To developed practical knowledge and hands on experience in Machine Learning and Natural Language Processing (NLP), with strong focus on phyton as the core programming language. My work includes data preprocessing, feature engineering, model training and evaluation using popular libraries such as Scikit learn, TensorFlow, Keras, NLTK, SpaCy and pandas. In the field of NLP, I have worked on text classification, sentiment analysis, named entity recognition (NER), topic modeling and keyword extraction from large text datasets. I am proficient in using techniques such as TF-IDF, Word2Vec, BERT and LSTM-based models to analyze and interpret human language data. Additionally, I have explored the application of machine learning models in domain such as :
-Predictive Maintenance
-Customer Feedback Analysis
-Anomaly Detection
-Recommendation Systems
-Ouality Assurance Report Analysis
My approach combines data-driven problem solving with algorithmic thinking, enabling me to contribute effectively to AI- powered solutions. I also keep up with emerging trends in ML and AI to continuously enhance my capabilities.
