The talk will cover some of the most recent groundbreaking work realized at Clarifai in the domain of neural networks and interpretability.

Deep neural networks are defining the state of the art in many tasks, such as detection and visual question answering, however often it is unclear what makes them arrive at a decision for one given input sample, e.g. one image. Notably, for the existing methods of explanations, there are large unclarities about what they really explain, e.g. what information backpropagation really does provide. In this talk I am going to present layer-wise relevance propagation, an approach to decompose the prediction of a deep neural network for one image in terms of single pixels and regions. Theoretical motivations, explanations of differences versus deconvolution and backpropagation will be given. I will introduce a framework to evaluate the computed explanations based on the implied ordering of regions and pixels. You will see results of numerical evaluations of the computed visualizations on Imagenet, MIT Places and SUN397 test data. Finally its ability to identify biases in your training data will be shown.

Human societies in the digital age have abruptly become data rich. We are still in the very early stages of making those data manageable by transforming them into information and so are we in the process of making that information useful and usable in different domains in the form of actionable knowledge. Data modelling thus becomes a stepping stone in this process, something that statisticians, for instance, know only too well. Modern computational intelligence and machine learning are playing an increasingly important role in knowledge extraction in many practical and scientific applications. In this brief introductory talk on the topic of model interpretability, I will use biomedical applications as a perfect example of the many challenges still facing experts in the process of making complex models acceptable in real-world problems.

Brain imaging by PET, MR, EEG, and MEG has become a cornerstone in systems level neuroscience. Statistical analyses of neuroimage datasets face many interesting challenges including non-linearity and multi-scale spatial and temporal dynamics. The objectives of neuroimaging are dual: We are interested in the most accurate, i.e., predictive, statistical model, but equally important is model interpretation and visualization which often takes the form of brain maps. I will introduce some current machine learning strategies invoked for explorative and hypothesis driven neuroimage modeling, and present a framework aimed at model selection, evaluation, and interpretation based on computer intensive data re-sampling. Within the framework we obtain both an unbiased estimate of the predictive performance and of the reliability of the brain map visualization.
