This month we have Erik Lumer, VP of Personalization at Gilt, presenting "The art of personalization in flash commerce".
In this talk, I will discuss some of the unique challenges for personalization posed by an online flash sale business and illustrate some of the techniques adopted at Gilt. The short availability window of the products offered makes it impractical to use traditional item-level collaborative filtering techniques. Instead, preferences can be modeled at the attribute set level. Moreover, specific attribute similarity metrics based on information theoretic measures are seen to perform better when leveraging implicit customer preference cues derived from behavioral data. Finally, I will discuss some methods that we have tested to foster novelty in the recommendations of personally relevant products.
