Could Ukraine hold a presidential election right now? Will Europe use frozen Russian assets to fund war? How can Ukraine rebuild China ties? 'Ukraine is running out of men, money and time' At least four people, including a woman and her child, have been killed in Russian drone attacks on Ukraine, according to local officials. The Ukrainian air force said in a statement on Monday that Russian forces fired 11 ballistic missiles and 149 drones across Ukraine overnight.

Learning robot control policies by imitation [31]isan appealing approach toskill acquisition and has been successfully applied to several tasks, including locomotion, grasping, and even table tennis [8, 2, 25]. In this paradigm, expert demonstrations of robot motion are first recorded via kinesthetic teaching, teleoperation, or other input modalities.

They are able to learn anti-correlated instances, i.e., defaulting to "positive" labels until seeing a negative counter-example, which should not be possible for a correct MIL model.

Sharma et al. (2022) provide Y ang et al. (2022a) integrate Local SGDA with stochastic gradient estimators to eliminate the More recently, Zhang et al. (2023) adopt compressed momentum methods with Local SGD to increase the communication efficiency of the algorithm. For centralized nonconvex minimax problems, Y ang et al. (2022b) show that, even in deterministic settings, GDA-based methods necessitate the timescale separation of the stepsizes for primal and dual updates.
