<h1 id="Convolutional-Neural-Networks:-Step-by-Step">Convolutional Neural Networks: Step by Step<a class="anchor-link" href="#Convolutional-Neural-Networks:-Step-by-Step">&#182;</a></h1><p>Welcome to Course 4's first assignment! In this assignment, you will implement convolutional (CONV) and pooling (POOL) layers in numpy, including both forward propagation and (optionally) backward propagation.</p>
<p><strong>Notation</strong>:</p>
<ul>
<li>Superscript $[l]$ denotes an object of the $l^{th}$ layer. <ul>
<li>Example: $a^{[4]}$ is the $4^{th}$ layer activation. $W^{[5]}$ and $b^{[5]}$ are the $5^{th}$ layer parameters.</li>
</ul>
</li>
</ul>
<ul>
<li>Superscript $(i)$ denotes an object from the $i^{th}$ example. <ul>
<li>Example: $x^{(i)}$ is the $i^{th}$ training example input.</li>
</ul>
</li>
</ul>
<ul>
<li>Subscript $i$ denotes the $i^{th}$ entry of a vector.<ul>
<li>Example: $a^{[l]}_i$ denotes the $i^{th}$ entry of the activations in layer $l$, assuming this is a fully connected (FC) layer.</li>
</ul>
</li>
</ul>
<ul>
<li>$n_H$, $n_W$ and $n_C$ denote respectively the height, width and number of channels of a given layer. If you want to reference a specific layer $l$, you can also write $n_H^{[l]}$, $n_W^{[l]}$, $n_C^{[l]}$. </li>
<li>$n_{H_{prev}}$, $n_{W_{prev}}$ and $n_{C_{prev}}$ denote respectively the height, width and number of channels of the previous layer. If referencing a specific layer $l$, this could also be denoted $n_H^{[l-1]}$, $n_W^{[l-1]}$, $n_C^{[l-1]}$. </li>
</ul>
<p>We assume that you are already familiar with <code>numpy</code> and/or have completed the previous courses of the specialization. Let's get started!</p>

<li>clarified example used for padding function.  Updated starter code for padding function.</li>
<li><code>conv_forward</code> has additional hints to help students if they're stuck.</li>
<li><code>conv_forward</code> places code for <code>vert_start</code> and <code>vert_end</code> within the <code>for h in range(...)</code> loop; to avoid redundant calculations.  Similarly updated <code>horiz_start</code> and <code>horiz_end</code>.  <strong>Thanks to our mentor Kevin Brown for pointing this out.</strong></li>
<li><code>conv_forward</code> breaks down the <code>Z[i, h, w, c]</code> single line calculation into 3 lines, for clarity.</li>
<li><code>conv_forward</code> test case checks that students don't accidentally use n_H_prev instead of n_H, use n_W_prev instead of n_W, and don't accidentally swap n_H with n_W</li>
<li><code>pool_forward</code> properly nests calculations of <code>vert_start</code>, <code>vert_end</code>, <code>horiz_start</code>, and <code>horiz_end</code> to avoid redundant calculations.</li>
<li>`pool_forward' has two new test cases that check for a correct implementation of stride (the height and width of the previous layer's activations should be large enough relative to the filter dimensions so that a stride can take place).  </li>
<li><code>conv_backward</code>: initialize <code>Z</code> and <code>cache</code> variables within unit test, to make it independent of unit testing that occurs in the <code>conv_forward</code> section of the assignment.</li>
<li><strong>Many thanks to our course mentor, Paul Mielke, for proposing these test cases.</strong></li>

<h2 id="2---Outline-of-the-Assignment">2 - Outline of the Assignment<a class="anchor-link" href="#2---Outline-of-the-Assignment">&#182;</a></h2><p>You will be implementing the building blocks of a convolutional neural network! Each function you will implement will have detailed instructions that will walk you through the steps needed:</p>
<ul>
<li>Convolution functions, including:<ul>
<li>Zero Padding</li>
<li>Convolve window </li>
<li>Convolution forward</li>
<li>Convolution backward (optional)</li>
</ul>
</li>
<li>Pooling functions, including:<ul>
<li>Pooling forward</li>
<li>Create mask </li>
<li>Distribute value</li>
<li>Pooling backward (optional)</li>
</ul>
</li>
</ul>
<p>This notebook will ask you to implement these functions from scratch in <code>numpy</code>. In the next notebook, you will use the TensorFlow equivalents of these functions to build the following model:</p>
<p><strong>Note</strong> that for every forward function, there is its corresponding backward equivalent. Hence, at every step of your forward module you will store some parameters in a cache. These parameters are used to compute gradients during backpropagation.</p>

<h2 id="3---Convolutional-Neural-Networks">3 - Convolutional Neural Networks<a class="anchor-link" href="#3---Convolutional-Neural-Networks">&#182;</a></h2><p>Although programming frameworks make convolutions easy to use, they remain one of the hardest concepts to understand in Deep Learning. A convolution layer transforms an input volume into an output volume of different size, as shown below.</p>
<p>In this part, you will build every step of the convolution layer. You will first implement two helper functions: one for zero padding and the other for computing the convolution function itself.</p>

<h3 id="3.1---Zero-Padding">3.1 - Zero-Padding<a class="anchor-link" href="#3.1---Zero-Padding">&#182;</a></h3><p>Zero-padding adds zeros around the border of an image:</p>
<p>The main benefits of padding are the following:</p>
<ul>
<li><p>It allows you to use a CONV layer without necessarily shrinking the height and width of the volumes. This is important for building deeper networks, since otherwise the height/width would shrink as you go to deeper layers. An important special case is the "same" convolution, in which the height/width is exactly preserved after one layer.</p>
</li>
<li><p>It helps us keep more of the information at the border of an image. Without padding, very few values at the next layer would be affected by pixels as the edges of an image.</p>
</li>
</ul>
<p><strong>Exercise</strong>: Implement the following function, which pads all the images of a batch of examples X with zeros. <a href="https://docs.scipy.org/doc/numpy/reference/generated/numpy.pad.html">Use np.pad</a>. Note if you want to pad the array "a" of shape $(5,5,5,5,5)$ with <code>pad = 1</code> for the 2nd dimension, <code>pad = 3</code> for the 4th dimension and <code>pad = 0</code> for the rest, you would do:</p>

<h3 id="3.2---Single-step-of-convolution">3.2 - Single step of convolution<a class="anchor-link" href="#3.2---Single-step-of-convolution">&#182;</a></h3><p>In this part, implement a single step of convolution, in which you apply the filter to a single position of the input. This will be used to build a convolutional unit, which:</p>
<ul>
<li>Takes an input volume </li>
<li>Applies a filter at every position of the input</li>
<li>Outputs another volume (usually of different size)</li>
</ul>
<p>In a computer vision application, each value in the matrix on the left corresponds to a single pixel value, and we convolve a 3x3 filter with the image by multiplying its values element-wise with the original matrix, then summing them up and adding a bias. In this first step of the exercise, you will implement a single step of convolution, corresponding to applying a filter to just one of the positions to get a single real-valued output.</p>
<p>Later in this notebook, you'll apply this function to multiple positions of the input to implement the full convolutional operation.</p>
<p><strong>Exercise</strong>: Implement conv_single_step(). <a href="https://docs.scipy.org/doc/numpy-1.13.0/reference/generated/numpy.sum.html">Hint</a>.</p>

<h3 id="3.3---Convolutional-Neural-Networks---Forward-pass">3.3 - Convolutional Neural Networks - Forward pass<a class="anchor-link" href="#3.3---Convolutional-Neural-Networks---Forward-pass">&#182;</a></h3><p>In the forward pass, you will take many filters and convolve them on the input. Each 'convolution' gives you a 2D matrix output. You will then stack these outputs to get a 3D volume:</p>
<p><strong>Exercise</strong>: 
Implement the function below to convolve the filters <code>W</code> on an input activation <code>A_prev</code>.<br>
This function takes the following inputs:</p>
<ul>
<li><code>A_prev</code>, the activations output by the previous layer (for a batch of m inputs); </li>
<li>Weights are denoted by <code>W</code>.  The filter window size is <code>f</code> by <code>f</code>.</li>
<li>The bias vector is <code>b</code>, where each filter has its own (single) bias. </li>
</ul>
<p>Finally you also have access to the hyperparameters dictionary which contains the stride and the padding.</p>
<p><strong>Hint</strong>:</p>
<ol>
<li>To select a 2x2 slice at the upper left corner of a matrix "a_prev" (shape (5,5,3)), you would do:<div class="highlight"><pre><span></span><span class="n">a_slice_prev</span> <span class="o">=</span> <span class="n">a_prev</span><span class="p">[</span><span class="mi">0</span><span class="p">:</span><span class="mi">2</span><span class="p">,</span><span class="mi">0</span><span class="p">:</span><span class="mi">2</span><span class="p">,:]</span>
</pre></div>
Notice how this gives a 3D slice that has height 2, width 2, and depth 3.  Depth is the number of channels.<br>
This will be useful when you will define <code>a_slice_prev</code> below, using the <code>start/end</code> indexes you will define.</li>
<li>To define a_slice you will need to first define its corners <code>vert_start</code>, <code>vert_end</code>, <code>horiz_start</code> and <code>horiz_end</code>. This figure may be helpful for you to find out how each of the corner can be defined using h, w, f and s in the code below.</li>
</ol>
<strong>Reminder</strong>:
The formulas relating the output shape of the convolution to the input shape is:
$$ n_H = \lfloor \frac{n_{H_{prev}} - f + 2 \times pad}{stride} \rfloor +1 $$
$$ n_W = \lfloor \frac{n_{W_{prev}} - f + 2 \times pad}{stride} \rfloor +1 $$
$$ n_C = \text{number of filters used in the convolution}$$</p>
<p>For this exercise, we won't worry about vectorization, and will just implement everything with for-loops.</p>

<li>You will want to use array slicing (e.g.<code>varname[0:1,:,3:5]</code>) for the following variables:<br>
<code>a_prev_pad</code> ,<code>W</code>, <code>b</code><br>
Copy the starter code of the function and run it outside of the defined function, in separate cells.<br>
Check that the subset of each array is the size and dimension that you're expecting.  </li>
<li>To decide how to get the vert_start, vert_end; horiz_start, horiz_end, remember that these are indices of the previous layer.<br>
Draw an example of a previous padded layer (8 x 8, for instance), and the current (output layer) (2 x 2, for instance).<br>
The output layer's indices are denoted by <code>h</code> and <code>w</code>.  </li>
<li>Make sure that <code>a_slice_prev</code> has a height, width and depth.</li>
<li>Remember that <code>a_prev_pad</code> is a subset of <code>A_prev_pad</code>.<br>
Think about which one should be used within the for loops.</li>

<h2 id="4---Pooling-layer">4 - Pooling layer<a class="anchor-link" href="#4---Pooling-layer">&#182;</a></h2><p>The pooling (POOL) layer reduces the height and width of the input. It helps reduce computation, as well as helps make feature detectors more invariant to its position in the input. The two types of pooling layers are:</p>
<ul>
<li><p>Max-pooling layer: slides an ($f, f$) window over the input and stores the max value of the window in the output.</p>
</li>
<li><p>Average-pooling layer: slides an ($f, f$) window over the input and stores the average value of the window in the output.</p>
</li>
</ul>
<p>These pooling layers have no parameters for backpropagation to train. However, they have hyperparameters such as the window size $f$. This specifies the height and width of the $f \times f$ window you would compute a <em>max</em> or <em>average</em> over.</p>
<h3 id="4.1---Forward-Pooling">4.1 - Forward Pooling<a class="anchor-link" href="#4.1---Forward-Pooling">&#182;</a></h3><p>Now, you are going to implement MAX-POOL and AVG-POOL, in the same function.</p>
<p><strong>Exercise</strong>: Implement the forward pass of the pooling layer. Follow the hints in the comments below.</p>
<p><strong>Reminder</strong>:
As there's no padding, the formulas binding the output shape of the pooling to the input shape is:</p>
$$ n_H = \lfloor \frac{n_{H_{prev}} - f}{stride} \rfloor +1 $$$$ n_W = \lfloor \frac{n_{W_{prev}} - f}{stride} \rfloor +1 $$$$ n_C = n_{C_{prev}}$$

<h2 id="5---Backpropagation-in-convolutional-neural-networks-(OPTIONAL-/-UNGRADED)">5 - Backpropagation in convolutional neural networks (OPTIONAL / UNGRADED)<a class="anchor-link" href="#5---Backpropagation-in-convolutional-neural-networks-(OPTIONAL-/-UNGRADED)">&#182;</a></h2><p>In modern deep learning frameworks, you only have to implement the forward pass, and the framework takes care of the backward pass, so most deep learning engineers don't need to bother with the details of the backward pass. The backward pass for convolutional networks is complicated. If you wish, you can work through this optional portion of the notebook to get a sense of what backprop in a convolutional network looks like.</p>
<p>When in an earlier course you implemented a simple (fully connected) neural network, you used backpropagation to compute the derivatives with respect to the cost to update the parameters. Similarly, in convolutional neural networks you can calculate the derivatives with respect to the cost in order to update the parameters. The backprop equations are not trivial and we did not derive them in lecture, but we will briefly present them below.</p>
<h3 id="5.1---Convolutional-layer-backward-pass">5.1 - Convolutional layer backward pass<a class="anchor-link" href="#5.1---Convolutional-layer-backward-pass">&#182;</a></h3><p>Let's start by implementing the backward pass for a CONV layer.</p>
<h4 id="5.1.1---Computing-dA:">5.1.1 - Computing dA:<a class="anchor-link" href="#5.1.1---Computing-dA:">&#182;</a></h4><p>This is the formula for computing $dA$ with respect to the cost for a certain filter $W_c$ and a given training example:</p>
$$ dA += \sum _{h=0} ^{n_H} \sum_{w=0} ^{n_W} W_c \times dZ_{hw} \tag{1}$$<p>Where $W_c$ is a filter and $dZ_{hw}$ is a scalar corresponding to the gradient of the cost with respect to the output of the conv layer Z at the hth row and wth column (corresponding to the dot product taken at the ith stride left and jth stride down). Note that at each time, we multiply the the same filter $W_c$ by a different dZ when updating dA. We do so mainly because when computing the forward propagation, each filter is dotted and summed by a different a_slice. Therefore when computing the backprop for dA, we are just adding the gradients of all the a_slices.</p>
<p>In code, inside the appropriate for-loops, this formula translates into:</p>

</pre></div>
<h4 id="5.1.2---Computing-dW:">5.1.2 - Computing dW:<a class="anchor-link" href="#5.1.2---Computing-dW:">&#182;</a></h4><p>This is the formula for computing $dW_c$ ($dW_c$ is the derivative of one filter) with respect to the loss:</p>
$$ dW_c  += \sum _{h=0} ^{n_H} \sum_{w=0} ^ {n_W} a_{slice} \times dZ_{hw}  \tag{2}$$<p>Where $a_{slice}$ corresponds to the slice which was used to generate the activation $Z_{ij}$. Hence, this ends up giving us the gradient for $W$ with respect to that slice. Since it is the same $W$, we will just add up all such gradients to get $dW$.</p>
<p>In code, inside the appropriate for-loops, this formula translates into:</p>

<h4 id="5.1.3---Computing-db:">5.1.3 - Computing db:<a class="anchor-link" href="#5.1.3---Computing-db:">&#182;</a></h4><p>This is the formula for computing $db$ with respect to the cost for a certain filter $W_c$:</p>
$$ db = \sum_h \sum_w dZ_{hw} \tag{3}$$<p>As you have previously seen in basic neural networks, db is computed by summing $dZ$. In this case, you are just summing over all the gradients of the conv output (Z) with respect to the cost.</p>
<p>In code, inside the appropriate for-loops, this formula translates into:</p>
<div class="highlight"><pre><span></span><span class="n">db</span><span class="p">[:,:,:,</span><span class="n">c</span><span class="p">]</span> <span class="o">+=</span> <span class="n">dZ</span><span class="p">[</span><span class="n">i</span><span class="p">,</span> <span class="n">h</span><span class="p">,</span> <span class="n">w</span><span class="p">,</span> <span class="n">c</span><span class="p">]</span>

<h2 id="5.2-Pooling-layer---backward-pass">5.2 Pooling layer - backward pass<a class="anchor-link" href="#5.2-Pooling-layer---backward-pass">&#182;</a></h2><p>Next, let's implement the backward pass for the pooling layer, starting with the MAX-POOL layer. Even though a pooling layer has no parameters for backprop to update, you still need to backpropagation the gradient through the pooling layer in order to compute gradients for layers that came before the pooling layer.</p>
<h3 id="5.2.1-Max-pooling---backward-pass">5.2.1 Max pooling - backward pass<a class="anchor-link" href="#5.2.1-Max-pooling---backward-pass">&#182;</a></h3><p>Before jumping into the backpropagation of the pooling layer, you are going to build a helper function called <code>create_mask_from_window()</code> which does the following:</p>
$$ X = \begin{bmatrix}
1 && 3 \\
4 && 2
\end{bmatrix} \quad \rightarrow  \quad M =\begin{bmatrix}
0 && 0 \\
1 && 0
\end{bmatrix}\tag{4}$$<p>As you can see, this function creates a "mask" matrix which keeps track of where the maximum of the matrix is. True (1) indicates the position of the maximum in X, the other entries are False (0). You'll see later that the backward pass for average pooling will be similar to this but using a different mask.</p>
<p><strong>Exercise</strong>: Implement <code>create_mask_from_window()</code>. This function will be helpful for pooling backward. 
Hints:</p>
<ul>
<li><a href="">np.max()</a> may be helpful. It computes the maximum of an array.</li>
<li>If you have a matrix X and a scalar x: <code>A = (X == x)</code> will return a matrix A of the same size as X such that:
<pre><code>A[i,j] = True if X[i,j] = x
A[i,j] = False if X[i,j] != x</code></pre>
</li>
<li>Here, you don't need to consider cases where there are several maxima in a matrix.</li>

<p>Why do we keep track of the position of the max? It's because this is the input value that ultimately influenced the output, and therefore the cost. Backprop is computing gradients with respect to the cost, so anything that influences the ultimate cost should have a non-zero gradient. So, backprop will "propagate" the gradient back to this particular input value that had influenced the cost.</p>

In average pooling, every element of the input window has equal influence on the output. So to implement backprop, you will now implement a helper function that reflects this.</p>
<p>For example if we did average pooling in the forward pass using a 2x2 filter, then the mask you'll use for the backward pass will look like: 
$$ dZ = 1 \quad \rightarrow  \quad dZ =\begin{bmatrix}
1/4 && 1/4 \\
1/4 && 1/4
\end{bmatrix}\tag{5}$$</p>
<p>This implies that each position in the $dZ$ matrix contributes equally to output because in the forward pass, we took an average.</p>

You should use an <code>if/elif</code> statement to see if the mode is equal to <code>'max'</code> or <code>'average'</code>. If it is equal to 'average' you should use the <code>distribute_value()</code> function you implemented above to create a matrix of the same shape as <code>a_slice</code>.
