If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."

However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …

[D] Regression output range, [-1, 1]or[0, 1] vs [-inf, inf] • r/MachineLearning

#artificialintelligenceNov-12-2017, 12:50:31 GMT

Currently I'm trying to solve regression problem with deep neural network. I have some problems and I couldn't find appropriate answers from google so I'm here to ask your ideas. My data samples are in [0, 1]N. Because of this range, I had to use sigmoid(or tanh) as activation of output layer(Other layer's activations are all ReLU). However this cause serious problem which is gradient vanishing.
