Feature Engineering "biến hóa" dữ liệu thô thành "siêu năng lực" cho AI/ML!

Đây là quá trình tạo ra các features (đặc trưng) mới, giá trị hơn từ dữ liệu sẵn có, giúp mô hình học tốt hơn.

@data @datadon 🧵

How to assess a statistical model?
How to choose between variables?

Pearson's #correlation is irrelevant if you suspect that the relationship is not a straight line.

If monotonic relationship:
"#Spearman’s rho is particularly useful for small samples where weak correlations are expected, as it can detect subtle monotonic trends." It is "widespread across disciplines where the measurement precision is not guaranteed".
"#Kendall’s Tau-b is less affected [than Spearman’s rho] by outliers in the data, making it a robust option for datasets with extreme values."

Enteric Fermentation in 2022

Livestock digestion emits too much methane:
* Too many bovines in India, Pakistan, Brazil, United States, China;
* Too many sheep and pigs in China.

(The bubble sizes depend on the amount of methane sent in 2022.)

@amcasari it arrived! Preface starts strongly!

I’ll toot comments at #FeatureEngineering so as not to annoy you.

I am holding (on my knee) the book "Feature Engineering for Machine Learning" by Alice Zheng and Amanda Casari. The book features an illustration of an owl on the cover.

Anyone hoping for an immediately useful book about this new direction is going to be disappointed by Alice and my corny jokes and pragmatic approach to statistical inference.

I'm beyond excited to finally announce my new book "Feature Engineering A-Z" 🎉

The vision for the book is to be a comprehensive collection of feature engineering methods. Describing how they work, when and why you should and shouldn't use it. Code snippets in both R and Python!

I have been working on this project over the last couple of years. Please read it if this interests you! Always looking for feedback!
