This webpage aims to regroup publications and software produced as part of a joint project at Fraunhofer HHI, TU Berlin and SUTD Singapore on developing new method to understand nonlinear predictions of state-of-the-art machine learning models.

Machine learning models are usually characterized by very high predictive power, but in many case, are not easily interpretable by a human. Interpreting a nonlinear classifier is important to gain trust into the prediction, and to identify potential data selection biases or artefacts.

The project studies in particular techniques to decompose the prediction in terms of contributions of individual input variables such that the produced decomposition (i.e. explanation) can be visualized in the same way as the input data. These visualizations are called "heatmaps".

A heatmap is a visualization of an input example (e.g. image) that highlights which features a trained machine learning model (e.g. a deep neural network) considers important to achieve a classification decision. An example for an image classified as "matches" by the GoogleNet neural network is shown here:

Check out our heatmap gallery for more examples. Heatmaps can also be produced for text, or scientific data such as EEG.

Draw a handwritten digit and see the heatmap being formed in real-time. Create your own heatmap for natural images or text.
