Learning of multimodal multiple chunks. (A) Left: Three chunks of apple (red), grape (blue), and banana (green) separated by random sequences recur at equal frequencies in the input. Right: These chunks are repeated without random sequence intervals. (B) The activity of the output units upon presenting each chunk while using input signals separated by random sequence intervals. The red, green, and blue shades indicate periods of learned input “apple,” input “banana,” and input “grape,” respectively. (C) The behavior of the output units upon presenting each chunk with input signals not separated by intervals. The red, green, and blue shades indicate periods of learned input “apple,” input “banana,” and input “grape,” respectively.
