I implemented the network from scratch in vanilla javascript. The file is just a custom binary file containing the names, shapes, and weights of the network parameters. If you have…

The dataset is from the IAM On-Line Handwriting Database. I've linked my github, which has my email, on my profile.

Outputs are sampled from a probability distribution, and increasing the legibility effectively concentrates probability density around more likely outcomes. So you're correct that …

Hey HN — This is a simple web app that allows you to enter text and watch as an in-browser neural network generates the corresponding handwriting in real time. I’m happy to hear fe…

The value is almost entirely as a technical demo of current machine learning techniques. Handwritten fonts will always be a more reliable way to create synthetic handwriting, so I …

Yes, it's mostly based on that. Primary difference is that this model adds an inference model (VAE style), which allows you to a) sample style vectors from a latent distribution b)…

It's not intentionally slowed down. The sampling process is computationally heavy and you'll notice improved performance when running it on better hardware. There are many algorith…

The model was trained on a relatively small dataset which has few occurrences of the letter x, almost none of which are in cursive. As you've found, asking the model to write out a…

Non-statistical methods of imitating handwriting are always fairly easy to identify as synthetic due to the uniformity of strokes and unnatural kerning (among other things). Even m…

This problem was more or less solved with neural networks in 2013, see https://arxiv.org/abs/1308.0850 . I've implemented a similar model in javascript that you can interact with: …
