Here’s a structured worksheet focused on distributed representations of words and phrases, along with an exploration of their compositionality. This format includes definitions, examples, and spaces for practice.
Distributed Representations of Words and Phrases Worksheet
Part 1: Definitions
| Term | Definition |
|---|---|
| Distributed Representation | A type of representation in which words or phrases are represented by vectors in a high-dimensional space. |
| Compositionality | The principle that the meaning of a phrase can be derived from the meanings of its individual parts. |
| Embedding | A mapping of discrete objects (like words) to continuous vector spaces. |
| Contextualized Embedding | Word representations that change depending on the surrounding context in which they appear. |
Part 2: Examples of Distributed Representations
| Word/Phrase | Distributed Representation (Vector) | Notes on Compositionality |
|---|---|---|
| Cat | [0.2, 0.1, 0.4, 0.3] | Represents the concept of a cat; similar to ‘dog’ in vector space. |
| Dog | [0.1, 0.3, 0.5, 0.4] | Related to ‘cat’ but has distinct characteristics. |
| Black cat | [0.25, 0.15, 0.45, 0.35] | Combination of ‘black’ and ‘cat’; compositional meaning derived from components. |
| Running fast | [0.5, 0.2, 0.6, 0.4] | Indicates an action; meaning derived from ‘running’ and ‘fast’. |
| The quick brown fox | [0.3, 0.4, 0.2, 0.5] | Represents a phrase; meaning built from individual words. |
Part 3: Practice
A. Analyze the Compositionality of the Following Phrases:
- Green apple
- Individual Word Representations:
- Green: [0.1, 0.3, 0.2, 0.5]
- Apple: [0.4, 0.2, 0.1, 0.6]
- Combined Representation: _____________________
- Notes on Compositionality: ______________________
- High jump
- Individual Word Representations:
- High: [0.5, 0.4, 0.1, 0.2]
- Jump: [0.3, 0.2, 0.4, 0.5]
- Combined Representation: _____________________
- Notes on Compositionality: ______________________
