Artificial Intelligence - Yorick Wilks ****

Artificial intelligence is one of those topics where it's very easy to spin off into speculation, whether it's about machine conciousness or AI taking over the world (and don't get me onto the relatively rare connection to robots - cover designer please note). All the experience of AI to date has been that it has been made feasible far slower than originally predicted, and that it faces dramatic limitations. So, for example, self-driving cars may be okay in limited circumstances, but are nowhere near ready for the commute home. Similarly, despite all the moves forward in AI technology, computers are so-so at recognising objects after learning from thousands of examples - sometimes fooled by apparently trivial surface patterning - where humans can recognise items from a handful of examples.

Even so, we can't deny that AI is having an influence on our lives and Yorick Wilks, emeritus professor of AI at the University of Sheffield, is ideally placed to give us a picture of how our current AI technology was developed, what is possible now and what may come in the future, in a compact introduction to a very important field.

Although many of the familiar basics are here, Wilks also gives us some novel considerations, whether it is the relationship of web searching to AI, what the guts of an AI program is like, or the field of AI companions for humans (no, probably not robots), which Wilks believes will be very significant in the future. He also works through the doom-mongering from some commentators, showing that while there are areas that we need to be seriously concerned about - such as the influence of algorithms we don't understand - many of the bugbears of AI are likely not to be real issues.

As Wilks points out in his summary, though AI has had some impressive successes, it is still nowhere near the goal of producing a form of general intelligence, and seems unlikely to do so - for a machine to be good at, for example, playing a game such as chess, Jeopardy or Go does not require true intelligence. But there is no doubt of the importance of AI and Wilks gives us a very distinctive and thought-provoking look at this burgeoning field.

The Laws of Thought - Tom Griffiths *****

In giving us a history of attempts to explain our thinking abilities, Tom Griffiths demonstrates an excellent ability to pitch information just right for the informed general reader. We begin with Aristotelian logic and the way Boole and others transformed it into a kind of arithmetic before a first introduction of computing and theories of language. Griffiths covers a surprising amount of ground - we don't just get, for instance, the obvious figures of Turing, von Neumann and Shannon, but the interaction between the computing pioneers and those concerned with trying to understand the way we think - for example in the work of Jerome Bruner, of whom I confess I'd never heard. This would prove to be the case with a whole host of people who have made interesting contributions to the understanding of human thought processes. Sometimes their theories were contradictory - this isn't an easy field to successfully observe - but always they were interesting. But for me, at least, ...

The AI Paradox - Virginia Dignum ****

This is a really important book in the way that Virginia Dignum highlights various ways we can misunderstand AI and its abilities using a series of paradoxes. However, I need to say up front that I'm giving it four stars for the ideas: unfortunately the writing is not great. It reads more like a government report than anything vaguely readable - it really should have co-authored with a professional writer to make it accessible. Even so, I'm recommending it: like some government reports it's significant enough to make it necessary to wade through the bureaucrat speak. Why paradoxes? Dignum identifies two ways we can think about paradoxes (oddly I wrote about paradoxes recently , but with three definitions): a logical paradox such as 'this statement is false', or a paradoxical truth such as 'less is more' - the second of which seems a better to fit to the use here. We are then presented with eight paradoxes, each of which gives some insights into aspects of t...

Einstein's Fridge - Paul Sen ****

In Einstein's Fridge (interesting factoid: this is at least the third popular science book to be named after Einstein's not particularly exciting refrigerator), Paul Sen has taken on a scary challenge. As Jim Al-Khalili made clear in his excellent The World According to Physics , our physical understanding of reality rests on three pillars: relativity, quantum theory and thermodynamics. But there is no doubt that the third of these, the topic of Sen's book, is a hard sell. While it's true that these are the three pillars of physics, from the point of view of making interesting popular science, the first two might be considered pillars of gold and platinum, while the third is a pillar of salt. Relativity and quantum theory are very much of the twentieth century. They are exciting and sometimes downright weird and wonderful. Thermodynamics, by contrast, has a very Victorian feel and, well, is uninspiring. Luckily, though, thermodynamics is important enough, lying behind ...
