python-tensorflowHow can I use Python and TensorFlow to create a stock prediction model?

Using Python and TensorFlow to create a stock prediction model is a popular machine learning task. The following is an example of how to do this:

#import TensorFlow and other libraries
import tensorflow as tf
import numpy as np

#define the model
model = tf.keras.Sequential([
    tf.keras.layers.Dense(units=1, input_shape=[1])
])

#compile the model
model.compile(optimizer='sgd', loss='mean_squared_error')

#provide the data
xs = np.array([1,2,3,4,5,6,7,8,9,10], dtype=float)
ys = np.array([1.5,3,4.5,6,7.5,9,10.5,12,13.5,15], dtype=float)

#train the model
model.fit(xs, ys, epochs=500)

#make a prediction
print(model.predict([11.0]))

Output example

[[16.492437]]

Code explanation

1. Import TensorFlow and other libraries: import tensorflow as tf and import numpy as np
2. Define the model: model = tf.keras.Sequential([tf.keras.layers.Dense(units=1, input_shape=[1])])
3. Compile the model: model.compile(optimizer='sgd', loss='mean_squared_error')
4. Provide the data: xs = np.array([1,2,3,4,5,6,7,8,9,10], dtype=float) and ys = np.array([1.5,3,4.5,6,7.5,9,10.5,12,13.5,15], dtype=float)
5. Train the model: model.fit(xs, ys, epochs=500)
6. Make a prediction: print(model.predict([11.0]))
