実験結果の信頼性 (査読者A第2点)

[masuhar]

I wonder if the experimental results truly show the improvement
of the prediction accuracy. Surely, the accuracy of the proposed
method is 1.5%-point or 3.1%-point better. Does this always claim?
Do the results depend on the values of several parameters that the
authors decided? The section of “Threats to Validity” must provide
enough information on factors that affect th experimental results.
