Pay Attention To History Or Repeat It

Biology - Mendel (1856)Father of genetics/heredity

Structure From Noise

Biology - Watson and Crick* (1953)Discovered Structure of DNA

* not without controversy

Structure From Noise

Genotype - whether or not you carry gene(s)

that manifest the characteristic

Phenotype - Physical/Observable traits ...Blue eyes

Structure From Noise

hypothetical analogue:

program structure = genotype

init - subroutine1 - sub2 - sub3A - T - G - C - … X - Y - Z

Structure From Noise

hypothetical analogue:

sandbox activity = phenotype

writefile - resolvedns - openconnectionA - T - G - ...

Locality Sensitive HashingPerceptual Hashing

Kinda Sorta The Same

Similarity Searching:

Traditional Hash: low collisions, hard to reverse, small ∆input = large ∆output

LH/pHash: small ∆input = small ∆output

Not All That Glitters

Going In The Other Direction:

Applying Information Theory to BiologyCould it apply to DLP?

Thanks
