Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for classifying an input time series into a class from a set of classes. In one aspect, a method comprises: receiving an input time series; processing the input time series using a reconstruction model to generate a reconstruction model output that comprises a plurality of channels, wherein each channel of the plurality of channels defines a respective output time series, and wherein each channel of the plurality of channels corresponds to a respective class from the set of classes; determining a respective reconstruction error for each channel of the plurality of channels based on an error between: (i) the output time series defined by the channel, and (ii) the input time series; and classifying the input time series as being included in a class from the set of classes based on the reconstruction errors.
