The **averaged one-dependence estimators** or **AODE** algorithm works in the same way as a Naive Bayesian classifier, but it allows for mutual dependence between pairs of values within the input vector while continuing to ignore more complicated dependency relationships involving three or more values. The algorithm thus relaxes somewhat the ‘naivety’ of the Naive Bayesian classifier.

AODE performs well with a large number of (training or input) data items. However, because all pairs of input values are considered in a combinatorial fashion, it is not feasible to use the AODE algorithm with high-dimensional vectors (each data item has many input values). Where there are many input values, it can make sense to only use dependence estimators in those cases where interdependence is proven or at least suspected.

In the **weightily averaged one-dependence estimators** or **WAODE** algorithm, the contribution of each input vector variable to the model is weighted according to how well that variable classifies the data on its own. WAODE has been found to yield significantly better results than simple AODE.
