I almost killed my phone again today. I didn’t realize that there are not just long, short screws in the phone. There are screws of different sizes: 0.12, 0.13, 0.16, and 0.17 mm just to replace the battery. I forgot how I killed my two iPhone 5S. But definitely, I didn’t know that there are…
The scene before and after I have already forgotten. I brought some people into my house. Somehow including Brad. This is the first time he appeared in my dream. The walls are full of bookcases, rather than like a home. It is more like an exhibition corner in a library. I almost led them to…
As I continue to explore options for using Zoom for teaching, one thing I like a lot is that I can connect my laptop to a monitor and only show one of the screens on Zoom. This way I can easily control what my students can see and I can leave some “cheat sheet” or…
The pipe behind the water heater broke during some very cold days. I don’t know how long the water was flooding out before I realize that stream was running out of the storage room. It took several weeks to fix it. I first considered looking for a plumber. But everyone seems to be so busy….
Tested Mynt Eye on my Thinkpad because it seems that it only supported up to 18.04. The sample example can run off the box as described here. However, it seems to need quite some work to get it run with OpenCV. Moreover, the depth estimation is not accurate at all. Not sure if further calibration…
I checked in a “hotel”? Again, I have rooms on several floors. I moved around and “forgot” to check out the other room as in some other cases. (Maybe related to my current situation with too many “offices”?) I tried to check out and came across Gordon. He is in a hurry and we entered…
Didn’t know the name ancestral sampling before. It is just sampling p(x,y,z) as p(x) p(y|x) p(z|x,y). Or basically, it is just a special case of Gibbs sampling.
It seems to be the last day of school. Or it is a farewell not going to meet again. I can’t remember anything before that. But at the last moment, I was both outdoor and in a classroom (it often happens in my dream with contradictory scenes). I think I am talking to YS. Saying…
Came across of this video explaining robust PCA. It came with a book and it looks okay. As PCA can be considered as decomposition of data matrix with the highest singular value. So what PCA is doing is simply low-rank matrix approximation of the data matrix. So robust PCA is a simple idea that tries…
Can’t recall where the last scene was. But I was traveling and shared a room with Kevin. He didn’t look happy as usual. I tried to break the silence with some small talk but didn’t manage to break the silence. There are two washers in the room. I have my clothes washed and just stacked…
