# Fornire esempi (few-shot prompting)
<a name="prompting-provide-examples"></a>

Includendo alcuni esempi della tua attività nel prompt, puoi creare un modello strutturato da seguire per Amazon Nova 2. In questo modo, è possibile ridurre l’ambiguità e migliorare la precisione e la qualità dell’output. La tecnica che consiste nel fornire esempi chiari per rendere le risposte del modello più vicine al risultato desiderato si chiama *few-shot prompting*.

Il few-shot prompting consiste nel fornire al modello linguistico alcuni esempi (shot) dell’attività, insieme al formato di input e output, e quindi chiedergli di generare l’output per un nuovo input basato sugli esempi forniti. Questo metodo aiuta anche a chiarire istruzioni o attività complesse, facilitando la comprensione e l'interpretazione di ciò che viene richiesto da Amazon Nova 2.

**Come può aiutare l’aggiunta di esempi al prompt:**

L’aggiunta di esempi può aiutare il modello a produrre: 
+ risposte coerenti e uniformi allo stile degli esempi; 
+ risposte efficienti grazie alla diminuzione della probabilità di interpretare erroneamente le istruzioni e alla riduzione al minimo delle allucinazioni.

La portata del miglioramento delle prestazioni del modello tramite il few-shot prompting dipenderà dalla qualità e dalla diversità degli esempi scelti. I seguenti elementi illustrano quali sono le caratteristiche di buoni shot nel prompt:
+ **Seleziona diversi esempi**: gli esempi scelti devono rappresentare la distribuzione prevista input/output in termini di diversità (dai casi d'uso comuni ai casi limite) per coprire adeguatamente i casi d'uso pertinenti. È importante evitare qualsiasi bias negli esempi, poiché un bias negli input può causare bias anche negli output.
+ **Livelli di complessità corrispondenti**: la complessità degli esempi forniti deve essere in linea con l’attività o lo scenario di destinazione. È importante assicurarsi che il grado di complessità sia mappato tra l’input previsto e l’esempio scelto nel prompt.
+ **Pertinenza garantita**: gli esempi selezionati devono essere direttamente pertinenti al problema o all’obiettivo in questione. Ciò garantisce la coerenza e l’uniformità delle risposte. 

**Suggerimento**  
Se i suggerimenti precedenti non funzionano, consigliamo di creare un sistema basato su generazione potenziata da recupero dati (RAG) che migliori il prompt con una selezione dinamica di shot basata sulle analogie tra la query di input dell’utente e un pool di shot disponibile.

## Esempio 1: fornire esempi nel prompt dell’utente
<a name="example-collapsible1"></a>

In questo caso, l’utente sta cercando di classificare i ticket di assistenza clienti in entrata in categorie predefinite. Puoi fornire ai modelli di Amazon Nova 2 alcuni esempi di ticket classificati correttamente per migliorare la comprensione delle categorie e della lingua utilizzata nei ticket. Gli esempi devono essere concisi e rappresentare tutte le attività previste dall’applicazione. Se esiste un nome di campo specifico significativo per le attività, come `Ticket` o `Category` in questo esempio, l’utente può utilizzare tali campi seguiti direttamente dai due punti `":"`.

Utente:

```
Please classify the following customer support tickets into one of the categories: "Technical Issue," "Billing Inquiry," or "General Inquiry." 

Ticket: "Can you explain why my latest bill is higher than usual? I haven't changed my plan."
```

Assistente:

```
The customer support ticket should be classified as a "Billing Inquiry."

 Here’s the reasoning:
 - The customer is asking about the reason for a change in their latest bill amount.
 - The context revolves around billing and payment, which falls under the category of "Billing Inquiry."

## Esempio 3: fornire esempi nel prompt di sistema
<a name="example-collapsible3"></a>

In questo caso, puoi specificare una sezione “Esempi” e poi elencare una serie di esempi all’interno del prompt di sistema. Questa modalità di fornire esempi nel prompt è particolarmente utile se gli esempi sono lunghi e complessi e aiuta il modello a individuare gli shot di esempio.
