Re: What to do when your research is stuck?

If you are stuck, I think the best solution is to go outside for a walk to empty your mind. Then sometimes, when you come back you will have that "Eureka" moment. Sometimes it is just better to take a break. Doing some yoga, sports or listening to some calm music can also help to focus on ...

Re: In covid times, academic positions?

For me COVID has also decreased my productivity during the first year... I wasted quite a lot of time due to COVID, not just because getting sick but because of various administrative burden, lockdown etc. How about you guys?

Re: pattern mining in car trajectory data?

I think pattern mining is not so suitable for GPS data, but if you first apply some technique to divided a trajectory into point of interests, then these points of interests can be viewed as items, and then it should be possible to do pattern mining i think. Maybe like sequential pattern mining to f...

Re: Modify Prefixspan for video game data?

Unrelated to the topic, I found that the Java implementation of PrefixSpan in SPMF is really fast when I did some experiments a few months ago. I think it must have took quite many optimizations. I hope I can write the good code like that. I will roll up my sleeves and work harder :D

Re: Game playing artificial intelligence

It depends on the game. Different games, different models to play. For machine learning, some of the best models use renforcement learning but sometimes more simple approach can work better.

Re: Dealing with Image datasets

maybe doing some features extraction first would be a good idea and then use these features as items?
