Proposal: Artificial Intelligence
There is already a site about machine learning named Cross Validated. How is this proposal different?
First of all, artificial intelligence is a much broader term than machine learning. While at the same time Cross Validated is not about machine learning, but about statistics (while machine learning is a field in the intersection of computer science and statistics).
Examples of questions that are no fit for CV:
Cross-Validation: "Cross Validated is a question and answer site for statisticians, data analysts, data miners and data visualization experts"
I somehow do not feel the relation very strongly. The only point it really is a crossover on it the word 'data'.
I will however take your word for the topic of machine learning being prominent on 'Cross-Validation', but to that I would point out, as Lejlot did before, That Machine Learning is a single aspect relating to Artificial Intelligence.
In addition to learning algorithms (On which Machine learning strongly relates) the field of AI reaches into Neural Networks, Control Systems (And theory), Cybernetics, and probably a few other fields I can't think of at the moment. also Swarm Intelligence is pretty much the same as AI but (most of the time) in a different 'format', so I am under the assumption this proposal would also cover research relating to Swarm Intelligence.
That is why this proposal is different.
Cross validated is about data analysis. While artificial intelligence can include a good deal of this, it is a different field. Machine learning is different for two main reasons:
As many other people have already said, machine learning and artificial intelligence is much broader. A neural network wouldn't be exactly on topic in cross validated, however it would be the purpose for this site. Also, while machine learning includes a great deal of data analysis, artificial intelligence also pertains to natural language processing, robotics, understanding images, and anything else that are features of an intelligent being, while data analysis
Artificial Intelligence often has a different objective than data analysis. Creating code that gets better at something is different than interpreting information, even if sometimes, in practice, similar tasks are being performed.
