Explain ML model fundamentals

Q: Explain ML model fundamentals

This question evaluates understanding of core machine learning concepts and competencies, covering probabilistic classifiers (logistic regression, Naive Bayes), transformer architecture and self-attention, ensemble strategies (bagging vs boosting), and multi-class evaluation metrics within the ML system design domain.

Q: How do I approach ML System Design interview questions?

ML System Design questions require understanding of core concepts and practice. PracHub provides solutions with explanations to help you master ml system design interviews.

Question

Comprehensive ML Concepts: Logistic Regression, Naive Bayes, Transformers, Multi-class Metrics, Bagging vs Boosting

Context

You are interviewing for a Machine Learning Engineer role. Answer the following conceptual and practical questions clearly and concisely.

Questions

Logistic Regression
- Explain the core principles and statistical assumptions behind logistic regression.
Naive Bayes
- How does Naive Bayes work? When and why does it perform well?
Transformer Architecture
- Describe the transformer architecture. Why does self-attention help?
Multi-class Evaluation Metrics
- What metrics would you use to evaluate a multi-class classification model and why? Briefly compare their use cases.
Bagging vs. Boosting
- Compare bagging and boosting. How do they reduce error (bias/variance), and what are the trade-offs?
