As we are living in an economically fragile period with a pandemic of the New Coronavirus, an important thought emerged in the minds of many Brazilian investors, as well as common people looking for a permanent home.
Based on this assumption, this project is a method for creating a model for predicting house prices in Melbourne, Australia, using Python, TensorFlow2 and KerasTuner
With the techniques used in this work and having a good dataset in hands, you can solve almost any linear or non-linear regression problem using MLP.
This repository contains all code used in this article on Medium.
As we said before, the main key of this project is KerasTuner. The fucntion used to implement de Hyperparameter Tuning is shown below.
def model_builder(hp):
model = tf.keras.Sequential()
# Creates a model with 5 to 10 layers
for i in range(hp.Int('num_layers', 5, 10)):
# Tune the number of units in dense layers
hp_int = hp.Int('units_' + str(i), min_value = 128, max_value = 768, step = 128)
# Choose the best value between 128-768
model.add(tf.keras.layers.Dense(units=hp_int, kernel_initializer='he_uniform'))
# Add batch normalization before activation function
model.add(tf.keras.layers.BatchNormalization())
model.add(tf.keras.layers.Activation(tf.nn.relu))
# Add Dropout
model.add(tf.keras.layers.Dropout(0.2))
# Output layer
model.add(tf.keras.layers.Dense(1, activation=tf.nn.relu))
# Tune the optmizer's learning rate by choosing the best value
# between 0.01, 0.001 and 0.0001
hp_learning_rate = hp.Choice('learning_rate', values=[1e-2, 1e-3, 1e-4])
opt = tf.keras.optimizers.Adam(learning_rate=hp_learning_rate)
# Configure the optmizer, loss and supervised metrics
model.compile(optimizer=opt, loss='mape', metrics=['mae'])
return modelFirst of all, you have to have access to a Python enviroment and JupyterNotebook installed to open the main file HousePricePrediction.ipynb and run this project, or you can just forget all of that and simply create (probably you already have) a gmail account with access to Google Colab (which I prefer). Since this is basic, let's skip this part.
Assuming you have all of the above you just need to clone this repo.
git clone https://github.com/Lucastmarques/fine-tuning-house-price.git
And download all dependencies:
pip install requirements.txt
Since we use JupyterNotebook to develop the entire project, each section of the code is documented and explained in markdown. Futhermore, every snippet of code is well commented and organized to be as didactic as possible.
Feel free to raise any type of issues or feature requests in this project.
