Abstract: The diagnosis of paraquat-poisoned patients is one of the important problems in the medical diagnosis field. Current methods identify the paraquat-poisoned patients mainly depending on paraquat content in the body. However, the lack of such methods is treating paraquat-poisoned patients as a healthy person when there is little paraquat content in the body. Here, a new diagnostic method for paraquat-poisoned patients is proposed, which fuses gas chromatography-mass spectrometry, binary particle swarm optimisation and extreme learning machine together. In the proposed method, the data is collected by gas chromatography-mass spectrometry, the binary particle swarm optimisation is adopted to select the excellent feature sets and the extreme learning machine is adopted to identify the paraquat-poisoned patients. In contrast to current methods, the proposed method still can accurately identify the paraquat-poisoned patients even if there is little paraquat content in the body. In our experiments, two measures, which are accuracy and sensitivity, are used to evaluate our method. The accuracy and sensitivity get to 93.90% and 94.54%, respectively. We also made comparisons with four algorithms and the experimental results show that our method has better performance than the other four methods.
