QUESTION
I have a pyTorch-code to train a model that should be able to detect placeholder-images among product-images. I didn't write the code by myself as I am very unexperienced with CNNs and Machine Learning.
My boss told me to calculate the f1-score for that model and i found out that the formula for that is ((precision * recall)/(precision + recall)) but I don't know how I get precision and recall. Is someone able to tell me how I can get those two parameters from that following code?
(Sorry for the long piece of code, but I didn't really know what is necessary and what isn't)
ANSWER
Answered 2021-Jun-13 at 15:17You can use sklearn to calculate f1_score

Answered 2021-Jun-09 at 09:46The issue is that merge_probe_trial_dicts mutates the original list that is in df4 instead of creating a new one.
Just add .copy() as below and you should be good.

I need help with making tree from possible moves in game Othello, on which I will later use MiniMax algorithm. Game is played in Player vs AI mode and I am always "1" on board and AI is always "2" on board. This is how my current function for getting best move for AI looks like:
...ANSWER
Answered 2021-May-23 at 09:44You would need your recursive function to return a TreeNode instance, not a Tree instance. The top level call will then return the root node, which should then be assigned to the root attribute of a single Tree instance.
I would also suggest creating an Edge class, so you can store the information about the move that was played in the parent board in order to get to the child board.
If I understand correctly you want to separate the minimax/alphabeta algorithm from the actual game rules, and first create the tree of states (specific to the game), and then feed that to a generic minimax/alphabeta algorithm which can then be ignorant about the game rules, and just focus on the information in the tree.
Here is an idea for an implementation:

So I've been trying to make this turn-based battle and I ran into a slight issue. I can't seem to use the variables that are defined within the if statement. I tried declaring them global but that didn't work. Is there any way to solve this problem while still using if statements?
Here the code that I'm having issues with:

Answered 2021-May-22 at 10:29You're trying to access a variable before it's been declared.
You've got if spawn == "mandrake": before you declare spawn, move spawn = "mandrake" above the if statement.

I am currently doing this problem in cs50 AI where we need to make a minimax algorithm for playing tictactoe. My algorithm doesn't work at all (it is really easy to beat the computer) and I was wondering what I was doing wrong. I am also pretty sure that all my other functions are correct and that only the minimax function is incorrect. Would really appreciate any help, thank you all!
...ANSWER
Answered 2021-May-21 at 04:29You seem to have lots of unnecessary functions and your minimax code looks way too complicated than it needs to be. Basically you need 4 main functions for your game:
- Minimax itself
- Get all possible moves from a position (unless you want to do the loop inside minimax)
- Determine if a player has won
- Determine if board is full
Also, have you looked at the pseudo code for minimax from e.g. Wikipedia? :
