When you have 50 expensive nanoparticle spectra instead of 50,000 cat photos, what do you do?
Suddenly understanding distributions and uncertainty quantification isn't optional. Math matters in scientific machine learning.

How do you store and process spectrum data?
I need to store, process and display spectra for a demo.
Curious what software others use.

Just wrapped a organization's first ML project. Key insight: AI readiness isn't about the tech.
It's about:
π Data-driven decisions
π Systematic evaluation
π§ͺ Experimentation culture
β‘ Speed infrastructure
Master these before AI arrives. Your competitors are waiting. Don't.
Nice Andreas. Do you have plans to start a study with the device? How would that look like?

From data mining to experiment mining.
2 weeks into studying analytical chemistry, I want to make a prediction.
In 5 years we will not talk about just "models" but about dedicated (equipment + machine learning) experiments.
We will not mine data, but chemistry itself.

I'm wondering too... so what did you build in those 4 months, using Deepseek?
π§ͺ TIL: Protein crystals mess with uv/vis.
Crystals scatter light, bend it, reflect it - and distort your spectroscopy data.
But here's the cool part: @ncaramel.bsky.social built a Python toolbox that automatically corrects for all the optical shenanigans.
