This approach has numerous potential applications in domains like self-driving cars and brain-machine interfaces, where machine learning models must adapt to chang
What is IPL?
Iterative Pseudo-Labeling (IPL) is a semi-supervised algorithm used in speech recognition. The algorithm fine-tunes an existing model using both labeled and unlabeled data. IPL is known for efficiently performing multiple iterations of pseudo-labeling on unlabeled data as the acoustic model evolves.
How Does IPL Work?
IPL works by utilizing unlabeled data, which is not labeled with the correct transcriptions of speech, along with the labeled data, to fine-tune the existing model
