Linear regression is used to model the relationship between two variables, where one variable (the dependent variable) is predicted based on the other variable (the independent variable). The equation for linear regression is Y = mX + b, where Y is the dependent variable, X is the independent variable, m is the slope of the line, and b is the y-intercept. Key moments: 00:02 Linear regression is crucial for understanding machine learning concepts as mathematics forms the foundation, making it essential to grasp the relationship between variables for prediction purposes. -Importance of mathematics in machine learning concepts and its correlation explained. -Explanation of linear regression and the relationship between dependent and independent variables. -Collecting and cleaning data for predicting pizza prices using linear regression. 04:01 Understanding linear equations and the concept of dependent and independent variables is crucial in mathematical calculations. Linear regression involves calculating the values of dependent and independent variables for further analysis. -Calculation of dependent and independent variables in linear equations is foundational for mathematical analysis and modeling. -Exploring the concept of linear regression and its application in mathematical calculations for predictive modeling. -Visualizing data through graphs to understand the intersection of values and facilitate easier analysis and interpretation. 10:25 Understanding linear regression concepts involves refining and cleaning data to reduce errors, even though some errors may still occur due to outliers in the data. -Importance of data refinement in reducing errors and outliers in linear regression analysis. -Challenges of errors in linear regression due to outliers and the need for data cleaning for accurate predictions.

[@ahsenhamid4990]

please double-check your definition of outliers. outliers are data points that deviate considerably from the average value of a group of statistics. Every point that deviates from the estimated fit line is not necessarily an outlier.

With Reference to 9:43 when new pizza size is 20, predicted price is 28, why not 26 (10*2 --> 13 *2)?

sir mujhe ye samajh nahi aaya agar 10 inches ka pizza hai to 13$ ka hoga or 20 inches ka pizza hai to 28$ ka kayse hoga. agar koi bta sakta hai to bta do yaar. mujhe ye samajh nahi aaya abhi tak. or ha mai ye nhi kah raha hun ke galat hai ye but bata do yaar kayse hua ye

[@RajdeepSingh-pr3xv]

Apke Hisab se 10 inch ka agar 13$ ka hai to 20 inch ka 26$ ka hona chahiye... Yhi hai apka doubt... Dekho.... Pizza hota round shape ka esliye uska price uske area ke hisab se hoga aur agar ham 10 cm diameter le aur fir 20 cm diameter le to area double nhii ayega balki jyada ayega esiliye....

[@rizztravelstories]

sir if the question is given in radius instead of diameter should we convert it to diameter before calculating

[@namitak7706]

Thank you !

Hello sir, I have one question that every time we'll calculate the linear regression so we have to calculate mean, deviation , product and square.

[@UdaiKs]

Sir please create videos on Python Dashboard i.e Plotly & Dash.

[@shadowofdreams248]

How the slope is equal to the division of sum of product of deviations and sum of square of deviations?? How slope becomes equal to it

[@AbdurRahim-zi9jl]

Bhai, x ka value zero kaha li hae sir ne. Wo to mean of x 10 li hae. Diameter zero kaha huwa. Samajh nehi aya. Pls guide me if you understood. Thanks
