Think back to grade school. Do you remember those standardized tests where you were given lists of meaningless words to memorize? Then, after taking a challenging math or reading section, you had to write down as many words from that list as you could remember? If you were terrible at this, don't fret. Just as you can train yourself to ace the SATs, there's a trick to becoming a master memorizer of random words.
Nowadays everyone is talking about data & analytics. Executives are figuring out how to turn it into value, researchers are writing huge numbers of papers about it and students are enrolling in massive numbers in data science programs. This would lead to believe that data and analytics area recent phenomenon. Indeed, there are convincing reasons that show analytics is more important and relevant than ever. However, the underlying idea of analytics – the urge to understand the nature of our reality and to act accordingly – is as old as humanity itself.
Information storage in DNA is the cornerstone of biology. Interestingly, prokaryotes can store information in specific loci in their DNA to remember encounters with invaders (such as bacteriophages--viruses that infect bacteria). Short samples of DNA from invaders are inserted as "spacers" into the CRISPR array. The array thus contains samples of DNA invaders in a defined locus that is recognized by Cas proteins that further process this information. This enables bacteria to adaptively and specifically respond to invading DNA that they have experienced before.
By way of explaining how a brain works logically, human associative memory is modeled with logical and memory neurons, corresponding to standard digital circuits. The resulting cognitive architecture incorporates basic psychological elements such as short term and long term memory. Novel to the architecture are memory searches using cues chosen pseudorandomly from short term memory. Recalls alternated with sensory images, many tens per second, are analyzed subliminally as an ongoing process, to determine a direction of attention in short term memory.
