IMO the RNN is overkill of this problem, compared to a simple and elegant algorithm called &quot;$1 unistroke recognizer&quot;. That one works beautifully even when trained with just a single sample of each gesture.<p>I hope $1 unistroke gets more recognition because it can be integrated in an afternoon into any project to add gesture recognition and make the UI more friendly.<p>It works quite reliably for palm style &quot;Graffiti&quot; text entry, as long as each letter is just a single stroke. The original paper also makes great effort to be readable and understandable.<p><a href="https:&#x2F;&#x2F;depts.washington.edu&#x2F;acelab&#x2F;proj&#x2F;dollar&#x2F;index.html" rel="nofollow noreferrer">https:&#x2F;&#x2F;depts.washington.edu&#x2F;acelab&#x2F;proj&#x2F;dollar&#x2F;index.html</a>

&gt; However, if you’re anything like us, even a simple straight line drawn with a mouse or a trackpad can end up looking like a path trod by a tipsy squirrel. Don’t even get us started on circles and rectangles.<p>But who needs to draw shapes with their mouse in Canva? Years ago, Miro had a feature that converted your flailing attempts at drawing a star with a mouse into a geometrically precise star (or circle, or triangle, or whatever). I thought it was super cool, but then I never, ever needed to use it. I never need to do line drawing with my mouse: if I&#x27;m making diagrams, I just use pre-made shapes, which are faster. If I am making icons, I use a whole different process centered around Boolean operations and nudging points and the Pen tool—and I am probably using a dedicated program, like Illustrator, to do it. And if I am actually illustrating something (rarer these days than in times past) I have a tablet I will pull out. I am sure the tech here is cool, but what&#x27;s the use case?

The library Canva use for drawing lines may be of interest: <a href="https:&#x2F;&#x2F;github.com&#x2F;steveruizok&#x2F;perfect-freehand">https:&#x2F;&#x2F;github.com&#x2F;steveruizok&#x2F;perfect-freehand</a>

&quot;We developed a variation on the Ramer-Douglas-Peucker (RDP) algorithm, which is a curve simplification algorithm that reduces the number of points in a curve while preserving its important details. It achieves this by recursively removing points that deviate insignificantly from the simplified version of the curve.&quot;<p>This reminded me of an old side project, which others may be interested in. I applied Douglas-Peucker to Picasso for a talk at Strange Loop 2018:<p>Picasso&#x27;s Bulls: Deconstructing his design process with Python <a href="https:&#x2F;&#x2F;rrherr.github.io&#x2F;picasso&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;rrherr.github.io&#x2F;picasso&#x2F;</a>

This makes me wonder how they pulled off something similar in Macromedia Flash (RIP) well over 20 years ago. I vividly remember being amazed by how it smoothed out curves when drawing freehand, with such limited processing power compared to today&#x27;s CPUs.

Great article, and very interesting work.<p>I&#x27;m surely in the minority, but I oddly find myself enjoying the hand-drawn &quot;shaky scribble&quot; versions more than the &quot;sleek vector graphic.&quot; I&#x27;m sure even my preference would be context dependent though, so even in my case it&#x27;s a cool feature. But in a world of artificial perfection, there&#x27;s something innately attractive in a genuine hand-drawn production.

If you implement a feature like this, please, make it optional and obvious when it’s enabled. It’s maddening when tools try to be too smart and don’t get it perfect (I have been guilty of this too)

There was a game called Scribblenauts that my kids loved years before any of the recent ML&#x2F;AI hype and it was able to turn very rough scribbles into an amazing number of different objects. No idea how they did it, but even I was impressed - the kids thaught it was magic.<p><a href="https:&#x2F;&#x2F;store.steampowered.com&#x2F;app&#x2F;218680&#x2F;Scribblenauts_Unlimited&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;store.steampowered.com&#x2F;app&#x2F;218680&#x2F;Scribblenauts_Unli...</a>

It would be nice if this was open source :) Recently, there have been various models that have become small in size (This one is 250kb. There are other simple tasks that have seen models of size 50kb or so for finetuning large models). I am looking forward to when we can actually get back to small models for useful applications :)

A pentagram and a sparkly star are not the same thing. Is this an example of underfitting?

They trained it to recognize nine predefined shapes?<p>Come on, if you&#x27;re going to train a model, make it a generic smoother&#x2F;DWIM for drawing shapes!<p>You will also get more &quot;analog&quot;&#x2F;never-identical shapes, which will feel much more stylish in the way drums feel warmer than drum samples even when played by an expert at hitting the notes identically and on time.

There&#x27;s an odd feeling about the writing in this article. Maybe I&#x27;m seeing things but it does not feel like it&#x27;s written or composed entirely by a person.

followed the &quot;Draw&quot; link and played with the thing there, but didn&#x27;t see a way to demonstrate this functionality? Is it a paid feature or something?

if model is on client side itself why not make it open source?

The engineers of ASML, TSMC and others wake up every day, shoot lasers on liquid lead to generate light with extreme short wavelenghts, to make smaller and more performant chips.<p>And web developers wake up every day so that no one notices their work.
