Ordinal Regression
Caffe Loss Layer for Ordinal Regression with Multiple Output CNN for Age Estimation.
How to
You need to install Caffe first. Copy relative files to Caffe's source code tree.
export CAFFE_HOME=/path/to/caffe
cp layers/ordinal_regression_loss_layer.hpp $CAFFE_HOME/include/caffe/layers/ordinal_regression_loss_layer.hpp
cp layers/ordinal_regression_loss_layer.cpp $CAFFE_HOME/src/caffe/layers/ordinal_regression_loss_layer.cpp
cp layers/ordinal_regression_loss_layer.cu $CAFFE_HOME/src/caffe/layers/ordinal_regression_loss_layer.cu
cp layers/test_ordinal_regression_loss_layer.cpp $CAFFE_HOME/src/caffe/test/test_ordinal_regression_loss_layer.cpp
Modify $CAFFE_HOME/src/caffe/proto/caffe.proto according to layers/caffe.proto
After all, follow Caffe's documents and compile it.
Test the layer
make runtest GTEST_FILTER='OrdinalRegressionLossLayerTest/*'
