MIT researchers designed a computationally efficient algorithm for machine learning with symmetric data that also requires fewer data for training than conventional approaches. Their work could inform ...

Worked examples The graph below has a turning point (3, -2). Write down the nature of the turning point and the equation of the axis of symmetry.

All quadratic graphs have a line of symmetry. Positive quadratic graphs (where \ (a > 0\)) are U-shaped and have a turning point at the bottom of the curve.

Nature Physics - Going randomNow, Josh Izaac et al. show that this needn't be the case: by taking advantage of parity–time (PT)-symmetry, which emerges in non-Hermitian systems with gain and ...
