Alright so you have a list of geocoordinates (for example maybe street sensors) and you want to create an adjacency matrix to feed into your PyTorch or Tensorflow GCN model such as the A3T-GCN. This tutorial uses OSMnx to measure the distance of optimal paths between each of the geocoordinates…

The greatest misunderstanding on finance Twitter is central bank lingo. For the past decade and a half tweeps have been yelling that quantitative easing QE is going to cause hyperinflation and the end of the US Dollar. None of these doomsday predictions have materialized. …

You might not like the new owner and are worried about you data. Perhaps you’re a journalist who quickly needs to scrub tweets. Maybe you just want delete your childish embarrassing tweets from when you were young. You want to start over. Turns out many services only delete the last…
