I read these things on the internet like

My model determines the future scope..."


My model gives accurate readings about what the score would be..."

What are these models? How are they designed?

    $\begingroup$ Good answers to this question may be very useful to the community. Context is not required to answer to this general question, which can be answered in a general way, with eventually specific examples to give a more intuitive idea of what a model could be. $\endgroup$ – nbro Nov 30 '17 at 0:25

  • $\begingroup$ @nbro Agreed (My thought was that at least specifying that the model is AI related reduces ambiguity, although it can be inferred via "accurate readings about what the score would be".) Thanks for the feedback and edit! $\endgroup$ – DukeZhou Nov 30 '17 at 19:23

A model is exactly what the name suggests. A simplified representation of a solution to a real life problem.

For example, if you think of a simple formula for a falling object you may not take into account real life variables such as the imperfections on the surface of the object, atmospheric conditions, the exact composition of the air the object is falling through and how it may affect friction. you just use a simple model to "model" the fall and get a reasonably accurate result. its a model, it doesnt have all the details. just like a model car wouldnt have all the details of a real car.

Here's a good read to get you started: https://en.wikipedia.org/wiki/Mathematical_model

  • $\begingroup$ "A simplified representation of a solution to a real life problem.": why is a model a representation of a solution? Are you sure? $\endgroup$ – nbro Nov 30 '17 at 0:23

    $\begingroup$ In the context of what the poster is asking it is a solution or a problem or just anything. I tried to explain in the rest of the post but it doesnt matter as I have a feeling this whole thread will be marked off-topic soon. $\endgroup$ – solarflare Nov 30 '17 at 0:42
  • $\begingroup$ These links might strengthen this answer: Model-based reasoning, Bayesian Networks, and Statistical Model $\endgroup$ – DukeZhou Dec 1 '17 at 16:01
