Istituto Tecnologico del Massachusetts ha cancellato<\/a><\/noindex> set di dati Tiny Images<\/a><\/noindex>, che include una collezione annotata di 80 milioni di piccole immagini con risoluzione 32×32. Il dataset \u00e8 stato sostenuto da un gruppo che sviluppa tecnologie di visione artificiale ed \u00e8 stato utilizzato dal 2008 da vari ricercatori per l'addestramento e la verifica del riconoscimento degli oggetti nei sistemi di apprendimento automatico. <\/p>\n

La motivazione per la rimozione \u00e8 stata scoperta<\/a><\/noindex> uso di termini razzisti e misogini nelle etichette che caratterizzano gli oggetti raffigurati nelle immagini, cos\u00ec come la presenza di rappresentazioni considerate offensive. Ad esempio, c'erano immagini di organi genitali con termini colloquiali, immagini di alcune donne caratterizzate come \u00abprostitute\u00bb, ed erano stati utilizzati termini inaccettabili nella societ\u00e0 moderna per i neri e gli asiatici.<\/p>\n

Tuttavia, nel documento a cui si riferisce il MIT, vengono citati anche problemi pi\u00f9 gravi con tali collezioni: le tecnologie di visione artificiale possono essere utilizzate per sviluppare sistemi di riconoscimento facciale per il tracciamento di membri di gruppi vietati; una rete neurale per la generazione di immagini pu\u00f2 ricostruire l'originale a partire da dati anonimizati.<\/p>\n

La causa della comparsa di termini inaccettabili \u00e8 stata l'uso di un processo automatizzato che utilizza connessioni semantiche da un database lessicale della lingua inglese WordNet<\/a><\/noindex>, creato negli anni '80 all'Universit\u00e0 di Princeton. Poich\u00e9 controllare manualmente la presenza di lessico offensivo in 80 milioni di piccole immagini non \u00e8 praticabile, \u00e8 stata presa la decisione di chiudere completamente l'accesso al database. Il MIT ha anche esortato altri ricercatori a interrompere l'uso di questa collezione e a rimuovere le sue copie. Problemi simili sono stati osservati anche nella pi\u00f9 grande banca dati di immagini annotate ImageNet<\/a><\/noindex>, che utilizza anche collegamenti da WordNet.
