Virtual Memory

  • Essentially treating memory like a cache for dish
    • Contents are a dynmaic subset of of prgrams address space
      • Meaning that each program is assigned an address space and that content is capable of change
  • Programs use virtual addresses (VA)
    • 0 -> 2^N-1
  • Memory uses physical addresses (PA)
    • 0 -> 2^M-1
    • 2^M is max physical memory machines support
  • VA => PA at page granulairty/scale (VP => PP)
  • Multiprogramming is a use of VM
    • Each process is given 2N bytes of address space
    • System maps VPs from different process to different PPs
      • This in turn prevents process from reading/writing each others memory
  • Interprocess Communication is a use of VM in which map VPs in different processes to same PPs
  • Protection is the mechanism to implement page-level protection

Published:

  • Supervised Learning algorithms require a target output
    • As opposed to unsupervised in which has no target output
    • Reinforcement is gives feedback
  • Underfitting can be a result of having a lack of hidden neurons or lack of data
  • Overtraining can be a result of too many hidden neurons
  • Each neuron has many inputs but only one output
  • Activation layer of hidden layer must be nonlinear
    • Other layers (I/O) can be linear

Throughout the significantly rapid developing history of Artifical Intelligence, embedded human essence remained at the core of cornerstone technology. The inclsuion of the Artifical Neural Network attempted to mimic the decision process of the human mind, ergo, giving binary machines the power of human-like thinking.
