Friday Squid Blogging: US Naval Ship Attacked by Squid in 1978

Interesting story:

USS Stein was underway when her anti-submarine sonar gear suddenly stopped working. On returning to port and putting the ship in a drydock, engineers observed many deep scratches in the sonar dome’s rubber “NOFOUL” coating. In some areas, the coating was described as being shredded, with rips up to four feet long. Large claws were left embedded at the bottom of most of the scratches.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

Friday Squid Blogging: Pet Squid Simulation

From Hackaday.com, this is a neural network simulation of a pet squid.

Autonomous Behavior:

  • The squid moves autonomously, making decisions based on his current state (hunger, sleepiness, etc.).
  • Implements a vision cone for food detection, simulating realistic foraging behavior.
  • Neural network can make decisions and form associations.
  • Weights are analysed, tweaked and trained by Hebbian learning algorithm.
  • Experiences from short-term and long-term memory can influence decision-making.
  • Squid can create new neurons in response to his environment (Neurogenesis)
