πŸš€ Generative AI Interview Questions with Answers (Part 3)

1️⃣1️⃣ What is a Context Window in an LLM?

πŸ‘‰ A context window is the amount of input and output text (measured in tokens) that an LLM can consider within a single interaction.

Example:

User Prompt
↓
Context Window
↓
LLM
↓
Response


πŸ’‘ A larger context window allows a model to work with more text, such as long documents or conversations.

---

1️⃣2️⃣ What is Temperature in Generative AI?

πŸ‘‰ Temperature is a parameter that controls the randomness of a model's output.

πŸ”Ή Lower Temperature β†’ More predictable output
πŸ”Ή Higher Temperature β†’ More varied output

Example:

Low Temperature  β†’ More consistent
High Temperature β†’ More creative


πŸ’‘ The ideal value depends on the task and model.

---

1️⃣3️⃣ What is Top-P in LLMs?

πŸ‘‰ Top-P, also called nucleus sampling, controls which candidate tokens are considered when generating text.

Instead of considering every possible next token, the model selects from a group of tokens whose combined probability reaches a specified threshold.

πŸ“Œ Lower Top-P β†’ More focused choices
πŸ“Œ Higher Top-P β†’ More diverse choices

πŸ’‘ Temperature and Top-P are both generation controls, but they influence sampling in different ways.

---

1️⃣4️⃣ What is Zero-Shot Learning in Generative AI?

πŸ‘‰ Zero-shot learning means asking an AI model to perform a task without providing an example of the desired task in the prompt.

Example:

Translate this sentence into French:
"Artificial Intelligence is powerful."


No translation example is provided.

πŸ’‘ The model relies on patterns and capabilities learned during training.

---

1️⃣5️⃣ What is Few-Shot Learning?

πŸ‘‰ Few-shot learning means providing the AI model with a small number of examples in the prompt before asking it to perform the task.

Example:

Positive: "I love this product." β†’ Positive

Negative: "This product is terrible." β†’ Negative

"I really like this service." β†’ ?


The model can infer the expected pattern from the examples.

πŸ“Œ Zero-Shot β†’ No examples
πŸ“Œ Few-Shot β†’ Few examples

πŸš€ Generative AI Interview Questions with Answers (Part 4)

1️⃣6️⃣ What are Parameters in an AI Model?

πŸ‘‰ Parameters are the internal values learned by an AI model during training. They help the model learn patterns and relationships from data.

For example, neural networks learn parameters such as:

πŸ”Ή Weights
πŸ”Ή Biases

πŸ“Œ Training Data β†’ Learning β†’ Parameters β†’ Trained Model

πŸ’‘ Generally, a larger number of parameters can allow a model to represent more complex patterns, but it also increases computational requirements.

---

1️⃣7️⃣ What is the Difference Between Fine-Tuning and RAG?

πŸ‘‰ Fine-Tuning changes a model's learned parameters by training it further on task-specific data.

πŸ‘‰ RAG keeps the model's parameters unchanged and provides relevant external information as context during generation.

πŸ“Œ Fine-Tuning β†’ Changes model behavior
πŸ“Œ RAG β†’ Provides external knowledge

Example:

Fine-Tuning: Teach a model a specific response style or task.

RAG: Let a chatbot answer questions using a company's latest documents.

---

1️⃣8️⃣ What is RLHF?

πŸ‘‰ RLHF stands for Reinforcement Learning from Human Feedback. It is a method used to align AI model behavior with human preferences.

Basic process:

text id="f2m8cz"
Pre-trained Model
↓
Human Feedback
↓
Preference Data
↓
Optimization
↓
Better-Aligned Model


πŸ’‘ Human feedback can help models produce responses that are more useful, relevant, and aligned with desired behavior.

---

1️⃣9️⃣ What is AI Safety?

πŸ‘‰ AI Safety focuses on designing and deploying AI systems in ways that reduce harmful, unreliable, or unintended behavior.

Important areas include:

πŸ”Ή Preventing harmful outputs
πŸ”Ή Protecting user data
πŸ”Ή Reducing bias
πŸ”Ή Improving reliability
πŸ”Ή Human oversight
πŸ”Ή Responsible deployment

πŸ’‘ AI safety becomes especially important when AI systems are used in high-impact applications.

---

2️⃣0️⃣ What are AI Guardrails?

πŸ‘‰ AI Guardrails are rules, filters, validation mechanisms, or controls designed to keep an AI system's inputs and outputs within defined boundaries.

Examples:

πŸ”Ή Content Filtering
πŸ”Ή Input Validation
πŸ”Ή Output Validation
πŸ”Ή PII Protection
πŸ”Ή Tool Access Controls
πŸ”Ή Policy Enforcement

πŸ“Œ User Input β†’ Guardrails β†’ AI Model β†’ Guardrails β†’ Output

πŸ’‘ Guardrails help make AI applications more controlled, reliable, and safer.

🧠 NLP Interview Questions with Answers (Part 1)

1️⃣ What is Natural Language Processing (NLP)?

πŸ‘‰ NLP is a branch of AI that enables computers to understand, process, analyze, and generate human language.

Applications:

πŸ”Ή Chatbots πŸ€–
πŸ”Ή Machine Translation 🌐
πŸ”Ή Sentiment Analysis 😊
πŸ”Ή Text Summarization πŸ“
πŸ”Ή Speech Recognition πŸŽ™οΈ

---

2️⃣ What is Tokenization in NLP?

πŸ‘‰ Tokenization is the process of breaking text into smaller units called tokens, such as words, subwords, or sentences.

Example:

text id="npl8x2"
"I love Machine Learning"
↓
["I", "love", "Machine", "Learning"]


πŸ’‘ Tokenization is usually one of the first steps in NLP processing.

---

3️⃣ What is Stop Word Removal?

πŸ‘‰ Stop words are common words that may carry relatively little useful information for certain NLP tasks.

Examples:

the, is, a, an, and, of, in


Example:

"The cat is on the table"
↓
"cat table"


πŸ’‘ Stop-word removal is task-dependent and is not always appropriate, especially for modern language models.

---

4️⃣ What is Stemming in NLP?

πŸ‘‰ Stemming reduces words to a simpler root-like form, usually by removing prefixes or suffixes.

Example:

playing
played
plays
↓
play


πŸ’‘ Stemming is fast, but the resulting root may not always be a valid dictionary word.

---

5️⃣ What is Lemmatization in NLP?

πŸ‘‰ Lemmatization converts a word into its base or dictionary form using linguistic information.

Example:

running β†’ run
better β†’ good
studies β†’ study


πŸ“Œ Stemming β†’ Rule-based word reduction
πŸ“Œ Lemmatization β†’ Linguistically informed base form

πŸ’‘ Lemmatization generally produces more meaningful results than stemming, but can require more processing.
