decimal_scaling_normalization() Decimal scaling normalizes the values by dividing them by a suitable power of 10, based on the maximum absolute value in the dataset, often between -1 and 1. log_normalization() This method applies the natural logarithm function to the data, which can help redu...
For example if M = 17 the string "pub" would hash to 8. Since, chr(p) = 15, chr(u) = 20, chr(b) = 1, we have the concatenated binary string, 001111 010100 000001 This binary number represents the decimal number 62721. Taking 62721 mod 17 yields 8. We say ...
