Machine learning and validation of account names, addresses, and/or identifiers

1. A computer-implemented method for determining if an account identifier is computer-generated, comprising:

receiving the account identifier;

dividing the account identifier into a plurality of fragments;

calculating a first feature of the plurality of fragments of the account identifier by calculating fragment frequencies of each of the plurality of fragments relative to a plurality of fragments associated with a plurality of account identifiers;

calculating a second feature of the account identifier by classifying alphanumeric character types of the account identifier;

calculating a third feature of the plurality of fragments of the account identifier by hashing the fragment frequencies to a commonness of each of the plurality of fragments of the account identifier; and

generating a plurality of data pairs, each data pair comprising a fragment of the plurality of fragments and an associated feature value, the associated feature value comprising the first feature, the second feature, or the third feature;

providing each of the plurality of data pairs to a probabilistic classifier model to determine if the account identifier is computer-generated.

2. The method of claim 1 , wherein, in response to determining that the at least one of the fragments of the account identifier cannot be found in the plurality of account identifiers, increasing a probability that the account identifier is computer-generated.

3. The method of claim 1 , wherein the probabilistic classifier model is trained with a training set of a plurality of account identifiers that are known to be or known to not be computer-generated, and wherein the training set allows the probabilistic classifier model to independently weigh the first feature, second feature, and third feature in order to more accurately determine if the account identifier is computer-generated.

4. The method of claim 1 , further comprising:

calculating one or more features of the account identifier by counting characters by character type.

5. The method of claim 1 , wherein at least one of the plurality of fragments is truncated to contain only consonants.

6. The method of claim 1 , wherein each character of at least one of the plurality of fragments is hashed according to character type.

7. The method of claim 6 , wherein each character type is selected from a group including consonant, vowel, number, and punctuation mark.

8. A system for determining if an account identifier is computer-generated, the system including:

a data storage device storing instructions determining if an account identifier is computer-generated; and

a processor configured to execute the instructions to perform a method including:

receiving the account identifier;

10. The system of claim 8 , wherein the probabilistic classifier model is trained with a training set of a plurality of account identifiers that are known to be or known to not be computer-generated, and wherein the training set allows the probabilistic classifier model to independently weigh the first feature, second feature, and third feature in order to more accurately determine if the account identifier is computer-generated.

11. The system of claim 8 , wherein the processor is further configured for:

calculating one or more features of the account identifier by counting characters by character type.

12. The system of claim 8 , wherein at least one of the plurality of fragments is truncated to contain only consonants.

13. The system of claim 8 , wherein each character of at least one of the plurality of fragments is hashed according to character type.

14. A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform a method for determining whether an account identifier is computer-generated, the method including:

receiving the account identifier;
