model = Sequential()

model.add(Dense(150,input_dim = 44,activation="relu"))

#The input_dim =44, since the width of the training data=44 (refer data engg section)

model.add(Dense(1,activation = "linear"))

#Configure the model

model.compile(optimizer='adam',loss="mean_absolute_error",

metrics=["mean_absolute_error"])

#Train the model

model.fit(x_train.values,y_train.values, validation_data=(x_val,y_val),epochs=10,batch_size=64)

Output Train on 732390 samples, validate on 81377 samples
