Raw

Distracted Driving Final Project

This repo is is dedicated to keeping all of the research and analysis related to the final project in my applied statistics masters program at Texas A&M. The data in this project are of 8 driving simulations for 66 individuals ranging from 3,000 to 30,000 observations per simulation. There are over 6.7 million observations in the entire dataset. The data from each simulation includes likelihood scores for 8 facial expressions recorded at a fixed interval of .03 seconds. Stimuli data which records targetted events that were introduced into each simulation and basic demographic data on each subject are also available.

Steps to reproducing my work:

The data accompanying this project are too large to host on github. I have created some Python and R scripts for extracting the raw data and combining them for analysis. Since the data are too large you will need to store the data locally and in specific locations to reproduce my results.

Required Software

  • Python (Anaconda 2.7 recommended, pandas package required)
  • R (RStudio Recommended for running .Rmd files)

Extract and Process Raw Data

  • Execute python extract_faces.py from the Files/ folder.
  • Execute python extract_stimuli.py from the Files/ folder.
  • The py scripts should produce 2 files in Files/ (data-faces.csv, data-stimuli.csv).
  • Run 01_data_prep.R, combines and cleans the 3 data files (/Files/Other/data-demographics.csv is the 3rd file)
  • Run 03_data_setup.R, creates centered and summary level datasets
  • Run 06_data_mdl_setup, creates training/testing sets

Reproduce my models

  • Run 07_model_nnet_best_model.R, builds my final model
  • Run 07_model_nnet.R, builds model objects saved to R-Models

Reproduce my written analysis (produces .pdf reports)

  • 02_processing_and_exploration.Rmd, data processing and corrections
  • 04_propasal.Rmd, initial analysis proposal
  • 05_initial_modeling.Rmd, first pass models on summarised data
  • 07_modeling_nnet.Rmd, feed forward neural net models on raw data
  • 09_Project_Outline.Rmd, summary of all work
