As future works, the FAWCai of OPOD sub-features will be formulated as the open-plan office building assessment indexing.
Given a total of K frames, L of which are natural frames, a hybrid estimate of the static features can be formulated as the constrained optimization problem widehat{c}_{h}=argmax_{c}pleft Wc|widehat{Q},lambdaright), (6).
Then, principal contour of scale space is formulated as feature vector, extracting features such as edge [14].
The extracted features are formulated as feature vectors and further constructed as feature space of high dimensionality.
To achieve high accuracy in recognizing the signal especially in low-SNR environments, the proposed method in this paper jointly exploits the features of signal in time and frequency domain, which was formulated as a unified feature function.
The MaxRel features list and mRMR features list were formulated as follows: (7) MaxRel features list : F M = [ f 1 M, f 2 M, …, f N M ], mRMR features list : F m = [ f 1 m, f 2 m, …, f N m ], where N represents the total number of features.
The MaxRel and mRMR features lists were formulated as follows: (6) MaxRel features list : F M = [ f 1 M, f 2 M, …, f N M ], mRMR features list : F m = [ f 1 m, f 2 m, …, f N m ], where N denotes the total number of features.
The reference period is formulated as "in the last month".
We selected a subset of the most effective features from each group to reduce the redundancy in these groups and formulated the feature selection task as an optimization problem and solved it using the genetic algorithm (GA), which has the ability to search the global optimum.
