The dataset provided 9 features that I used to try to predict the median housing data.  I performed expanded exploratory data analysis in order to consider the best ways to encode categorical data and scale the numeric features.  I also used PCA to add features, as well as K-means clustering to identify potential meaningful cluster identifiers.  THis informaiton was fed into several regression models/estimators, all of which were then run through gridsearch and cross validation to determine the best model on split training and validation data.  \n\n## Results\n### Model Selected \u0026 Scoring\nOf the models considered, the best was was a **Gradient Boosted Decision Tree with max depth set to 8** (with default parameters otherwise [e.g., learning rate = 0.1]).  The score on validation data was **~0.84**, which is a respectable score but there is likely room for improvement.  It scored well on the training data (0.95), so it is unlikely that the model is overfitting.\n\n## Skills (Developed \u0026 Applied)\nProgramming, Python, Statistics, Numpy, Pandas, Matplotlib, Scikit-learn, Dataframes, Data Modeling, EDA, Data Visualization, Data Reporting, Classification, Supervised ML, Cross Validation, Grid search, Unsupervised ML, PCA, Seaborn, Folium\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdmarks84%2Find_project_california-housing-data--kaggle","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdmarks84%2Find_project_california-housing-data--kaggle","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdmarks84%2Find_project_california-housing-data--kaggle/lists"}
