Partially missing or blurring attribute values make data become incomplete during collecting data.
First algorithm divided the data set into a complete data set and non complete data set, and then the complete data set was clustered using the affinity propagation clustering algorithm, incomplete data according to the design method of the similarity metric is divided into the corresponding cluster.
Introduction Clustering analysis is an important method in data mining field, when clustering incomplete data, due to the presence of missing data, the clustering result is obviously reduced.
The intuition of these strategies is discarding missing data, only clustering the complete data.

The grain size of the cold-rolled specimens decreased with increase of reduction rate, c.f., as the rolling reduction increased to 90%, grain size along the direction normal to the sheet decreased to about 8μm in thick.
At a reduction rate of 50%, the elastic deformation resulted in a further downward shift and an increase in diffraction peak width at the peak position than the reduction rate of 20%.
For the reduction rate of 90%, the peak width is further increased while the angle remains unchanged.
Obviously, the transition time decreases as the reduction rate and the annealing temperature increases.
Here, the JMAK model incorporates microhardness data, instead of relying on microstructure and use a unified equation.

Results show a reduction in system energy losses for the optimized values, without violating any power system requirements.
Two case studies will be conducted by utilizing the data from a typical 132kV main intake substation; and simulated using DIgSILENT® PowerFactory software [8].
Instead, the 24-hour energy loss (in kWh) of the feeder is to be minimized, which is calculated as below: Eloss= t = 024 - ∆tPloss(t) × ∆t (1) Ploss(t) is the active power loss of the network (in kW), returned by PowerFactory after the load flow for corresponding data at time t is executed.
∆t is the time period, taken as 0.05 hour (or 3 minutes), which is equal to the smallest available duration of data sampling.
The middle penetration appears to give the most loss reduction for this case, which is somewhat similar to the total base load of the feeder.

Many algorithms for fitting and noise-reduction of range data from single feature have been proposed.
Many researches have been taken on fitting and noise-reduction method of range data.
Fitting and Noise-reduction Algorithm for Single Standard Profile Feature Since what we got from metrological system is range data, fitting of single profile feature in the pattern is the premise.
Then new profile feature fitting process is done through the left range data, as well as the same noise reduction process.
We simulated the range data of 4 planes and 2 cylinders according to method of generating range data proposed in Geometrical product specifications (GPS) and verification (ISO 10360-6-2001), then we added different equally proposed random noise and transformed the range data to a specified location in space and used the range data as original data to test the validity and robustness of our algorithm.

According to the data in Fig.4, the relationship between the surface resistivity and Bi2O3 content can be described as followed equation (Eq. 4), and the linear correlation coefficient is 0.991, as shown in Fig. 5.
What’s more, the slope of experiment results is higher than data of Eq. 3, indicated that Bi2O3 has a more significant effect on reducing the surface resistivity of MCP glasses.
While an obvious diffraction peak appeared after reduction.
Fig. 7 XRD patterns of glass sample 2: (a) before reduction; (b) after reduction.
These can be confirmed by the spectral transmission curve after reduction.

The data space is a collection of data[2] which is associated with the main body and its relationship to the body, all of the data in the data space can be controlled.
Therefore according to uncertain data, lots of data model and data management system are proposed such as TRIO, MayBMS and MystiQ and so on.
