  • To test if these dynamics could be used for information processing, the team created a simulation of the network and tried to teach it how to carry out a simple signal processing task-converting one waveform into another. (singularityhub.com)
  • Neural networks are also ideally suited to help people solve complex problems in real-life situations. (sas.com)
  • In some ways, they have achieved superhuman performance, such as computational speed, but they fail in one key aspect: When artificial neural networks learn sequentially, new information overwrites previous information, a phenomenon called catastrophic forgetting. (scienceblog.com)
  • They found that when the spiking networks were trained on a new task, but with occasional off-line periods that mimicked sleep, catastrophic forgetting was mitigated. (scienceblog.com)
