Thank you for the amazing video ! I'm planning to use FCA to create concept heirarchies and this was a great primer on the subject coming from a non-mathematical background ! Cheers
Hello! Thank you so much for the video. Please clarify one moment: Is it mistake in 1st Concept Lattice? There is [ (Bo,Fa,Ti) (HDMI) ]. But should be [ (Ch,Fa,Ti) (HDMI) ] instead. Respectively, down in lattice: should be [ (Ch) (CD, HDMI, bio) ]. Pls, correct me if I'm wrong.
Amazing thank you very much ! just a little question your animations are really nice and smooth, how do you manage to do that ? is it a particular software or clever use of powerpoint + editing software or others ?
This feels interesting in theoretical circumstances, but I feel like it might need to be adapted in practical examples like the laptop one? With subjective reviews like this, I feel like having one "incorrect" review that overvalued or undervalued a laptop might change the results - real data is noisy and the mathematical rigor of this theory might be less suited to the problem than a more flexible neural network or genetic model. Worth looking into, though.
Nice introduction to a topic I had never heard of before 🙂👍 And I really appreciate the laptop names. I figured out 3 of them ... please no spoilers, but are they all puns? 😅
I'm happy you liked it! Yes, the laptop names are all references to real computers. Not always proper puns, though. In the first draft I also used altered company names which made it a bit more obvious. But they took away to much space. You can stoll see a few in the very first few seconds when the computer magazine is open.
Hi! I found your explanation EXTREMELY enlighightening, been searching for such thing for many years. Can you please direct me to more literature/sources? (besides Ganter 1998)
I'm happy that you like it! I don't know too much beyond the basics, I'm afraid. But: A good jumping-off point is the book "Formal Concept Analysis - Foundations and Applications" edited by Ganter, Stumme and Wille. It gives a glimpse of how FCA can be used in Algebraic Geometry, Linguistics, Software Engineering etc. There's also the (yearly?) International Conference of Formal Concept Analysis. Its proceedings are a treasure trove of information, but it focusses more on the theoretical aspects AFAIK. Lastly, if you are interested in a concrete application: It's a good idea is to google Formal Concept Analysis plus the specific thing. E.g. "Formal Concept Analysis molecular structure".
Unfortunately not, I'm afraid. It has been a while since I actively used FCA. In the past, I used conexp.sourceforge.net, but it was rather slow for larger datasets. But I'm not up-to-date with the most current algorithms.
Das Video hat mir sehr gefallen. Gerne mehr! :)
Vielen Dank! 🙏
Hatte mir mal eingebildet, vor Ende des Jahres noch eins zu schaffen. Aber mal schaun... 😅

Yeah, you're right. Very weird... Guess I shuffled a few rows around late in the production of the video and didn't update the labels...
@@sumandproduct Got it, thank you!

Thank you! All animations are made with cindyjs.org/ . Since it isn't designed as an animation tool, I do lots of custom code as well, though.
Could you provide a detailed proof (or reference) for properties of derivation operation provided in video?
The book "Formal Concept Analysis" by Bernhard Ganter and Rudolf Wille sounds contain everything you need.
Do you know if this tool has been used for autoomatic text summarization techniques. It could probably be useful for it?
I know that FCA is used in computational linguistics. But I'm unfortunately not experienced enough to know for what exactly.

Oh, yes, this is pretty much a toy example. I assume that you can somehow "trust" the experts.

@@sumandproduct Yeah I saw the company names just after commenting ... the YT autoplay tried to hide it from me :D

Thank you for this video, can you direct me to the most efficient FCA software.
Unfortunately not, I'm afraid. It has been a while since I actively used FCA. In the past, I used conexp.sourceforge.net, but it was rather slow for larger datasets. But I'm not up-to-date with the most current algorithms.
