Just checking, dear @ABDanielleSmith
1) when did @JustinTrudeau get a mandate to buy a pipeline to cater to your province's needs ?
2) When did he get a mandate to shower oil compagnies with 18 billion $ of federal aid per year ?

Danielle Smith@ABDanielleSmith
The federal government does not have a mandate to bargain with Quebec separatists at the expense of Alberta, the West and the rest of the country. If the Liberals go down this path we need an election to be called immediately.

CoLLAs (lifelong learning) conference starts tomorrow!
CoLLAs 2026@CoLLAs_Conf
You can find all the 64 accepted papers (pdf) @CoLLAs_Conf #CoLLAs2022 and their video presentations here: virtual.lifelong-ml.cc. You can watch these video presentations even if you have not registered to attend the conference!

@HannesStaerk @dereklim_lzh @Josh_d_robinson @tesssmidt @optiML @HaggaiMaron @StefanieJegelka hey @dereklim_lzh, to produce the positional encoding you run the eigenspace projections through an invariant graph net and some other sequence network. can you say a bit on how you train those?
English
New GraphML explanation video is up! 🎉
@dereklim_lzh and @Josh_d_robinson explain their Sign- and Basis- invariant graph positional encoding. The future of Graph Transformers?👌

🧵1/3 In the past 2 years, models posted on the OGB-molHIV datasets saw their test score increase, but val decrease.
Models never stay on top of benchmarks for long. But, I'm proud to say that our models, PNA and DGN, have held the top spot on the val roc-aucfor almost 2 years!

Electric cars are cool but they seem to have a lot of serious flaws like having to rebuild the distribution system and reliance on some rare minerals. Making fuel from algae seems important to explore
X, The Moonshot Factory@Theteamatx
Algae can be turned into fuels like ethanol, diesel and jet fuel — but the process has always been prohibitively expensive. Now, researchers are using AI to augment algal growth, potentially turning these blue-green bacterial blooms into biofuel booms. spectrum.ieee.org/ai-could-power…

@pickover Looks like the flares happen mostly on the "tropics" parallels in this picture. I wonder if it's a coincidence or there's some physics explaining this

I love this, I'm betting there is a lot more ways discrete differential geometry can be used to make sense of gnns

@slackermanz WHAT? how this work exactly? what are the new rules?

It's amazing what can be found in Conway's #GameOfLife ..
.. with a few 'technical upgrades' expanding the parameter-space and running it on a GPU!
- Continuous State
- Multiple Neighborhoods
- Multi-channel (RGB) space
- Cross-channel coupling
- Dynamic Neighborhood Selection

Mindblowing

Equifax is selling access to people's salary data as part of an "employment verification solution" that includes:
Previous annual salaries
Previous weekly paycheck amounts
Previous addresses
Who accessed the report in the last 24 hours
Etc.

[🧠 collective intelligence 🧠] I've been intrigued by the cellular automata (CA) concept for a long time, and by the potential, mutually beneficial interaction between CAs and deep learning, so I decided to dig a bit deeper. Here are some interesting resources I found:

Is chaos actually hard to predict? For NeurIPS this year I made a database of 131 known strange attractors, and trained state-of-the-art forecasting models on each one, to try to figure this out (1/N): Paper: arxiv.org/abs/2110.05266 Dataset + Code: github.com/williamgilpin/…

@math3ma Do you know if the similar statement with quantum states and Von Neuman entropy is true? seems like it would follow if there is a quantum version of Faddeev-Leinster

Today I’m happy to share a new bit of math connecting ideas from information theory, algebra, and topology - all in new preprint on the arXiv! (arxiv.org/abs/2107.09581) This latest blog post takes a leisurely stroll through some of the ideas: math3ma.com/blog/entropy-a…
