Hiho :-) I have a super general question and want to prevent to get downvoted / closed immediately. I have no experience with smart home stuff: I am confused about the choice of vendors.

I want to add a couple of different connected lights (mostly LED stripes). I play with the idea to buy stripes from LIDL / IKEA / Govee, plus additionally maybe a single Philipps Hue light bulb. My goal is to get 3 "scenes":

* 6am - 8am "wake up": Starting with a low brightness / 2700K up to maximum brightness + daylight (6000K or higher)

@ConorMancone I love your answer here :-) This is what I hoped for when I asked the question :-)

Martin Thoma

Sep 15, 2020 18:55

@ConorMancone Sorry, I didn't formulate it correctly. I've seen that the question was closed as off-topic, because the question is (according to the closing reason) not about IT security. I strongly disagree with that.

"You never implemented back-propagation" - wrong. It's about 7 years ago, but I did implement it.

Martin Thoma

Nov 14, 2018 22:26

@nbro No, you are wrong. I have (a) understanding of the process (b) a high-quality reference that agrees with my statement. If you don't come with something of similar quality, I will not discuss this further with you.

@DavidCarlisle After removing \usepackage{parskip} the problem seems to be gone.

Martin Thoma

Sep 27, 2017 09:19

I'm currently trying to make a minimal example. The document is quite big and that takes quite a while, but I think I found it: It was not related to the glossary (I'm not sure if that was anther problem or what happened there). A big minipage after the sections seems to cause that behaviour.

Martin Thoma

Sep 27, 2017 09:12

I have a question for which I'm not sure how to phrase it: When I add `\printglossaries` to my document, it changes something so that the sections look different. Before, if I have multiple sections below each other (nothing in between) they are close together. After adding `\printglossaries` there is a lot of space.

Any idea where I have to look for the problem?

Short question (for which I'm not too sure if it would fit on tex.SE): Why does the tool "academic-writing-check" give the warning:

"... and HSI.<add a \@> Reasons for ...."

What does \@ do and when should it be used?

Dec 11, 2015 09:48

@DavidCarlisle I guess it depends on the bibliography style I use? Is there any standard/common "save" field to use which will not get displayed?

Do you think I should ask such a broad question? (I wouldn't care if we made the question / answers community wiki)

moose

Dec 11, 2015 09:08

I've got a short question: I would like to start a question on TeX.SE like "How are / should BibTeX fields be used?". The answers can explain any BibTeX field (e.g. "comment", "title", "review", "owner", "file", ...).

The question would be very broad, hence I hesitate to ask it like this. My real question is "Is 'comment' used in the created PDF output or is it just for me to organize my literature?". But I really would like to make the question broader as I came across this type of question a couple of times.

I guess the tanh restriction is because you have tanh as the activation function of your output layer?

You could interpret the complex points as R^2 (hence two floats as features). Does that solve your problem?

Jul 12, 2016 14:14

@PeterK. Thank you! Nice answer! (Because of the notation: I am learning about the Kalman filter in 3 different lectures simultaneously. To make things worse, I can only learn from the slides as I can only attend one of the three lectures. All lecturers use different, but similar notation. So I chose to take a mixture of the notations which I could remember best. As I don't know which textbooks are well-known in this area with typical notation, I chose to take the notation I am used to.)

Martin Thoma

Jul 12, 2016 13:53

> The system model you use in the link does not include a $G$ matrix. The question you are asking assumes the system model uses a $G$ matrix. Is that not a point of confusion?

Ah, yes, you're right. I missed that. It is actually in the slides. Thank you! Now I think I could answer the real question myself. (But the second part of your answer is what I was looking for. I only couldn't phrase it properly as I missed that the state equations were different)

Martin Thoma

Jul 12, 2016 13:19

@PeterK. My state equation and my measurment equation are the same as eq. 4.1 and eq. 4.2 from cs.unc.edu/~tracker/media/pdf/SIGGRAPH2001_CoursePack_08.pdf . The covariance prediction is the same as in (4.10). There is no missunderstanding on my side (or at least not only on my side) how to model the system.

Martin Thoma

Jul 12, 2016 13:19

@PeterK. What I named $C_k^{(r_s)}$ is named $Q$ by greg.czerniak.info/guides/kalman1 (and probably other sources, too). I just think $C_k^{(r_s)}$ ($C$ for covariance, $k$ for the $k$-th step, $r_s$ for "random" and "system") makes more sense.

Martin Thoma

Jul 12, 2016 13:19

Obviously, $Q$ and $G$ are matrices. I could also add which shape they have to have, but I guess that doesn't help.

Martin Thoma

Jul 12, 2016 13:19

I've added an explanation for $C_k^{(r_s)}$. For $Q$ and $G$ I can't add one, because I don't know it. I hoped that somebody would be familiar with this notation, as the Kalman filter is pretty well-known and somebody might have seen this notation before.
