to solving complex classification problems such as jet tagging in the field of jet physics.

Probabilistic Weight Fixing: Large-scale training of neural network weight uncertainties for quantization

1 code implementation24 Sep 2023 Christopher Subia-Waud, Srinandan Dasmahapatra

Weight-sharing quantization has emerged as a technique to reduce energy expenditure during inference in large neural networks by constraining their weights to a limited set of values.

MatSpectNet: Material Segmentation Network with Domain-Aware and Physically-Constrained Hyperspectral Reconstruction

1 code implementation21 Jul 2023 Yuwen Heng, Yihong Wu, Jiawen Chen, Srinandan Dasmahapatra, Hansung Kim

The network leverages the principles of colour perception in modern cameras to constrain the reconstructed hyperspectral images and employs the domain adaptation method to generalise the hyperspectral reconstruction capability from a spectral recovery dataset to material segmentation datasets.

DBAT: Dynamic Backward Attention Transformer for Material Segmentation with Cross-Resolution Patches

1 code implementation6 May 2023 Yuwen Heng, Srinandan Dasmahapatra, Hansung Kim

By analysing the cross-resolution features and the attention weights, this paper interprets how the DBAT learns from image patches.

Rotation-Scale Equivariant Steerable Filters

1 code implementation10 Apr 2023 Yilong Yang, Srinandan Dasmahapatra, Sasan Mahmoodi

When conventional CNNs are applied to histopathology image analysis, the generalization performance of models is limited because 1) a part of the parameters of filters are trained to fit rotation transformation, thus decreasing the capability of learning other discriminative features; 2) fixed-size filters trained on images at a given scale fail to generalize to those at different scales.

Scale-Equivariant UNet for Histopathology Image Segmentation

no code implementations10 Apr 2023 Yilong Yang, Srinandan Dasmahapatra, Sasan Mahmoodi

Digital histopathology slides are scanned and viewed under different magnifications and stored as images at different resolutions.

ADS_UNet: A Nested UNet for Histopathology Image Segmentation

no code implementations10 Apr 2023 Yilong Yang, Srinandan Dasmahapatra, Sasan Mahmoodi

Nested arrangements of these encoder and decoder maps give rise to extensions of the UNet model, such as UNete and UNet++.

Weight Fixing Networks

1 code implementation24 Oct 2022 Christopher Subia-Waud, Srinandan Dasmahapatra

Rather than a channel or layer-wise encoding, we look to lossless whole-network quantisation to minimise the entropy and number of unique parameters in a network.

Optimising 2D Pose Representation: Improve Accuracy, Stability and Generalisability Within Unsupervised 2D-3D Human Pose Estimation

no code implementations1 Sep 2022 Peter Hardy, Srinandan Dasmahapatra, Hansung Kim

With a maximum architecture capacity of 6 residual blocks, we evaluate the performance of 5 models which each represent a 2D pose differently during the adversarial unsupervised 2D-3D HPE process.

Low Entropy Deep Networks

no code implementations29 Sep 2021 Chris Subia-Waud, Srinandan Dasmahapatra

We design the approach to realise four model outcome objectives: i) very few unique weights, ii) low-entropy weight encodings, iii) unique weight values which are amenable to energy-saving versions of hardware multiplication, and iv) lossless task-performance.

Can Super Resolution be used to improve Human Pose Estimation in Low Resolution Scenarios?

no code implementations5 Jul 2021 Peter Hardy, Srinandan Dasmahapatra, Hansung Kim

Second, the keypoint detection performance gained is dependent on that persons pixel count in the original image prior to any application of SR; keypoint detection performance was improved when SR was applied to people with a small initial segmentation area, but degrades as this becomes larger.

Generalisation and the Geometry of Class Separability

no code implementations NeurIPS Workshop DL-IG 2020 Dominic Belcher, Adam Prugel-Bennett, Srinandan Dasmahapatra

Recent results in deep learning show that considering only the capacity of machines does not adequately explain the generalisation performance we can observe.

A phenomenological cluster-based model of Ca2+ waves and oscillations for Inositol 1,4,5-trisphosphate receptor (IP3R) channels

no code implementations11 Sep 2018 Svitlana Braichenko, Atul Bhaskar, Srinandan Dasmahapatra

Clusters of IP3 receptor channels in the membranes of the endoplasmic reticulum (ER) of many non-excitable cells release calcium ions in a cooperative manner giving rise to dynamical patterns such as Ca2+ puffs, waves, and oscillations that occur on multiple spatial and temporal scales.
