Refining Domain Knowledge for Domain Knowledge Guided Machine Learning
|Termin||Fr 19. August 2022|
|Kurzfassung||Advances in computational power have led to increased in interest in machine learning techniques. Sophisticated approaches now solve various prediction problems in the domain of healthcare. Traditionally, machine learning techniques integrate domain knowledge implicitly, by statistically extracting dependencies from their input data. Novel approaches instead integrate domain knowledge from taxonomies as an external component.
However, these approaches assume the existence of high quality domain knowledge and do not acknowledge issues stemming from low quality domain knowledge. It is thus unclear what low quality domain knowledge in the context of Domain Knowledge Guided Machine Learning looks like and what its causes are. Further it is not clearly understood what the impact of low quality domain knowledge on the machine learning task is and what steps can be taken to improve the quality in this context.
In this Thesis we describe low quality domain knowledge and show examples of such knowledge in the context of a sequential prediction task. We further propose methods for identifying low quality domain knowledge in the context of Domain Knowledge Guided Machine Learning and suggest approaches for improving the quality of domain knowledge in this context.
