Inductive transfer

Inductive transfer, or transfer learning, is a research problem in machine learning that focuses on storing knowledge gained while solving one problem and applying it to a different but related problem.[1] For example, the abilities acquired while learning to walk presumably apply when one learns to run, and knowledge gained while learning to recognize cars could apply when recognizing trucks. This area of research bears some relation to the long history of psychological literature on transfer of learning, although formal ties between the two fields are limited.

The earliest cited work on transfer in machine learning is attributed to Lorien Pratt who formulated the discriminability-based transfer (DBT) algorithm in 1993.[2] In 1997, the journal Machine Learning published a special issue devoted to Inductive Transfer[3] and by 1998, the field had advanced to include multi-task learning,[4] along with a more formal analysis of its theoretical foundations.[5] Learning to Learn,[6] edited by Sebastian Thrun and Pratt, is a comprehensive overview of the state of the art of inductive transfer at the time of its publication.

Inductive transfer has also been applied in cognitive science, with the journal Connection Science publishing a special issue on Reuse of Neural Networks through Transfer in 1996.[7]

Notably, scientists have developed algorithms for inductive transfer in Markov logic networks[8] and Bayesian networks.[9] Furthermore, researchers have applied techniques for transfer to problems in text classification,[10][11] spam filtering,[12] and urban combat simulation.[13] [14] [15]

There still exists much potential in this field while the "transfer" hasn't yet led to significant improvement in learning. Also, an intuitive understanding could be that "transfer means a learner can directly learn from other correlated learners". However, in this way, such a methodology in transfer learning, whose direction is illustrated by,[16][17] is not a hot spot in the area yet.
