长时间久坐行为往往会引起脑血流供应不足,进而导致注意力下降及执行功能表现减弱,并影响人脑学习的信息加工过程。以往研究表明体育活动对执行功能表现具有积极作用。然而,关于在久坐期间进行短时有氧运动干预是否

  1. Dear Prof. Xu,
    I am writing to get more information about SVM classification.

    I have one matrix with the inputs of the training data (X) and matrix with the labels (e.g. Y, my labels are -1, 1). I would like to do cross validation with n-fold (for example n=10) test on my data and I am going to obtain accuracy, Sensitivity and Specificity parameters to determine the performance of classifier.
    I did my classification based on your tutorial (http://www.alivelearn.net/?s=libsvm).

    bestcv = 0;
    for log2c = -1:3,
    for log2g = -4:1,
    cmd = [‘-v 5 -c ‘, num2str(2^log2c), ‘ -g ‘, num2str(2^log2g)];
    cv = svmtrain(heart_scale_label, heart_scale_inst, cmd);
    if (cv >= bestcv),
    bestcv = cv; bestc = 2^log2c; bestg = 2^log2g;
    end
    fprintf(‘%g %g %g (best c=%g, g=%g, rate=%g)\n’, log2c, log2g, cv, bestc, bestg, bestcv);
    end
    end
    Based on this code I can obtain cross validation accuracy, but in addition to accuracy I would like to obtain “predicted_label” according to cross validation.
    Would you please guide me how can I obtain final predicted_label after cross validation.

    Many thanks for kindly considering my question.
    I look forward to hearing from you.
    Best,
    Iman
