A novel adaptive image feature reduction approach for object tracking using vectorized texture feature is proposed in this paper.
The dimension reduction has advantages of reducing the computational cost in classification stage. 3) An adaptive learning rate was proposed to handle drifts caused by long term occlusion.
The definition is given as follows: (1) where The is given by least square loss which measures how much the training data is different from an assumed distribution.
(Fig.1 shows how the dimension reduction affects the image quality) is the labeled sign denoting which class the belongs to.
The 15% reduction rate is almost the highest that we could restore the image without noticeable visual quality loss.

Reduction of
anatase started just below 900ºC whilst rutile underwent reduction below 800ºC.
Positions of the peaks were taken from the ICDD database, however, peaks for the mixed valance TinO2n-1 phases where n>3 were only present up to 2θ = 50.2º and the data for these has taken from the paper by Bowden et al [16].
The onset of reductive mass loss in rutile system occurs at ~770ºC, about 100ºC lower than for anatase system Beyond the initial mass loss due to desorption, it is difficult to compare the curves in Fig.1, therefore the data has been differentiated so that the stages become more clearly defined.
Further heating to 1380ºC resulted in completing the reduction.

Its calculation procedure is shown as below:
Step1: Confirm the reference sequenceas a record in standard fault sets and comparative sequence, process the data being dimensionless.
Step2: calculate difference sequence, whereas comparative sequence which is unknown pattern, as reference sequence, which is history diagnosis data sequence.
Select the record in reduced diagnosis knowledge database as reference sequence, the data observed which transform to reduced space as comparative sequence.
Part of the data that sampled repeatedly and modeled by AR time-series in normal and wear state is shown in Table1.
Use 10 of 20 data acquainted with known state construct the learning samples data sets, the other 10 data as test data, after the original data normalized, Use respectively the grey relational analysis(method 1)and rough set based weighted grey diagnosis method(method 2) to recognize their status.

In recent years, a variety of manifold-based learning dimensionality reduction techniques have been proposed, which attempt to project the original data into a lower dimensional feature space by preserving the local neighborhood structure.
But, when the data is distributed in a nonlinear way, LDA may fail to discover essential data structures.
LPP can preserve the intrinsic geometry of data and yield an explicit linear mapping suitable for training and testing samples.
In order construct the objective function using labeled and unlabeled data, we give total-scatter matrix and the local scatter matrix , respectively.
As a result, OSMFA is more effective and efficient in face recognition.Experiments on face data show that the proposed algorithm has more discriminative power in comparison with SDA, MFA and ODLPP.

The collected vibration signal can be used for data mining as well as obtaining fault rule based on the rough set theory.
Vibration data mining based on Rough Set theory 60 vibration signal of the rotor experimental platform sample data were analyzed, and the normalized energy as condition attributes, using fault types as decision attribute to form fault diagnosis data tables.
So we chose 80% of the data as training samples, 16 samples of each fault samples, and take the remaining 20% of the data as a test sample.
Data partition is obtained according to the above method(Table 3).
The table 4 shows that the reduction produces 37 diagnosis rules.

Data for CDM projects were found in the database of the United Nations Framework Convention on Climate Change (UNFCCC), and the projects used were obtained from the National Agency of Electric Energy and a geo-referenced information system of the power sector.
Installed capacity, capacity factor, and reservoir area were data of interest, found in thegeo-referenced information system of the ANEEL (SIGEL) [5].
These data were for 1401 enterprises located on the Brazilian interconnected power system.
The average emission factor (Ef) of the interconnected system was calculated according to the data available at the MCT [6] website.
These data take into account the methodologies ACM0002 and AMS ID from the UNFCCC.

The microphone data were collected using a two-channel B&K analyzer 2144.
Measurement of these parameters were performed using pressure transducers, temperature and humidity sensors and recorded and processed by the data acquisition station - SAD-2, equipped with the ADAM modules 4000+, an integrated PC with the application GeniDAQ, equipped with a Visual Basic language [43].
In each measured points the data were recording by 10s with resolution 0,1s.
All figures present the data from 100 Hz to 10 kHz (Fig. 5).
It could offer the data basis and bionic model for the application of owl silent flight in engineering.
