Google just released LangExtract: Open-source. Free. Better than $100K enterprise tools.
Here’s what it does: 🧵
What it does:
→ Extracts structured data from messy text
→ Grounds every field to the exact source location
→ Handles 100+ page docs
→ Generates interactive HTML for verification
→ Works with Gemini + local models
What it replaces:
→ Regex/fragile parsing
→ Custom NER pipelines
→ Expensive extraction APIs
→ Manual data entry
Understanding regression models is essential in data science.
In 4 minutes, I'll demolish your confusion. Let's go:
1. The 6 Diagnostic Checks Every Data Scientist Should Run
Once you've built a regression model, your job isn't done. These 6 checks will tell you whether your model can actually be trusted.
2. Posterior Predictive Check
Ask yourself: do the model-predicted lines resemble the observed data line? If your model is a good fit, simulated data from it should look similar to your actual data. When they diverge wildly, your model is missing something important.
