AI FUNDAMENTALS

Temperature

AI Fundamentals

Definition

Temperature is a parameter that controls the randomness of responses generated by an AI model. Low values (0-0.3) produce predictable and conservative responses, ideal for structured tasks like document classification. High values (0.7-1.0) generate more creative and varied responses, useful for brainstorming and content generation.

Top-p (Nucleus Sampling)

Top-p is a sampling parameter that limits the model's choice to tokens whose cumulative probability does not exceed the value p. With top-p=0.9, the model considers only tokens covering 90% of the total probability, excluding improbable options. Together with temperature, it allows balancing creativity and reliability in AI responses.

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.

AI Fundamentals

Inference

Inference is the process by which an already-trained AI model produces predictions or responses from new data. While training happens once (and is expensive), inference happens every time you use the model. The operational costs of AI depend primarily on inference, which is why optimizing inference speed and cost is crucial for SMEs.

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.
