Zero-Shot Learning

AI Fundamentals

Definition

Zero-shot learning is the ability of an AI model to perform a task without ever having seen specific examples of that task. Only a text description of what to do is provided. Modern models like Claude and GPT-4 excel at zero-shot, making it possible to use AI for new business tasks simply by describing what is needed.

Few-Shot Learning

Few-shot learning is a technique in which you provide the AI model with a few examples of the desired task directly in the prompt. For instance, by showing 3 emails classified as 'urgent' or 'normal', the model learns the pattern and classifies subsequent emails. It is a quick and practical way to customize AI without the need for fine-tuning.

AI Fundamentals

Prompt

A prompt is the instruction or question provided to an AI model to obtain a response. The quality of the prompt largely determines the quality of the output. Writing effective prompts (prompt engineering) is a key skill for getting the most out of AI tools in business, from report generation to content creation.

Machine Learning

Transfer Learning

Transfer learning is the technique of reusing a model trained on one task to solve another related task. Instead of starting from scratch, you start from a model that has already learned general patterns and adapt it to your specific case. It is the reason SMEs can achieve excellent AI results even with limited proprietary data.

Artificial Intelligence

Artificial intelligence is the computer science discipline that develops systems capable of performing tasks that normally require human intelligence: understanding language, recognizing images, making decisions. For Italian SMEs, AI represents a concrete opportunity to automate repetitive processes and achieve measurable competitive advantages.

Machine Learning

Machine learning is a subfield of AI in which systems automatically learn from data without being explicitly programmed for every scenario. ML algorithms analyze patterns in historical data to make predictions on new data. In business practice, it is used to forecast demand, classify documents, and optimize production processes.

Deep Learning

Deep learning is an advanced machine learning technique that uses neural networks with many layers (hence 'deep') to learn complex data representations. It underpins modern speech recognition, machine translation, and text generation systems. It requires large amounts of data but produces extraordinarily accurate results.

Neural Network

An artificial neural network is a computational model inspired by the workings of the human brain, composed of nodes (neurons) organized in interconnected layers. Each connection has a weight that is adjusted during training. Neural networks underpin nearly all modern AI systems, from image recognition to text generation.

Language Model

A language model is an AI system trained on enormous amounts of text to understand and generate natural language. Large language models (LLMs) such as GPT and Claude can write texts, answer questions, translate, and reason about complex problems. For businesses, they represent versatile assistants for any text-based task.

GPT

GPT (Generative Pre-trained Transformer) is the architecture behind ChatGPT, developed by OpenAI. It is a language model pre-trained on vast text corpora that can be used to generate content, answer questions, and perform complex text tasks. GPT-4 and subsequent versions have demonstrated increasingly advanced reasoning capabilities.
