What is positive unlabeled learning?
Learning from positive and unlabeled data or PU learning is the setting where a learner only has access to positive examples and unlabeled data. The assumption is that the unlabeled data can contain both positive and negative examples.
Does machine learning always need Labelled data?
The shift towards ML and AI technologies relies heavily on properly labeled data for machine learning (ML), so algorithms can use it to identify issues and suggest solutions. In other words, for data to be used for training models, it has to be labeled first.
What are soft labels in machine learning?
By talking about overconfidence in Machine Learning, we are mainly talking about hard labels. Soft label: A soft label is a score which has some probability/likelihood attached to it. Eg: (0.1 0.2 0.8) Hard label: A hard label is generally a part of either one of the two classes. It is binary in nature (0 or 1)
Which type machine learning needs data Labelling?
Supervised learning, the most common type, is a type of machine learning algorithm that requires data and corresponding annotated labels to train.
