What is an embedding in machine learning?
An embedding is a way to turn words, images, or other data into numbers (vectors) so that a computer can understand and work with their meaning.

How do embeddings capture semantic meaning?
Embeddings place similar things close together in number space, so words or items with similar meanings have similar vectors.

Why are embeddings useful for tasks like search or recommendation?
Because embeddings group similar items together, computers can find related things quickly by looking for vectors that are close to each other.

What role does training data play in learning embeddings?
Training data helps the model learn which items are related by showing examples, so the embedding space organizes meaning based on real-world connections.

What does it mean when two embeddings have a small distance between them?
It means the two items are semantically similar or related, like synonyms or items used in similar contexts.

What does an embedding represent?
✗ Incorrect
Embeddings convert data into numbers that capture meaning, not random numbers or text.
Why are similar words close in embedding space?
✗ Incorrect
Embeddings group words by meaning, not by spelling or sentence position.
What helps embeddings learn semantic meaning?
✗ Incorrect
Training data with examples helps the model learn which items are related.
What does a small distance between two embeddings mean?
✗ Incorrect
Small distance means semantic similarity, not spelling or language.
Which task benefits from embeddings?
✗ Incorrect
Embeddings help computers find related items by comparing their vectors.
