Maxim Kashirin, PhD student New Bayesian Focal Loss Targeting Aleatoric Uncertainty Estimate: Pollen Image Recognition
Biological image recognition is one of the most challenging domains due to the similarity of species and errors in labeling. Pollen grain image classification heavily suffers from both problems preventing from building of well-calibrated recognition models. In our research, to alleviate aleatoric uncertainty we propose a new Bayesian Focal Softmax loss function, which provides a better estimation of aleatoric uncertainty and increases model performance. The proposed loss function fits single-label tasks with a small margin. The paper on the research is accepted to the CVMI workshop at CVPR.

The Security Service of Ukraine said in a tweet that it was able to effectively target Russian convoys near Kyiv because of messages sent to an official Telegram bot account called "STOP Russian War." As such, the SC would like to remind investors to always exercise caution when evaluating investment opportunities, especially those promising unrealistically high returns with little or no risk. Investors should also never deposit money into someone’s personal bank account if instructed. The message was not authentic, with the real Zelenskiy soon denying the claim on his official Telegram channel, but the incident highlighted a major problem: disinformation quickly spreads unchecked on the encrypted app. At its heart, Telegram is little more than a messaging app like WhatsApp or Signal. But it also offers open channels that enable a single user, or a group of users, to communicate with large numbers in a method similar to a Twitter account. This has proven to be both a blessing and a curse for Telegram and its users, since these channels can be used for both good and ill. Right now, as Wired reports, the app is a key way for Ukrainians to receive updates from the government during the invasion. "We're seeing really dramatic moves, and it's all really tied to Ukraine right now, and in a secondary way, in terms of interest rates," Octavio Marenzi, CEO of Opimas, told Yahoo Finance Live on Thursday. "This war in Ukraine is going to give the Fed the ammunition, the cover that it needs, to not raise interest rates too quickly. And I think Jay Powell is a very tepid sort of inflation fighter and he's not going to do as much as he needs to do to get that under control. And this seems like an excuse to kick the can further down the road still and not do too much too soon."
