We already have seen how to design a simple Perceptron to perform a regression. Also, we observed that the normalization of the data and target should match the structure of our model. However, just guaranteeing the data is in the correct range is not enough. Let’s see how it works.
[2]:
# #What are we trying to beat
# data = pd.read_csv('./tree_height/txt/eu_x_y_height_predictors.txt', sep=" ")
# # data = pd.read_csv('./tree_height/txt/eu_x_y_height.txt', sep=" ")
# print(data.shape)
# print(data.head())
# y_true = data['h']
# y_pred = data['forest_height']
# slope, intercept, r_value, p_value, std_err = scipy.stats.linregress(y_pred, y_true)
# fig,ax=plt.subplots(1,1,figsize=(5,5))
# ax.scatter(y_pred, y_true)
# ax.set_xlabel('Prediction')
# ax.set_ylabel('True')
# ax.set_title('slope: {:.4f}, r_value: {:.4f}'.format(slope, r_value))
# plt.show()
Let’s start by loading the data we used in the previous class

### Try the the tree height with Perceptron
# data = pd.read_csv('./tree_height/txt/eu_x_y_height_predictors.txt', sep=" ")
data = pd.read_csv('./tree_height/txt/eu_x_y_height.txt', sep=" ")
print(data.shape)

Finally, let’s create and initialize our Perceptron
[33]:
# Create the model

def __init__(self,input_size, output_size,use_activation_fn=None):
super(Perceptron, self).__init__()
self.fc = nn.Linear(input_size,output_size)
self.relu = torch.nn.ReLU() # instead of Heaviside step fn
self.sigmoid = torch.nn.Sigmoid()
self.tanh = torch.nn.Tanh()
self.use_activation_fn=use_activation_fn
def forward(self, x):
output = self.fc(x)
if self.use_activation_fn=='sigmoid':
output = self.sigmoid(output) # To add the non-linearity. Try training you Perceptron with and without the non-linearity
elif self.use_activation_fn=='tanh':
output = self.tanh(output)
elif self.use_activation_fn=='relu':
output = self.relu(output)
return output
[26]:
#Just in case, remember to always delete previously existent models before starting a new session

Let’s train and check our model’s performance

y_pred = model(X_train)

Well, they all performed badly. What can we do to make this model better? One thing that immediatly jumps to our eyes is the fact that this data is very skewed. There are many ways to normalized sweked data. Check out this great post about normalization and popular power transformations power transformations. Here I will introduce another one: the Quantile Transformation. Also, if you would like to see a great comparison between transformations, check out this skelarn post
For now, let’s use the power transformation just for our target variable (ie, tree height).
[28]:
from sklearn.preprocessing import QuantileTransformer
qt = QuantileTransformer(
n_quantiles=500, output_distribution="normal", random_state=0
)
# X_train, X_test = train_test_split(data, test_size=0.5)
# data = qt.fit_transform(data)
data[:,2] = qt.fit_transform(data[:,2].reshape(-1,1)).squeeze()

#Normalize the data
from sklearn.preprocessing import MinMaxScaler
scaler = MinMaxScaler()
data = scaler.fit_transform(data)
data[:,2] = ((data[:,2]-data[:,2].min())/(data[:,2].max()-data[:,2].min()))*2-1
# data[:,2] = data[:,2]/np.quantile(np.abs(data[:,2]),0.99)
data[:,2] = data[:,2]/data[:,2].max()
