Hi! I am Gunjan Chhablani, currently an ML Engineer at Oracle India Pvt. Ltd. where I work on building and deploying machine learning models for NLP. I graduated from BITS Pilani Goa in 2020, with a B.E. in Computer Science. In my free time I work on CV/NLP research projects.
I am extremely interested in deep learning and its applications and use my free time to work on research projects. My main research interest lies in the intersection of computer vision and natural language processing, and towards explaining the systems in these domains. I also work on adding models and features to 🤗datasets and 🤗transformers. Check the models that I have added here: VisualBert, PLBart, FNet.
In the little personal time that I get, I love working out, reading self-help books, watching a bit of Netflix, going out for a stroll, and listening to music/podcasts.
Feel free to hit me up for a discussion about any of the above, or just to say hi!

Superpixel-based Knowledge Infusion in Deep Neural Networks for Image Classification
We combine superpixel information with CNNs using differet kinds of GNNs to enhance the representation learned by the CNN. This helps us improve the classification performance on several tasks which we show in the paper.
Multitask Prompted Training Enables Zero-Shot Task Generalization
I contributed to prompting of the T0pp model on zero-shot generalization of transformer models to several tasks using HuggingFace datasets and Jinja templates. The model can be found here. This model is 16x smaller than GPT-3 but outperforms it on several tasks.
DRIFT: A Toolkit for Diachronic Analysis of Scientific Literature
We developed an open source toolkit called DRIFT for diachronic analysis of scientific literature using TWEC model for temporal word embeddings. We consolidated 10 different analysis methods with visualizations, including acceleration plot, semantic drift, wordclouds, tracking trends, LDA analysis, etc.
My team and I (part of what we call the “Language Research Group”) worked on making this tool using Streamlit. Our paper was accepted at EMNLP Demo 2021.
Datasets: A Community Library for Natural Language Processing
I contributed several datasets to the 🤗 Datasets and several fixes and features. I was one of the top-15 contributors and one of the authors of the paper. Our paper received the best paper award at EMNLP 2021 System Demonstrations track.
Toxic Spans Detection
This is a competition hosted for the workshop SemEval-21. My team and I (part of what we call the “Language Research Group”) along with Prof. Shan Suthaharan, worked on analyzing span prediction and token classification approaches on BERT for this task, along with a few hybrid approaches including multi-span detection, span+token detection and BERT with LSTM CRF.
Reading Comprehension of Abstract Meaning
This is a competition hosted for the workshop SemEval-21. My team and I (part of what we call the “Language Research Group”) along with Prof. Tirtharaj Dash. We devised several systems with augmentations and hypernym/hyponym information, statistical analysis for imperceptibility, and propose an idea to get the region in sentences with maximum relevant context to the question answered.
