@reiver@ProofOfLogic@AlleleOfGene These can deliver effective classifiers, with low computational cost but they don't model reality well.2 replies 0 retweets 3 likes -

@MakerOfDecision By "modelling reality" are you referring to interpretability of the model? … cc:@ProofOfLogic@AlleleOfGene1 reply 0 retweets 2 likes -

@MakerOfDecision …If "yes", then I'd agree; ANNs are infamous for not being interpretable :-) cc:@ProofOfLogic@AlleleOfGene1 reply 0 retweets 2 likes -

@reiver@ProofOfLogic@AlleleOfGene but they are not for representing causal effects, just accurate predictions conditional on training.1 reply 0 retweets 0 likes -

@reiver @ProofOfLogic @AlleleOfGene In theory, you can train a NN to predict a causal phenomenon, with the right training data - but

@reiver@ProofOfLogic@AlleleOfGene it's not generally the right tool for the job. (It still works because NNs are a universal approximator)0 replies 0 retweets 2 likesThanks. Twitter will use this to make your timeline better. UndoUndo
