TensorFlow is an open-source machine learning framework developed by Google. It provides a flexible and powerful platform to build and deploy machine learning (ML) and deep learning (DL) models across different environments — desktops, servers, browsers, and mobile devices

Example Code (Simple Linear Model)

import tensorflow as tf

from tensorflow import keras

import numpy as np

# Training data

x = np.array([1.0, 2.0, 3.0, 4.0])

y = np.array([2.0, 4.0, 6.0, 8.0])

# Build a simple linear model

model = keras.Sequential([keras.layers.Dense(units=1, input_shape=[1])])

# Compile the model

model.compile(optimizer=’sgd’, loss=’mean_squared_error’)

# Train the model

model.fit(x, y, epochs=500, verbose=0)

# Predict

print(model.predict([10.0]))  # Should output ~20
