Question
[default - edit me]
Python is a high-level programming language, which means it takes care of many low-level tasks for you so you can focus on solving problems. For example, when you assign a value to a variable, Python deletes the variable automatically when it’s no longer needed, sparing you from having to manage memory. Every language has unique features that lead to charac- teristic programming styles and philosophies. Python focuses on simplicity, readability, and getting the job done.

 #artificial-intelligence #emotion-machine #minsky In one kind of block (which Freud calls "repression"), an impulse is blocked at an early stage—without the thinker becoming aware of this. However, repressed ideas can still persist—and may be expressed in elusive disguises—by changing the manner in which they're described (so that the Censors no longer can recognize them). Freud used the term sublimation for this, but we sometimes call this "rationalizing."

 #artificial-intelligence #emotion-machine #minsky William Calvin and George Ojeman 1994: "Modern discussions of consciousness . . . usually include such aspects of mental life as focusing your attention, things that you didn't know you knew, mental rehearsal, imagery, thinking, decision making, aware- ness, altered states of consciousness, voluntary actions, subliminal priming, the development of the concept of self in children, and the narratives we tell ourselves when awake or dreaming."

 #artificial-intelligence #behaviourism #emotion-machine #minsky Which features should be remembered?When you learn a new way to tie a knot, your Ifs should not include the time when you learned it, or that rule will never apply again. Thus, if a description is too specific, it will rarely match new situations—but if a description is too general, then it will match too many of them

A lucky guess might produce one such step, but to find an effective sequence of them, a random search would take far too long

 #artificial-intelligence #emotion-machine #minsky people construct synthetic perceptions inside their heads—and for this, I have coined the word umu- lus by combining stimulus and simulate. Thus in Chapter 3-8, I described how I used a simulus of Professor Challenger to disturb me enough to keep myself from falling asleep. To accomplish this, one might try to imagine all the details of such a scene; however, it might be enough merely to represent the high-level abstraction that there was a sneer on my rival's face—without constructing any other low-level details of that imagined simulus.
