a Hala Point packages 1152 Loihi 2 processors. The system supports up to 1.15 billion neurons and 128 billion synapses. Note that such scale far exceeds the requirements of the conducted experiments, but we wish to highlight the potential scale achievable by existing neuromorphic hardware. b Three network architectures based on the sparse block code model are implemented on Loihi 2 and compared. The readout of the feature space formed by the network is compared to the target function. c Average performance of the different network architectures is shown versus the number of blocks used in the representation (L = 20). Dashed lines correspond to the representations computed on the CPU. Shaded areas show the median standard error.
