Combining instance weighting and fine tuning for training Naïve Bayesian classifiers with scant training data

الملخص EN

-This work addresses the problem of having to train a Naïve Bayesian classifier using limited data.

It first presents an improved instance-weighting algorithm that is accurate and robust to noise and then it shows how to combine it with a fine tuning algorithm to achieve even better classification accuracy.

Our empirical work using 49 benchmark data sets shows that the improved instance-weighting method outperforms the original algorithm on both noisy and noise-free data sets.

Another set of empirical results indicates that combining the instance-weighting algorithm with the fine tuning algorithm gives better classification accuracy than using either one of them alone.
