What activation function does the human brain use?

The thing you were reading about is known as the action potential. It is a mechanism that governs how information flows within a neuron. It works like this: Neurons have an electrical potential, ...

How powerful a computer is required to simulate the human brain?

H+ magazine wrote an estimate in 2009 that seems broadly comparable to other things I've seen; they think the human brain is approximately 37 petaflops. A supercomputer larger than that 37 petaflop ...

Is there a rigorous proof that AGI is possible, at least, in theory?

A strong reason why people think the mind can be implemented on a Turing Machine stems from the Computational Theory of Mind (CTOM), which is the leading theory of mind for now. There are lots of ...

How powerful a computer is required to simulate the human brain?

The human brain contains about 100 billion neurons ($10^{11}$) and about a hundred trillion synapses ($10^{14}$). Each neuron can fire about 100 times a second. If we model the brain as a simple ...

What activation function does the human brain use?

The brains of mammals do not use an activation function. Only machine learning designs based on the perceptron multiply the vector of outputs from a prior layer by a parameter matrix and pass the ...

Is some kind of dropout used in the human brain?

The human brain works by having neurons constantly fire at different rates. So, if the firing rate increases, the neuron is transmitting overly exciting or calming information to further neurons ...

What makes the animal brain so special?

One probable hardware limiting factor is internal bandwidth. A human brain has $10^{15}$ synapses. Even if each is only exchanging a few bits of information per second, that's on the order of $10^{...

What is the difference between human brains and neural networks?

One incredibly important difference between humans and NNs is that the human brain is the result of billions of years of evolution whereas NNs were partially inspired by looking at the result and ...

Is there any artificially intelligent system that really mimics human intelligence?

As far as emulating an intelligent being, no. There are a few different potential architectures for possible AGI. Many of these are extremely infantile, as the bulk of AI research is in narrow AI, ...

Are convolutional neural networks inspired by the human brain?

Yes, CNNs are inspired by the human brain [1, 2, 3]. More specifically, their operations, the convolution and pooling, are inspired by the human brain. However, note that, nowadays, CNNs are mainly ...

Is there a rigorous proof that AGI is possible, at least, in theory?

I'm going to go out on a limb and suggest that this is a matter of evolution, that humans are in no way exceptional in the grand scheme, and that AGI will manifest so long as technology advances, ...

Is there any specific SW framework, libraries or algorithms designed for implementing a practical artificial general intelligence (AGI) system?

Not to my knowledge. The problem is that this is such an enormous task, it cannot really be tackled at once. So the obvious solution is to reduce the scope. In early AI people were using toy domains, ...
