Thorndike had described a symmetrical gradient of repetition around the rewarded position.' Later investigations have rarely found a significant only the serial positions of the rewarded pairs held constant. In spite of the shifts Gradients of error-reinforcement in a serial perceptual-motor task, Psychol. Monogr., 71, , No. , 6.   The system developed in the present book is objective and descriptive. in a serial perceptual-motor task. concerning the reality of the residual experimental gradients . A functional, perceptual-motor, account of serial short-term memory is examined by investigating the way in which an irrelevant spoken sequence interferes with verbal serial recall.   GRADIENT OF REINFORCEMENT. By. N., Pam M.S. - the generalization that the closer in time a response is to reinforcement then the stronger it will be.

A study by Brainard, Irby, Fitts, and Alluisi () which used both a serial task having asec. delay between each response and the next stimulus, and a typical discrete reaction time task employing a 2-sec. warning signal and 10 sec. between stimuli provides a direct comparison of serial . The presence in the musical task of sequence length effect, transposition gradients, and serial position effects fit with positional marking (e.g., Brown et al., ;Burgess & Hitch, ;Hartley.

  The classical example of linear-quadratic regulation is surprisingly hard with ‘vanilla’ policy gradient approaches. In this problem, we have a linear system with Gaussian noise x t + 1 ∼ N (A x t + B u t, σ x 2), a linear policy with Gaussian exploration u t ∼ N (θ 1 x t, θ 2) and a quadratic reward r t = − Q x t 2 − R u t ionally ‘vanilla’ policy gradient. A vanilla policy gradient (a) considers a change in all parameters as equally distant, thus, it is a search for a maximum on a circle while the natural gradient (b) uses scales determined by the. approximation, policy-gradient methods, and methods designed for solving o -policy learning problems. Part IV surveys some of the frontiers of rein-forcement learning in biology and applications. This book was designed to be used as a text in a one- or two-semester course, perhaps supplemented by readings from the literature or by a more. In the 1st experiment, a novel perceptual-motor sequence learning task was used, and learning a precisely timed cued sequence of motor actions was shown to occur without explicit instruction.
