They still seem to have created a model that fit the outcomes. There's no cross-validation here (since there's only two data points).
The real question is whether they can take this fitted model and apply it to future movies.
- hazzen 17y agoGo figure: by counting how many people are excited for a film the week before it opens, you can estimate how much money it makes. Even if the model is perfect and works everytime, it is not giving you any useful information. If the prediction can be moved from one week out to a month or more out from the release of the film, there may be actual applications. For instance, helping theaters decide which movies to show and on how many screens, or how many weeks to run a movie for.
- toby 17y agoTotally agree with you -- I was just pointing out that the model in the article was never blind tested. It's not clear that it even works within its limited domain.
- robryan 17y agoProblem is though that I doubt there would be much chatter that far out for a method like this to be overly useful. Chatter is usually the result of advertising with movies so being able to use it to predict things like what kind of advertising spend to use would be hard. Even without practical information it is still a good demonstration of the type of information that can be extracted from twitter that would have been very hard previously online.
