IBM Research at IJCAI: Pushing new AI frontiers from Down Under

For the first time in 26 years, Australia is hosting the globally revered International Joint Conference for Artificial Intelligence (IJCAI). The greatest minds in artificial intelligence (AI) from across the globe will descend on Melbourne next week to present the latest advancements in training machines to learn, reason and interact in a natural, human-like way.  It is a highly competitive conference with only 26 percent of papers accepted in 2017. This year, IBM is presenting 13 papers representing the latest research on the topic.

But before jumping into what’s happening at the next frontier of AI, let’s look at where this all started. IJCAI itself was first held in 1969, which IBM also presented at, and if you look at the proceedings, it focused on exploring the earliest milestones of areas we still investigate today – natural language analysis, pattern recognition, and machine learning. In fact, the idea of AI stems back further with the notion of creating a system which amplifies people’s own knowledge and understanding, which was presented in an essay by Vannevar Bush in 1945. Whilst today AI conjures thoughts of supercomputer intelligence systems and robots changing the world and our lives, my research peers and I know full well that the reality of AI must be taken back to that first concept of human and machine working together – augmented intelligence, if you will.

Today, some of these ideas are well and truly on our doorstep. We have taught machines to read, to see, to hear, to speak, to interact and to learn like humans do. It is an industry predicted to be worth more than $47 billion by 2020. And we’re just at the start. Next year, Gartner predicts that 30 percent of our interactions with technology will be through conversations with smart machines. IBM Research is at the forefront of building the underlying core AI technologies needed to power AI systems – as evidenced by our recent performance breakthrough and paper on distributed deep learning software, which will make it easier for enterprises to utilize machine learning and AI in a time efficient and simple manner.

So what’s happening at IJCAI to be excited about?

Below is a snapshot of IBM’s activities with a special look at two important papers:

Papers

Improving classification accuracy of deep neural networks for spiking neuromorphic chips

Antonio Jose Jimeno Yepes, Jianbin Tang, Benjamin Mashford

New learning algorithms based on deep learning match human performance, e.g. at image classification tasks and in playing strategy games. On the other hand, these new complex algorithms run on very power hungry computer architectures that prevent them from being used outside of computing clusters, thus they are not available in wearable devices (e.g. in your mobile phone) or autonomous systems. The team used a brain-inspired spiking neuromorphic computing architecture consuming power in the order of milliwatts (in comparison to hundreds or thousands of watts of traditional systems) that supports real-time processing of streaming data.  The IBM team has developed a new learning algorithm that learns a deep neural network configuration compatible with the chip and overcomes some of the shortcomings of previous algorithms. Our algorithm shows a low power solution with state-of-the- art classification performance in electroencephalogram data and the MNIST handwritten data set, which is relevant to wearable devices and autonomous systems. We think there is no better way to showcase the impact of an idea than by demoing it live, so we integrated the chip with a humanoid NAO robot by Softbank and gave it the ability to recognize objects in real-time using deep learning technology. Come to the IBM exhibitor booth and take part in our interactive demo.

Learning Feature Engineering for Classification

Fatemeh Nargesian, Horst Samulowitz, Udayan Khurana, Elias Khalil, Deepak Turaga

The Learning Feature Engineering technique removes the “hunch” in predictive modelling by automating the core task of feature engineering. It helps a data scientist reduce the time and effort required in analyses, and is poised to make data science easier and better. A team of IBM scientists has developed a novel meta-learning technique, which means learning to perform machine learning. Listen in to the talk we will deliver and learn more about this breakthrough in putting the ‘machine’ in machine learning.

Stay tuned for a more detailed blog on this innovation next week.
