We use a high statistic data sample of $7.3 \times 10^{9}$ recorded
Au(1.23A GeV)+Au events to investigate $\Lambda^{0}$ baryon and $K^{0}_{S}$ meson
production below their free nucleon nucleon threshold. For the first
time these hadrons have been investigated using a neural network
to identify their weak decay topologys inside HADES. We highlight
details of the analysis procedure such as event selection, particle
identification and topological cuts on the decay kinematic before
presenting and discussing the transverse energy spectra as well as
production yields and their rapidity dependence. The results are
confronted with phenomenological models.
