Pseudocode Yes Alg. 1 summarizes the AGCBM algorithm, where Next, AGCBMRanking ,and Find Centroids respectively denote functions for accessing the next element of an ordered list, for ordering cases based on their competence calculated by Eq. 3, and for finding cases closest to the centroids of the case base. Value(c) is the solution value associated with case c, and Find Sol(c) is the CBR procedure used to generate the solution. Algorithm 2 Algorithm for value estimation (CAAR) Input: Q: input query n: number of source cases to adapt to solve query r: number of rules to be applied per source case CB: case base Output: Estimated solution value for Q
Open Source Code No The paper does not provide any explicit links or statements about the release of source code for the described methodology.
Open Datasets Yes We evaluated AGCBM1 s performance on four sample domains from the UCI repository (Frank and Asuncion 2010): Automobile (Auto), Auto MPG (MPG), Housing, and Computer Hardware (Hardware). For all data sets, records with unknown values were removed.
Dataset Splits Yes Ten fold cross validation is used for all experiments, and all methods parameters are tuned by using hill climbing on the training data.
Hardware Specification No The paper does not specify the hardware used for running experiments, such as CPU or GPU models, memory, or specific computing environments.
Software Dependencies No The paper does not provide specific software dependencies or their version numbers used in the experiments.
Experiment Setup Yes The parameters to tune for AGCBM1 are the number of source cases to use and the number of adaptations to apply per source case for estimating the case values, and α from Eq. 3. The size limit used in the CNN process was set based on the desired reduction in the training set size.
