So...I kinda started a huge project and it requires a pattern recognition for the users' schedules as the cherry on top.

I have no idea from where could I start learning this. I tried lots of stuff, I have basic knowledge of ai, but I need to get to the next level.

Any advice?

If you dont know ai deeply, you should get a job in google to do this
Or start from scratch after learning more.

Pattern recognition can be in two ways. One is a simple identification of a preset instance of an object. That's easy enough and requires little to no real AI aspects.

The other is the ability for the program to actively recognise new patterns as new ones, learn them and recall them when they need to. If this is what you want to do, and you need to look for advice on DevRant on where to begin learning about AIs, I recommend you don't attempt this project.

There may be lots of AIs coming out nowadays but they aren't made by people new to the concepts. They are made by large teams consisting of experts on the topic who know what they have to do.

I don't recommend you give up entirely but slow down a bit. You can't build a house if you don't know what dead loads are. You can't build a ship if you don't know what buoyancy is.

Start small, learn these concepts little by little and one day, when you do have the expertise to do so, build your floating house.
