Over the last few decades, multiple-instance learning (MIL) has been successfully utilized to solve the content-based image/video retrieval (CBIR/CBVR) problem, in which a bag corresponds to a video scene and an instance corresponds to a frame caption. However, existing feature representation schemes are not effective enough to use MIL to detect video caption frames from news video, which hinders...
An open problem in hierarchical reinforcement learning is how to automatically generate hierarchies, e.g. options. We consider an immune clustering approach for automatic construction of options in a dynamic environment. The learning agent generates an undirected edge-weighted topological graph of the environment state transitions online. An immune clustering algorithm is then used to partition the...
