Preconditioned subgradient method for composite optimization: overparameterization and fast convergence
Composite optimization problems involve minimizing the composition of a smooth map with a convex function. Such objectives arise in numerous data science and signal processing applications, including phase retrieval, blind deconvolution, and collaborative filtering. The subgradient method achieves local linear convergence when the composite loss is well-conditioned. However, if the smooth map is, in a certain sense, ill-conditioned or overparameterized, the subgradient method exhibits much slow…

You can't “overbuild” internet infrastructure. Just like highways, demand always catches up. Except fiber doesn't kill forests.

Good Morning #Canada
On this day in 1948, the longest serving political leader in the British Commonwealth retired. William Lyon Mackenzie King served 21 years and 154 days as Prime Minister of Canada, in non-consecutive terms, from 1921–1926, 1926–1930, and 1935–1948. He led Canada through the Great Depression, introduced Old Age Pensions, nationalized the Bank of Canada, passed the 1938 National Housing Act to improve housing affordability, established the Canadian Broadcasting Corporation, Trans-Canada Air Lines, and the National Film Board, and implemented Unemployment Insurance. His government was also responsible for Japanese Internment Camps, and he believed strongly in the occult.
This video from TVO is an excellent overview of King's career. It's probably a two coffee viewing this morning if you have the time, but IMO worth the investment.

I wish mastodon had a “throttle” feature. https://merveilles.town/@lrhodes/115379960146577252

If I am coming to Discord to ask a question, noting that "I've tried all the obvious stuff", you can safely assume I also have run web searches. Pasting the Google AI Overview response for my question is not helping.

qa_user: User interactions on Q&A websites (2016)
Networks of interactions among users from four online Q&A sites: Stack Overflow, Math Overflow, Super User, and Ask Ubuntu. A directed edge (i,j) indicates a user i responded to user j's post. Edges are timestamped. For each Q&A site, four differently defined networks are provided, based on the definition of an edge: (i) a user answered a question, (ii) a user commented on a question, (iii) a user commented on an answer…

In much the same way we want useful #privacy focused, secure software, but the techbros keep delivering insecure #AI focused insecure nightmares, I wish the food industry would stop trying to sell us #ultraprocessed #overpackaged and mostly marketing driven guff and start turning their brilliant minds to real problems.
Why can't I have a delicious #vegan #plantbased cheese that doesn't cost the earth available at my local supermarket?
It's as if the brightest minds of each generation get turned to the wrong things - like ever more sophisticated ways to keep scrolling, or physics graduates who became quants and helped cause the financial crisis...

stackoverflow: Stack Overflow favorites (2011)
A bipartite network of users and the posts they have favorited, from the online Q&A site Stack Overflow. An edge (i,j) connects a user i to a post j if that user "favorited" that post (a kind of a rating). Edges are timestamped.
This network has 641876 nodes and 1301942 edges.
