O QUE É
MACHINE LEARNING?
"A computer program is said to learn from experience E with respect to some class of tasks T and
performance measure P if its performance at tasks in T, as measured by P, improves with experience E."
TOM MITCHELL
WTF?
Programa de computador
Aprende com a experiência
Na execução de tarefas E tem performance medida
Experience Performance Tasks
… e sua performance na tarefa melhora quanto mais experiência tiver
MACHINE LEARNING
“Conjunto de algoritmos e técnicas que fornece aos programas de computador a habilidade de aprender sem ser explicitamente programado”
