Training Quantum Neural Networks: Barren Plateaus

How are you dealing with vanishing gradients in your QNNs? I've started using 'Local Cost Functions' and it seems to help with the barren plateau problem.

They care MUCH more about your research portfolio. If you have a published paper or a high-quality Playground project, you're ahead of the curve.

Just applied for the Google scholar program! Does anyone know how much weight they put on previous research experience vs. GPA?

Does the VQE ansatz account for the specific connectivity of the backend? If not, the SWAP gate overhead will likely drown out the signal.

I just tried running a small version of this on my laptop and it worked perfect! Why does the real hardware make it so much harder?

I've seen similar convergence issues in recent Qiskit versions. Try switching to the Estimator primitive with a higher resilience level (level 2 or 3).
