Versa Chat Assistant A GenAI powered multimodal and multilingual chat assistant to automate customer 360 profile across all Jio Retail Platforms (Ajio, Reliance Digital, Netmeds, Jiomart) Jio Indic Lens Indic Search and Discovery platforms which supports billions of SKUs under one hood. This solution helps discover hidden insights applying GenAI and AI Search solutions to revolutionize customer search and purchase journey. (This technology has been patented by Jio Platforms.) Jio Search and Discovery Platform Deployed highly scalable ML pipeline (PySpark) using Elastic Search, Flask and Redis for Search Engine Auto-Correction and Auto-Suggestion tasks used for Auto Spell Correction, Auto Suggestion, Hierarchial Ranking of results. Business impact : improvement of recall rate to 0.94 and CTR score of 0.44 ! Jio RecoAI User Recommender system for JioMart powering brands, products, all product level category substitutes for Knowledge graph entity recognition. Jio Ashtang Project (Jio Brain) Extracted growth rules using In-house formulation (combining Lift score, Log-odd ratio, Confidence score) for Personalised Product Feed Sugesstion Pipeline. ML Research Projects @JIO - * Model Retrofitting Pipeline - Building SOTA model for Twitter Hatespeech, SemEval Dataset using model retrofitting techniques. Improved existing model accuracy by 6% . * Indic Character Transition and Phonetic Variants using Gaussian Kernel Estimators - Character correction in spell variants across all indic dialects (hindi, marathi, bengali , etc.)

Honing Distributed Technology skills with Big Data (Pyspark) and applying Machine learning algorithms at scale for production. News-Entity Knowledge Graph(TAU) Developed News-Entity Knowledge Graph with entity nodes (such as NER, Category, Interest Groups, etc.), generated by association rules on user interests and their browsing history and trending NERs. User-Entity Recommendation Built User Recommendation Pipeline, using Geo Co-Located User Service, News-Entity Knowledge Graph and Marcov Chain Models based on User Events(Card-Clicks , Share , Like , etc). Publisher Sensitivity Model Analysed Publisher Data using Regression approach to rank and segregate spurious content (by highly bounced publishers) from magnanimous content (by highly sensitive publishers).

LDA Topic Modelling Clustering on Publisher Articles (documents) to extract top words (using SVD and prob. distribution matrices) and bucketing top words into 128 to 512 categories to classify and tag latest published articles into various categories (Sports, Politics, Finance, etc).

Speaker Recognition System ( IEEE Publication ) Research Work on Speaker Voice verification using Siamese Network (trained on persons' voice mel-spectrogram data on VGG-16 Model).

Working on Speaker recognition and speaker authentication .
