How can Tensorflow be used to build a one dimensional convolutional network using Python?
Tensorflow is a machine learning framework that is provided by Google. It is an open-source framework used in conjunction with Python to implement algorithms, deep learning applications, and much more. It is used in research and for production purposes.
It has optimization techniques that help in performing complicated mathematical operations quickly.
This is because it uses NumPy and multi-dimensional arrays. These multi-dimensional arrays are also known as ‘tensors’. The framework supports working with deep neural networks. It is highly scalable and comes with many popular datasets. It uses GPU computation and automates the management of resources. It comes with multitude of machine learning libraries, and is well-supported and documented. The framework has the ability to run deep neural network models, train them, and create applications that predict relevant characteristics of the respective datasets.
The ‘tensorflow’ package can be installed on Windows using the below line of code −
pip install tensorflow
Tensor is a data structure used in TensorFlow. It helps connect edges in a flow diagram. This flow diagram is known as the ‘Data flow graph’. Tensors are nothing but a multidimensional array or a list.
We are using Google Colaboratory to run the below code. Google Colab or Colaboratory helps run Python code over the browser and requires zero configuration and free access to GPUs (Graphical Processing Units). Colaboratory has been built on top of Jupyter Notebook.
Example
Following is the code snippet −
print("Defining the function to build a one dimensional convolutional network")
def create_model(vocab_size, num_labels):
model = tf.keras.Sequential([
layers.Embedding(vocab_size, 64, mask_zero=True),
layers.Conv1D(64, 5, padding="valid", activation="relu", strides=2),
layers.GlobalMaxPooling1D(),
layers.Dense(num_labels)
])
return modelCode credit − https://www.tensorflow.org/tutorials/load_data/text
Output
Defining the function to build a one dimensional convolutional network
Explanation
The ‘init’ vectorized model is used to build the one dimensional convolutional neural network.
This is also done using the ‘Sequential’ API.
