Até mesmo um gato pode fazer coisas que a IA não pode.
Fei-Fei Li
Python ganhou muito de sua proeminência recente com seu rico conjunto de ferramentas de IA. Neste capítulo, incluirei um pouco da história da IA, bem como alguns desenvolvimentos recentes. Dada a velocidade insana do desenvolvimento atual da IA, algumas referências serão inevitavelmente eclipsadas por objetos mais brilhantes e reluzentes.
A matemática tradicional permite que você ajuste a melhor linha ou curva a um grupo de pontos minimizando os erros. Porém, com os problemas de IA, estamos procurando padrões que podem ter uma forma multidimensional complexa, com muitos mínimos locais para erros. Isso é reconhecimento de padrões, e realmente não entendemos como o modelo faz isso. Na verdade, também não entendemos como fazemos isso.
Neste capítulo, abordaremos o seguinte:
-
A história recente da IA, incluindo insights que levaram a avanços
-
O papel do Python no desenvolvimento da IA, desde estruturas até modelos completos
-
Uma visão geral dos modelos de IA atuais mais proeminentes
-
Alguns exercícios de IA usando uma estrutura real baseada em Python
Primeiro, vamos dar uma olhada em algumas definições de termos que muitas vezes são misturados:
- Inteligência artificial (IA)
-
Um termo antigo e cada vez mais amplo para máquinas que imitam as habilidades humanas
- Aprendizado de ...
