[3] Other analogies include other neurological systems such as that of Drosophila, and the vertebrate brain.
[4] According to some researchers, ablation studies have been deemed a convenient technique in investigating artificial intelligence and its durability to structural damages.
[5] Ablation studies damage or remove certain components in a controlled setting to investigate all possible outcomes of system failure; this characterizes how each action impacts overall system performance and capability.
The ablation process can be used to test systems that perform tasks such as speech recognition, object detection, and robot control.
With this in thought, Newell saw both as knowledge systems whereas procedures such as ablation can be performed on both to test certain hypotheses.
