The Dual Information Bottleneck

A new framework, which resolves some of the known drawbacks of the Information Bottleneck. We provide a theoretical analysis of the framework, finding the structure of its solutions and present a novel variational formulation for DNNs.

Information in Infinite Ensembles of Infinitely-Wide Neural Networks

Study the generalization properties of infinite ensembles of infinitely-wide neural networks. We report analytical and empirical investigations in the search for signals that correlate with generalization.

Neural Correlates of Learning Pure Tones or Natural Sounds in the Auditory Cortex

Analysing perceptual learning of pure tones in the auditory cortex. Using a novel computational model, we show that overrepresentation of the learned tones does not improve along the training.

Attentioned Convolutional LSTM Inpaintingv Network for Anomaly Detection in Videos

A semi supervised model for detecting anomalies in videos inspiredby the Video Pixel Network. We extend the Convolutional LSTM video encoder of the VPN with a novel convolutional based attention. This approach could be a component in applications requiring visual common sense.

Sequence Modeling Using a Memory Controller Extension for LSTM

We extend the standard LSTM architecture by augmenting it with an additional gate which produces a memory control vector signal. This vector is fed back to the LSTM instead of the original output prediction. By decoupling the LSTM prediction from its role as a memory controller we allow each output to specialize in its own task.

Opening the Black Box of Deep Neural Networks via Information

We demonstrate the effectiveness of the Information-Plane visualization of DNNs. (i) Most of the training epochs are spent on compression of the input to efficient representation. (ii) The representation compression phase begins when the SGD steps change from a fast drift into a stochastic relaxation (iii) The converged layers lie very close to the information bottleneck theoretical bound, and the maps to the hidden layers satisfy the IB self-consistent equations (iv) The training time is dramatically reduced when adding more hidden layers.

Automated Testing of Graphics Units by Deep-Learning Detection of Visual Anomalies

A deep-learning based system, which performs real-time detection of diverse visual corruptions in videos. Developing this system involved challenging data science aspects to enable detection of small distortions with low false alert rates.
