Welcome!! Hey, we were ALL newbies at one time on another and it's nothing to be worried about. Consider it a "rite of passage' so to speak.
There are, as I'm sure you're aware, many facets of and many avenues to explore in the world of AI. It can go from language and speech processing, SR, conversational design, fetching / pattern matching, logic processing, knowledge retrieval, neural nets and oh so many other branches including toys, prosthetics, robotics and even social, government, military and practically every other industry on the planet.
At first, I'd recommend using the K.I.S.S. principle then let the doors of your personal discovery open as and where they may.
Feel free to "bounce" ideas off any of the members here. Who knows, you might actually get a decent answer!
Seriously, don't be a stranger...participate in the discussions and let us in on your projects or thoughts of projects.
A lot of times that particular "wheel" you're trying to invent, might have already been fashioned!
Glad to have you on board!!
