TY - JOUR T1 - Estimation of time-varying decision thresholds from the choice and reaction times without assumptions on the shape JF - bioRxiv DO - 10.1101/090217 SP - 090217 AU - Yul HR Kang Y1 - 2017/01/01 UR - http://biorxiv.org/content/early/2017/01/10/090217.abstract N2 - When a decision is made based on a series of samples of evidence, the threshold for decision may change over time. Here we propose a one-shot algorithm that gives the entire threshold from the choice and decision times. Combined with a standard gradient descent procedure, the algorithm can efficiently identify the correct shape of the threshold without any hyperparameter for the threshold. ER -
