A cool publication being the result of great teamwork at #sdsc
Thank you to my co-authors!

[Swiss Data Science Center @SDSCdatascience]

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 https://t.co/8RIF5w1Uhy to learn about how we accurately simulate and forecast lake dynamics, & see our user-friendly portal!@EawagResearch

@thoefler The challenge is finding the sparsity pattern. :-)

[Nathanaël Perraudin @NPerraudin]

A simple way to start: https://t.co/gokEndac70

[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. https://t.co/xXnf05gpgK

Last version of @kevskibombom's book. A reference! https://t.co/miHpOEsTuc #ProbabilisticMachineLearning

[Nathanaël Perraudin @NPerraudin]

Amazing! A #comic to learn on #ReinforcementLearning and pretty good it I would say. https://t.co/T9cxcTvn2i

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. https://t.co/pLMs6zu1Ky

I love how problems were solved before the computer era. Such an elegant solution! Thanks @gabrielpeyre for the Oldies but goldies series...

[Gabriel Peyré @gabrielpeyre]

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. https://t.co/FFEypwJ8W1

[Advanced] Curious how the projected gradient descent method can be derived? Nice notes by Thibaut Lienart. https://t.co/OTp9POmDI6

[Nathanaël Perraudin @NPerraudin]

Definitely a very useful tool. But how much will our politicians consider it when taking decisions?

[ETH Zurich @ETH_en]

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. https://t.co/8DoveRYa7j

[Advanced] Want to learn about Sinkhorn divergences? Nice presentation by Aude Genevay @a_gnv:

Three weeks left to apply! Looking forward to extend our team and design proteins with AI.

[Nathanaël Perraudin @NPerraudin]

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 https://t.co/HyrVpKqbb2

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.

The spherical Laplacian defines a set of orthogonal eigenspaces spanned by spherical harmonics. Display here is a random evolution in each space. https://t.co/ZmTOuUgJEr

How roots influence #ClimateChange: Soils play a major role for a stable state of the #Earth system. Milena Perraudin investigated in her master's thesis one of the most hidden parts of the terrestrial carbon cycle. https://t.co/NZ9GULKRie #125GIUZ #soilcarbon

[Gabriel Peyré @gabrielpeyre]

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. https://t.co/TAWN78orhy https://t.co/knuRHQvKp6
