iverjo | 5 years ago | on: Python Pip 20.3 Released with new resolver

Sadly, pip 20.3 seems to have broken docker builds in one of my projects. The symptom is that the pip install seems to hang indefinitely (>40000 seconds). I switched back to 20.2 for now.

Thanks! No, it doesn't, but I'm happy to accept a pull request for such an option

iverjo | 6 years ago | on: Tiler: Build Images with Images

Shameless plug: Here's my take on building images with images. It uses a genetic algorithm. https://github.com/iver56/emoji-art-generator

Further, you could shave off a couple of bytes by inserting

  <body onload=F()>

before the canvas element, instead of having

  <script>F()</script>

after the canvas element

I think you could shave off 8 characters by doing

  0|Math.random()*3

instead of

  parseInt(Math.random()*3)

I also had that idea, and I made a crude proof of concept: https://github.com/iver56/cnn-clock

iverjo | 8 years ago | on: I made a talking emoji using regular emojis and JavaScript

This idea originated in the jsgolf community and dwitter (a site where you post 140 character js snippets that generate interesting visuals). See https://www.dwitter.net/u/aemkei

iverjo | 8 years ago | on: Ask HN: How much of your time do you actually spend coding?

I spend almost all time programming and thinking. Occasionally, I discuss some issues with colleagues. Other than that, I attend approximately one hour of meetings per week in total. I like this hands-off kind of management.

A friend of mine once wrote a 3D effect in a 2D canvas in only 130 bytes of JavaScript code: https://www.dwitter.net/d/914

Sony has been working on style (genre) transfer in music lately: https://youtu.be/I9M8l2guPSo?t=21m30s

Probably to avoid confusion, as git (and github) already had a concept of tags

Do you mean messages sent over infrasound (less than ~20 Hz)? That would typically not work, because most speakers cannot produce infrasound and most microphones don't pick up frequencies that low

iverjo | 9 years ago | on: Audio texture synthesis and style transfer

This is very cool! Kudos to the authors. I had the idea about this about a year ago (when style transfer for images was gaining traction), and wanted to do it in my master's thesis. I ended up doing something related, though: Evolving neural networks that transform sounds with the help of audio effects. For example, they can process white noise so it sounds like a drum loop. Sounds are available here:

How does this relate to Progressive Neural Networks [0]? That technique is also about accumulating knowledge (while not forgetting existing knowledge)

Jokingly, this was the first apple AI research I saw online, about a month ago: https://arxiv.org/abs/1610.08120v1

iverjo | 9 years ago | on: Finding the genre of a song with Deep Learning

To the author: Have you tried to use a logarithmic frequency scale in the spectrogram? [1] That representation is closer to the way humans perceive sound, and gives you finer resolution in the lower frequencies. [2] If you want to make your representation even closer to the human's perception, take a look at Google's CARFAC research. [3] Basically, they model the ear. I've prepared a Python utility for converting sound to Neural Activity Pattern (resembles a spectrogram when you plot it) here: https://github.com/iver56/carfac/tree/master/util

Nice approach, and well explained! By the way, Niland is a startup that also does music labeling with the help of deep learning.

Demo available here: http://demo.niland.io/

For example, it can output Drum Machine: 87%, House: 88%, Female Voice: 55%, Groovy: 93%

It's also inspiring to see how much you can do with only 140 characters of code (so it fits in a tweet). Here are some examples:

iverjo | 9 years ago | on: Show HN: Reorganize pixels of a painting into a smooth color palette using PCA

I recommend you to try the LAB color space and to use delta E 94 [1] for computing distances between colors in the color space
