Simple implementation of Gradient Descent using Python

	import numpy as np
	import matplotlib.pyplot as plt


	def gradientdescentoptimizer(param, c, learning_rate =0.01):
	# Forward Propagation
	param["cost"] = c[0][0] * param["w"] ** 2 + c[1][0] * param["w"] + c[2][0]
	# Backward Propagation
	param["dw"] = 2 * c[0][0] * param["w"] + c[1][0]
	# Update Omega

This is an example of using TensorFlow for simple Linear Regression of 1M points

	# imports
	import tensorflow as tf
	import numpy as np
	import pandas as pd
	import matplotlib.pyplot as plt

	# Create linear spaced million points
	xData = np.linspace(0.0, 10.0, 1000000, dtype=float)
	# Create million random points
	noise = np.random.randn(len(xData))
