Require: parameter_list (a list of input parameters) |
|
Ensure: feature_vector (a feature vector representing the parameters) |
| 1: Initialize an empty list called feature_vector
|
| 2: for each parameter in parameter_list
do
|
| 3: Identify the type of parameter using regular expressions: |
| 4: if parameter matches an integer pattern then
|
| 5: Normalize the integer |
| 6: Append the normalized value to feature_vector
|
| 7: esle if parameter matches a floating-point pattern then
|
| 8: Normalize the floating-point number |
| 9: Append the normalized value to feature_vector
|
| 10: else if parameter matches an IP address pattern then
|
| 11: Decimal form of the IP address |
| 12: Boolean value indicating if it is a private IP |
| 13: General string encoding |
| 14: Append all encoded parts to feature_vector
|
| 15: else if parameter matches a file path pattern then
|
| 16: Root directory encoding |
| 17: First-level directory encoding |
| 18: Second-level directory encoding |
| 19: General string encoding |
| 20: Append all encoded parts to feature_vector
|
| 21: else if parameter matches a file name pattern then
|
| 22: File name encoding |
| 23: File extension encoding |
| 24: General string encoding |
| 25: Append all encoded parts to feature_vector
|
| 26: else if parameter matches a URL pattern then
|
| 27: Top-level domain encoding |
| 28: Second-level domain encoding |
| 29: Subdomain encoding |
| 30: General string encoding |
| 31: Append all encoded parts to feature_vector
|
| 32: else if parameter matches a registry pattern then
|
| 33: Registry root key encoding |
| 34: Second-level registry key encoding |
| 35: Third-level registry key encoding |
| 36: General string encoding |
| 37: Append all encoded parts to feature_vector
|
| 38: else
|
| 39: Append General string encoding to feature_vector
