Kurs Hakkında
Large Language Models (LLM) ve Text Processing
1 | Purpose & Industry Rationale
-
Market Momentum The global Natural Language Processing (NLP) market, valued at USD 25.9 billion in 2023, is projected to reach USD 189.6 billion by 2030, reflecting a 32.5 % CAGR.
-
Talent Surge LinkedIn’s Future of Work report shows that AI/ML job postings grew 38 % between 2020 and 2024, while positions requiring generative-AI and LLM skills expanded exponentially over the same period.
-
Salary Premiums As of 2025, U.S. LLM Engineer roles command average annual salaries of USD 180 000 – 240 000, with senior positions exceeding this range.
This certification provides a quantitative, globally verifiable credential for professionals who can transform raw text into rich representations, design advanced LLM solutions, and deploy them into production.

3 | Assessed Competency Domains
(each row contains a representative stem drawn from the uploaded item bank)
| Domain | Example Stem |
|---|---|
| Text Cleaning & Tokenization | “What is the principal difference between BPE and WordPiece?” |
| Vectorization & Embedding Spaces | “In which scenarios is cosine similarity preferred over Euclidean distance?” |
| Transformers & Attention Mechanisms | “Why is the d<sub>k</sub> scaling factor required in Scaled-Dot-Product Attention?” |
| LLM Architecture & Scaling Laws | “What is the practical implication of the Chinchilla scaling law?” |
| Prompt Design & Engineering | “How do zero-shot, few-shot, and chain-of-thought prompting differ?” |
| Fine-Tuning & Adaptation (FT, LoRA, PEFT) | “Why are LoRA layers favoured over full back-propagation in certain settings?” |
| RAG & Vector Databases | “Under what circumstances do dense and sparse retrievers achieve similar performance?” |
| Evaluation Metrics | “List advantages and drawbacks of BERTScore relative to ROUGE-L.” |
| Ethics, Safety & Hallucination | “Which vulnerability is uncovered by prompt-based jailbreak tests?” |
Questions target the Apply–Analyze levels of Bloom’s taxonomy; pilot testing produced Cronbach’s α = 0.83, indicating high reliability.
