Fuse and Attend: Generalized Embedding Learning for Art and Sketches

no code implementations20 Aug 2022 Ujjal Kr Dutta

While deep Embedding Learning approaches have witnessed widespread success in multiple computer vision tasks, the state-of-the-art methods for representing natural images need not necessarily perform well on images from other domains, such as paintings, cartoons, and sketch.

Seeing Objects in dark with Continual Contrastive Learning

no code implementations6 Dec 2021 Ujjal Kr Dutta

We propose a novel, contrastive learning method to align the latent representations of a pair of real and synthetic images, to make the detector robust to the different domains.

Semi-Supervised Metric Learning: A Deep Resurrection

no code implementations10 May 2021 Ujjal Kr Dutta, Mehrtash Harandi, Chellu Chandra Sekhar

In this paper, we address the problem of Semi-Supervised DML (SSDML) that tries to learn a metric using a few labeled examples, and abundantly available unlabeled examples.

Buy Me That Look: An Approach for Recommending Similar Fashion Products

1 code implementation26 Aug 2020 Abhinav Ravi, Sandeep Repakula, Ujjal Kr Dutta, Maulik Parmar

The novelty and strength of our method lies in its capability to recommend similar articles for all the fashion items worn by the model, in addition to the primary article corresponding to the query.

Unsupervised Deep Metric Learning via Orthogonality based Probabilistic Loss

no code implementations22 Aug 2020 Ujjal Kr Dutta, Mehrtash Harandi, Chellu Chandra Sekhar

As obtaining class labels in all applications is not feasible, we propose an unsupervised approach that learns a metric without making use of class labels.

Affinity guided Geometric Semi-Supervised Metric Learning

no code implementations27 Feb 2020 Ujjal Kr Dutta, Mehrtash Harandi, Chellu Chandra Sekhar

In this paper, we revamp the forgotten classical Semi-Supervised Distance Metric Learning (SSDML) problem from a Riemannian geometric lens, to leverage stochastic optimization within a end-to-end deep framework.

A Probabilistic approach for Learning Embeddings without Supervision

no code implementations17 Dec 2019 Ujjal Kr Dutta, Mehrtash Harandi, Chandra Sekhar Chellu

This restricts their applicability for large datasets in new applications where obtaining labels require extensive manual efforts and domain knowledge.
