Answer Mining from a Pool of Images: Towards Retrieval-Based Visual Question Answering

no code implementations29 Jun 2023 Abhirama Subramanyam Penamakuri, Manish Gupta, Mithun Das Gupta, Anand Mishra

We study visual question answering in a setting where the answer has to be mined from a pool of relevant and irrelevant images given as a context.

Determinantal Point Process as an alternative to NMS

1 code implementation26 Aug 2020 Samik Some, Mithun Das Gupta, Vinay P. Namboodiri

We present a determinantal point process (DPP) inspired alternative to non-maximum suppression (NMS) which has become an integral step in all state-of-the-art object detection frameworks.

$c^+$GAN: Complementary Fashion Item Recommendation

no code implementations13 Jun 2019 Sudhir Kumar, Mithun Das Gupta

We present a conditional generative adversarial model to draw realistic samples from paired fashion clothing distribution and provide real samples to pair with arbitrary fashion units.

Re-evaluating ADEM: A Deeper Look at Scoring Dialogue Responses

no code implementations23 Feb 2019 Ananya B. Sai, Mithun Das Gupta, Mitesh M. Khapra, Mukundhan Srinivasan

ADEM(Lowe et al. 2017) formulated the automatic evaluation of dialogue systems as a learning problem and showed that such a model was able to predict responses which correlate significantly with human judgements, both at utterance and system level.

Doc2Im: document to image conversion through self-attentive embedding

no code implementations8 Nov 2018 Mithun Das Gupta

In this paper we propose a completely novel direction to text classification research, wherein we convert text to a representation very similar to images, such that any deep network able to handle images is equally able to handle text.

Solve-Select-Scale: A Three Step Process For Sparse Signal Estimation

no code implementations16 May 2016 Mithun Das Gupta

In the theory of compressed sensing (CS), the sparsity $\|x\|_0$ of the unknown signal $\mathbf{x} \in \mathcal{R}^n$ is of prime importance and the focus of reconstruction algorithms has mainly been either $\|x\|_0$ or its convex relaxation (via $\|x\|_1$).

KL Divergence Based Agglomerative Clustering for Automated Vitiligo Grading

no code implementations CVPR 2015 Mithun Das Gupta, Srinidhi Srinivasa, Madhukara J., Meryl Antony

In this paper we present a symmetric KL divergence based agglomerative clustering framework to segment multiple levels of depigmentation in Vitiligo images.
