What is the difference between 'regular' linear regression and deep learning linear regression?

Question

I want to know the difference between linear regression in a regular machine learning analysis and linear regression in "deep learning" setting. What algorithms are used for linear regression in deep learning setting.

Answer 1

Assuming that by deep learning you meant more precisely neural networks: a vanilla fully connected feedforward neural network with only linear activation functions will perform linear regression, regardless of how many layers it has. One difference is that with a neural network one typically uses gradient descent, whereas with "normal" linear regression one uses the normal equation if possible (when the number of features isn't too huge).

Example of a fully connected feedforward neural network with no hidden layer and using a linear activation function (namely the identity activation function):

If you replace the activation function of the output layer with a sigmoid function, then the neural network performs logistic regression. If you replace the activation function of the output layer with a softmax function and add a few output units, then the neural network performs multiclass logistic regression: Difference between logistic regression and neural networks. If you replace the cost function with the hinge loss, then the neural network is an SVM optimized in its primal form: http://cs231n.github.io/linear-classify/.

Here is the example shown in the picture above programmed in TensorFlow:

Here is a code snippet that does not use any neural network libraries:

# From http://briandolhansky.com/blog/artificial-neural-networks-linear-regression-part-1
import matplotlib.pyplot as plt
import numpy as np

# Load the data and create the data matrices X and Y
# This creates a feature vector X with a column of ones (bias)
# and a column of car weights.
# The target vector Y is a column of MPG values for each car.
X_file = np.genfromtxt('mpg.csv', delimiter=',', skip_header=1)
N = np.shape(X_file)[0]
X = np.hstack((np.ones(N).reshape(N, 1), X_file[:, 4].reshape(N, 1)))
Y = X_file[:, 0]

# Standardize the input 
X[:, 1] = (X[:, 1]-np.mean(X[:, 1]))/np.std(X[:, 1])

# There are two weights, the bias weight and the feature weight
w = np.array([0, 0])

# Start batch gradient descent, it will run for max_iter epochs and have a step
# size eta
max_iter = 100
eta = 1E-3
for t in range(0, max_iter):
    # We need to iterate over each data point for one epoch
    grad_t = np.array([0., 0.])
    for i in range(0, N):
        x_i = X[i, :]
        y_i = Y[i]
        # Dot product, computes h(x_i, w)
        h = np.dot(w, x_i)-y_i
        grad_t += 2*x_i*h

    # Update the weights
    w = w - eta*grad_t
print "Weights found:",w

# Plot the data and best fit line
tt = np.linspace(np.min(X[:, 1]), np.max(X[:, 1]), 10)
bf_line = w[0]+w[1]*tt

plt.plot(X[:, 1], Y, 'kx', tt, bf_line, 'r-')
plt.xlabel('Weight (Normalized)')
plt.ylabel('MPG')
plt.title('ANN Regression on 1D MPG Data')

plt.savefig('mpg.png')

plt.show()

Answer 2

For regression, which for deep learning is nonlinear in most cases, final layer has 1 neuron with identity function and loss function we optimize is MSE, MAE instead of binary or categorical cross-entropy used for classification.
