I am looking for a website which existed a couple of years ago and listed use cases for #MachineLearning. Next to each use case, papers solving the task were listed including the f1 score or other success metrics.
It was extremely useful to see which approaches can be applied to each use case like document classification, image recognition,

Egal, ob das von vornherein so geplant war, oder die Erkundung tatsächlich so schnell abgeschlossen wurde: Der Zeitpunkt des Abzugs so kurz nach Trumps Zolldrohung ist maximal unklug und obendrein schlecht kommuniziert. #Trump wird das als Einknicken / Angst / Schwäche wahrnehmen. Die paar Leute hätte man problemlos noch ein paar Tage auf

Noch am heutigen Sonntag soll das 15-köpfige Erkundungsteam die Insel wieder verlassen.

This sucks, but I don’t think any organized constituency is going to fight it so it’s as good as law. Coming to SF: more businesses where you can’t buy anything without being added to their email list for the rest of your life.

‘Ethos of inclusivity’ no more: S.F. looks to repeal law requiring stores to accept cash
Seven years after San Francisco passed a law requiring brick and mortar stores to accept cash from customers, citing an “ethos of inclusivity,” city leaders are seeking to repeal it.

"Both candidates agreed that Market Street should be reopened to cars (a few people booed, then some cheered). They also both agreed that new housing developments should include more parking."
No problem for the "urbanists" at SF YIMBY, who just endorsed Sherrill.

On the Complexity of Maximal/Closed Frequent Tree Mining for Bounded Height Trees

Abstract: In this paper, we address the problem of enumerating all frequent maximal/closed trees. This is a classical and central problem in data mining. Although many practical algorithms have been developed for this problem, its complexity under ``realistic assumptions'' on tree height has not been clarified. More specifically, while it was known that the mining problem becomes hard when the tree height is at least 60, the complexity for cases where the tree height is smaller has not yet been clarified. We resolve this gap by establishing results for these tree mining problems under several settings, including ordered and unordered trees, as well as maximal and closed variants.

Abstract: We present a novel single-photon detector based on a vacuum tube incorporating a photocathode, a microchannel plate (MCP), and a Timepix4 CMOS ASIC functioning as a pixelated anode. Designed to handle photon rates up to 1 billion per second across a 7 cm$^2$ active area, the detector achieves outstanding spatial and temporal resolutions of 5-10 $\mu$m and below 50 ps r.m.s., respectively.
The Timepix4 ASIC comprises approximately 230,000 pixels, each integrating analog and digital front-end electronics. This enables data-driven acquisition and supports data transmission rates up to 160 Gb/s. External FPGA-based electronics manage both configuration and readout.
In order to test the timing performance of the Timepix4 ASIC we performed preliminary characterization of an assembly bonded to a 100 $\mu$m thick n-on-p silicon sensor using a pulsed infrared laser, which demonstrated a per-pixel timing resolution of 110 ps, with cluster-based averaging methods improving to below 50 ps.
Six prototype detectors incorporating different MCP stack configurations and end-spoiling depths were produced by Hamamatsu Photonics. We report on their characterization, including dark count rates, gain, and spatial and timing resolutions, assessed both in laboratory conditions and during a test-beam campaign at CERN's SPS facility.

Joe Eskenazi's @… column today speculates that Connie Chan and allies will run a doomed prop to close Sunset Dunes park, just to turn out voters for Chan.
But a good chunk of No on K voters are in congressional district 15, outlined, and can't vote for Chan. #sfpol<…
