Looked into techniques that ensure factuality and toxicity Checks. Tools used were Langchain, LLama Index, Streamlit. LLM of choice was Mixtral. Currently Structuring company knowledge into knowledge graphs using local LLMs and Advanced Prompt Engineering for better RAG. Used Frameworks like RAGAS to evaluate outputs. Research & Evaluation: Keeping abreast new advancements in GenAI world, this include evaluating new Open Source LLM Models, Vector Databases and SOTA Techniques in the areas of Text and ImageNLP : headed multiple projects dealing with summarization, sentence similarity, topic modeling, topic classification, text generation, Machine Translation, evaluating word embeddingsModel Training & Evaluation: Spearheaded the training and fine-tuning of machine learning models, leveraging domain-specific data to optimize performance. Utilized diverse compute backends, including AWS, Runpod, Colab, and Azure, to ensure robust and scalable solutions. Adept in advanced techniques such as ensembling and hyperparameter tuning, enhancing model accuracy to over 85% and ensure there is no over or under-fittingContinuous Model Improvements using RLHF & DPO : Setup a internal framework using Argilla to improve specialised models with Human in LoopModel Deployments: Used Docker and Compose with managed GPU backends to create microservices (REST API)Experiment Tracking & Logging: Set up experiment tracking and model performance using Weights and BiasesFeature Engineering & Data Augmentation: Extensive Involvement in procedures like Dimensionality Reduction with PCA, LDA. Synthetic Data generation for Tabular data ensuring the same underlying distribution using Adverserial Techniques in cases where Data is scarce Show less
