The entire AI ecosystem is at risk without trust.

Ongoing community data protection

Socially responsible use of community data needs to be mutually beneficial: the more potential partners are willing to contribute to community development, the more access to community content they receive.

Identifying hash algorithms

Given a hash value, an you determine what algorithm produced it? Or what algorithm probably produced it? Obviously if a hash value is 128 bits long, then a 128-bit algorithm produced it. Such a hash value might have been produced by MD5, but not by SHA-1, because the former produces

Testing random number generators

Random number generators are subtle. Unless the generator is some physical device, random number generators (RNGs) are usually technically pseudorandom number generators (PRNGs), deterministic algorithms designed to mimic randomness. Suppose you have a PRNG that produces the digits 0 through 9. How might you test the output to see whether

Limitations on Venn diagrams
