Transfer language space with similar domain adaptation: a case study with hepatocellular carcinoma.
Transfer language space with similar domain adaptation: a case study with hepatocellular carcinoma. Journal of biomedical semantics Tariq, A., Kallas, O., Balthazar, P., Lee, S. J., Desser, T., Rubin, D., Gichoya, J. W., Banerjee, I. 2022; 13 (1): 8Abstract
BACKGROUND: Transfer learning is a common practice in image classification with deep learning where the available data is often limited for training a complex model with millions of parameters. However, transferring language models requires special attention since cross-domain vocabularies (e.g. between two different modalities MR and US) do not always overlap as the pixel intensity range overlaps mostly for images.METHOD: We present a concept of similar domain adaptation where we transfer inter-institutional language models (context-dependent and context-independent) between two different modalities (ultrasound and MRI) to capture liver abnormalities.RESULTS: We use MR and US screening exam reports for hepatocellular carcinoma as the use-case and apply the transfer language space strategy to automatically label imaging exams with and without structured template with >0.9 average f1-score.CONCLUSION: We conclude that transfer learning along with fine-tuning the discriminative model is often more effective for performing shared targeted tasks than the training for a language space from scratch.
