COVID-19 Sentiment Analysis on AWS
I created a complete machine learning pipeline in AWS for tweet sentiment analysis regarding COVID-19. Also, I employed AWS EC2 to scrape and store data in the AWS S3 bucket, preprocessed data using Amazon EMR, and created and validated models using Amazon SageMaker. Finally, the predictions were shown on a Tableau dashboard.

Dataset of Handwritten Words
We collected a dataset of handwritten English words from more than 100 people by asking them to write English words. This small dataset can be used for handwritten words recognition. It is publicly available on Kaggle.

Analyzing the Performance of Cricket Players

I developed a model that estimates a cricket player's performance in a future match based on weather, pitch type, and prior performance. In addition, I created a model that could predict the outcome of a game based on ground factors and the past statistics of both teams' players.

Voice Digits Recognition API

This API transcribes the audio containing digit voices. I created the neural network that predicts the five digits spoken in the audio and developed the Flask API that efficiently generates inference.

The Russian Language Speech-to-text Model

I trained the speech-to-text model using multi-GPU on a Russian telephone dataset, performed the telephonic augmentation, and created multiprocessing supported scripts for training and validation. I also used subtitles as the labels to train a model on Russian audio movies, which was made possible with the help of CTC.

Optical Character Recognition (OCR)
This custom OCR, created using OpenCV in Python, converts images into English characters. I developed a script that takes an image input and predicts possible English characters in each line. I also trained connected component labeling (CCL) and convolutional neural network (CNN) to estimate characters.

Face Recognition Attendance System

A website I created enables instructors to mark the students' attendance by uploading an image of the classroom and the interference on low-quality images was improved using features like super-resolution (SR) imaging and image deblurring.

Kitchen Utensils Detection Using Raspberry Pi
A model I created predicts the utensil type through the live camera mounted on a Raspberry Pi and I used OpenCV to provide fast interference on the live feed, where the accuracy of a lower FPS is improved by fine-tuning a deep learning model on a custom dataset.

Eye Segmentation and Color Detection
This Python script segments and predicts an eye color from a 3D image of a face. An eye is segmented using the connected component labeling (CCL) and the circular Hough Transform (CHT) algorithm in OpenCV.

Signature Extraction and Recognition

I created an API that takes in a PDF document and compares it to the signatures in the database. It is accomplished by extracting signatures from a PDF file using OpenCV and passing each candidate's signature through a machine learning model that matches it with the signature database.

Optimizing Pickup and Delivery Points in a Ride-sharing Platform

This API estimates the most likely pickup and delivery points in the future based on the history of pickup and delivery points. This estimation is accomplished by clustering previous data and calculating new points based on the time of day.

Stable Diffusion Fine-tuning and Optimization

I created a PyTorch-lightning version to fine-tune a stable diffusion model and the purpose of this project was to use lightning optimization techniques, where the model was fine-tuned on a custom dataset and on a machine with A100 GPU.

API Creation for Virtual Try-On Models

I compared different available try-on models and performed inference using PyTorch and Python with 3D image processing to extract the mask of the garment. I also created API using Flask and a demo on a web app using React.
