A cool publication being the result of great teamwork at #sdsc
Thank you to my co-authors!
Very happy to announce that our #paper “What You See is What You Classify: Black Box Attributions” was accepted at #NeurIPS2022. We tackle a fundamental problem in modern #AI & #ML: a lack of transparency of black-box models.

Do you wonder how the recent heavy rains and thunderstorms affect Swiss lakes? Checkout our blog post bit.ly/3yt8hRK to learn about how we accurately simulate and forecast lake dynamics, & see our user-friendly portal!@EawagResearch

[Advanced] Intuitively, one could think that the projection onto the unit simplex is a simple rescaling. In most of the cases, it is not! You can check algorithms for the projection here. arxiv.org/pdf/1101.6081.pdf

Last version of @kevskibombom's book. A reference! probml.github.io/pml-book/bo… #ProbabilisticMachineLearning
Amazing! A #comic to learn on #ReinforcementLearning and pretty good it I would say. medium.com/hackernoon/intuit…

Conditional independence of entries of Gaussian vectors defines a graph associated to the inverse of the covariance (precision matrix). Graphical Lasso estimates a sparse graph by l^1 penalizing the maximum likelihood estimator. en.wikipedia.org/wiki/Graphi…
I love how problems were solved before the computer era. Such an elegant solution! Thanks @gabrielpeyre for the Oldies but goldies series...
Oldies but goldies: Joukowsky, N.E., Über die Konturen der Tragflächen der Drachenflieger, 1910. The Joukowsky conformal map solves airfoil design in the pre-computer era. en.wikipedia.org/wiki/Joukow…
[Advanced] Curious how the projected gradient descent method can be derived? Nice notes by Thibaut Lienart. tlienart.github.io/pub/csml/…
Definitely a very useful tool. But how much will our politicians consider it when taking decisions?
Terrestrial #ecosystems help mitigate climate change by absorbing large amounts of #carbon from the atmosphere. A new study now confirms that changing #climate conditions could reduce this effect. ethz.ch/en/news-and-events/e…

Three weeks left to apply! Looking forward to extend our team and design proteins with AI.
We are #hiring a postdoc🧐to work on the intersection between #AI and computational protein design. The project will be carried out at EPFL in collaboration with @befcorreia, @mmbronstein, @trekkinglemon, and @SDSCdatascience. More information below 👇
Spread the word!🗣️
Nice blogpost about the Wasserstein distance and the Kantorovich-Rubinstein Duality. To read if you like WGANs.

Carbon-neutral #aviation is possible, but in future, aircraft are likely to continue to be powered by fossil #fuels. The #CO2 they emit must be systematically stored underground. @paul_gabrielli ethz.ch/en/news-and-events/e…

You asked for an efficient algorithm for non-convex optimization for Christmas? It won’t be possible unless you have a lot of smoothness. See why in this month blog post.

Principal component analysis and non-negative matrix factorization are two particular of non-convex matrix factorization problem. They differ by the constraints on the atoms D and coefficients X. en.wikipedia.org/wiki/Princi… en.wikipedia.org/wiki/Non-ne…

When I'm sometimes asked 'When will there be enough [women on the Supreme Court]?' and I say 'When there are nine,' people are shocked. But there'd been nine men, and nobody's ever raised a question about that."
