WebAug 28, 2024 · Standardizing is a popular scaling technique that subtracts the mean from values and divides by the standard deviation, transforming the probability distribution for an input variable to a standard Gaussian (zero mean and unit variance). Standardization can become skewed or biased if the input variable contains outlier values. WebApr 11, 2024 · The response is generated using the ‘policy’ that the model has learned in step 2. The policy represents a strategy that the machine has learned to use to achieve its goal; in this case, maximizing its reward. Based on the reward model developed in step 2, a scaler reward value is then determined for the prompt and response pair. buckaroo john tack
