The ‘best’ things are; - fuzzy pattern matching algorithms for traffic analysis, human and other image target recognition.
- targeting algorithms that identify ‘suspicious’ individuals in large volumes of metadata.
- fraud analysis
- antagonistic image and video generation, both for fooling other fraud analysis, but also for propaganda, screwing with other actors, etc.
- directed high speed content generation (text, pictures, video) to spam the ‘algorithm’ and allow near realtime identification of additional buttons to push for given target audiences.
- massive marketing/ad manipulation.
Those budget line items (and the suppliers) really want to stay off the radar however, as it makes their life harder.
