The description of big data, data processing technologies (big data), Hadoop storage systems are considered

Recent interest in semistructured data has led to a proliferation of XML-based standards which encompass applications ranging from multimedia applications and sensor data processing applications to financial applications and myriads of other more traditional applications. When semistructured paradigms are used to store sensor data and multimedia (e.g. image) data, we need to be able to handle u...

A novel online dynamic value system for machine learning is proposed in this paper. The proposed system has a dual network structure: data processing network (DPN) and information evaluation network (IEN). The DPN is responsible for numerical data processing, including input space transformation and online dynamic data fitting. The IEN evaluates results provided by DPN. A dynamic three-curve fi...
