Detexify is another one that's been around for many years (at least 5 at this point) and has saved me hours: <a href="http://detexify.kirelabs.org/classify.html" rel="nofollow">http://detexify.kirelabs.org/classify.html</a>
On a somewhat related note, does anyone have any particularly nice ways of writing math-related notes?<p>Part of me wants to just hand-write them and then maybe scan them, but that's not searchable/indexable, and doesn't lend itself well to version control.<p>Writing in TeX or LaTeX would make them searchable/indexable, but this seems a little heavyweight for just notes (like answers to exercises). I don't use TeX/LaTeX that often, so I feel like I'd be spending half of my mental energy figuring out how to format things, figuring out how to invoke the tools, what packages to install, etc.<p>Are there any nice solutions out there for this sort of thing?
It works quite well, but I wish there was a way to make small corrections (e.g. erase parts of my input).<p>The app keeps mistaking my handwritten "n" for "h", and my "k" for various obscure things like "|x:", and it's a bit of a pain to make small adjustments after most of the equation has been written: <a href="https://i.imgur.com/KneVGIU.png" rel="nofollow">https://i.imgur.com/KneVGIU.png</a>
Works like a charm on my Surface Pro 3. Incredibly impressed, One note doesn't recognize my handwriting well but this is incredible as a math undegrad !<p>As many have said, an open-source app would be a godsend.
Awesome! This project reminds me of something I worked on years ago: <a href="http://goo.gl/GKOxrg" rel="nofollow">http://goo.gl/GKOxrg</a>
Very neat. One problem is immediate: when I handwrite an "x" for maths, it is as two 'c's touching back-to-back, so as not to confuse with some multiplication/cross-product symbol; such input proves very confusing to this code.
I am building an Android (best with stylus) hand writing app...<p>Drawings can be viewed / shared via web
and are updated real-time (online whiteboard)<p>some samples:<p><a href="http://write-live.com/d/dba21681-8d3f-4fbe-8b4b-e5c1983df934" rel="nofollow">http://write-live.com/d/dba21681-8d3f-4fbe-8b4b-e5c1983df934</a><p><a href="http://docs.write-live.com/WriteliveServer/webview.html?d=2b81b4b1-af48-4a12-bab6-a7844eac91a5" rel="nofollow">http://docs.write-live.com/WriteliveServer/webview.html?d=2b...</a>
From what I can tell, it had a hard time distinguishing matrices from vectors. What I wanted was:<p><pre><code> [ 1 1 ]
[ 0 1 ]
</code></pre>
What I got was<p><pre><code> [ 11 ]
[ 01 ]</code></pre>
This would be quite a cool problem to attack using RNN. Perhaps using an attention-following mechanism like the one used for house numbers [1]. It's fairly well-defined. You would need a ton of example data though.<p>[1] <a href="http://arxiv.org/abs/1412.7755" rel="nofollow">http://arxiv.org/abs/1412.7755</a>
This is actually pretty impressive<p>Tried it out on a random equation from the Fourier transform wiki page:<p><a href="http://imgur.com/Ud9FNoA" rel="nofollow">http://imgur.com/Ud9FNoA</a>
LaTeX is super cool for mathematics and academic papers. For my book though I had to migrate off to InDesign because it was just much easier/quicker to get it to do what I wanted.
