Question: What a property will sell for Sample data: Real Estate Valuation (UCI) Attribution: Yeh, I. (2018). Real Estate Valuation [Dataset]. UCI Machine Learning Repository. https://doi.org/10.24432/C5J30W. CC BY 4.0. Modified: split into training and held-out rows, predictions added. Predicts: house price of unit area (Regression) Result Its predictive value is STRONG, measured on held-out rows that took no part in choosing it. Certification: CERTIFIED — AUDITABLE & REPEATABLE PREDICTIVE MODEL Value verified: yes. The winning model demonstrated strong predictive value over the baseline on holdout rows that took no part in choosing it. Winner: Random Forest, best of 12 models built Trained on: 311 rows Certificate figures: the holdout half of the blind rows, 52 rows that took no part in choosing the winner Error reduction: 55.3% (90% range 43.2-66.2%) Mean absolute error: 5.783 vs 12.95 for the baseline Baseline: always predict the training median (38.1) Compare figures: all 103 blind rows, including the half the winner was chosen on R2: 0.6583 MAE / RMSE: 4.96 / 9.21 Within 10%: 53 of 103 The predictions file 103 held-out rows, one per line: heldout_row, X1 transaction date, X2 house age, X3 distance to the nearest MRT station, X4 number of convenience stores, actual_Y house price of unit area, predicted_Y house price of unit area. heldout_row numbers the held-out rows 1 to N in the order the product tested them. It is not a row number from the original dataset: the split shuffled the rows. Columns left out of this download: X5 latitude, X6 longitude.
