A multi particle toy system with analytic solutions to investigate composite bosons in a harmonic potential

We construct a three dimensional toy systems with two types of fermions forming a composite boson. They are hold in a harmonic potential. The basis functions are constructed from an internal and an external Gauss function. All integrals have analytical solutions. The high symmetry reduces the number of integrals to be calculated for the symmetrized wave functions. With the internal Gauss function the composite bosons can be tuned from fermionic unbound behavior to bosonic bound behavior.

Few-shot learning using pre-training and shots, enriched by pre-trained samples

We use the EMNIST dataset of handwritten digits to test a simple approach for few-shot learning. A fully connected neural network is pre-trained with a subset of the 10 digits and used for few-shot learning with untrained digits. Two basic ideas are introduced: during few-shot learning the learning of the first layer is disabled, and for every shot a previously unknown digit is used together with four previously trained digits for the gradient descend, until a predefined threshold condition is fulfilled. This way we reach about 90% accuracy after 10 shots.
