- Common aliases: PNN and redes neuronales probabilisticas.
- Wikipedia title: "Probabilistic neural network".
- Wikipedia available languages (sitelinks): German (de), English (en), Spanish (es), Polish (pl), Ukrainian (uk).
- Wikidata sitelink_count for this entity: 5.
- Freebase ID: /m/0j66t2m.
- Microsoft Academic ID (discontinued): 134342201.
- The parent class feedforward neural network has a sitelink_count of 18.

## FAQs
### Q: What is a probabilistic neural network (PNN)?
A: A probabilistic neural network is a type of artificial neural network. It is categorized as a subclass of feedforward neural networks.

### Q: How is a PNN related to feedforward neural networks?
A: A PNN is a subclass of feedforward neural networks. Feedforward neural networks are defined as artificial neural networks whose connections between nodes do not form cycles.

### Q: What other names does a probabilistic neural network go by?
A: It is commonly abbreviated as PNN and known in Spanish as "redes neuronales probabilisticas."

### Q: Where can I find more publicly available information about PNN?
A: The entity has a Wikipedia article titled "Probabilistic neural network" available in at least five languages: de, en, es, pl, and uk. It also has identifiers on Freebase (/m/0j66t2m) and a discontinued Microsoft Academic ID (134342201).

## Why It Matters
Probabilistic neural network is a recognized, named architecture within the taxonomy of artificial neural networks. Its classification as a subclass of feedforward neural networks places it in a well-understood family of architectures characterized by acyclic node connections. The existence of a dedicated Wikipedia article in multiple languages and structured identifiers (Freebase, Microsoft Academic) indicates that the concept has been documented and referenced across information resources and research indexing systems. For those mapping the landscape of neural network types or aggregating references across databases, PNN is a distinct entry with standardized aliases and identifiers that facilitate cross-referencing. Its placement under the feedforward class clarifies the basic structural constraint (no cycles) that governs its topological category.

## Notable For
- Being a defined subclass of feedforward neural networks (acyclic connections).
- Having widely used aliases, including the abbreviation PNN and the Spanish name "redes neuronales probabilisticas."
- Documented presence on Wikipedia in at least five languages (de, en, es, pl, uk).
- Assigned persistent identifiers in data catalogs: Freebase ID /m/0j66t2m and Microsoft Academic ID 134342201 (discontinued).
