In just a couple of years since launch, tinder’s simple UX and social/geo matching ability have made it a quick leader in the mobile dating space.
If we drop one dummy, then the three distances will no longer be identical!For example, if we drop : Distance(#1, #2) = 1 1 = 2 Distance(#1, #3) = 1 Distance(#2, #3) = 1 The above problem doesn't happen with m=2. The distance between a pair of records will be 0 if the records are the same color, or 1 if they are different. If we use two dummies, we are doubling the weight of this variable but not adding any information.While most teen romantic relationships do not start online, technology is a major vehicle for flirting and expressing interest in a potential partner.Reliable intellectual property (IP) statistics are an important tool in understanding trends in policy, business, and technology worldwide.Understanding the role social and digital media play in these romantic relationships is critical, given how deeply enmeshed these technology tools are in lives of American youth and how rapidly these platforms and devices change.
This study reveals that the digital realm is one part of a broader universe in which teens meet, date and break up with romantic partners.By using WIPO’s statistical data, users agree not to republish or commercially re-sell any of the data.In addition, when employing WIPO’s statistical data in any written work, users must cite “WIPO Statistics Database” as the source of the data.Those who've taken a Statistics course covering linear (or logistic) regression, know the procedure to include a categorical predictor into a regression model requires the following steps: For example, if we have X=, in step 1 we create three dummies: D_red = 1 if the value is 'red' and 0 otherwise D_yellow = 1 if the value is 'yellow' and 0 otherwise D_green = 1 if the value is 'green' and 0 otherwise In the regression model we might have: Y = b0 b1 D_red b2 D_yellow error [Note: mathematically, it does not matter which dummy you drop out: the regression coefficients b1, b2 now compare against the left-out category].When you move to data mining algorithms such as k-NN or trees, the procedure is different: we include all m dummies as predictors when m2) will distort the distance measure, leading to incorrect distances.Here are a few of the more interesting tinder statistics I was able to dig up.
