Sam Altman says we’re ‘in the singularity’ with AI. Here’s why he’s wrong

“We are now, like, in the singularity”. These are the words of Sam Altman, CEO of OpenAI, speaking on the Relentless podcast ...

If The AI Singularity Is Here, Where Is The Evidence?

AI is advancing rapidly, but what would prove we've reached the singularity? Here's the evidence experts say we'd need—and ...

Network structure influences self-organized criticality in neural networks with dynamical synapses

The brain criticality hypothesis has been a central research topic in theoretical neuroscience for two decades. This hypothesis suggests that the brain operates near the critical point at the boundary ...

Wide and deep neural networks achieve consistency for classification

While neural networks used in practice are often very deep, the benefit of depth is not well understood. Interestingly, it is known that increasing depth is often harmful for regression tasks. In this ...
