        "# Dropout\n",
        "We know about the classical approach\n",
        "of regularizing statistical models\n",
        "by penalizing the $L_2$ norm of the weights.\n",
        "In probabilistic terms, we could justify this technique\n",
        "by arguing that we have assumed a prior belief\n",
        "that weights take values from\n",
        "a Gaussian distribution with mean zero.\n",
        "More intuitively, we might argue\n",
        "that we encouraged the model to spread out its weights\n",
        "among many features rather than depending too much\n",
        "on a small number of potentially spurious associations.\n",
        "\n",
        "## Overfitting Revisited\n",
        "\n",
        "Faced with more features than examples,\n",
        "linear models tend to overfit.\n",
        "But given more examples than features,\n",
        "we can generally count on linear models not to overfit.\n",
        "Unfortunately, the reliability with which\n",
        "linear models generalize comes at a cost.\n",
        "Naively applied, linear models do not take\n",
        "into account interactions among features.\n",
        "For every feature, a linear model must assign\n",
        "either a positive or a negative weight, ignoring context.\n",
        "\n",
        "In traditional texts, this fundamental tension\n",
        "between generalizability and flexibility\n",
        "is described as the *bias-variance tradeoff*.\n",
        "Linear models have high bias: they can only represent a small class of functions.\n",
        "However, these models have low variance: they give similar results\n",
        "across different random samples of the data.\n",
        "\n",
        "Deep neural networks inhabit the opposite\n",
        "end of the bias-variance spectrum.\n",
        "Unlike linear models, neural networks\n",
        "are not confined to looking at each feature individually.\n",
        "They can learn interactions among groups of features.\n",
        "For example, they might infer that\n",
        "“Nigeria” and “Western Union” appearing\n",
        "together in an email indicates spam\n",
        "but that separately they do not.\n",
        "\n",
        "Even when we have far more examples than features,\n",
        "deep neural networks are capable of overfitting.\n",
        "In 2017, a group of researchers demonstrated\n",
        "the extreme flexibility of neural networks\n",
        "by training deep nets on randomly-labeled images.\n",
        "Despite the absence of any true pattern\n",
        "linking the inputs to the outputs,\n",
        "they found that the neural network optimized by stochastic gradient descent\n",
        "could label every image in the training set perfectly.\n",
        "Consider what this means.\n",
        "If the labels are assigned uniformly\n",
        "at random and there are 10 classes,\n",
        "then no classifier can do better\n",
        "than 10% accuracy on holdout data.\n",
        "The generalization gap here is a whopping 90%.\n",
        "If our models are so expressive that they\n",
        "can overfit this badly, then when should\n",
        "we expect them not to overfit?\n",
        "\n",
        "The mathematical foundations for\n",
        "the puzzling generalization properties\n",
        "of deep networks remain open research questions,\n",
        "and we encourage the theoretically-oriented\n",
        "reader to dig deeper into the topic.\n",
        "For now, we turn to the investigation of\n",
        "practical tools that tend to\n",
        "empirically improve the generalization of deep nets.\n",
        "\n",
        "## Robustness through Perturbations\n",
        "\n",
        "Let us think briefly about what we\n",
        "expect from a good predictive model.\n",
        "We want it to peform well on unseen data.\n",
        "Classical generalization theory\n",
        "suggests that to close the gap between\n",
        "train and test performance,\n",
        "we should aim for a simple model.\n",
        "Simplicity can come in the form\n",
        "of a small number of dimensions.\n",
        "\n",
        "In 1995, Christopher Bishop formalized\n",
        "this idea when he proved that training with input noise\n",
        "is equivalent to Tikhonov regularization :cite:`Bishop.1995`.\n",
        "This work drew a clear mathematical connection\n",
        "between the requirement that a function be smooth (and thus simple),\n",
        "and the requirement that it be resilient\n",
        "to perturbations in the input.\n",
        "\n",
        "Then, in 2014, Srivastava et al. :cite:`Srivastava.Hinton.Krizhevsky.ea.2014`\n",
        "developed a clever idea for how to apply Bishop's idea\n",
        "to the internal layers of a network, too.\n",
        "Namely, they proposed to inject noise\n",
        "into each layer of the network\n",
        "before calculating the subsequent layer during training.\n",
        "They realized that when training\n",
        "a deep network with many layers,\n",
        "injecting noise enforces smoothness just on the input-output mapping.\n",
        "\n",
        "Their idea, called *dropout*, involves\n",
        "injecting noise while computing\n",
        "each internal layer during forward propagation,\n",
        "and it has become a standard technique\n",
        "for training neural networks.\n",
        "The method is called *dropout* because we literally\n",
        "*drop out* some neurons during training.\n",
        "Throughout training, on each iteration,\n",
        "standard dropout consists of zeroing out\n",
        "some fraction of the nodes in each layer\n",
        "before calculating the subsequent layer.\n",
        "\n",
        "To be clear, we are imposing\n",
        "our own narrative with the link to Bishop.\n",
        "The original paper on dropout\n",
        "offers intuition through a surprising\n",
        "analogy to sexual reproduction.\n",
        "The authors argue that neural network overfitting\n",
        "is characterized by a state in which\n",
        "each layer relies on a specifc\n",
        "pattern of activations in the previous layer,\n",
        "calling this condition *co-adaptation*.\n",
        "Dropout, they claim, breaks up co-adaptation\n",
        "just as sexual reproduction is argued to\n",
        "break up co-adapted genes.\n",
        "\n",
        "The key challenge then is how to inject this noise.\n",
        "One idea is to inject the noise in an *unbiased* manner\n",
        "so that the expected value of each layer---while fixing\n",
        "the others---equals to the value it would have taken absent noise.\n",
        "\n",
        "In Bishop's work, he added Gaussian noise\n",
        "to the inputs to a linear model.\n",
        "At each training iteration, he added noise\n",
        "sampled from a distribution with mean zero\n",
        "$\\epsilon \\sim \\mathcal{N}(0,\\sigma^2)$ to the input $\\mathbf{x}$,\n",
        "yielding a perturbed point $\\mathbf{x}' = \\mathbf{x} + \\epsilon$.\n",
        "In expectation, $E[\\mathbf{x}'] = \\mathbf{x}$.\n",
        "\n",
        "In standard dropout regularization,\n",
        "one debiases each layer by normalizing\n",
        "by the fraction of nodes that were retained (not dropped out).\n",
        "In other words,\n",
        "with *dropout probability* $p$,\n",
        "each intermediate activation $h$ is replaced by\n",
        "a random variable $h'$ as follows:\n",
        "\n",
        "$$\n",
        "\\begin{aligned}\n",
        "h' =\n",
        "\\begin{cases}\n",
        "    0 & \\text{ with probability } p \\\\\n",
        "    \\frac{h}{1-p} & \\text{ otherwise}\n",
        "\\end{cases}\n",
        "\\end{aligned}\n",
        "$$\n",
        "\n",
        "By design, the expectation remains unchanged, i.e., $E[h'] = h$.\n",
        "\n",
        "## Dropout in Practice\n",
        "\n",
        "Recall the MLP with a hidden layer and 5 hidden units.\n",
        "When we apply dropout to a hidden layer,\n",
        "zeroing out each hidden unit with probability $p$,\n",
        "the result can be viewed as a network\n",
        "containing only a subset of the original neurons.\n",
        "In the following figure, $h_2$ and $h_5$ are removed.\n",
        "Consequently, the calculation of the outputs\n",
        "no longer depends on $h_2$ or $h_5$\n",
        "and their respective gradient also vanishes\n",
        "when performing backpropagation.\n",
        "In this way, the calculation of the output layer\n",
        "cannot be overly dependent on any\n",
        "one element of $h_1, \\ldots, h_5$.\n",
        "\n",
        "Typically, we disable dropout at test time.\n",
        "Given a trained model and a new example,\n",
        "we do not drop out any nodes\n",
        "and thus do not need to normalize.\n",
        "However, there are some exceptions:\n",
        "some researchers use dropout at test time as a heuristic\n",
        "for estimating the *uncertainty* of neural network predictions:\n",
        "if the predictions agree across many different dropout masks,\n",
        "then we might say that the network is more confident.\n",
        "\n",
        "## Implementation from Scratch\n",
        "\n",
        "To implement the dropout function for a single layer,\n",
        "we must draw as many samples\n",
        "from a Bernoulli (binary) random variable\n",
        "as our layer has dimensions,\n",
        "where the random variable takes value $1$ (keep)\n",
        "with probability $1-p$ and $0$ (drop) with probability $p$.\n",
        "One easy way to implement this is to first draw samples\n",
        "from the uniform distribution $U[0, 1]$.\n",
        "Then we can keep those nodes for which the corresponding\n",
        "sample is greater than $p$, dropping the rest.\n",
        "\n",
        "In the following code, we (**implement a `dropout_layer` function\n",
        "that drops out the elements in the tensor input `X`\n",
        "with probability `dropout`**),\n",
        "rescaling the remainder as described above:\n",
        "dividing the survivors by `1.0-dropout`.\n"
