ELI5: Hidden Markov Model

The Simple Explanation of "Hidden Markov Model"

Alright kiddo, let’s imagine you’re playing a game of hide and seek! 🕵️‍♂️

Now, you’re the seeker, and your friend is hiding. You don’t know exactly where they are, but you know they’re in one of a few spots, like behind the couch, under the bed, or in the closet. Every time you look in a spot, you can only get a clue — like a sound or a shadow — that tells you where they might be.

A Hidden Markov Model (HMM) is like playing a very smart version of hide and seek. Let’s break it down:

  • Hidden means you can’t see exactly where your friend is (like when you don’t know which spot they’re hiding in).
  • Markov is a fancy word that means every clue you get helps you guess where they might be next. So, if you hear a giggle under the bed, you might think they’ll stay close by!
  • Model means you’re using all the clues you gather to figure out what’s happening, like a detective.

So, each time you find a clue, the HMM helps you predict where your friend will hide next, based on where they were before and the sound they made. It’s like using clues to guess the next move in a fun game!

In real life, HMMs help computers figure out things like what words you might say next or where the weather will go. It’s like a computer playing hide and seek with clues!

Pretty cool, right? Want to play another round of hide and seek using clues? 😄
