Databases Systems, 82/100, 2021
In this project we design the database schema and implement the relational schema, load the data into a DBMS, evaluate and optimize queries with query plan analysis in order to analyze the performance impact in Oracle SQL. The dataset contains a subset of data from the California Highway Patrol collected from the Statewide Integrated Traffic Records System (SWITRS), covering traffic collisions in the state of California in 2018. These reports have been collected by the Highway Patrol, recorded electronically for archival and preservation based on the forms filed by officers. This data has an immense value for urban planners and scientists that may want to analyze risks and how to improve the traffic situation and which factors or locations may be prevalent.

Vision Transformers for Analyzing High-Resolution Pathology Images

Master Thesis
Transformers are powerful models that can capture long-range dependencies between data using an attention mechanism. However, applying transformers to medical problems poses challenges due to the high-resolution and complexity of pathology images, as well as the scarcity and noise of labels. In this thesis, we have provided a comprehensive overview of the state-of-the- art transformers method for analyzing high-resolution pathology images, using the glioblastoma dataset IvyGAP and the renal cancer dataset as case studies. We have discussed how to pre- train transformers using self-supervised learning methods that can learn useful representations from unlabeled data. We have also explored how to find regions of interest within a whole slide image using different levels of supervision: self-supervised, weakly supervised and strongly supervised. We have demonstrated that transformers can provide a semantic understanding of the data and outperform convolutional-based models on downstream tasks such as classification and segmentation. Finally, we employ posterior networks to estimate the aleatoric and epistemic uncertainty of ViT predictions and evaluate their usefulness for clinical decision making. We propose a novel method to filter potentially mislabeled data in order to make more accurate and confident predictions. Our experiments show that our methods achieve state-of-the-art results on various glioblastoma tasks and provide meaningful insights into the behavior and limitations of ViTs for medical machine learning.

BERT fine-tuning for Sentimental Analysis with deployment using Ray Serve

Personal Project, 2022
This project has for purpose to practice the full pipeline of solving a problem using modern MLOPS tools. The pre-trained BERT weights have been fine-tuned on a sentimental analysis task on the iMDB dataset. Logging and hyper-parameter tunning has been done using W&B. A Docker image is available for production and deployment is done using Ray Serve to obtain a REST API.

Improving Domain Generalization for Deep Learning-Powered Cancer Cell Detectiong

Internship, 2022
In 2022, I have worked as a research & software intern at NEC Laboratories in Princeton, a brilliant research company along with world-renowned scientists. I have implemented and researched the various techniques of data augmentation to improve results on a complex multi-class segmentation problem. In the Medical Machine Learning department, I motivated the use of GANs to produce new samples for cancer detection, explored the use of self-supervised method such as MixMatch, and studied ways to make model more robust to domain generalization.
