Accepted Paper: Radio Galaxy Classification at INNS DLIA 2023

/in , /by

Our research paper, ‘Morphological Classification of Radio Galaxies using Semi-Supervised Group Equivariant CNNs,’ has been accepted for presentation at the esteemed INNS Deep Learning Innovations and Applications (INNS DLIA 2023) workshop, which is part of the International Joint Conference on Neural Networks (IJCNN 2023). The paper will also be published in the renowned Procedia Computer Science journal!

In this study, we tackled the challenge of limited labeled data in radio galaxy classification by employing a cutting-edge semi-supervised learning approach. By harnessing the power of Group Equivariant Convolutional Neural Networks (G-CNNs) as encoders, we achieved impressive results in classifying radio galaxies into the well-known Fanaroff-Riley Type I (FRI) and Type II (FRII) categories.

Explainable Hate Speech Detection: ICML 2023 Workshop Acceptance

/in , /by

Recently, Md Fahim, RA of CCDS with co-authors from UToronto, IUT and Fordham University has a paper accepted in AI and HCI workshop of ICML 2023. The paper proposes an interpretability and explainability oriented model to detect hate speech utilizing the pre-trained large language models. It creates dynamic class specific conceptual subspaces from which class specific attention is obtained by projecting the contextual embedding onto those spaces. These attentions provide better explainability of the detection task.

Title: Holographic QFTs on AdS$_d$, wormholes and holographic interfaces.

arXiv preprint: https://arxiv.org/abs/2209.12094

We consider three related topics: (a) Holographic quantum field theories on AdS spaces. (b) Holographic interfaces of flat space QFTs. (c) Wormholes connecting generically different QFTs. We investigate in a concrete example how the related classical solutions explore the space of QFTs and we construct the general solutions that interpolate between the same or different CFTs with arbitrary couplings. The solution space contains many exotic RG flow solutions that realize unusual asymptotics, as boundaries of different regions in the space of solutions. We find phenomena like “walking” flows and the generation of extra boundaries via “flow fragmentation”.
