Let us first import the necessary libraries and functions, and set plotting style.
In [1]:
import numpy as np
import numpy.random as npr
import tensorflow.keras as keras
import matplotlib.pyplot as plt
plt.style.use(‘ggplot’)

We first define the function $g(x) := \sin(10x)$, $x \in \mathbb{R}$.
In [2]:
a = 10
def g(x):
return np.sin(a*x)

We then generate the data $x^0,x^1,\ldots,x^{N-1}$ (we switch here to the convention of Python of starting indexation from $0$) from $\mathrm{Uniform}(0,1)$ and \begin{equation} y^i = g(x^i) + \varepsilon^i, \quad i=0,1\ldots,N-1, \end{equation} with iid $\varepsilon^i \sim N(0,0.1)$, $i = 0,1,\ldots,N-1$, for $N = 1\,000\,000$.
In [3]:
N = 1000000
var = 0.1
x = npr.uniform(0,1, (N,1))
eps = npr.normal(0, np.sqrt(var), (N,1))
y = g(x)+eps

Let us plot the first $1000$ samples:
In [4]:
N_sub = 1000
plt.plot(x[0:N_sub,], y[0:N_sub,], “bo”, markersize=3)
plt.xlabel(r”$x^i$”)
plt.ylabel(r”$y^i$”)
plt.show()



Now we specify the neural network \begin{equation} \widehat{g} \in \mathcal{N}_4(1,100,100,100,1; \mathrm{ReLU},\mathrm{ReLU},\mathrm{ReLU},\mathrm{Id}) \end{equation} using the Sequential model of Keras, and inspect the specification.
In [4]:
g_hat = keras.Sequential([
keras.layers.Dense(100, activation=”relu”, input_shape=(1,)),
keras.layers.Dense(100, activation=”relu”),
keras.layers.Dense(100, activation=”relu”),
keras.layers.Dense(1, activation=”linear”)
]
)
g_hat.summary()

We compile $\widehat{g}$ so that it will be trained using Adam to minimise squared loss.
In [5]:
g_hat.compile(optimizer=”adam”, loss=”mean_squared_error”)

WARNING:tensorflow:From /Users/blanka/anaconda3/lib/python3.7/site-packages/tensorflow/python/keras/utils/losses_utils.py:170: to_float (from tensorflow.python.ops.math_ops) is deprecated and will be removed in a future version.
Instructions for updating:
Use tf.cast instead.

Then we can train $\widehat{g}$, with minibatches of size $100$, over $5$ epochs.
In [ ]:
g_hat.fit(x, y, batch_size=100, epochs=5)

WARNING:tensorflow:From /Users/blanka/anaconda3/lib/python3.7/site-packages/tensorflow/python/ops/math_ops.py:3066: to_int32 (from tensorflow.python.ops.math_ops) is deprecated and will be removed in a future version.

Epoch 1/5

Once training has finished, we compare $g$ with the trained $\widehat{g}$.
In [8]:
x_grid = np.linspace(0,1,num=1001)
y_hat = g_hat.predict(x_grid)
g_grid = g(x_grid)
plt.plot(x_grid, y_hat, label=r”$\widehat{g}(x)$”)
plt.plot(x_grid, g_grid, “b–“, label=”$g(x)$”)
plt.xlabel(“$x$”)
plt.ylabel(“Value”)
plt.legend()
plt.show()



The function $g$ is not so hard to learn when we have $N=1\,000\,000$ samples!

To demonstrate the potential problem of overfitting, we make now the problem harder: we are going to use only the first $200$ samples. In fact, we are going to even split these $200$ samples into a training set of $100$ samples and validation set of $100$ samples.
In [0]:
N_small = 200
x_sub = x[0:N_small]
y_sub = y[0:N_small]

We now specify a blatantly overparameterised network \begin{equation} \widehat{g}_{\mathrm{over}} \in \mathcal{N}_4(1,1000,1000,1000,1;\mathrm{ReLU},\mathrm{ReLU},\mathrm{ReLU},\mathrm{Id}). \end{equation}
In [10]:
g_hat_over = keras.Sequential([
keras.layers.Dense(1000, activation=”relu”, input_shape=(1,)),
keras.layers.Dense(1000, activation=”relu”),
keras.layers.Dense(1000, activation=”relu”),
keras.layers.Dense(1, activation=”linear”)
]
)
g_hat_over.summary()

We train it with Adam using full batches over $500$ epochs.

We note that training loss becomes lower than validation loss, in fact lower than the model error variance 0.1. This is a clear sign of overfitting. Visual assessment confirms that this is indeed true.
In [12]:
y_hat = g_hat_over.predict(x_grid)
plt.plot(x_grid, y_hat, label=r”$\widehat{g}_{\mathrm{over}}(x)$”)
plt.plot(x_grid, g_grid, “b–“, label=”$g(x)$”)

We can mitigate overfitting by a regularisation technique called dropout. In a dropout layer, inputs are randomly replaced by zeros with fixed probability during training. We introduce now a dropout layer with dropout probability $0.5$ after each hidden layer:
In [13]:
g_hat_dropout = keras.Sequential([
keras.layers.Dense(1000, activation=”relu”, input_shape=(1,)),
keras.layers.Dropout(0.5),
keras.layers.Dense(1000, activation=”relu”),
keras.layers.Dropout(0.5),
keras.layers.Dense(1000, activation=”relu”),
keras.layers.Dropout(0.5),
keras.layers.Dense(1, activation=”linear”)
]

We do not see a major discrepancy between training and validation losses. Also training loss tends to stay above the model error variance $0.1$. Let us visually study the fit.
In [15]:
y_hat = g_hat_dropout.predict(x_grid)
plt.plot(x_grid, y_hat, label=r”$\widehat{g}_{\mathrm{dropout}}(x)$”)
plt.plot(x_grid, g_grid, “b–“, label=”$g(x)$”)
plt.plot(x_sub, y_sub, “go”, markersize=3, label=”$(x^i,y^i)$”)
plt.xlabel(“$x$”)
plt.ylabel(“Value”)
plt.title(“With dropout”, loc=’center’, fontsize=13)
plt.legend()
plt.show()



While the fit is not perfect (due to the small amount of samples), the overfit problem has disappeared.
