Sommario/riassunto

Connectionism is a "hands on" introduction to connectionist modeling through practical exercises in different types of connectionist architectures. explores three different types of connectionist architectures - distributed associative memory, perceptron, and multilayer perceptron provides a brief overview of each architecture, a detailed introduction on how to use a program to explore this network, and a series of practical exercises that are designed to highlight the advantages, and disadvantages, of each accompanied by a website at http://www.bcp.psych.ualbert

Sommario/riassunto

Nel titolo del libro è riassunto l’augurio che le macchine si vestano finalmente di capacità sociali, così da indicarci chiaramente le loro intenzioni e i loro stati interni. Finché questo non avverrà dovremo stare in guardia, vigilare, perché le esigenze delle macchine non abbiano mai il diritto di precedenza sui bisogni umani. Intelligente, brillante, drastico nelle diagnosi, il saggio Lo sguardo delle macchine è un appello persuasivo per l’umanizzazione della tecnologia moderna, in cui il “guru della tecnologia maneggevole” ci introduce alla “psicoterapia” del design.
