Stops the entire experiment when the metric has plateaued for more than the given amount of iterations specified in the patience parameter. Args: metric: The metric to be monitored. std: The minimal standard deviation after which the tuning process has to stop. top: The number of best models to consider. mode: The mode to select the top results. Can either be "min" or "max". patience: Number of epochs to wait for a change in the top models. Raises: ValueError: If the mode parameter is not "min" nor "max". ValueError: If the top parameter is not an integer greater than 1. ValueError: If the standard deviation parameter is not a strictly positive float. ValueError: If the patience parameter is not a strictly positive integer. çü©ñÒMbP?é ÚminrÚmetricÚstdÚtopÚmodeÚpatiencecCsŒ|dvrtdƒ‚t|tƒr|dkrtdƒ‚t|tƒr|dkr"tdƒ‚t|tƒr+|dkr/tdƒ‚||_||_||_d|_||_||_ g|_ dS)N)rÚmaxz1The mode parameter can only be either min or max.ézDTop results to consider must be a positive integer greater than one.rz-Patience must be a strictly positive integer.z@The standard deviation must be a strictly positive float number.)
