Reasoning, Attention, Memory (RAM) NIPS Workshop 2015

Organizers: Jason Weston, Antoine Bordes, Sumit Chopra
Duration: one day (see format below)

Motivation and Objective of the Workshop

In order to solve AI, a key component is the use of long term dependencies as well as short term context during inference, i.e., the interplay of reasoning, attention and memory. The machine learning community has had great success in the last decades at solving basic prediction tasks such as text classification, image annotation and speech recognition. However, solutions to deeper reasoning tasks have remained elusive. Until recently, most existing machine learning models have lacked an easy way to read and write to part of a (potentially very large) long-term memory component, and to combine this seamlessly with inference. To combine memory with reasoning, a model must learn how to access it, i.e. to perform *attention* over its memory. Within the last year or so, in part inspired by some earlier works [8, 9, 14, 15, 16, 18, 19], there has been some notable progress in these areas which this workshop addresses. Models developing notions of attention [12, 5, 6, 7, 20, 21] have shown positive results on a number of real-world tasks such as machine translation and image captioning. There has also been a surge in building models of computation which explore differing forms of explicit storage [1, 10, 11, 13, 17]. For example, recently it was shown how to learn a model to sort a small set of numbers [1] as well as a host of other symbolic manipulation tasks. Another promising direction is work employing a large long-term memory for reading comprehension; the capability of somewhat deeper reasoning has been shown on synthetic data [2], and promising results are starting to appear on real data [3,4].

In spite of this resurgence, the research into developing learning algorithms combining these components and the analysis of those algorithms is still in its infancy. The purpose of this workshop is to bring together researchers from diverse backgrounds to exchange ideas which could lead to addressing the various drawbacks associated with such models leading to more interesting models in the quest for moving towards true AI. We thus plan to focus on addressing the following issues:

  • How to decide what to write and what not to write in the memory.
  • How to represent knowledge to be stored in memories.
  • Types of memory (arrays, stacks, or stored within weights of model), when they should be used, and how can they be learnt.
  • How to do fast retrieval of relevant knowledge from memories when the scale is huge.
  • How to build hierarchical memories, e.g. employing multiscale notions of attention.
  • How to build hierarchical reasoning, e.g. via composition of functions.
  • How to incorporate forgetting/compression of information which is not important.
  • How to properly evaluate reasoning models. Which tasks can have a proper coverage and also allow for unambiguous interpretation of systems’ capabilities? Are artificial tasks a convenient way?
  • Can we draw inspiration from how animal or human memories are stored and used?

The workshop will devote most of the time in invited speaker talks, contributed talks and panel discussion. In order to move away from a mini-conference effect we will not have any posters. To encourage interaction a webpage will be employed for realtime updates, also allowing people to post questions before or during the workshop, which will be asked at the end of talks or during the panel, or can be answered online.

Jürgen Schmidhuber, Swiss AI Lab IDSIA
Biography: Since age 15 or so, the main goal of professor Jürgen Schmidhuber (pronounce: You_again Shmidhoobuh) has been to build a self-improving Artificial Intelligence (AI) smarter than himself, then retire. He has pioneered self-improving general problem solvers since 1987, and Deep Learning Neural Networks (NNs) since 1991. The recurrent NNs (RNNs) developed by his research groups at the Swiss AI Lab IDSIA & USI & SUPSI & TU Munich were the first RNNs to win official international contests. They have revolutionized connected handwriting recognition, speech recognition, machine translation, optical character recognition, image caption generation, and are now in use at Google, Microsoft, IBM, Baidu, and many other companies. Founders & staff of DeepMind (sold to Google for over 600M) include 4 former PhD students from his lab. His team’s Deep Learners were the first to win object detection and image segmentation contests, and achieved the world’s first superhuman visual classification results, winning nine international competitions in machine learning & pattern recognition (more than any other team). They also were the first to learn control policies

directly from high-dimensional sensory input using reinforcement learning.

His research group also established the field of mathematically rigorous universal AI and optimal universal problem solvers. His formal theory of creativity & curiosity & fun explains art, science, music, and humor. He also generalized algorithmic information theory and the many-worlds theory of physics, and introduced the concept of Low-Complexity Art, the information age’s extreme form of minimal art. Since 2009 he has been member of the European Academy of Sciences and Arts. He has published 333 peer-reviewed papers, earned seven best paper/best video awards, the 2013 Helmholtz Award of the International Neural Networks Society, and the 2016 IEEE Neural Networks Pioneer Award. He is also president of NNAISENSE, which aims at building the first practical general purpose AI.

Related Workshops

There have been a series of “Learning Semantics” workshops over the last years which touch upon these subjects, but our workshop is more focused, which we hope will generate greater interaction and discussion.
Similarly, there have been a series of deep learning workshops over the years e.g. last year with the title “Deep Learning and Representation Learning”. Deep Learning is very broad and this year is the subject of a symposium. Our workshop focuses on a smaller area that has gained substantial interest (see references above).
