Session Goal: The session aimed to implement a Random Forest Regressor using scikit-learn in Python and address data cleaning issues in a property dataset.
Key Activities:
- Implemented a Random Forest Regressor in Python using scikit-learn, focusing on data loading, preprocessing, model fitting, and making predictions.
- Fixed DataFrame modification warnings by creating copies of data and handling missing values, specifically computing the price per square meter.
- Investigated and cleaned NaN values in the dataset, ensuring accurate computation of
price_m2
values. - Validated and converted data types in the
price_m2
column to ensure they contain valid numeric values. - Addressed KeyError in label encoding by updating the LabelEncoder with new labels found in the test data.
Achievements:
- Successfully implemented a Random Forest Regressor and resolved data cleaning issues, improving the datasetβs integrity for analysis.
- Ensured the robustness of the data preprocessing pipeline by handling potential errors and warnings.
Pending Tasks:
- Further testing and validation of the Random Forest modelβs performance on the cleaned dataset.
- Documentation of the data preprocessing steps and model implementation for future reference.
