joint training optimizes all parameters simultaneously by taking both the wide and deep part as well as the weights of their sum into account at training time.

The wide component and deep component are combined using a weighted sum of their output log odds as the pre-diction, which is then fed to one common logistic loss function for joint training.

difficult to learn effective low-dimensional representations for queries and items when the underlying query-item matrix is sparse and high-rank, such as users with specific preferences or niche items with a narrow appeal.

Logistic regression is a binary classification method. It can be modelled as a function that can take in any number of inputs and constrain the output to be between 0 and 1. This means, we can think of Logistic Regression as a one-layer neural network.

As previously stated, L2 regularization only shrinks the weights to values close to 0, rather than actually being 0. On the other hand, L1 regularization shrinks the values to 0.
Fighting Overfitting With L1 or L2 Regularization: Which One Is Better? - neptune.ai
L1 regularization is computationally more expensive, because it cannot be solved in terms of matrix math.
Fighting Overfitting With L1 or L2 Regularization: Which One Is Better? - neptune.ai
L1 regularization uses Manhattan distances to arrive at a single point, so there are many routes that can be taken to arrive at a point. L2 regularization uses Euclidean distances, which will tell you the fastest way to get to a point.
Fighting Overfitting With L1 or L2 Regularization: Which One Is Better? - neptune.ai
L1 regularization is more robust than L2 regularization for a fairly obvious reason. L2 regularization takes the square of the weights, so the cost of outliers present in the data increases exponentially. L1 regularization takes the absolute values of the weights, so the cost only increases linearly.
Fighting Overfitting With L1 or L2 Regularization: Which One Is Better? - neptune.ai
L2 regularization, or the L2 norm, or Ridge (in regression problems), combats overfitting by forcing weights to be small, but not making them exactly 0.
Fighting Overfitting With L1 or L2 Regularization: Which One Is Better? - neptune.ai
Essentially, when we use L1 regularization, we are penalizing the absolute value of the weights.

The algorithm will continue to make steps towards the global minimum of a convex function and the local minimum as long as the number of iterations (n_iters) are sufficient enough for gradient descent to reach the global minimum.
Fighting Overfitting With L1 or L2 Regularization: Which One Is Better? - neptune.ai
We use regularization because we want to add some bias into our model to prevent it overfitting to our training data.

“Regularization is any modification we make to a learning algorithm that is intended to reduce its generalization error but not its training error.”
