^^Machine learning; apprendimento automatico.

machine learning ("apprendimento automatico" è l'espressione corretta in italiano)

• è una tecnica con cui il computer "impara", basandosi su una vastissima base di dati per formulare ipotesi e predizioni particolarmente accurate.
• rientra nel più ampio campo dell'intelligenza artificiale

Storia:

i primi progressi sono stati fatti per le immagini; lo sviluppo ha avuto uno sbalzo.

26-10-2019 lo sbalzo e' per il testo, con BERT Understanding searches better than ever before.

RL Reinforcement Learning

trial and error learning, apprendimento per tentativi ed errori.

Un agente impara

• interagendo con un ambiente
• per massimizzare una ricompensa che cresce piu' si avvicina al prefissato obiettivo

Boosting_(machine_learning) wp

1988 "Can a set of weak learners create a single strong learner?"

1990 Robert Schapire's affirmative answer to this question led to the development of practical boosting algorithms

1996 collaborating with Yoav Freund, he invented the AdaBoost algorithm (Adaptive Boosting), a breakthrough that led to their joint receipt of the Gödel Prize in 2003

data mining, machine learning, statistical analysis.

The language changes over time, but they refer to very similar things.

a quip:  “data mining = statistics + marketing”,

implying that if you can describe statistics in a way that grabs people’s attention, then what you are doing is data mining.

if an agent can learn to master an environment tabula rasa,
then you demonstrably have a system that is
discovering and learning new knowledge by itself.
