Graduate Research Assistant Jan 2020 - Present
Syracuse University College of Engineering and Computer Science

Research Project 1 - Step Counting and Speed detection
Worked on a project which focuses on predicting the step counts and the person's walking speed based on the accelerometer data of the wrist & waist. Prepared the raw accelerator data into features of a specific window sizes. Fetched the data within the boundary of window sizes and converted those into tensors. Implemented CNN as baseline model and Prototypical Learning (Few Shots learning) using PyTorch. Able to achieve 96% test accuracy and 99.5% validation accuracy.

Research Project 2 - Early age stammering prediction in children
Working on a project which helps to detect/ predict stammering in children using their free speech and scripted samples. Implementing a Multiple Instance Learning attention-based model to fulfill the task.

Mobile Application Developer Dec 2018 - Jan 2020
Indian Institute of Technology – Mumbai, India

Built a hybrid mobile application using Flutter to help people (mostly children) with severe speech or language problem. The application contains important words and enhanced illustrations to help them learn and communicate with the outside world. It contains more than 10,000 icons carefully separated in 35+ categories and subcategories. All the icons are also segregated by the their type. Built various plugins for improving the efficiency of application by approx 35%. Taking the targeted audience into consideration and their requirement, built two special keyboard serial ABC and qwerty with simplified keys. Simplified sentence construction for the children by generating live suggestion of words using natural language processing. Deployed beta version of the application which helped to identify bugs and functionality issues and later published the live version for the same on Google Play store as “Jellow Plus”

Music Tagging and Similarity Analysis for Recommendation System

Computational Intelligence in Pattern Recognition Springer Published on AUGUST 2019

Many of the websites follow the system of retrieving and recommending music based on the metadata. Metadata is generally a text file that attached to the music file has title and genre. Without attached metadata, it is very difficult for such websites to recommend or retrieve music. A regularly utilized rundown of the fundamental components incorporates pitch, timber, surface, volume, span, and frame. In the proposed methodology to process such a vast amount of data, the distributed storage and data processing systems like Hadoop and Spark has been used. Hadoop Distributed File System has been used for storing the music files and extracting feature information. Kafka queues has been used for asynchronous feature extraction in the background and finally Spark has been used for feature analysis using machine learning algorithms. This Proposed automated system for assigning genres for music provides very promising accuracy with a high true positive value.

Mining data from Twitter

Fetching textual data from twitter is really important for a project sometimes where people's opinion or crowd's view is needed. Through this blog, I had tried explaining all the concepts necessary for mining data from twitter including getting an API key and access token from the twitter developer dashboard and writing python code for fetching tweets.

Deploy Django project on IIS server

I wrote this blog after struggling a lot for weeks for configuring and deploying the Django project on the IIS server. When I was successful in deploying the project, I wrote the important steps and measures which I took during the process and tried to write those in the blog so that it can help people. The blog highlights all the important steps required for enabling IIS server and configuring the server for the deployment.
