Introduction
Starting a career in Artificial Intelligence (AI) requires familiarity with common industry terms and concepts. This AI glossary covers key topics in AI and machine learning, aiding in professional certifications, resume drafting, or job interviews. AI and Natural Language Processing (NLP) technologies are crucial for business operations but often complex.
To simplify discussions and ensure inclusivity, we’ve compiled an AI and NL-specific glossary.
