To solve the problem that MDS cannot effectively be used for incremental data index, the paper proposes a neural network based incremental data indexing approach. In this approach, first a small number of data is indexed with MD, and the index is used to train neural network. New data then can be indexed with the trained neural network. The time complexity of indexing data with trained neural network is O(n). Our experimental results show our method can effectively perform incremental data indexing, and can keep well the distance information between data objects.
