We have also introduced a preliminary study for classification of depression severity based on our speech-rate features using phone length derived from phone-recognition boundaries.
In the pre-computed indicators model, indicators derived from mobile phone data are released to third-parties.
Its findings – derived from 1,012 phone interviews conducted in 2015 – suggest that companies with good corporate reputations can often attract the best talent, for less money, than their competitors.
Where the FISC had stopped short of permitting the NSA to acquire the increasingly precise location information that can be derived from cell phone logs, for instance, it remains unclear whether this new authority could be used to compel the production of people "linked" to a suspect by physical proximity rather than direct contact.
Our research implies that features derived from mobile phone data may be useful in measuring and predicting economic development, thereby complementing scarce economic statistics in developing countries.
The same is true for data on human mobility derived from mobile phone traces that provide detailed time-resolved information about the location of users [35].
Using a different approach, Bogomolov et al. use indicators derived from mobile phone traces to predict whether a certain area will be a crime hot spot in the next month [180].
The location given will usually be the size of an urban neighborhood, with information derived from a phone's global positioning system and data received from cellular towers or wi-fi antennas.
Using dynamically updated features such as the estimated number of people in each area, or the age, gender and work/home/visitor group splits derived from mobile phone data, their model achieves almost 70% accuracy in predicting whether a given area is at risk of being the scene of a crime in the next month.
A question naturally arises is how would the proposed template-matching methods interact with an underlying acoustic model from which the GMMs are derived and the phone or word lattices are generated, and of particular interest is that as a baseline HMM system improves, whether the performance gain we have observed by the proposed template matching methods can still hold.
Mobility estimates derived from mobile phone data were better able to predict the percentage of households in a sublocation missing immunizations or antenatal care than were estimates of travel times to health facilities.
