GPT-2 Agents

  • Fixed the regex in ChessMovesToDb
  • More work on finding closest neighbors.
    • Maybe keep a record of the number and type of pieces that are used?
    • Looks like the basics are working. Here’s the test graph:

known_nearest

    • And here are the results. I made the code so that it only shows each neighbor once, but it may be useful to keep track of the number of times a neighbor shows up in a list. This might not be important in chess, but in less structured text environments (RPGs to Reddit threads), it may be valuable: 
      find_closest_neighbors(): nodes = ['a', 'b', 'c', 'd', 'e', 'f', 'g']
{'node': 'a', 'known_nearest': ['f', 'd']}
{'node': 'b', 'known_nearest': ['f', 'd']}
{'node': 'c', 'known_nearest': []}
{'node': 'd', 'known_nearest': ['f', 'a', 'b', 'g']}
{'node': 'e', 'known_nearest': []}
{'node': 'f', 'known_nearest': ['a', 'g', 'd', 'b']}
{'node': 'g', 'known_nearest': ['f', 'd']}

       

    • At this point it’s not recursive, but it could be. I’m worried about combinatorial explosion though

  • Started on common neighbor algorithm. Definitely a good place for recursion
  • Generating larger file

adjacency

moves

  • If you look at the center of the plot and squint a bit, you can see a bit of the grid:

networkx

  • There is an error: The string ‘, White moves pawn from h3 to g4. White takes black pawn. LCZero v0.24-sv-t60-3010 moves black knight from h5 to g7. White moves pawn from g4 to h5. LCZero v0.24‘ is parsing incorrectly due to the truly bizarre name (The little known Grand Master LCZero v0.24-sv-t60-3010). Need to fix the regex. I think I just need to make it so that there has to be a space in front and a space/period after.

  • Alex had a really good insight in that groups that are working at coming to consensus use terms to discuss their level of agreement that are independent of the points being argued. That’s could really be important in text analysis.

GPT-2 Agents

  • Try to make a adjacency matrix from the DB. That may work, but it sure doesn’t generate anything human-readable. Need to roll my own
  • After accidentally blowing away my database (Yay, backups!), I’m reading in the network. This actually looks really good. I’d not an 8×8 grid, but the system found 63 nodes, and you can see that many adjacent nodes are connected:

networkx

  • You can also see that common moves, such as e2 and d2 are in the center and well connected.
  • Hand-rolled an adjacency matrix using pandas.DataFrame and exported to Excel. I have to think about what this means now. I think that it’s clear that moves tend to be nearby. I’m clearly not setting something right, because I don’t have the weight of the edge between nodes (I’m currently using the number of times a node was visited). Now I need to figure out how to use this:

Hey! My dissertation is online now!

Optimizing Multiple Loss Functions with Loss-Conditional Training

  • The idea behind our approach is to train a single model that covers all choices of coefficients of the loss terms, instead of training a model for each set of coefficients. We achieve this by (i) training the model on a distribution of losses instead of a single loss function, and (ii) conditioning the model outputs on the vector of coefficients of the loss terms. This way, at inference time the conditioning vector can be varied, allowing us to traverse the space of models corresponding to loss functions with different coefficients

GPT-2 Agents

  • Applied to get on the OpenAI API waitlist
  • Started figuring out igraph. Welp, it doesn’t plot because cannot load library ‘libcairo-2.dll’: error 0x7e Diesn’t seem to be a good fix. It’s a shame, because igraph seems to be great for analyzing graphs mathematically. Removing everything
  • Looks like I can use networkx combined with networkx_viewer (pypi)(github). Look into that next. Upgraded from 2.1 to 2.4
  • Pulled my NetworkxGraphing.py class over from Antibubbles and verified that it still works!

  • Drawing the embeddings. Fun, but not really useful. And this is kind of my point about embeddings like W2V that don’t take into account the trajectory of the sentence the word is part of. We know that the structure of the board is represented in the text. We need a more sophisticated embedding to to extract it

Phil 6.9.20

I’ve been thinking about writing a paper about how the development of conspiracy theories resembles the mode collapse condition in GAN creation. There is some recent research in the GAN community on developing tools for detecting mode collapse (Jai & Zhao, 2019) that I think could be extended to identifying conspiracy theories and the processes that create them. Maybe for ICTAI 2020?

Studying Programming in the Neuroage: Just a Crazy Idea?

  • What we were proposing to do was simple yet ambitious. Using functional magnetic resonance imaging, we might better understand what goes on in the minds of programmers as they read and understand code.
  • The results indicated that a specific network of brain areas in the left hemisphere was used by participants to understand code, including areas related to working memory, divided attention, and reading comprehension. Surprisingly, we did not observe cognitive processes related to mathematical and logical reasoning, which would be consistent with the perspective that programming is a formal, logical, and mathematical process.

  • Create probes for each piece, like:

  • Then see if it’s possible to connect one piece to another piece using a “from/to chain” across multiple pieces. There will probably be some sort of distribution where the median(?) value should be a set of adjacent squares.
  • The connections can be tested by building adjacency matrices by piece and by move number range
  • Started ChessMovesToDb. Might as well work on the tricky parse of  “The game begins “. Making progress. My initial thought on how to parse moves doesn’t handle weird openings like “4.e3, Gligoric system with 7…dc” Need to strip to the the first occurance of “move”, I think: 
    white uses the Nimzo-Indian opening. and black countering with 4.e3, Gligoric system with 7...dc. White moves pawn from d2 to d4. Black moves knight from g8 to f

GPT-2 Agents

  • Thinking about how to parse the data to build maps.
    • Clearly, there are black and white agents (the players). Option 1 would be to simply collect the from-to points at the player level
    • One step down would be the piece family, pawns, rooks, bishops. The king and queen would be single instances
    • The most granular would be to track the individual pieces.
    • The issue I’m struggling with is when pieces pass over squares rather than through them. There is no explicit d3 when white moves the pawn from d2 to d4. Trying to think of the best way to uncover the latent information.
    • I think a good way to procrastinate about this problem is to parse the games into a database of moves. The format is always “<player/color> moves <(color)piece> from <start> to <end>. There is additional information as well (game, players, move number), but that could be added later.

  • Finished finetuning the model yesterday, and tried running it with the following seeds: 
    text_list = ['The game begins as ',
             'White moves ',
             'Black moves ',
             'In move 1, ',
             'In move 40, ']
  • The results are pretty incredible:

generated_chess

  • Opening moves (“The game begins as”, “In move 1”) make sense. White always moves first. Pieces move in reasonable, permissible ways (e.g d3 to d4)
  • The model knows how to take pieces correctly. The red lines connect moves by White and the counter-move by black, then the taking of the piece.
  • Moves that occur later in the game are also sensible. (“In move 40”, “White moves”. “Black moves”)
  • Names occur very infrequently. And Loek is probably the most frequent name, since his entire career is in a pgn file
  • I think the next steps are:
    • Create marker text for SBoW analysis, like  “In move 1, White moves pawn from d2 to d4. Black moves knight from g8 to f6.“, and “In move 40, White moves rook from d1 to d7. Black moves pawn from e5 to e4.” so that I can use the antibubble analytics
    • Create a parser that looks for the movements of particular pieces (white pawns, black knights, etc) and see if I can build a map from that using the agent tools. Pawns and kings may provide the projection, while other pieces move over that

    1. h4 h5 2. Rh3 Rh6 3. Ra3 Ra6 4. Rh3 Rh6 5. 1/2-1/2
  • And it’s working! I did have to adjust the subtraction order to get pieces to move in the right direction. It even generates game text: 
    Game.parse_moves(): Move1 = ' h4 h5 '
Evaluating move [h4 h5]
piece string = '' (blank is pawn)
piece string = '' (blank is pawn)
Game.parse_moves(): Move2 = ' Rh3 Rh6 '
Evaluating move [Rh3 Rh6]
piece string = 'R' (blank is pawn)
piece string = 'R' (blank is pawn)
Game.parse_moves(): Move3 = ' Ra3 Ra6 '
Evaluating move [Ra3 Ra6]
piece string = 'R' (blank is pawn)
Chessboard.check_if_clear() white rook is blocked by white pawn
piece string = 'R' (blank is pawn)
Chessboard.check_if_clear() black rook is blocked by black pawn
Game.parse_moves(): Move4 = ' Rh3 Rh6 '
Evaluating move [Rh3 Rh6]
piece string = 'R' (blank is pawn)
piece string = 'R' (blank is pawn)
Game.parse_moves(): Move5 = ' 1/2-1/2'
Evaluating move [1/2-1/2]

The game begins as white uses the Polish (Sokolsky) opening opening. 
Aye Bee moves white pawn from h2 to h4. Black moves pawn from h7 to h5.
White moves rook from h1 to h3. Cee Dee moves black rook from h8 to h6.
White moves rook from h3 to a3. Black moves rook from h6 to a6.
Aye Bee moves white rook from a3 to h3. Black moves rook from a6 to h6.
In move 5, Aye Bee declares a draw. Cee Dee declares a draw
  • Ok, it’s not quite working. I can’t take pieces any more. Fixed. Here’s the longer sequence where the white rook takes the black rook and retreats back to its start, moving past the other white rook:

    The game begins as white uses the Polish (Sokolsky) opening opening. 
White moves pawn from h2 to h4. Black moves pawn from h7 to h5.
Aye Bee moves white rook from h1 to h3. Black moves rook from h8 to h6.
In move 3, White moves rook from h3 to a3. Black moves rook from h6 to a6.
White moves rook from a3 to a6. White takes black rook. Black moves pawn from c7 to c6.
In move 5, White moves rook from a6 to a3. Black moves pawn from d7 to d6.
White moves rook from a3 to h3. Black moves pawn from e7 to e6.
In move 7, White moves rook from h3 to h1. Black moves pawn from f7 to f6.
In move 8, Aye Bee declares a draw. Cee Dee declares a draw
  • It’s a little too Friday to try a full run and find new bugs though. Going to work on the paper instead

D20 – Ping Zach. Made contact. Asked for a date to have the maps up or cut bait.

GOES

  • Add accuracy/loss diagram and paragraph – done
  • Finish first pass
  • Nope, All hands plus 90 minutes of required cybersecurity training. To be fair, the videos were nicely done, with a light touch and good acting.

Agents and expensive information

  • Antonio sent a note asking if I’d be interested in contributing to a chapter. Sent him this response:
    • There is something that I’d like to explore that might fit. It’s the idea that in most environments, agents (animal, human, machine, etc.) are incentivized to cheat. I think this is because information is expensive to produce, but essentially free to copy. The problem is that if all the agents cheat, then the system will collapse because the agents become decoupled from reality (what I call a stampede). So the system as a whole is incentivized to somehow restrict cheating.
    • I think this could be very interesting to work through, but I don’t have a model (or even an approach really) developed that would describe it. I think that this might be related to game theory, though I haven’t found much in the literature.

GPT-2 Agents

  • Working on building a text corpora. Going to add a search for “Opening” and “Variation” which I’ll try before using the DB version – done
  • Having some problem that starts after a few games. Found the culprit game. Will work on tomorrow. It might be tied to a linefeed?

GOES

  • Working on the GVSETS paper and slide deck

Had a good, cathartic ride yesterday:

GPT-2 Agents

  • I’ve been working on the PGNtoEnglish class and was having an odd bug where occasionally a piece would pull a piece from the other side of the board. Since it was intermittent, it required many print statements and searching through the logs for “black knight”

  • My problem was in forgetting how Python indexes into arrays. Here’s the code in question:

python

  • When I first wrote this, I had to deal with a lot of potential coordinates that were off the board, with indexes like (-2, -1), or (10, 8) for an 8×8 board. I thought to handle this with a try/except on IndexError (the bottom highlight). In other languages this would have worked, but Python allows negative indexes. Ooops! Adding the test for either index being negative (the top highlight) fixed that bug

D20

  • Ping Zach – done

GOES

  • Write up code review thoughts for Erik -done
  • Add n_critic to base class, along with adjustable false flag value
    • First, making sure that everything still works. Seems to.
    • Here’s the best I can do today, using the OneDGAN2a class with an RMSProp(lr=0.0005)

epochsNoise_trainedacc_loss

  • Assemble all the bits for an example
    • Verified that the InfluxTestTrainBase still works, and it’s using the InfluxDB values
    • Assemble all the bits for an example
      • Created a NoiseGAN2 with the same amount of points as the InfluxTestTrainBase model – done. Looks real good on the noise, too:

epochsNoise_trainedacc_loss

  • How to trim the columns on a 2D Numpy array: 
    results = self.ifq.run_query(self.bucket, begin, end, filter_str)
results = self.ifq.to_nd_array(results)
results = np.delete(results, slice(clamp, None), 1)
predict_table = model.predict(results)
  • Here’s all the parts nailed together:
  • Start the paper and the deck

ML Group

  • Need to create a walkthrough of coding practices for next week. I think I’ll use the trajectory of the GAN coding as the basis
