[11:58] zabulskyi : yes
[11:58] toliageo - Tolias Georgios : Link to the slides: http://cmp.felk.cvut.cz/~toliageo/rg/papers/slides/superglue_slides.pdf
[12:01] spetlrad : BBB has this function that you may upload the presentation to the server and then you don't need to share your screen...
[12:01] toliageo - Tolias Georgios : sharing screen is still useful to switch to the paper if needed.
[12:02] spetlrad : as you wish - just wanted to note the feature since it (supposedly) saves bandwidth
[12:05] spetlrad : (and, of course, it is maybe the only reason why to use the BBB, since a Google meeting may be made public...)
[12:05] svobodat : BBB could be also public, no problem
[12:05] toliageo - Tolias Georgios : current meeting is also public - not restricted to CTU
[12:11] Antonín Vobecký : Why don't the probabilities sum up to one?
[12:12] mishkdmy : @spetlrad -- I have recently given a presentation in MS Teams and was explicitly asked not to use this "upload" feature because of bigger lags and loss of sync for some users
[12:12] spetlrad : @mishkdmy OK, so then no reason to use the BBB :D
[12:12] spetlrad : terrible software
[12:16] Michal Polic : I see still page 3 of the presentation. BBB is really great program.
[12:16] spetlrad : I also see the third page, we moved to another?
[12:17] navara : You see page numbers? I don't/
[12:17] spetlrad : well :D what do you see? I see "problem formulation"
[12:18] navara : No.Attentional Graph...
[12:18] spetlrad : damn
[12:19] spetlrad : @michal polic 
logout & login helps
[12:19] Michal Polic : yes, I see, it is good now
[12:25] svobodat : Just a reminder for effective use of BBB. When presentation is uploaded, people can draw/point on the presentation - it often help when discussing a particular problem. I
[12:27] Jiri Matas : my mike is not connected ....
[12:27] toliageo - Tolias Georgios : (i think) this is done in the very first step when you connect to the meeting
[12:27] Torsten Sattler : I seem also not be to heard
[12:28] Jiri Matas : The L layers are more like steps of an algorithm. Plus why not draw this as recurrent net?
[12:28] Torsten Sattler : about the previous slide: Is l an iteration number? Or a layer number? What I find confusing is that there is the word MLP on the slide, which implies multiple layers
[12:28] abenbihi : @Jiri Matas, This is not a recurrent net because the weights are different for each l
[12:29] Jiri Matas : thanks, that answers the question
[12:30] Jiri Matas : I am trying to figure out how to do something about my "mute" mode
[12:30] spetlrad : @jiri matas - reconnect "with microphone", you probably connected only in the "listening" mode
[12:31] zabulskyi : @jiri matas -- the icon next to you tells that you are connected  "with microphone"
[12:33] Jiri Matas : I am connected with microphone, but nobody hears me..... the icon is green, not muted ....
[12:33] abenbihi : @Torsten Sattler, yes l in an iteration number. you can see it as the descriptor for keypoint i at layer l is updated by x_i^{l+1} = MLP_l(x_i + attention(x_i, other descriptors either in the same img (self-attention), or in the other image(cross-attention)
[12:34] abenbihi : my bad, it is x_i + MLP_l(attention(x_i, other descriptors either in the same img (self-attention), or in the other image(cross-attention))
[12:38] toliageo - Tolias Georgios : Invitation link for CTU users of brute: https://cw.felk.cvut.cz/brute/bbb.php?join=cw_34Jycyoxnw  junk in case it solves any mic problems
[12:39] rozumden : does the network have to be trained separately for different descriptors (SIFT, HardNet)?
[12:39] mishkdmy : @rozumen - yes
[12:41] spetlrad : ad Keypoint encoder: Is it common to construct features by summing a descriptor and MLP(position)? (2) in paper. They argue that it "enables the graph network to later reason about both appearance and position jointly" - does it make sense? These are like two "modalities"...
[12:44] mishkdmy : @spetlik - kind of. It was first done in the ContextDesc  https://arxiv.org/abs/1904.04084
[12:44] spetlrad : @mishkdmy hmm, interesting. thanks...
[12:45] abenbihi : @Tolias, I think this is a way to say that you assign each keypoint to at most one keypoint
[12:48] toliageo - Tolias Georgios : this is not enforced in the matching layer (not with Sinkhorn) - only with the loss
[13:16] Torsten Sattler : Can we change to some other software the next time? My microphone, even after reloading the website, does not seem to work.
[13:16] Torsten Sattler : Why not go for Google Meet as before?
[13:17] toliageo - Tolias Georgios : let me comment that at the end - the BBB apparently  failed
[13:17] toliageo - Tolias Georgios : BBB experiment*
[13:18] spetlrad : <3
[13:22] svobodat : For people struggling with mic. Did you allow access  for the bbb server - can be checked - mic icon at the URL line?
[13:23] Torsten Sattler : Yes, of course
[13:36] spetlrad : I got disconnected for a while - did we find the "true contribution"?
[13:37] navara : I do not have this impression.
[13:37] matas : I think the mic problems has to do with something I pressed when connecting.  The misleading and problematic thing is that your audio is connected and it isn't
[13:38] mishkdmy : agree, we haven't find it. We would need  to compare w.r.t the other papers on the similar topic to do it
[13:38] kangchen : set your browser's language as the default, I think
[13:38] spetlrad : ok
[13:38] spetlrad : * @mishkdmy
[13:39] Torsten Sattler : I am trying, but it is not working
[13:39] Torsten Sattler : My audio worked and the audio test worked
[13:50] spetlrad : MS Teams forces me to "live in it" and that is terrible, I don't want to have Teams constantly opened to not miss something...
[13:51] spetlrad : + if you have more MS accounts (like I do), another problem
[13:52] mishkdmy : @spetlrad - why live? just join for the videocall
[13:52] spetlrad : for me, it was always "trying to find the join button" uh oh, where is the correct channel ...
[13:53] mishkdmy : I mean "join by clicking on the web link"
[13:53] spetlrad : with which account? ... I mean if you don't live in it, you get lost :)
[13:53] spetlrad : maybe, I always had to join in some channel...
