ML Fundamentals
XGBoost
A powerful, fast machine learning algorithm that wins most competitions on tabular data, the workhorse of structured data ML.
Definition
An optimized gradient boosting library that builds an ensemble of decision trees sequentially, with each tree correcting the errors of the previous ones. Known for speed, performance, and handling of missing data.
Why it matters
The most successful algorithm for tabular/structured data in production, often outperforms deep learning on spreadsheet-style data.

The "switch" inside a neural network that decides whether a neuron should fire, allowing the AI to learn complex non-linear patterns.
Active Learning
A technique where the AI asks humans to label only the most confusing examples, saving time and money on data labeling.
Anomaly Detection
Finding the "weird" stuff in a dataset, like a credit card charge in a foreign country or a broken machine part.
Artificial General Intelligence (AGI)
