Machine Learning From scratch | Part 1. Scaler, And Vector

Hello Every One Lets start with the very basic prerequisit of machine learning I wont be taelling you the why and what of machine learning rather lets see some simple maths which can be usefull in our journey of ml

Scaler And Vector

Two Statments

  1. I have Travelled 50Km
  2. I have travelled 50km in North-East direction

In first statment if you see we have only one value that is distance which i have travelled so it will be scaller (only one value)

In the second statment we have two things Distance and in which direction so this will be a vector (2 or more values)

In simple words one value is scaler and multiple values (dimentions) are vector

one more example

Lets say my temrature changes 2 unit

so here we know that temratture has changed by 2 unit and that only we know so it will be scaller

and my temprature increased 2 unit or decresed 2 unit

in this statment have 2 dementions temprature and directtion so this will be vector

There are plenty of scalar quantity examples, some of the common examples are:

  • Mass
  • Speed
  • Distance
  • Time
  • Area
  • Volume
  • Density
  • Temperature

Vector quantity examples are many, some of them are given below:

  • Linear momentum
  • Acceleration
  • Displacement
  • Momentum
  • Angular velocity
  • Force
  • Electric field
  • Polarization
