In data-mining applications, it is common to transform (or map) nominal attributes into numeric ones in order to apply a specific model. However, a nominal attribute has typically no specific order in its values
Fig. 7shows a simple belief network for six variables: FamilyHistory, LungCancer, PositiveXRay, Smoker,Emphysema, and Dyspnea. All six variables are Boolean, meaning that they have a yes/no answer. The arcs inFig. 7represent casual knowledge about lung cancer, for example, people with Family...

Finally, the second and concluding radical move is the combination of the "buy" and "sell" states into one, but with a universal meaning — "market entry". Differently directed signals of an indicator are generally used symmetrically, in a similar manner. For example, overbought state according...

We conducted an ablation study to explore these interactions, meaning we applied the techniques simultaneously, but switched one off at a time as each technique was applied. The ablation study is shown in Table 6, alongside the accuracy results. The first row in Table 6 presents the NBEM ...
