# **Intended Use of WikiArt-Style**

**1. Style Classification in Machine Learning Models**
- Used as **labels** for training and evaluating models that classify artworks based on their artistic styles.
- Ideal for deep learning applications involving **convolutional neural networks (CNNs)** or **transformer-based vision models**.

**2. Style Transfer Applications**
- Acts as a **style reference** for neural style transfer algorithms (e.g., applying "Baroque" or "Cubism" to photos).
- Can guide users to select a target style from a curated list.

**3. Dataset Annotation**
- Used to **annotate** images in large datasets of paintings with consistent style names.
- Ensures compatibility with datasets like WikiArt, Kaggle’s Painter by Numbers, or custom curation.

**4. Educational and Exploratory Interfaces**
- Powers interfaces or apps for **exploring art history**, with filterable and searchable styles.
- Great for building **art recommender systems** or **virtual museums**.

**5. Generative Art Prompting**
- Assists in **text-to-image prompting** for generative models (e.g., Stable Diffusion, DALL·E) to specify desired styles.
- Example: "Generate a portrait in the style of Neo-Expressionism."

**6. Metadata Categorization in Art Databases**
- Useful for tagging and organizing artworks by style in digital archives or NFT marketplaces.
