When does supervised domain adaptation outperform finetuning? 


Best insight from top research papers

Supervised domain adaptation outperforms finetuning when there is an acoustic mismatch between the pretraining and target datasets, and when there is a need to bring the clean dataset closer to the target domain through calibrated data augmentations . Additionally, combining fine-tuned features with feature transformation based methods can lead to improved domain adaptation performance . In the case of semi-supervised domain adaptation, where there are labeled source domain data and a small number of labeled target domain data, adapting the target domain data distribution through model transfer is a better solution than domain alignment by mixing annotated data from two domains .

Is finetuning from a pretrained model always better than training from scratch?5 answersFinetuning from a pretrained model is generally more beneficial than training from scratch across various machine learning domains. Studies show that pretrained models induce transferable invariances, contributing to improved downstream performance. In the realm of natural language processing, finetuning multilingual pretrained language models (MPLMs) through prompt-based methods enhances cross-lingual transfer capabilities significantly. Moreover, sparse fine-tuning approaches, which selectively update parameters, have been proven effective and stable, outperforming fully fine-tuned models in NLP tasks. However, fine-tuned models often suffer from overconfident predictions due to catastrophic forgetting, highlighting the importance of calibration methods that preserve pre-trained features. Additionally, novel paradigms like Prompt Regularization (ProReg) offer promising alternatives to traditional fine-tuning, showcasing consistent strong performance on various benchmarks.
When will finetuning from a pretrained model worse than training from scratch in image classification?5 answersFine-tuning from a pretrained model can be worse than training from scratch in image classification when the number of training iterations is increased, as indicated by. This phenomenon is observed to have a weak dependency on the pre-trained model, especially with large training iterations. In scenarios where the final prediction precision may not significantly benefit from the pre-trained model, training from scratch can yield comparable or even better performance. Additionally, when the pretrained features are good and there is a significant distribution shift, fine-tuning may lead to lower accuracy out-of-distribution compared to linear probing, showcasing a tradeoff between in-distribution and out-of-distribution accuracy.
What are some of the benefits of fine-tuning?5 answersFine-tuning has several benefits. It allows for the transfer of learned knowledge from pre-trained models to downstream tasks, improving accuracy in-distribution (ID). Fine-tuning can be particularly effective in tasks such as breast cancer detection using MRI images, where labeled data is limited. It also helps in preserving pre-trained knowledge while learning new knowledge from target data, mitigating negative transfer and improving generalization ability. In the context of Alzheimer's disease diagnosis, fine-tuning techniques combined with transfer learning have shown promising outcomes, aiding in early detection and improving patient care. Additionally, fine-tuning can address the challenge of insufficient training data and reduce the need for expensive labeling, making it a valuable approach in image classification tasks.
How to Fine-Tune BERT for Text Classification?5 answersTo fine-tune BERT for text classification, several approaches have been explored. One approach is to conduct exhaustive experiments to investigate different fine-tuning methods of BERT on text classification tasks and provide a general solution. Another approach is to implement various Bert-based fine-tuning models, such as adding a simple dense layer to the pre-trained Bert model, and extensively investigate their performance. Additionally, a BERT-based uncased model has been developed and fine-tuned to address the challenge of unbalanced text classification by varying the learning rate and maximum token length. Furthermore, a BERT-based text classification model called BERT4TC has been proposed, which constructs auxiliary sentences to address the limited training data problem and task-awareness problem. These approaches provide insights into how BERT can be effectively fine-tuned for text classification tasks.
How to fine tune NLP translator for industrial applications?5 answersFine-tuning NLP translators for industrial applications involves several steps. First, adapter modules can be used to specialize speech translation (ST) to specific language pairs with minimal additional parameters. Additionally, pre-processing and post-processing strategies can enhance the performance of NMT models without changing the model itself. Furthermore, explicitly learning bilingual syntactic constituent alignments can improve NMT by utilizing syntactic structures and scoring alignments. Finally, fine-tuning starts with a general-purpose base model and uses a small labeled training set to produce a model for a specific downstream application. By following these steps, NLP translators can be fine-tuned for industrial applications, improving their performance and suitability for specific language pairs and domains.
