Nonlinear encoding in diffractive optical processors based on linear materials

The study compares simpler-to-implement nonlinear encoding strategies with the performance of data repetition-based methods, revealing that data repetition enhances inference accuracy but compromises universal linear transformation capability. Phase encoding without data repetition offers a simpler alternative with comparable inference...

Are AI-chatbots suitable for hospitals?

A study found that large language models, despite accuracy in medical exams, fail to consistently request necessary examinations and often deviate from treatment guidelines. In comparison to human doctors, AI diagnoses achieved lower accuracy rates, highlighting concerns about their suitability for everyday clinical practice.
