摘要: We introduce an unsupervised approach to efficiently discover the underlying features in a data set via crowdsourcing. Our queries ask crowd members articulate feature common two out of three displayed examples. In addition, we provide binary labels for these discovered on remaining The triples are chosen adaptively based previously set. This is motivated by formal framework elicitation that and analyze this paper. natural models features, hierarchical independent, show simple adaptive algorithm recovers all with less labor than any nonadaptive algorithm. savings as result automatically avoiding redundant or synonyms. Experimental results validate theoretical findings usefulness approach.
