Locality Sensitive Hashing (LSH) is proposed to construct indexes for high-dimensional approximate similarity search. Multi-Probe LSH (MPLSH) is a variation of LSH which can reduce the number of hash tables. Based on the idea of MPLSH, this paper proposes a novel probability model and a query-adaptive algorithm to generate the optimal multi-probe sequence for range queries. Our probability model takes...
Constructing effective and efficient indexes for explosive growing multimedia data is a very challenging problem. To solve the problem, Haghani et al. provide a distributed similarity search method in high dimensions using Locality Sensitive Hashing. However, their method needs to estimate a global parameter on the whole dataset beforehand. It is impractical for a large-scale dynamical dataset. This...
The conventional reaction after detecting an attacker in an information system is to expel the attacker immediately. However the attacker is likely to attempt to reenter the system, and if the attacker succeeds in reentering, it might take some time for the defender's intrusion detection system (IDS) to re-detect the attacker's presence. In this interaction, both the attacker and defender are learning...
