Azerbaijani Checkpoint to the Lachin Corridor at the Hakari Bridge, viewed from Kornidzor, Republic of Armenia. The checkpoint was installed on April 23, 2023 in violation of the Tripartite Ceasefire Agreement that ended the 2020 war. The Lachin corridor [a] was a mountain road in Azerbaijan that linked Armenia and Nagorno-Karabakh. [1]
In September 2022, Meta announced that PyTorch would be governed by the independent PyTorch Foundation, a newly created subsidiary of the Linux Foundation. [ 24 ] PyTorch 2.0 was released on 15 March 2023, introducing TorchDynamo , a Python-level compiler that makes code run up to 2x faster, along with significant improvements in training and ...
Global map of lightning frequency--strikes/km 2 /yr. The high lightning areas are on land located in the tropics. Areas with almost no lightning are the Arctic and Antarctic, closely followed by the oceans which have only 0.1 to 1 strikes/km 2 /yr. The map on the right shows that lightning is not distributed evenly around the planet. [5]
Blitzortung (German for "lightning direction-finding", German pronunciation: [ˈblɪtsˌɔʁtʊŋ]) is an informal, non-commercial group of citizen scientists supported by professional scientists. Active since 2005, [ 1 ] station operators manage a worldwide network of ~1800 active VLF radio wave receiver stations in 83 countries. [ 2 ]
A lightning detector is a device that detects lightning produced by thunderstorms. There are three primary types of detectors: ground-based systems using multiple antennas, mobile systems using a direction and a sense antenna in the same location (often aboard an aircraft), and space-based systems .
Catatumbo lightning occurs over and around Lake Maracaibo Catatumbo lightning usually develops between 8°30′N 71°0′W / 8.500°N 71.000°W / 8.500; -71.000 ( Approximate outer limit ) and 9°45′N 73°0′W / 9.750°N 73.000°W / 9.750; -73.000 ( Approximate outer limit ) , toward the west
Lightning Activity Levels Level Description 1 No thunderstorms: 2 Isolated thunderstorms. Lightning is very infrequent, 1–5 cloud-to-ground strikes in a five-minute period. 3 Widely scattered thunderstorms. Lightning is infrequent, 6–10 cloud-to-ground strikes in a five-minute period. 4 Scattered thunderstorms.
For many algorithms that solve these tasks, the data in raw representation have to be explicitly transformed into feature vector representations via a user-specified feature map: in contrast, kernel methods require only a user-specified kernel, i.e., a similarity function over all pairs of data points computed using inner products.
