Possible sources include:
🔹 Biased Training Data
🔹 Unbalanced Data
🔹 Sampling Problems
🔹 Historical Bias
🔹 Evaluation Choices
📌 Data → Model → Output
Bias can enter at different stages of this process.

🧠 AI Search Algorithms Interview Questions with Answers (Part 1)
1️⃣ What is a Search Algorithm in AI?
👉 A Search Algorithm is a method used by an AI system to explore possible states or actions to find a solution to a problem.
📌 Basic process:
Initial State → Possible Actions → Search → Goal State
Examples:
🔹 Route Finding 🗺
🔹 Game Playing 🎮
🔹 Puzzle Solving 🧩
🔹 Planning 🤖
2️⃣ What is Breadth-First Search (BFS)?
👉 BFS explores nodes level by level, starting from the initial node.
Example:

        A
       / \
      B   C
     / \
    D   E

BFS Order:

A → B → C → D → E

💡 BFS typically uses a Queue.
⏱️ Time Complexity: O(V + E)
💾 Space Complexity: O(V)
3️⃣ What is Depth-First Search (DFS)?
👉 DFS explores a path as deeply as possible before backtracking.
Example:

        A
       / \
      B   C
     / \
    D   E

One possible DFS Order:

A → B → D → E → C

💡 DFS can be implemented using recursion or a stack.
⏱️ Time Complexity: O(V + E)
💾 Space Complexity: O(V)
4️⃣ What is A (A-Star) Search Algorithm?*
👉 A* is a heuristic search algorithm that uses both the cost already traveled and an estimate of the remaining cost to choose which node to explore.
It uses:

f(n) = g(n) + h(n)

🔹 g(n) → Cost from the start to node n
🔹 h(n) → Estimated cost from n to the goal
🔹 f(n) → Estimated total cost
Applications:
🗺 Pathfinding
🎮 Game AI
🤖 Robot Navigation
5️⃣ What is a Heuristic Function in AI?
👉 A heuristic function estimates how close a current state is to the goal.
It is commonly represented as:

h(n)

Example:
In a map-navigation problem, the straight-line distance to the destination can be used as a heuristic for some pathfinding problems.
💡 A good heuristic can reduce the amount of search required, but its properties affect whether an algorithm can guarantee an optimal solution.

🧠 AI Search Algorithms Interview Questions with Answers (Part 2)
6️⃣ What is Greedy Best-First Search?
👉 Greedy Best-First Search selects the node that appears closest to the goal based on a heuristic function.
It uses:

f(n) = h(n)

🔹 h(n) → Estimated cost from the current node to the goal
💡 Unlike A*, it does not include the cost already traveled.
⏱️ Time Complexity: Depends on the search space
💾 Space Complexity: Can be large
7️⃣ What is Hill Climbing in AI?
👉 Hill Climbing is a local search algorithm that repeatedly moves to a neighboring state that improves the objective value.
📌 Basic process:

Current State
     ↓
Check Neighbors
     ↓
Choose Better State
     ↓
Repeat

Common problems:
🔹 Local Maximum
🔹 Plateau
🔹 Ridge
💡 Hill climbing does not always guarantee finding the global optimum.
8️⃣ What is the Minimax Algorithm?
👉 Minimax is a decision-making algorithm commonly used in two-player, turn-based games.
One player tries to maximize the score, while the opponent tries to minimize it.
Example:

             MAX
           /     \
        MIN       MIN
       /  \      /  \
      3    5    2    9

The algorithm evaluates possible game states and chooses a move based on the assumed optimal play of both sides.
🎮 Commonly associated with:
• Chess
• Tic-Tac-Toe
• Checkers
9️⃣ What is Alpha-Beta Pruning?
👉 Alpha-Beta Pruning is an optimization of Minimax that eliminates branches that cannot affect the final decision.
It uses two values:
🔹 Alpha (α) → Best value found so far for the maximizing player
🔹 Beta (β) → Best value found so far for the minimizing player
📌 When:

α ≥ β

the remaining branch can be pruned.
💡 It can reduce the number of game-tree nodes that need to be evaluated while producing the same Minimax result.
🔟 What is Game AI?
👉 Game AI refers to techniques used to create systems that allow non-player characters (NPCs) or game agents to make decisions and respond to game situations.
Common techniques include:
🔹 Minimax
🔹 Alpha-Beta Pruning
🔹 Pathfinding
🔹 Finite State Machines
🔹 Behavior Trees
🔹 A* Search
Example:
🎮 An enemy NPC can use pathfinding to navigate toward a player while avoiding obstacles.

Large Teacher Model
        ↓
Knowledge / Soft Targets
        ↓
Smaller Student Model

Benefits:
🔹 Smaller model size
🔹 Faster inference
🔹 Lower computational requirements
💡 It is often used to create more efficient models.

👉 A Foundation Model is a large, broadly trained AI model that can be adapted to perform many different tasks.
Examples of tasks:
🔹 Text Generation
🔹 Classification
🔹 Summarization
🔹 Question Answering
🔹 Code Generation
📌 Large-Scale Pretraining → Foundation Model → Adaptation → Applications
2️⃣4️⃣ What is Multimodal Generative AI?

💡 The exact architecture can differ between models.
3️⃣2️⃣ What is Self-Attention?
👉 Self-Attention allows a model to determine which tokens in an input are most relevant to each other while processing a sequence.
Example:

"The animal didn't cross the road because it was tired."

Attention helps the model consider relationships between words across the sentence.
📌 Self-Attention is a core component of Transformer architectures.
3️⃣3️⃣ What is the Difference Between Encoder and Decoder in Transformers?
👉 Encoder and Decoder are two major Transformer components.
🔹 Encoder → Primarily processes input and builds contextual representations.
🔹 Decoder → Generates output tokens, often using previously generated tokens as context.
Examples:

Encoder → Understanding / Representation
Decoder → Text Generation

💡 Some models use encoder-only architectures, some decoder-only, and some use both.
3️⃣4️⃣ What is Pretraining in LLMs?
👉 Pretraining is the initial large-scale training stage where an LLM learns general language patterns, relationships, and representations from a large dataset.
📌 Basic process:

Large Dataset

Tokenization
      ↓
Model Training
      ↓
Learned Parameters
      ↓
Pretrained Model

💡 Pretraining provides the foundation that can later be adapted for specific applications.
3️⃣5️⃣ What is Inference in an LLM?
👉 LLM inference is the process of using a trained model to generate an output for a given input.
Example:

User Prompt

Tokenization
    ↓
LLM

Next-Token Prediction
    ↓
Generated Response

💡 During inference, the model uses its learned parameters to generate output rather than learning new parameters.
