I like productivity! So I've found the best #FFT size for #Wakegp. Some experiments about the #parsimonypressure method I have done shows effectiveness of my simple method. Now I'm experimenting on that to find out the sweet spot.

Regarding instructions, I already have done experiments. And the results were unexpected. Adding functions like Sine, Cosine, Logarithm and Square root have negative impact on fitness.

There are still a lot of parameters which I need to fine tune. Mutation rates, number of demes, tournment size, reproduction rate, crossover rate and a lot more. And I also need to experiment with #LexicaseSelection

After all these and when I have runs producing accurate enough programs, I should learn how to optimize the found programs to "summarize" them. I really hope compilers like #LLVM and #GCC already do so. I have doubts but I think most likely, they already have heuristics to summarize programs while keeping the logic.

God willing, when #repebble(the new #pebble #smartwatch) comes to market, I could try to see if I can use it there. Then #repebble would be the first industry application of my research.

Edit: Regarding the simple parsimony pressure method I invented, I'm pretty sure already someone has invented it but I haven't found it in the literature. Just like tons of other things I invent or discover in Math or CS and then realize it has already been discovered or invented.

I love #unixphilosophy

➜  runs5 git:(main) ✗ function f1() { wakegp -c /var/tmp/$1.toml > $1_$2; }
➜ runs5 git:(main) ✗ sleep 130m; for i in {0..64} ; do for j in 2k 1.2k 1.4k 1.5k 1k 1.6k 1.8k ; do f1 $j_800 $i; done; done

Scheduling #wakegp experiments with #sh so tomorrow I have experiments done and I can just do T tests in R.

Edit: I'm testing different #FFT sizes. If you are interested, see my current status here:

codeberg.org/farooqkz/wakegp/s

Edit2: So it's morning and I realized I had to do f1 $i $j_800...

Hallo #Düsseldorf! Im #FFT (Forum Freies Theater) gibt es noch bis morgen

ON/LIVE 2025
Free, open, always – Digitalisierung für alle?

Es geht um ein zentrales Versprechen der Digitalisierung: mehr Zugang für alle, jederzeit und überall.

Heute abend bin ich auch dort, zum Thema #DigitaleTeilhabe.

The Fourier Transform is a mathematical operation that transforms a function of time (or space) into a function of frequency. It decomposes a complex signal into its constituent sinusoidal components, each with a specific frequency, amplitude, and phase. This is particularly useful in many fields, such as signal processing, physics, and engineering, because it allows for analysing the frequency characteristics of signals. The Fourier Transform provides a bridge between the time and frequency domains, enabling the analysis and manipulation of signals in more intuitive and computationally efficient ways. The result of applying a Fourier Transform is often represented as a spectrum, showing how much of each frequency is present in the original signal.

\[\Large\boxed{\boxed{\widehat{f}(\xi) = \int_{-\infty}^{\infty} f(x)\ e^{-i 2\pi \xi x}\,\mathrm dx, \quad \forall\xi \in \mathbb{R}.}}\]

Inverse Fourier Transform:
\[\Large\boxed{\boxed{ f(x) = \int_{-\infty}^{\infty} \widehat f(\xi)\ e^{i 2 \pi \xi x}\,\mathrm d\xi,\quad \forall x \in \mathbb R.}}\]

The equation allows us to listen to mp3s today. Digital Music Couldn’t Exist Without the Fourier Transform: bit.ly/22kbNfi

Finally managed to get audio responsive working. The greatest challenge was settling on a frequency and a threshold.
