The traditional gray model GM (1,1) is a kind of deviation of the exponential model, with fewer required data, forecasting of high precision and no need prior information, etc., but sometimes its forecasting is ineffective. “Poor” information systems are found everywhere. In this paper, a control approach to “poor” information systems, such as social economic systems, is proposed. Firstly, “poor” information processing and SCGM-model will be discussed. Secondly, we will develop an optimal controller of “poor” information systems. The result shows that the improved gray forecasting model SCGM-model, which is simple and practical and has higher accuracy and less error, can provide scientific theoretical basis for the relevant departments to make strategy. A demonstrating example shows the fitting and forecasting results of SCGM (1,h) are rather satisfactory

Many batch processes can be considered as a class of control affine nonlinear systems. In this paper, a novel adaptive learning approach for batch process modeling is developed. By introducing dynamic error transfer factor associated with mean squared error and using extended recursive least squares approach, the proposed approach can offer an effective fuzzy T-S predication model, resolve the conflicting problem of convergence speed and osciallation existed in recursive least squares method. The proposed modeling scheme is illustrated on a semi-batch reactor, and simulation results show its effectiveness and accuracy.

The research of knowledge granularity has been a hotspot at home and abroad. In incomplete information systems of the rough set, we give a formula, which calculates the attribute frequency directly without acquiring the discernibility matrix. Then applying it to the field of knowledge granularity, we give a quick calculation of the attribute reduction algorithm, which of the time complexity is O(|C|2 |U |) in the worst case. The example result shows that the algorithm is correct and efficient.

The source of APD photodiode sensor working noise and changes of photoelectric conversion SNR (Signal-to-noise ratio) are analyzed and computed in detail. The paper emphatically introduces the associated feature of APD sensor avalanche gain and photoelectric conversion SNR. Then the determination method of optimum avalanche multiplication rate on various noise factors is discussed. It can be seen from the research report that the optimum avalanche multiplication rate tends to reduce while the photocurrent Ip increases. Photoelectric conversion SNR decreases as APD operation bandwidth increases while the optimum avalanche multiplication rate remains unchanged. It has great theoretical significance and use value for determining and controlling APD sensor's characteristic of photoelectric transforming and so as to the design of low-noise interface circuit.

The extraction of complicated features is essential to the performance of online review sentiment analysis. Aside from conventional word bag features, the regular collocation features play more and more important role in that their structured expression shows great impact on the sentiment orientation. The presented paper propose to apply the mutual information method to mine the complicated features from online reviews, and extend features extraction from the conventional word bags to regular collocations. With extracted collocation features as inputs of Naive Bayes analysis model, experiments on online hotel reviews data show that the presented extraction method improves the performance of Naive Bayes model by 1.36%, and improves the performance of Maximum Entropy model by 0.92%. On the other hand the imbalance between positive and negative reviews leads to foul play where the majority features conceal the minority ones, and also the extreme sentiment of the minority introduces noise into the dataset. With respect to the imbalance problem and corresponding parameter estimation problem, one λ feature filtering strategy and Good Turing smooth method is adopted to improve further the performance of the sentiment analysis model.
