Averaging this training data for the move across 50 games should cause P to move towards 16.3%
I think this is probably good enough. As it moves towards 16.3% it will accelerate and move up even faster.
Also generally I think we should not do any of these sort of changes that try to improve on the paper until after we fix things that are probably wrong such as rule50.

As it moves towards 16.3% it will accelerate and move up even faster.
Yes, in fact from all the runs, once the prior for this particular move reaches P: 1.28%, it'll start driving at least 100 visits of 800 towards it. Similarly, once it gets to P: 2.25%, over 700 visits will go to it for near 90% average tactic training. I.e., networks are not in a virtuous cycle of self-learning for this tactic yet.
However, if you look at the data showing the priors for this move across the various network ids, the prior has stayed around 0.3%. And from that same data, it shows that nearly all those networks would have put over 700 visits into the move if only search initially had 2 visits to it.
That means even with the current "16.3% average tactic training," there is way more training data that drives the prior towards 0.3% instead of higher. This means across 250 network generations, the existing "16.3%" noise has been unable to get it to learn this tactic when 2 visits would have.
The new network prior approaches ((16.3% * number of similar board state) + (0% * other board states)) / total board states
. If someone has any suggestions to how to measure the number of these learnable board states, that would be great. (Although, I doubt we would do anything proactively to try to increase that number of similar board states, but we might do something to increase the 16.3%.)
from lc0.
@ASilver requested running with 3.1 PUCT, and I see that the latest lc0 master 2321011 uses that and gets 24.9%. The earlier runs were against then-next 5054269 with 16.3% average tactic training.
Here's a graph of testing various PUCT at noised root:

Here's the "average tactic training" for various engine configurations and board states:
config | SCTR/359 | 359/Wasp | 351/EXch | 351/Hakk | iCE/351 | 351/Bobc |
---|---|---|---|---|---|---|
root PUCT 1.2 | 19.9% | 12.7% | 38.9% | 57.6% | 32.8% | 40.4% |
default | 24.9% | 18.8% | 28.6% | 63.3% | 42.7% | 44.3% |
ε 0.5 | 31.5% | 38.1% | 49.1% | 56.9% | 46.7% | 51.0% |
α 3.0 | 52.8% | 35.4% | 77.2% | 75.1% | 71.7% | 78.3% |
ε 0.5, α 3.0 | 69.9% | 65.0% | 88.8% | 77.4% | 79.4% | 74.6% |
twice | 86.0% | 13.0% | 87.3% | 74.2% | 83.5% | 81.5% |
These are all tested with current master 2321011 where default is PUCT 3.1, α 0.3, ε 0.25, no twice visits. The patches for root PUCT and twice visits are in earlier comments, and noise changes are just changing ApplyDirichletNoise(node, 0.25, 0.3)
call.
I used the networks listed (id351 or id359) as notably, the latest id369 has learned the tactic from the Hakkapeliitta game where with PUCT 1.2 (lczero 0.6), an average tactic training of 57.6% was enough to learn it.
Here's the priors for each of the expected moves:
game | old prior | id369 prior |
---|---|---|
SCTR | 0.33% | 0.43% |
Wasp | 0.23% | 0.19% |
EXchess | 0.03% | 0.02% |
Hakkapeliitta | 0.32% | 50.61% |
iCE | 0.08% | 0.12% |
Bobcat | 0.14% | 0.32% |
So looks like noise is indeed working, and with PUCT change to 3.1, there'll be less of a need to do additional changes to improve training tactics.
from lc0.
I analyzed all the CCLS id359 games to find low prior moves that were played to see if the same network would have found it with noise. Here's a first set that the other AI played that the network didn't really considered at all. Not all have major swings in win rate or even change the outcome, but at least this first one against Houdini, lczero thought it was 63% win rate but after the 0.15% prior move, it's actually the opponent with 75% win rate.
For each unexpected played move, a screenshot and uci position and what id359 thought of it and the top alternate moves when forced to explore at least 10 visits of 800:

And same analysis as before with 50 noised games from the above board states to calculate the average training:
config | Houdini | Naum | Scorpio | Protector | Vajolet | Cheng |
---|---|---|---|---|---|---|
root PUCT 1.2 | 6.8% | 2.2% | 4.5% | 1.3% | 0.3% | 19.9% |
default | 8.2% | 21.3% | 20.1% | 0.6% | 4.7% | 15.8% |
ε 0.5 | 19.6% | 36.5% | 23.2% | 4.8% | 9.5% | 33.5% |
α 3.0 | 1.3% | 17.2% | 26.5% | 0.3% | 0.3% | 38.0% |
ε 0.5, α 3.0 | 10.0% | 53.4% | 57.6% | 1.0% | 5.2% | 55.5% |
twice | 7.6% | 10.5% | 57.0% | 2.8% | 1.9% | 32.2% |
- PUCT 1.2 generally seems bad for search visiting these very low prior moves to try to increase training
- A higher epsilon (with default 0.3 alpha) allows a spike in prior to allow deeper exploration of a given move, which seems to be needed to play out the Houdini game's sequence of 8 captures / checks
- A higher alpha results in a flatter noise just generally allowing all moves to be explored, and along with a higher epsilon helps reduce any strongly biased existing priors
- Twice visits is similar to the flat noise except it ensures search gets an eval after a potential forced followup move
from lc0.
I rebased @ASilver's params from #46 onto 2321011 where I did the tests from earlier. Analyzing the same 12 games from earlier with the same networks each with 50 runs of noise, the average training does go up quite a bit. This is most likely from softmax, as it increases the policy quite a bit in each of these cases, where the usual priors are much lower. I've included the training numbers and move prior for default and with the adjusted params:
game | default training | adjusted training | default prior | adjusted prior |
---|---|---|---|---|
SCTR | 24.9% | 66.9% | 0.33% | 1.81% (5.5x) |

Houdini | 8.2% | 19.5% | 0.15% | 1.02% (6.8x) |
Naum | 21.3% | 39.0% | 0.05% | 0.87% (17x) |
Scorpio | 20.1% | 50.3% | 0.07% | 1.09% (16x) |
Protector | 0.6% | 5.0% | 0.10% | 0.86% (8.6x) |
Vajolet | 4.7% | 14.8% | 0.17% | 1.32% (7.8x) |
Cheng | 15.8% | 53.0% | 0.01% | 0.38% (38x) |
As @killerducky pointed out earlier, we probably shouldn't touch the training until other things are fixed, so these numbers are at least reassuring in that if the network never got so biased to avoid these moves to begin with, they would pretty naturally find these correct moves with the default noise settings.
In terms of network progression, even with a clean start, priors could end up very low like these 0.0x% numbers because the value head hadn't learned to favor a position, so training search would give less visits. But I suppose that could be something revisited later if it seems to be stuck again and failing to generate useful training.
from lc0.
There was a request to check the latest lc0 test id14 4ce96dba to see what it thought of each of these games. Looks like the network already avoids most of these moves except a couple games and has trouble generating training data to increase prior for the move. Below are the average training using default noise as well as the priors for the move:
game | training | prior |
---|---|---|
SCTR | 10.8% | 0.06% |
Wasp | 8.2% | 0.14% |
EXchess | 2.0% | 0.04% |
Hakkapeliitta | 98.8% | 94.69% |
iCE | 23.9% | 0.27% |
Bobcat | 92.6% | 2.89% |
Houdini | 5.5% | 0.20% |
Naum | 16.4% | 0.07% |
Scorpio | 1.2% | 0.07% |
Protector | 0.2% | 0.07% |
Vajolet | 1.6% | 0.16% |

Here's a check to see if the network would have found the move if forced to explore at least 20 visits out of 2000:

So the network with its value and policy could generate valuable training data if search was biased the right away in almost all the cases. Unclear if this is a limitation on the size of the network.
I'm not sure if it's concerning yet that the network would generate average training quite a bit less compared to the previous comment with default training.

from lc0.
I analyzed id396 from @scs-ben compared to id395 for these positions, and some have significantly better average tactics training even though the same training data resulted in similar priors for the correct move for both networks. The main difference is that the value evaluation for the expected move is generally favorable, which drives more visits during search.
The Scorpio game in the previous comment shows the new network believes the move is winning (V: 3.05%) where the previous network thinks it's losing (V: -38.69%), so even though priors are very low around 0.2% for both, the id396's value results in 60.3% training up from 18.0%!
@killerducky is this change in value expected from 50-normalization? It should definitely help generate better training data in some cases! 👍

I wouldn't say it's directly expected. But r50 was breaking the net, so with it fixed hopefully the net will fix other things too, or we will find the next problem.

There looks to be quite a bit of difference between id401 and id402. I'm surprised at how much the value can change in just one network.

Here's the progression of priors for the 3 lc0 tests so far. Looks like after the learning rate change to 0.01 for test 3, the max change in prior was reduced from id250 averaging 7%, but then after id304, the changes jumped up to an average 23%.
from lc0.
Here's the behavior of test 3 searching for the best move for each of the board positions from this issue (i.e., load the position then go nodes 800
and see how many visits out of 800 without smart pruning):
Looks like it pretty solidly learned two: hakkapeliitta and bobcat; and conflicted learning two: houdini and ice. There were brief blips of learning then forgetting sctr, exchess and scorpio. And never really ever considered wasp, naum, protector, vajolet and cheng.
I would guess the conflicted learning is that the NN sees it like other similar positions, so it's constantly training two or more different correct moves. I'm not sure if this would be addressed by a larger network that could differentiate the positions better?
Here's the same analysis for Test 1 also learning hakkapeliitta and bobcat; briefly exploring houdini and ice; and none of the others after the initial noise:
And Test 2 also learned hakkapeliitta and bobcat; conflicted for sctr (and maybe scorpio at the end?); and none of the others after the initial noise:
For reference, id395 and later main networks after 50-normalization have learned only just hakkapeliitta and none of the others.
Edit: Test 4 (?? normally numbered 1-57, but I added 500):
Edit: Test 8 including value-only/policy-less search as dotted lines:

At least for these tactical positions where other moves would be significantly worse than the one correct play, increasing visits allows MCTS to eventually give enough visits to the higher prior moves to then find the hidden tactics.
So instead of adjusting noise in various ways, just simply doubling visits should lead to significantly higher visits to the correct move and consequently rapidly increasing the prior training above the noise threshold.
(Increasing visits improves policy head while keeping the existing noise settings, and increasing visits also improves value head while keeping existing temperature without needing #237.)
from lc0.
I reran the positions with 11089, and things definitely seem better than before finding 6 of 12 correct tactical moves with self-play settings and 800 visits.
