What is Neural Network, Unsupervise Learning, K means Clustering Algorithm…

- - - - Example Stock Market Predictions and Sales Forcasting
      - o/p from previous step is fed as input to the current step
      - Back Propogation
        
        Step 1 Each Node makes a guess about next node in the path step 2 if checks if the guess was correct , Nodes assign higher weights values to paths that lead to more correct guess and lower weights values to node paths that leads to incorrect guess step 3 for next data point , the nodes make new predictions using higher weight oaths and repeat step 1
- - - - Guassian Distribution
      - They are used to classiy data into different categories based on probability distribution
- - - - step 1 Import Library Step 2 Import data Set Step 3 Extracting independent varaibles step 4 From import k means( apply elbow method)
- - - - Gaussian Kernel
        
        used to perform transformation when there is no prior knowledge about data
      - Radial basis function
