Finding the Best feature - The Best functions
Once one or more states have been chosen and the list of Entities Remaining has been reduced, some features may be more useful for the next step than others. For example, some features may be scored the same for all entities remaining, in which case choosing a state of that feature would not contribute to the identification.
Lucid3 has a Best algorithm for determining which is the best feature to address at any stage during an identification session. In general, a feature that would, on average, cause the list of Entities Remaining to be halved is a good feature to address.
There are two Best functions, Find Best and Sort Best (you can choose which Best function to use from the Best Mode item of the Features menu):
Find Best will determine which is the best feature to address next, and jump to and open that feature in Features Available. Next Best and Previous Best buttons on the toolbar allow navigation through the features list, if the first feature nominated cannot be addressed.
Sort Best will reorder the Features Available list so that features are sorted from best to worst. After a Sort Best, scan the top of the list for features that you can answer most easily.
Note that Sort Best only works using List View, as a tree of features cannot be sorted. See the topic Trees and Lists for more information.
Find the best feature to address next by clicking the Best button on the toolbar, or choosing Find Best or Sort Best from the Features menu.
If the list of entities in Entities Remaining changes after choosing a feature as suggested by Best, it may be worth clicking the Best button again to recalculate the next best feature to address.
Best can be automated, so that it is recalculated after each feature is addressed. Choose the option Automate>AutoBest from the Features menu. If you need to choose several states from one feature when AutoBest is on, hold down the Control key when choosing the states – AutoBest will be paused until the Control key is released.
