Explain linear regression and Transformer fundamentals

Last updated: Mar 29, 2026

Quick Overview

This question evaluates core competencies in statistical modeling and deep learning architecture, specifically linear regression (optimization objective, estimation and interpretability under common failure modes) and Transformer fundamentals (self-attention mechanics, positional encodings, multi-head computation and long-sequence scaling trade-offs). It is commonly asked in Machine Learning interviews for Data Scientist roles to probe foundational understanding of modeling assumptions, probabilistic interpretation, model interpretability and algorithmic complexity; domain: Machine Learning; level: primarily conceptual understanding with practical-application reasoning.
