Portföy

Used: YOLO, Bi-LSTM Architecture & Attention mechanism

We propose Attention Grounder (AttnGrounder), a single-stage end-to-end trainable model for the task of visual grounding. Visual grounding aims to localize a specific object in an image based on a given natural language text query. Unlike previous methods that use the same text representation for every image region, we use a visual-text attention module that relates each word in the given query with every region in the corresponding image for constructing a region-dependent text representation. Furthermore, for improving the localization ability of our model, we use our visual-text attention module to generate an attention mask around the referred object. The attention mask is trained as an auxiliary task using a rectangular mask generated with the provided ground-truth coordinates. We evaluate AttnGrounder on the Talk2Car dataset and show an improvement of 3.26% over the existing methods.

Visual Grounding - Detecting objects using Language

Implemented a research paper: Scene Classification With Recurrent Attention of VHR Remote Sensing Images
Scene Classification With Recurrent Attention Models of VHR Remote Sensing Images. Used convolutional neural networks and recurrent neural networks. See https://github.com/vk-mittal14/Scene-Classification

Satellite Image Classification

Archaeologists usually find broken pieces of rare historic items after that they need to arrange the pieces in a particular order that makes some sense but the human mind is somewhat biased about the things that we see usually in our life thus in this project we aim to make a data-driven machine learning model that can solve 3*3 jigsaw puzzles. For this, we use a standard CNN model for extracting features from different regions of the image. After that, the Transformer model is used to relate distinct image regions with each other. Finally, the output of the Transformer is passed to an MLP layer that predicts the correct position for the image regions.

Jigsaw Solver using Neural Networks & Transformers

I designed a biometric system that takes the face as input and compares it with an already existing image of the owner to predict whether to allow access or not. As the person is wearing the matching complete faces is difficult. Therefore, we match the Forehead Wrinkles to predict whether two images are the same or not. Our pipeline consists of a forehand detection module and a matching module. For forehead detection, we finetune a pretrained Faster-RCNN model, and for forehead matching, we finetune a pretrained ResNet 50 with ArcFaceLoss.

Facial Biometric System using Forehead

Achieved 2nd position in a Deep Learning competition organized by Facebook AI Research.

In this challenge, our goal was to understand the spatial-temporal movement of eye gaze direction. Specifically, we need to predict the gaze direction for future time-steps based on the previously estimated gaze vectors. To this end, we use a two-stage approach in which we use: a ResNet18 backbone for predicting the gaze direction for an image and an LSTM model to capture the temporal dependency between the gaze direction and predict the future gaze direction.

Modeling Financial Uncertainty with Multivariate Temporal Entropy-based Curriculums

Conference on Uncertainty in Artificial Intelligence (UAI), 2021

We propose a novel multimodal curriculum learning approach: FinCLASS, which evaluates stock affecting signals via entropy-based heuristics and measures their linguistic and price-based complexities in a time-aware, hierarchical fashion. We show that training financial models can benefit by exposing neural networks to easier examples of stock affecting signals early during the training phase, before introducing samples having more complex linguistic and price-based temporal variations.
