FacialExpressionRecognition

This is my implementation of a Convolutional Neural Network for Facial Expression Recognition.

I used the fer2013 dataset on Kaggle. The model has an accuracy of ~68% on the test set before using the averaging method and ~69% after applying the averaging method.

Due to limited time, I did not create an emsemble. An emsemble of multiple trained models using different initialization might improve the result a bit more.

To train the model using GPU run THEANO_FLAGS=mode=FAST_RUN,device=gpu,floatX=float32 python cnnmodel.py

To test the accuracy after averaging run THEANO_FLAGS=mode=FAST_RUN,device=gpu,floatX=float32 python averagingmethod.py

Different packages need to be installed. You can also used pre-installed Keras and Theano AMI on Amazon Web Services. Imutils, OpenCV can be installed by pip and conda. They are used for the averaging method.

I used C++ library Dlib for face detection.

I used several ideas in these papers to create my model:
