To build a neural network, you can utilize the TensorFlow library. Here are some steps to construct a basic neural network:

  1. Import the necessary libraries.
import tensorflow as tf
from tensorflow.keras import layers
  1. Create a sequence of layers using tf.keras.
model = tf.keras.Sequential()
model.add(layers.Dense(units=64, activation='relu', input_dim=100))
model.add(layers.Dense(units=64, activation='relu'))
model.add(layers.Dense(units=10, activation='softmax'))
  1. put together
model.compile(optimizer='rmsprop',
              loss='categorical_crossentropy',
              metrics=['accuracy'])
  1. Load data:
    Load your training data and labels.
  2. Train the model: Use the fit method to train the model.
model.fit(data, labels, epochs=10, batch_size=32)
  1. assess
loss, accuracy = model.evaluate(data, labels)
  1. forecast
predictions = model.predict(data)

This is just a simple example, TensorFlow also offers many other functions and types of models to use. You can choose and build a suitable neural network structure according to your needs.
