Exploring Frontiers of AI at ICLR 2018

IBM Research is a pioneer across many aspects of AI. At the 6th International Conference on Learning Representations (ICLR 2018), our team will share recent discoveries in learning data representations, techniques that are key to the success of machine learning algorithms. These techniques enable machine learning systems to automatically discover how to represent raw data for subsequent analysis. Learning data representations is an important learning task that powers computer vision, speech recognition, natural language processing, drug design, and other advances in AI. At ICLR 2018, IBM Research will present technical papers on adversarial learning, self-organizing networks for multi-task learning, open-domain question answering, disentanglement of representations, reinforcement learning, and deep learning for graphical data. Below are details on the papers IBM Research will be presenting at ICLR 2018.

In one paper, IBM Research will be introducing the concept of a “routing network,” a kind of self-organizing neural network consisting of two components: a router and a set of function blocks. Given an input, the router makes a routing decision, choosing a function block to apply and passing the output back to the router recursively. This allows similar tasks to share layers, while enabling differing tasks to choose distinct layers. Routing networks perform much better than alternative approaches on a set of multi-task learning benchmarks.

Another IBM AI project featured at ICLR 2018 involves a new metric called CLEVER that can be used to evaluate the robustness of a neural network against attack. The CLEVER score calculates the minimum strength that an adversarial attack would need in order to succeed at deceiving the neural network. Higher scores indicate more robust neural networks. The scores are attack-agnostic, meaning they can be applied to existing and unseen attacks, and are computationally feasible for large neural networks. CLEVER scores can be used to compare the robustness of different network designs and training procedures to help researchers build more reliable AI systems.

IBM Research is a gold sponsor of ICLR 18. We will be at the conference expo at booth #500, where you can try your hand at attacking imaginary banks’ AI check image processing systems by distorting check digits and using CLEVER scores to guide your decisions and maximize your profits.
