While they can't image black holes (yet?), graph NNs can help us research the cosmos! DeepSphere: a graph-based spherical CNN with approximate equivariance. Joint work with
@NPerraudin@tomekkacprzak and R. Sgier from@EPFL_en@SDSCdatascience@ETH_physics. Story in 6 tweets

Spinach is not a good source of iron. Amazing how myths persist when we don't pay attention (it was debunked in the 1930s). If you believed the myth from Popeye (as I did), do also know that its author chose spinach for vitamin A, not iron.https://twitter.com/m_deff/status/1222430331170643970 …

That's what focus brings. Free of bureaucracy, committees, teaching, supervising, grant writing, etc., researchers can research.https://twitter.com/tdverstynen/status/1221914455421980677 …

In Europe (at least in
and around), trains are more comfortable and not much slower than planes and cars. Both for local and long-distance trips (e.g., I took a 6h direct train from Basel to Amsterdam). I'm concerned about depending more on planes and cars if moving to SF. :/https://twitter.com/dhh/status/1216493011523244032 …Hvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte.

Just finished Bad Blood by
@JohnCarreyrou. It's infuriating how far you can get with plain lies. :/ Hopefully the majority will too see the truth in Trump and Brexiters, and they'll face a similar ending. PS: the book reads like a thriller. Highly recommended!pic.twitter.com/ZOy82tL3C5

We spend so much time discussing issues --- which is necessary to progress --- that we forget where we come from. Feels good to take some time to appreciate it. :) And

The universe is dangerous. Yet we don't perceive it and discover slowly. Most likely solution (the rare environment) to Fermi's paradox?https://twitter.com/universal_sci/status/1210794484163702785 …

New work "what graph neural networks cannot learn: depth vs width" (ICLR20) studies the expressive power of GNN: It provides sufficient conditions for universality and shows that many classical problems are impossible when depth x width < c n^p.

While Lisp's axiomatization of computing is intellectually beautiful and powerful, Lisp code is hard to read. I believe a more literate Lisp would go a long way towards adoption. And that would be a huge step forward for computing! https://twitter.com/paulg/status/1182918286150963200 …pic.twitter.com/aekgnUBNvS

Not surprised that UMAP's preservation of global structure is entirely due to initialization. Force layouts (used by UMAP & t-SNE) do local updates only. A contrario, Laplacian eigenmaps and PCA use the global structure. Init globally and fine-tune locally is the wining strategy.https://twitter.com/hippopedoid/status/1207999178015727616 …

What is so special about gender that it's ingrained in our languages? English would be as comprehensible with only "they" as a pronoun as with "she", "he", "they" (same with "their" and other languages). Why did it evolved gendered?

BTW, you can view the first term A^0 = I as skip connections.

GCN can only do low-pass filters because of the self-loops in the adjacency matrix that mix the 0- and 1-neighborhood. Guess what is the simplest fix? Use a polynomial. Even a first-order Y = X W_0 + A X W_1 (and that is ChebNet with K=2).https://twitter.com/ml_review/status/1132504140544921600 …

Nice article comparing features across some cloud services for reproducibility. Wish they spent more time talking about the means of production for these projects, which I see as a key differentiator and a big part of sustainability for open scholarshiphttps://twitter.com/benmarwick/status/1191745039879168000 …

Switzerland
elected its parliament for the next 4 years. Good in my opinion: more women (+10%), more green parties (+9%, mostly at the expense of the right), good balance. Bad: participation of 45% only (-3.5%).
