Preassembled Weakly Supervised Machine Learning

EPO granted patent EP4716911A1 to NEC Laboratories Europe GmbH for methods of training machine learning models using preassembled weakly supervised techniques. The invention addresses training scenarios where limited labeled data is available, using weakly supervised learning approaches to improve model performance without requiring large annotated datasets.

Technology companies and software developers working on machine learning systems should evaluate whether their training methods fall within the scope of the granted claims. Patent exclusivity extends for 20 years from the filing date, with designated states covering all major European markets including DE, FR, GB, IT, ES, NL, and others.
