I'm Esther, working in insurance. No, it's not as boring as it sounds. I just moved here from the "other place" to have more in-depth conversations about AI Ethics, Data Privacy and the joy and pain of training Small LLMs without a huge tech stack.

Excited to learnfrom the #Sigmoid Community and connect with humans, not bots.

Hallo Fediverse! Ich freue mich auf den Austausch zu KI-Ethik, Governance und allem, was Tech besser macht.

I really like darktable 5.4. Wayland support works very nicely. Small improvements like higher contrast module toggles to know what's turned on or off, is helpful.

Great work devs!

I think (for now) I'll continue to use Sigmoid and Filmic RGB tone mappers.

AgX shows real promise, and I'll certainly give it another try with the next update. Just can't get any satisfaction with the skies.

I’m MetaDarko, just moved here from mastodon.uno.
I share music, stories, and the little projects I’m working on.

Thanks for the welcome I’m looking forward to chatting with everyone! 😀

Logistic regression may be used for classification.

In order to preserve the convex nature for the loss function, a log-loss cost function has been designed for logistic regression. This cost function extremes at labels True and False.

The gradient for the loss function of logistic regression comes out to have the same form of terms as the gradient for the Least Squared Error.

I'm still experimenting with #sigmoid in #darktable to achieve a more #AnaloguePhotography look and feel. This was taken in September 2020 at #ExtinctionRebellion in #London I think it works quite well #photo #photography

michael Jun 17, 2025

I'm sure lots of #photographers out there use #darktable what do people think? Can you get the results you want? Do you have a favourite workflow? I used #sigmoid to process this #photo but i normally use #filmic I also used #ColorLookUpTable to apply #FujiVelviaEmulation It gives it a very #analogue feel, but sometimes when you look at things too long it becomes really hard to tell what is too much. I think I quite like it, but maybe tomorrow I'll be less sure.

Failure to have a $(HotTopic) strategy is bad for shareholder value, so having a strategy must be good.

@retrohondajunki @eaton @reconbot True. On an instance to instance basis, I'd especially prefer a larger limit like 4096 characters on #sigmoid because it feels like a kind of community where long-form capacity would be very useful (give the actual abstract of a paper and discuss it a bit instead of just sharing a link, etc.). In general I just wish that the longer form were more normalized to normalize occasionally delving deeper and longer into stuff.
