Data Scientist (Online Competitions/Projects)
Participated in various online data science competitions involving the development and fine-tuning of machine learning models using public text datasets. Key projects included sentiment analysis, text classification, topic modeling, and chatbot development, which required preparing training data, feature engineering, and evaluating model performance. These tasks involved iteratively labeling, annotating, and structuring textual datasets to achieve higher accuracy in NLP tasks. • Worked with real-world competition datasets from platforms like Kaggle and Analytics Vidhya. • Performed feature extraction, data labeling, and model evaluation for NLP applications. • Focused on sentiment analysis, classification, and recommendation systems leveraging textual data. • Utilized proprietary tools, Python, and relevant libraries for annotation and labeling work.
