no doc, go

I really don’t like it when plans get pushed out of the window. I had my repeat doctor’s appointment in the morning then was going to take pizza or sushi to sis’ place. Got a call that doc is unavailable so the appointment is cancelled. Didn’t feel like traipsing all the way over to sis’. It was almost 11am and I didn’t feel like rummaging through the freezer so I took more clothes for recycling and then a minibus to the halal restaurant for lamb curry noodles.

Windy and cold, the 8km run in the afternoon was done partly against a strong headwind but the low temperatures meant a good pace.

A news article that caught my eye today was google’s AI vs human Go champion. I know the principles of the game go, and my dad played it. I was never very good at games like chess–never good at any games really.

Quite fascinated to watch the devs at google deepmind talk about their AI, called alphago. Clever programming approach. Instead of having the AI go through the

it combines a smaller search tree method with machine learning. The devs first had alphago learn the 30 million moves from games played by human experts then it played thousands of games against itself, to learn new strategies.

Alphago has already beaten the European champion and this week goes up against World champion Lee Sedol for a US$1m prize. So far it’s 2-0. The games are long, game 1 was almost 4hrs and game 2 almost 6hrs.

Some of the biggest advantages of an AI vs human is that the AI never gets tired or emotional. In these areas, humans always lose.
