This letter is a supplement to the previous paper “A Direct Approach for Determining the Switch Points in the Karnik-Mendel Algorithm”. In the previous paper, the enhanced iterative algorithm with stop condition (EIASC) was shown to be the most ineff... Read More

Type reduction operators for interval type–2 defuzzification (2018)
Journal Article
Runkler, T. A., Chen, C., & John, R. (2018). Type reduction operators for interval type–2 defuzzification. Information Sciences, 467, (464-476). doi:10.1016/j.ins.2018.08.023. ISSN 0020-0255

Fuzzy sets are an important approach to model uncertainty. Defuzzification maps fuzzy sets to non–fuzzy (crisp) values. Type–2 fuzzy sets model uncertainty in the degree of membership in a fuzzy set. Type–2 defuzzification maps type–2 fuzzy sets to n... Read More

Interval type-2 defuzzification using uncertainty weights (2017)
Journal Article
Runkler, T. A., Coupland, S., John, R., & Chen, C. (in press). Interval type-2 defuzzification using uncertainty weights. Studies in Computational Intelligence, 739, doi:10.1007/978-3-319-67789-7_4

One of the most popular interval type-2 defuzzification methods is the Karnik-Mendel (KM) algorithm. Nie and Tan (NT) have proposed an approximation of the KM method that converts the interval type-2 membership functions to a single type-1 membership... Read More

Empirical study of BIM implementation–based perceptions among Chinese practitioners (2017)
Journal Article
Jin, R., Hancock, C., Tang, L., Chen, C., Wanatowski, D., & Yang, L. (2017). Empirical study of BIM implementation–based perceptions among Chinese practitioners. Journal of Management in Engineering, 33(5), doi:10.1061/(ASCE)ME.1943-5479.0000538. ISSN 0742-597X

The global movement of building information modeling (BIM) is spreading the implementation of BIM from developed countries to other developing countries. Practitioners’ perceptions of BIM implementation in these developing countries, such as China, a... Read More

Activation induced changes in GABA: functional MRS at 7 T with MEGA-sLASER (2017)
Journal Article
Chen, C., Sigurdsson, H. P., Pépés, S. E., Auer, D. P., Morris, P. G., Morgan, P. S., …Jackson, S. R. (2017). Activation induced changes in GABA: functional MRS at 7 T with MEGA-sLASER. NeuroImage, 156, doi:10.1016/j.neuroimage.2017.05.044. ISSN 1053-8119

Functional magnetic resonance spectroscopy (fMRS) has been used to assess the dynamic metabolic responses of the brain to a physiological stimulus non-invasively. However, only limited information on the dynamic functional response of γ-aminobutyric... Read More

A direct approach for determining the switch points in the Karnik-Mendel algorithm (2017)
Journal Article
Chen, C., John, R., Twycross, J., & Garibaldi, J. M. (2018). A direct approach for determining the switch points in the Karnik-Mendel algorithm. IEEE Transactions on Fuzzy Systems, 26(2), doi:10.1109/TFUZZ.2017.2699168. ISSN 1063-6706

The Karnik-Mendel algorithm is used to compute the centroid of interval type-2 fuzzy sets, determining the switch points needed for the lower and upper bounds of the centroid, through an iterative process. It is commonly acknowledged that there is n... Read More

A new accuracy measure based on bounded relative error for time series forecasting (2017)
Journal Article
Chen, C., Twycross, J., & Garibaldi, J. M. (2017). A new accuracy measure based on bounded relative error for time series forecasting. PLoS ONE, 12(3), doi:10.1371/journal.pone.0174202. ISSN 1932-6203

Many accuracy measures have been proposed in the past for time series forecasting comparisons. However, many of these measures suffer from one or more issues such as poor resistance to outliers and scale dependence. In this paper, while summarising c... Read More

The role of anti-aquaporin 4 antibody in the conversion of acute brainstem syndrome to neuromyelitis optica (2016)
Journal Article
Cheng, C., Jiang, Y., Lu, X., Gu, F., Kang, Z., Dai, Y., …Hu, X. (in press). The role of anti-aquaporin 4 antibody in the conversion of acute brainstem syndrome to neuromyelitis optica. BMC Neurology, 16(1), doi:10.1186/s12883-016-0721-1. ISSN 1471-2377

Background: Acute brainstem syndrome (ABS) may herald multiple sclerosis (MS), neuromyelitis optica (NMO), or occur as an isolated syndrome. The aquaporin 4 (AQP4)-specific serum autoantibody, NMO-IgG, is a biomarker for NMO. However, the role of ant... Read More

Chen, C., John, R., Twycross, J., & Garibaldi, J. M. (2016). An extended ANFIS architecture and its learning properties for type-1 and interval type-2 models

In this paper, an extended ANFIS architecture is proposed. By incorporating an extra layer for the fuzzification process, the extended architecture is able to fit both type-1 and interval type-2 models. The learning properties of the proposed archite... Read More
