WSJ: Netflix Prize A “Turning Point” For Open Innovation

With Netflix Inc. paying out a $1 million prize on Monday to a team of outside researchers that improved its movie recommendation algorithm, two venture-backed start-ups are overjoyed that the “open innovation” model is spreading.

BellKor’s Pragmatic Chaos takes the price for Netflix’s recommendation-improvement contest.

Open innovation “like any big change in business takes time to promulgate,” said David Ritter, the chief technology officer of InnoCentive Inc. “The Netflix prize is a bit of a turning point.”

InnoCentive provides a platform for companies to host challenges seeking outside solutions to problems. Prizes and challenges range from a $5,000 reward from a company seeking creative ways to get men to shave more often to a $1 million prize for finding a biomarker for Lou Gehrig’s disease.

Ebay eyes social shopping for acquisition

January 21, 2009 By: dmreinke Category: Fashion 2.0, social shopping, wisdom of crowd

What kind of startups is eBay interested in?

Director of Corporate Strategy, Erik Stuart

To quote Erik from his interview on Vator.tv:

Social shopping is an interesting areas that still has potential that hasn’t been realized yet.

The problem is that I don’t think anything that we’ve seen today is really a magic bullet in terms of being compelling from a user perspective.

However, it’s a space we will continue to keep our eye on because if it is a compelling product and starts to show user traction, hopefully if I’m doing my job I will be looking at it long before it’s on the front page.

Erik is spot on.  No one has broken the code in fashion…but it will happen.  Erik we have the answer.  It’s definitely not Friend-based recommendations.  It’s definitely not Black box algorithmic recommendations.  The answer is to create a consumer review platform that allows users to sort fashion based on the user’s explicitly identified fashion peers.   Keep an eye on us.

Attention Fashion Buyer and Merchants: You will never be Mickey Drexler

January 05, 2009 By: dmreinke Category: prediction markets, wisdom of crowd

When I started StyleHop last year, one of my friends in acadamia shared Duncan Watts seminal work that essentially debunked the concept that marketers can predict hits by looking to the “influentials” in their product categories.  Watts revisits this topic in Sunday’s Washington Post article: So You Can’t Pick the Hits.  Neither Can Anyone Else:

Why is predicting so difficult?  Well, for lots of reasons, but two fundamental ones stand out. First, individuals are much harder to predict than they seem, not because people are infinitely complex, but because how we are apt to behave depends on subtle details of the situation.

The most interesting part of Watt’s work was his collaboration with Matthew Salganik and Peter Dodds to explore how certain songs become hits.  Here is what he found:

When participants knew what others liked, the popular songs became more popular and the unpopular songs less popular than when people made their choices independently. More surprisingly, however, we found that which particular songs become the most popular also became more unpredictable — in some cases social influence caused luck and randomness to overtake intrinsic appeal as the main factors driving success.

In the fashion industry, there has always been a strong belief that some individuals have near divine powers to predict what will be hot.  What we find over time, however, is that this almost never plays out unless the predictor has become a truetastemaker or brand unto themselves.  In other words, some individuals like Mickey Drexler, Ralph Lauran and Anna Wintour become so broadly followed that they in fact do have enormous outsized influence.

.

If Watt’s theories are correct, though, the magic fairy dust that helped these three rise to tastemaker status had less to do with their predictive fashion abilities and probably a lot more to do with hard work combined with a lot of luck.  All those buyers and merchants trying to become the next Mickey Drexler may be wasting their time .  The ability of individual merchants to consistently guess in advance of the season what styles will sell in which quantities will never rise much above a mediocre distribution.  Okay, I’m saying it:  Merchants simply can’t see or intuit the subtle nuance that affects consumer decision making in advance nor can they see how the trends will evolve and be accepted as the social influence evolves.

.

This is what makes StyleHop’s model so compelling.  Leveraging thousands of real live targeted consumer’s feedback we can improve upon the individual’s merchant’s forecasting ability leveraging the wisdom of the crowd.  Think of it this way, if the ability to predict fashion is a loser’s game (historical markdowns and high variation in sales performance in fashion support this) then wouldn’t it be better to just ask a large number of the target consumer which items they would like?  By the way, consumer products companies like Procter & Gamble have been doing this market research for decades prior to new product launches.

.

Longer term, with traction in the consumer marketplace, StyleHop’s model will be reinforced through the social influence Watts discovered.  Think of StyleHop like the leaderboard in Watt’s music study – directly influencing consumer behavior by showing consumer’s which items other folks have already said are great styles.  Imagine hangtags, in-store signage (or better yet geo-location iphone updates) highlighting the top-ranked StyleHop styles while you shop.  This peer validation, in my view, is more relevant and targeted than any fashion editorial in the magazines today.  Women would love to know that other real women like a particular style before they buy it.

Would love comments if you have them.

In Defense of Prediction Markets

January 17, 2008 By: dmreinke Category: prediction markets, wisdom of crowd

While StyleHop isn’t modeled to be a true prediction market where currency is used to wager on and predict winners, the idea is the same. Across many fields, the wisdom of the crowd is trumping the prognosticators and so-called expert forecasters. Just recently, however, there has been quite a bit of criticism of prediction markets.

The criticism started because the prediction markets did not accurately forecast the democratic primary outcome in New Hamphire. But it helps to remember the pundits were wrong, too. The promise of prediction markets and the wisdom of the crowd is not perfect forecasting. Rather, the claim is that you will see systematically higher forecast accuracy polling lots of ordinary folks versus asking just one expert. See both the blog at Hubdub.com and the Silicon Alley Insider’s post countering the criticism.

Hubdub is a London-based startup that is described in Techcrunch as a fantasy league for news. Users compete with each other to predict which news is most important. Hmmmm…….sounds a lot like what we’re trying to do in fashion at StyleHop. Good luck Hubdub!
