Hoang is strongest in algorithm development and coding for complex AI problems, including predictive and counterfactual reasoning, advanced prompt engineering, and LLM-based video question answering. Hoang has also worked with video processing pipelines that convert video into structured formats for machine-learning applications. At VinBigdata, Hoang developed and integrated aspect-based sentiment analysis models for VinBase, supporting Vietnamese-language chatbot applications including Vingroup’s ViVi system. Hoang coordinated four interns in labeling approximately 400,000 Vietnamese comment sentences related to VinFast cars and banking applications, contributing to results of 80% F1 for emotion classification and 72% F1 for opinion extraction. Hoang’s master’s thesis research on video question answering has been published. While leaning toward research-oriented roles, Hoang is open to applied AI work and adapts to company needs. ## Services - Thesis - Written Communication - Training - Communication - Computer Science - Analytical Skills - Computer Architecture - Statistics - Text Classification - C++ - Vietnamese - Big Data - Data Visualization - Data Processing - Knowledge Graphs - Research - Data Modeling - Python \(Programming Language\) - Machine Learning - Natural Language Processing \(NLP\) - Deep Learning - Data Science - Artificial Intelligence \(AI\) ## Highlights - Developed and integrated aspect-based sentiment analysis NLP models into VinBase at VinBigdata, supporting Vietnamese-language chatbot applications including Vingroup’s ViVi system. - Collaborated with senior engineers to prepare NLP components for deployment in an applied conversational AI system. - Researched Transformer-based models for aspect-based sentiment analysis and opinion mining on Vietnamese user comments. - Coordinated four interns in processing and labeling approximately 400,000 Vietnamese comment sentences related to VinFast cars and banking applications. - Achieved an 80% F1-score for emotion classification on the processed Vietnamese dataset. - Achieved a 72% F1-score for opinion extraction on the processed Vietnamese dataset. - Assisted in extending an aspect-based sentiment analysis model toward comparative opinion mining, achieving a 42.5% F1-score on English test data. - Built LLM-based video question answering systems using advanced prompting techniques. - Applied chain-of-thought prompting and question decomposition to AI tasks. - Processed video and converted it into structured formats for machine-learning applications. - Handled predictive and counterfactual reasoning tasks with AI models. - Published master’s thesis research on video question answering. ## Experience - **AI/NLP Engineer at VinBigdata** (2021-09-01–2022-07-01) — \- Developed and integrated NLP models for aspect-based sentiment analysis into VinBase, supporting Vietnamese-language chatbot applications including Vingroup’s ViVi system. - Collaborated with senior engineers to prepare NLP components for deployment in an applied conversational AI system. - Researched Transformer-based models for aspect-based sentiment analysis and opinion mining on Vietnamese user comments. - Coordinated a team of four interns to process and label approximately 400,000 Vietnamese comment sentences related to VinFast cars and banking applications. - Achieved 80% F1-score for emotion classification and 72% F1-score for opinion extraction on the processed Vietnamese dataset. - Assisted in extending the ABSA model toward comparative opinion mining, achieving 42.5% F1-score on English test data. ## Education - Master of Science - MS, Computer Science — University of Central Florida (2024-01-01–2026-05-01) - Bachelor of Science - BS, Knowledge Technology — VNUHCM - University of Science (2017-09-01–2022-03-01) ## FAQ ### What is Hoang's educational background?
