Project 3
Linear Regression

The project aimed to analyze the relationship between various housing market variables and construct a multiple linear regression model. This model forecasts the median house value based on key predictors such as the 'lm' (lower status of the population) and 'lstat' (percentage of lower status of the population) variables.

Data Visualization
Natural Language Processing

I possess a strong background in Natural Language Processing (NLP), as evidenced by my extensive work with SpaCy, a leading NLP library in Python. My expertise includes performing tokenization, part-of-speech tagging, and named entity recognition (NER). I have effectively utilized SpaCy's pre-trained models to analyze complex garden path sentences, which are designed to challenge linguistic parsing systems.

This project highlighted the capabilities and limitations of current NLP models, showing both correct identifications, like Mississippi as a geopolitical entity, and misclassifications, like Band-Aid as an organization. My work involved also a critical analysis of the outcomes, providing insights into the performance of NLP tools. This hands-on experience, combined with my knowledge of various NLP tasks and tools, underscores my profound understanding and capability in the field of NLP.
