Positive and negative correlation input attributes oriented subnets based double parallel extreme learning machine (PNIAOS-DPELM) and its application to monitoring chemical processes in steady state

Recent trends in neuromorphic engineering

“…The important challenge that still needs to be addressed is the feasibility in hardware implementation of these algorithms into algorithms, circuits, devices and systems, based on the nature of the primary contribution. The reader can view this figure in the supplementary material (Additional file 1) provided with the manuscript to click on the hyperlinks and navigate to the corresponding reference in the bibliography section [141][142][143][144][145][146][147] and approaches, that is eventually critical for realizing practical applications, such as on embedded platforms. The storage and computational capacity available on such platforms is limited, hence the algorithms need to have a low computational complexity, that translates to low-power requirements in hardware.…”

Data driven soft sensor development for complex chemical processes using extreme learning machine

“…The Pearson correlation coefficient is a tool to calculate the correlation coefficient between two variables (He et al, 2015b).…”

“…In previous researches, the Tennessee Eastman (TE) process has been widely adopted to test algorithm and evaluate performance (Downs and Vogel, 1993;He et al, 2015b). The flowchart of TE process is shown in Fig.…”

“…4. In PTA production plant (Xu and Zhu, 2008;He et al, 2015b), there are main three parts: the solvent dehydration tower, the reboiler and the reflux tank. Among the indicators of PTA plant assessment, the consumption of the acetic acid is an important indicator.…”

“…However, the influences of the input attributes on the output attributes were not taken into account. The different influences of the input attributes on the output attributes were taken into consideration using the Pearson correlation coefficient (He et al, 2015b). However, the learning speed of this model is limited and the model is not easy to build.…”
