| | JUNE 20238CIOReviewIN MY OPINIONAI has been with us since the 1950's but it has always been a bit underwhelming. Yes there were some pretty impressive games of chess played against human champions by IBM's Deep Blue in the late 90's, then IBM's Watson won at the game of Jeopardy in 2011, and then Google's AI beat a grand master at Go in 2016. All of these were impressive in the sense of moving the boundary of what we thought AI was, but they were all specific to one game or one application even if that application was a complex one. Recently however AI seems to have exploded onto the scene with ChatGPT and Bard showing just how good and how "general" AI can get, and these large language driven applications seem to have surprised everyone. We really should not have been surprised if we had been paying attention. What impressed me in recent years was, in 2021, when Beethoven's unfinished Tenth Symphony was completed by AI, and then in 2022 when AI accurately predicted gene expressions in a type of yeast. That last neural network predicted the effectiveness and evolution of gene promoter sequences, something which until then was an amazingly complex computational task. AI has been quietly "generating" art, music, speeches and images for some time. What just happened is that it got a whole lot better.By now, everyone has probably had a play with one of the latest AI tools based on large language models or the image based equivalent. Initially, it seems uncannily like magic. You can ask for speeches, poems, songs "in the style of..", or art "in the style of..". There is enough information out there to train these models that they can do a pretty good job of generating a jazz song in the style of Miles Davis. The trick is to ensure the original artist is not left out. If their work is used as input, they should get credit and possibly royalties depending on how the derived art is used. After a while, however, you do start to see some serious limitations, even some "hallucinations" from these tools. I recently asked ChatGPT to write a speech in the style of me. What it generated was pretty ordinary in my view ­ lacking real substance and overall, somewhat bland. When I passed the speech to my wife, her response was "yep, that's you alright". I was even more disappointed! What it showed (at least in my opinion) was that, while the tool did a great job of finding, connecting and synthesising source material, what it lacked was real "judgement" of the important issues and the context of such a speech. Of course, what you can do is keep adding context by providing additional input. You can refine and refine until it does largely hit the mark. This is apparently how the Beethoven symphony was completed. It is a bit like conducting with your keyboard, or even your voice. In that sense, the tools can be used as the assistant or co-pilot as we see more and more with By Ian Oppermann, Chief Data Scientist, NSW Department of Customer ServiceAI ... WHAT JUST HAPPENED?
