PT - JOURNAL ARTICLE AU - Yul HR Kang TI - Estimation of time-varying decision thresholds from the choice and reaction times without assumptions on the shape AID - 10.1101/090217 DP - 2017 Jan 01 TA - bioRxiv PG - 090217 4099 - http://biorxiv.org/content/early/2017/01/10/090217.short 4100 - http://biorxiv.org/content/early/2017/01/10/090217.full AB - 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.
