Multi-view and Cross-view Brain Decoding

no code implementations COLING 2022 Subba Reddy Oota, Jashn Arora, Manish Gupta, Raju S. Bapi

(2) Our extensive analysis across 9 broad regions, 11 language sub-regions and 16 visual sub-regions of the brain help us localize, for the first time, the parts of the brain involved in cross-view tasks like image captioning, image tagging, sentence formation and keyword extraction.

Enhancing Healthcare with EOG: A Novel Approach to Sleep Stage Classification

no code implementations25 Sep 2023 Suvadeep Maiti, Shivam Kumar Sharma, Raju S. Bapi

We introduce an innovative approach to automated sleep stage classification using EOG signals, addressing the discomfort and impracticality associated with EEG data acquisition.

Deep Neural Networks and Brain Alignment: Brain Encoding and Decoding (Survey)

no code implementations17 Jul 2023 Subba Reddy Oota, Manish Gupta, Raju S. Bapi, Gael Jobard, Frederic Alexandre, Xavier Hinaut

In this survey, we will first discuss popular representations of language, vision and speech stimuli, and present a summary of neuroscience datasets.

Cross-view Brain Decoding

no code implementations18 Apr 2022 Subba Reddy Oota, Jashn Arora, Manish Gupta, Raju S. Bapi

Also, the decoded representations are sufficiently detailed to enable high accuracy for cross-view-translation tasks with following pairwise accuracy: IC (78. 0), IT (83. 0), KE (83. 7) and SF (74. 5).

Visio-Linguistic Brain Encoding

no code implementations COLING 2022 Subba Reddy Oota, Jashn Arora, Vijay Rowtula, Manish Gupta, Raju S. Bapi

In this paper, we systematically explore the efficacy of image Transformers (ViT, DEiT, and BEiT) and multi-modal Transformers (VisualBERT, LXMERT, and CLIP) for brain encoding.

Expert2Coder: Capturing Divergent Brain Regions Using Mixture of Regression Experts

no code implementations26 Sep 2019 Subba Reddy Oota, Naresh Manwani, Raju S. Bapi

In this paper, we achieve this by clustering similar regions together and for every cluster we learn a different linear regression model using a mixture of linear experts model.

Mixture of Regression Experts in fMRI Encoding

no code implementations26 Nov 2018 Subba Reddy Oota, Adithya Avvaru, Naresh Manwani, Raju S. Bapi

We argue that each expert learns a certain region of brain activations corresponding to its category of words, which solves the problem of identifying the regions with a simple encoding model.

Learning Photography Aesthetics with Deep CNNs

2 code implementations13 Jul 2017 Gautam Malu, Raju S. Bapi, Bipin Indurkhya

To obtain both accuracy and human interpretation of the score, we advocate learning the aesthetic attributes along with the prediction of the overall score.
