Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

Does it work and how well does it work?

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

Yeah, interesting.

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

Because you know, neural networks learn statistics of increasing complexity as you train them for longer and as the models get bigger and so on.

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

And do you notice some, you know, like, for example, would a linear data model bias on simpler features or does it seem to work on more complex models as well?

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

Very cool.

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

So you're building this supervised regression model and you're sampling subsets of the data to train it.

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

What's the kind of the methodology there?

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

How do you sample the subsets?

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

So on this surrogate model, I mean, what is a good output to track, if that makes sense?

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

I mean, let's say we're doing classification or something like that.

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

What should we track?

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

So what's the difference between, because obviously we're talking about the surrogate model that has this more abstract notion of data set statistics.

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

I mean, how does that compare to just say, doing analysis on a specific model?

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

So when we've got this data model, what kind of stuff can we do with it?

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

One of the things you looked at in the paper was the strength of the embeddings of the data model versus using, say, the penultimate layer in the original model.

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

How does that work?

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

Yeah, so what did you find?

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

So, I mean, I suppose you can compare classes of learning algorithms, but these are also, I mean, potentially class specific.

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

So could you use them to kind of figure out confusion between classes and stuff like that?

Machine Learning Street Talk (MLST)
Adversarial Examples and Data Modelling - Andrew Ilyas (MIT)

Cool.
