Major publicly visible milestone for Artificial Intelligence – tree searching, learning by playing itself Gerald Tesauro (1994) developed a self-teaching backgammon program called TD-Gammon. Learning its strategy almost entirely from self-play, TD-Gammon achieved a human world-champion level of performance. On May 11, 1997, IBM’s Deep Blue beat the world chess champion Garry Kasparov in a six-game match: Two wins for Deep Blue, One for Kasparov and Three draws. AlphaGo is a computer program developed by Google DeepMind in London to play the board game Go.[1] In October 2015, it became the first Computer Go program to beat a professional human Go player without handicaps on a full-sized 19×19 board.[2][3] In March 2016, it beat Lee Sedol in a five-game match, the first time a computer Go program has beaten a 9-dan professional without handicaps.[4] Although it lost to Lee Sedol in the fourth game, Lee resigned the final game, giving a final score of 4 games to 1 in favour of AlphaGo. In recognition of beating Lee Sedol, AlphaGo was awarded an honorary 9-dan by the Korea Baduk Association.

For example, automatic argument construction could serve to dramatically enhance business processes and decision making – whether by providing assisted reasoning for which treatment will work best on a patient, or by helping salespeople develop persuasive arguments when working with clients in deal negotiations, or by presenting pro and con arguments in support of or against government policies.

  • #40 Six years ago, IBM and our university partners embarked on a quest—to build a brain-inspired machine—that at the time appeared impossible. Today, in an article published in Science, we deliver on the DARPA SyNAPSE metric of a one million neuron brain-inspired processor. The chip consumes merely 70 milliwatts, and is capable of 46 billion synaptic operations per second, per watt–literally a synaptic supercomputer in your palm. Along the we have journeyed from neuroscience to supercomputing, to a new computer architecture, to a new programming language, to algorithms, applications, and now to a new chip—TrueNorth. Considering overall energy consumption underscores the divergence between the brain and today’s computers even more starkly. Note that a “human-scale” simulation with 100 trillion synapses (with relatively simple models of neurons and synapses) required 96 Blue Gene/Q racks of the Lawrence Livermore National Lab Sequoia supercomputer—and, yet, the simulation ran 1,500 times slower than real-time. A hypothetical computer to run this simulation in real-time would require 12GW, whereas the human brain consumes merely 20W. To support these algorithms at ever increasing scale, TrueNorth chips can be seamlessly tiled to create vast, scalable neuromorphic systems. In fact, we have already built systems with 16 million neurons and 4 billion synapses. Our sights are now set high on the ambitious goal of integrating 4,096 chips in a single rack with 4 billion neurons and 1 trillion synapses while consuming ~4kW of power.
  • #42 Technology support is a labor-intensive business – both diagnosis and field repair. There is a large body of prior incident reports and service requests – similar symptoms might have different root causes – server down due to full file system or hardware error There are many resolution reports and success indicators Diagnosis often conducted iteratively in a dialog, pruning potential causes to the most likely ones Knowledge Extraction and Representation: Enhance Knowledge Base (with domain vocabulary, instances, constraints and rules) to help current way of working (for Explicit, e.g. dialogue and NLC). The input to KB should be from domain experts, input from humans and historical data Dialog: Implicit: Create an ontology/representation to create coarse representation of concepts in the space together with tasks Inferred: Need recorded dialogues and once we have that we can use learning techniques to estimate what happens next in the hardcoded dialogues/automations. This is used to build the ontology
