Domain ontology - PowerPoint PPT Presentation

This study presents the effectiveness of gradual fine-tuning in low-resource domain adaptation, highlighting the benefits of gradually easing a model towards the target domain rather than abrupt shifts. Inspired by curriculum learning, the approach involves training the model on a mix of out-of-doma

Domain adaptation in machine learning involves transferring knowledge from one domain to another. It addresses the challenge of different data distributions in training and testing sets, leading to improved model performance. Techniques like domain adversarial training and transfer learning play a k

Injective functions map elements from the domain to the range uniquely, while surjective functions ensure every element in the co-domain has a corresponding element in the domain. The negation of injective means finding x1 and x2 in the domain with the same function value but not equal, whereas for

Recall the definition of a function, where each element in the domain is related to exactly one element in the co-domain. Arrow diagrams can visually represent functions from finite sets X to Y. In this example, a function is defined from X = {a, b, c} to Y = {1, 2, 3, 4} using arrow diagrams, showc
