Deadly drone strikes cloud US-brokered Russia-Ukraine talks in Geneva
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' A deadly exchange of drone strikes has killed one person in Ukraine and one in Russia and cast doubts on the prospects of a ceasefire before another round of negotiations to end the war next week. News of the deaths comes as Ukrainian President Volodymyr Zelenskyy and US Secretary of State Marco Rubio signalled hurdles to reaching an agreement in Geneva as the conflict is about to enter its fifth year.
Breaking the Activation Function Bottleneck through Adaptive Parameterization

Adaptive parameterization is a means of increasing this flexibility and thereby increasing the model's capacity to learn non-linear patterns. We focus on the feed-forward layer, f(x):= φ(W x+b),for some activation functionφ: R 7 R. Define the pre-activation layer as a = A(x):= Wx+band denote byg(a):= φ(a)/athe activation effect ofφgivena, where divisioniselement-wise.
