Jadon contributed to the Insight-Sogang-Univ/insight-13th repository by developing seven end-to-end machine learning and NLP features over one month. He built an employee attrition prediction model, collaborative filtering recommendation systems, and market basket analysis pipelines, applying algorithms such as CatBoost, LightGBM, and XGBoost. His work included deep learning with PyTorch on the MNIST dataset and comprehensive NLP workflows using BERT, GPT, and LangChain for sentiment analysis and text generation. Jadon focused on rigorous data preprocessing, feature extraction, and hyperparameter tuning, delivering well-documented Jupyter Notebooks in Python and SQL that demonstrated depth across the ML and data science stack.

May 1, 20252025-05 monthly summary for Insight-Sogang-Univ/insight-13th: Focused on delivering business-value features and rigorous ML/NLP experiments across the ML stack, with notebooks and artifacts prepared for evaluation and potential productionization. Key features delivered include an Employee Attrition Prediction Model with end-to-end data loading, preprocessing, multiple algorithm experiments, and hyperparameter tuning to maximize accuracy; a Collaborative Filtering System (item-based and user-based) for recommendations; Market Basket Analysis using Apriori and FP-Growth to uncover cross-sell opportunities; MNIST MLP Deep Learning Notebook implemented in PyTorch for loading, training, and evaluation; NLP pipelines covering Text Preprocessing with TF-IDF and Word2Vec; and a Comprehensive NLP workflow with BERT and GPT (LangChain/RAG) for sentiment analysis and example text generation. No explicit bug fixes are documented this month; the focus was on feature delivery, experimentation, and demonstrable outcomes across data science and ML tooling.
