Heterogeneous feature fusion based machine learning on shallow-wide and heterogeneous-sparse industrial dataset

This software is an application of heterogeneous feature fusion based machine learning on shallow-wide and heterogeneous-sparse scientific dataset. The input is a numpy array, containing the images and target values. In this software, a machine learning framework including transfer learning, heterogeneous feature fusion, principal component analysis and gradient boosting is used to solve curse of dimensionality, handle data with missing images, and train predictive models on heterogeneous industrial data. The detailed description about data preprocessing and model can be found in the published paper given below.

Requirements

• Python 3.6.3
• Numpy 1.18.1
• Sklearn 0.20.0
• Keras 2.3.1
• Pickle 4.0
• TensorFlow 2.1.0
• Scipy 1.2.0

Files

1. model_training.py: The script applies the proposed method to train a prediction model on shallow-wide and heterogeneous-sparse scientific dataset. The results will be saved in results.csv file.
2. data folder: This folder has data.pkl, which is the example dataset, because Toyota dataset is not public available due to confidential reasons.

How to run it

1. Run commend below, which uses proposed method to train the model and save results in results.csv file.

   python model_training.py
