Palaeochannels are deposits of unconsolidated sediments or semi-consolidated sedimentary rocks deposited in ancient, currently inactive river and stream channel systems. It is distinct from the overbank deposits of currently active river channels, including ephemeral water courses which do not regularly flow. We have introduced a spectral characteristics-based palaeochannel information extraction...
In natural languages, compound words play an important role and their automatically extraction is very helpful in information retrieval, information extraction and text classification. We introduce a semi-supervised Chinese compound extraction approach based on HMM using bootstrapping in this paper. First, we define a set of tags BEMI {beginning, end, middle, independence}, which means the position...
The preprocessing of remote sensing imagery (RSI) has great importance on the results of the classification. In this paper, the algorithm of fast independent component analysis (ICA) and its application to the remote sensing imagery classification are presented, and different parameter has different effect on information extraction with ICA. The remote sensing imagery for experiment is from different...
