Content

• DANN.py contains the learning algorithm. The fit() function is a very straightforward implementation of Algorithm 1 of the paper.

• experiments_amazon.py contains an example of execution on the Amazon sentiment analysis dataset (a copy of the dataset files is contained in the folder data). Computes the target test risk (see Table 1 of the paper) and the Proxy-A-Distance (see Figure 3 of the paper).

• experiments_moons.py contains the code used to produce Figure 2 of the paper (experiments on the inter-twinning moons toy problem).

• mSDA.py contains the functions used to generate the mSDA representations (these are literal translations of Chen et al. (2012) Matlab code)
