Multilayer pLSA for multimodal image retrieval

  title={Multilayer pLSA for multimodal image retrieval},
  author={Rainer Lienhart and Stefan Romberg and Eva H{\"o}rster},
It is current state of knowledge that our neocortex consists of six layers [10]. We take this knowledge from neuroscience as an inspiration to extend the standard single-layer probabilistic Latent Semantic Analysis (pLSA) [13] to multiple layers. As multiple layers should naturally handle multiple modalities and a hierarchy of abstractions, we denote this new approach multilayer multimodal probabilistic Latent Semantic Analysis (mm-pLSA). We derive the training and inference rules for the… CONTINUE READING
