Micro blogging is fast becoming a dominant medium in social media and its impact is evident in our daily lives. A massive amount of information is produced on a daily basis. It is observed that detecting hot topics can be very helpful for people to get essential information quickly. But due to short and sparse features, high flood of meaningless tweets and other characteristics of micro blogs, traditional...
Intelligent Data Analysis (IDA) is one of the most important approaches in the field of data mining, which attracts great concerns from the researchers. Based on the basic principles of IDA and the features of datasets that IDA handles, the development of IDA is briefly summarized from three aspects, i.e., algorithm principle, the scale and type of the dataset. Moreover, the challenges facing the...
A new robust watermarking 3D mesh model algorithm is presented in this paper. We embed two different watermarks into a 3D mesh. One of the two watermarks is based on feature information and another is embedded by Nielson norm. The two watermarks do not disturb each other. Since the algorithm is blind, it does not need the original model during extraction. The algorithm is applied to many mesh models...
