What artificial intelligence strategies are useful for summarization?

The following post has a bit of math, which I hope helps to explain the problem better. Unfortunately it seems, this SE site does not support LaTex: Document summarization is very much an open ...

What approach should I use to detect faces in video game footage?

At first, you can find lots of information as pedestrian detection. As you are trying to localize game characters, the face is not the best option. You need to look for the character in general. ...

What would the commercial application of a conscious AI look like/be?

They may be just for fun. If you had a robot that understood you, could hold a conversation with you about your interests, and even had goals of its own (good or bad), it wouldn't really need to do ...

Which machine learning algorithm can be used to identify patterns in a dataset of the cache performance of a CPU?

You're basically looking for is unsupervised learning (UL). There are a lot of UL techniques around, but I'm not sure you'll find one that does exactly what you want with no user input at all. Still, ...

Will training an AI still work if the input data is somewhat sparse?

First, the title mentions "sparse data". Recently the expression has taken a clear meaning: The agent input is data with mostly zeros. In the question a different meaning: A "sparse data stream", ...
