MatrixH calculates the output of the hidden layer in aneural network.

1. Discussion and Experimental results (Zi?ba et al.,2014) presented Boosted SVM for discovering rules from data setof the post-operative survival expectancy in the lung cancer patientsand extracted 16 features forprediction the post-operative survival expectancy. We tries to provide a way for predicting the post-operative survivalexpectancy in the lung cancer patients with a thoracic surgery data set (Zi?ba et al.,2014), 470 sample and number of input variablesis 16 features that are defined below.f1. DGN: Diagnosis – specificcombination of ICDf2.

AGE:Age at surgery Output:Risk1Y: True value if died in 1 year survival period The number of patients whosurvive after surgery in comparison to patients who die is higher, in a oneyear period; from total samples,400 patients are positive (survival) and70  patients are negative (died).

It is important, selectingpatients for thoracic lung cancer surgery with a low risk of post-operative inshort-term 30-day period or long-term 1 or 5 year survival (Zi?ba et al., 2014). We consider 1 year survival period for prediction thepost-operative survival expectancy in the lung cancer patients in this paper.

 We implementour proposed system in Matlab version 7.12 ona laptop,1.7 GHZ CPU, and we used the roots mean square error (RMSE) in order to determinethe evaluation indicator to determine the best method.
