This software provides the code for an iterative machine learning framework that uses extremely randomized trees (also known as extreme random forests) for predicting temperature profiles in an additive manufacturing process.

Requirements:

• Scikit-Learn 0.19.1
• Numpy 1.14
• Pandas 0.22
• XGBoost 0.7 or higher

• additive_util.py: Core utility file for this repository (including incorporating neighbor information)

• predict_cube.ipynb
• predict_date_cube.ipynb
• predict_cube_iterative.ipynb

The prepared dataset is available at https://www.dropbox.com/s/cbwyhy18ofw0t7j/data.zip?dl=0
