@hanxin2000 @hackink @thsottiaux 你没用 sub2api 吧？

@Khazix0918 太正常了，用户数一直在涨，硬件相对不涨的话，肯定得砍额度

@thegautamkamath I was wondering how to set positional embedding in such case.

In this study, we propose an entropy-based method to estimate transit passengers’ trip origin-destination using smart card data. The method is powerful in unveiling travel regularity exhibiting in passengers’ mobility sequences. @Transport_ELS

At @geodatascience, we are teaching ca.200 students how to do Geographic Data Science in Python/R yearly. This term they'll have to install each stack on their own machines. To make these efforts smooth, we have prepared a set of open guides available at: https://t.co/A3PFDKo1L5

New work led by Da @radar_da_lei out in TR-C. We develop a method based on Temporal Motif to identify individual travel patterns. Results help to understand transit riders’ travel behaviour in terms of the spatiotemporal connections between trips

In comparison to drones that use standard cameras, which can take as much as 40 milliseconds to react, a drone equipped with event cameras and running on an algorithm reacted on an average of 3.5 milliseconds. ($) @SciRobotics https://t.co/mKdHVVIn7Y

Energy-Based Models FTW.

A second-year grad student and his advisers have broken through a four-decades-old logjam in the traveling salesperson problem, one of the most famous problems in computer science--my latest for @QuantaMagazine https://t.co/oo8o2TJkIa

A new paper with @DV_Jonas is out in TRD. We find that the built environment imposes non-linear effects on walking time among older adults. Ultra-densely populated areas and excessively mixed land uses may lead to a decline in walking.

I'm happy to announce a new project, called Netzschleuder: https://t.co/SnBeOc5Pdk

This is a network data catalogue and repository. It currently contains 257 datasets totaling 3,916 individual networks (94,956 if you include a big @openstreetmap trove).

You should know: it's very easy to find identities and concise approximations with symbolic regression - see below

Our last paper "Dynamics of heuristics selection for cooperative behavior" is now out in the arXiv (https://t.co/SsY0Rcejzo). Here, we study the emergence and fixation of cooperative strategies through a model of heuristics selection based on evolutionary algorithms.

Researchers have created a new framework to optimize city layouts by modeling the ideal placement of vital institutions such as hospitals and fire stations, which could help make urban life less costly and improve air quality. https://t.co/NdLzaKsIvA @ScienceAdvances

This morning your @LATdatadesk is releasing census-error-analyzer, a Python tool for examining the margin of error in @uscensusbureau data.

It lets you quickly compare two estimates to see if they are truly statistically different.
