crazy-sensei.com can analyze your games

[Monadology]

Is there any chance that some of these analysis tools (like the Policy view and the red 'error' bars) might be added to the PC version of Crazy Stone Deep Learning? The visuals make reviewing a lot easier, and it would be a shame if the $80 pricetag for CS:DL is for something that is worse for game review than this online service.

Hi Rémi, I'm really liking this tool, a nice UI that works well on mobile too . I have a question about the meaning of the policy view red squares. Is it how popular that move is in the policy network, irrespective of winning probability after playing it? If you look in this game at move 15, for the next move white (Haylee) played the 2-4 point in the corner which is a very normal move in pro games, and it looks like it has the biggest policy red square. However, that move has a medium-size red error bar, indicating it was a mistake (according to CS) and raised black's winning chances. On the 'tree' view it is #2, and #1 is the 2-space pincer (which has significantly smaller red policy square). Does that mean the pincer was the best move for win probability, with the corner move 2nd? This does actually tally with some other bot analysis I heard about (maybe AlphaGo, or Zen or CS, I can't recall) that it didn't like that corner defence.

I am afraid that the awareness about the value of analysing tools is greater in the West (e.g. Rémi) than in the East (e.g. Unbalance).

In my opinion, it should not be underestimated that the analysing tools of a programme (e.g. CS DL) will also benefit players of a strength (far) above the programme's playing strength.

I let Crazy Sensei analyse one of the recent AlphaGo games (vs. Meng Tailing, #9). It seems to me that the result (winning probability) is totally congruent with CS DL's "P B(wins)".

But with Crazy Sensei, you have additional views, and the histograms are also stored for browsing through.

Whenever you have time to do a few UI/UX tweaks:
- There is no way to know the current move number.
- Keyboard shortcuts (at least left/right to go over the game) would be nice.

- There is no easy way to know the current move number.

My current workaround:
- right-click on current vertical bar in the win% graph
- Inspect element (in dev tools / firebug etc)
- find value of 'data-title' attribute

It did not work for me. When I tried to upload a game, it always says that I have no credit. Have I missed anything?

What does it say if you to to your account page? 0 credit? If so it's 'working' as expected, not all users got free credit.

Thanks for your feedback.

I'll write a detailed explanation of the analysis data on the site. The "policy" output is the output of the neural network. It is an heuristic that guides the search, but the search may eventually change the move order, based on the outcome of playouts. This is why the move order does not necessarily matches the policy.

We now display the move number, and also change the URL each time the move number changes. So you can get a link to a particular move in the game if you wish to bookmark or share it.

Some users did not receive any email from the server. That's because our IP was given a bad reputation by Symantec, and also my MX DNS record was not very properly set. I fixed this yesterday, and it seems that everybody is receiving emails now. If you wish to try to register again with the same email address that failed in the past, please use the "forgot password" procedure. If you still don't receive emails, then please tell me.

We gave free credit only to the first 100 users or so. We'll give more later, to test the next version.

For uploading games, crazy sensei will only accept 19x19 games, right?
Sorry if this is a silly question.

It is not silly at all. Right now, it only accepts 19x19. But 13x13 and 9x9 will be supported in the future.
