News Event Understanding by Mining Latent Factors From Multimodal Tensors


We present a novel and efficient constrained tensor factorization algorithm that first represents a video archive, of multimedia news stories concerning a news event, as a sparse tensor of order 4. The dimensions correspond to extracted visual memes, verbal tags, time periods and cultures. The iterative algorithm then approximately but accurately ex- tracts… (More)
