- Competency 8.2
Competency 8.2: Build and evaluate models using alternative feature spaces.
I used the different feature spaces that I saved in the previous exercise for building models. My data set was very small and I intended to use it just for testing. I found significant improvement in metrics while comparing the models of POS features Vs Unigrams ...
