Compared to the predecessor experiment Belle, Belle II plans to increase the peak luminosity by a factor of <40, by employing nano-beam technology in the interaction region. In particular the new, innermost sub-detector of Belle II - the Pixel Vertex Detector (PXD) - is in close proximity to the interaction point. This allows for the detection of particles, which do not leave a signal in the outer sub-detectors. Among these, Highly Ionizing Particles (HIPs) encounter a characteristically high energy loss, limiting their penetration depth into the detector. Anti-deuterons, magnetic monopoles and stable tetraquarks as possible HIPs are considered. Without a signal in the outer sub-detectors, no track trigger is issued, resulting in possible non-observation. Therefore, in this talk, the possibility of identifying HIPs solely with information provided by the PXD is presented, by using neural network algorithms operating in a multidimensional parameter space of e.g. PXD cluster data.
