Using k-fold cross-validation has proven useful to find label issues in our dataset. I write a little bit about it here tlbvr.com/blog/k-fold-...

Does "reporting junk" do anything on iMessage? My phone number probably hung out in dark places and now i'm flooded with spam. Keep reporting but I don't feel like it does anything.

Lowering the loss of your model feels like a game. You initially take bets and get rewarded (maybe).

Converting pip groups from pyproject to requirements.txt is sometimes necessary to interop with tooling that don't have pip>=25 or some automation picking up on requirements.txt. I've been using a script provided by the python docs that does just that.

Coming from a serious Typescript and other typed languages background, I was a bit worried working in python but I'm pleasantly surprised about the ecosystem revolving around types. Finding separate type stubs reminds me of the early TS days where most libraries required custom .d.ts files.

I'm looking into ways of spotting labels issues in my training data. Cleanlab github.com/cleanlab/cle... has a feature where you feed predictions and it'll tell you which image may have a bad label based on the confidence of the predictions.
GitHub - cleanlab/cleanlab: Cleanlab's open-source library is the standard data-centric AI package for data quality and machine learning with messy, real-world data and labels.

I'm going to go back to Motherland belgium for a couple of days. I'm looking at surprising my dad in a nice restaurant. I haven't been to belgium in a long time so I don't know what's good. If anyone knows any recos in the Mons region, send them my way!
