Keras vs. TensorFlow: Key Differences


Machine learning and deep learning have been through a revolutionary transition in the last decade. Most of the work around these two technologies had been limited to research labs. However, it is important to note that the two most prominent disciplines of artificial intelligence have emerged as lifesavers for many businesses. The Keras vs. TensorFlow debate has been gaining attention as they are the most popular deep learning frameworks that can help machine learning and deep learning engineers. It is important to note that machine learning and deep learning engineers have to work on larger data sets that continue expanding.

TensorFlow and Keras can help developers achieve more functionality with data alongside exercising better control on training ML models. Let us explore the differences between TensorFlow and Keras to determine the best pick among them.

Overview of Keras 

Keras is an open-source, high-level neural network library created by Google engineer Francois Chollet. The primary objective of creating Keras was focused on improving the accessibility of deep learning. The Keras and TensorFlow difference is visible in the fact that you don’t need coding expertise to develop neural networks with Keras.

It offers a high-level API that can help in abstraction of complexities associated with deep learning. On top of that, Keras also offers pre-build layers, optimizers, and activation functions that help you focus on designing the model rather than worrying about technicalities. Keras has been developed with Python programming language, thereby helping Python programmers learn its functionalities with ease. 

Before you compare Keras and TensorFlow, you must know that Keras stands out for its simplicity and adaptability. It helps you explore model designs and enables faster prototyping with the features for examining performance of different designs as you adjust hyperparameters. Keras has been instrumental in fuelling advancements in natural language processing, speech recognition, and computer vision.

Overview of TensorFlow

TensorFlow is another powerhouse in the domain of deep learning and AI. It is the most renowned deep learning framework, primarily because it was created by Google Brain team. Questions like “Is Keras the same as TensorFlow?” emerge from the fact that both of them are open-source libraries.

In the case of TensorFlow, the library is tailored for numerical computation tasks that leverage data flow graphs. TensorFlow helps in conducting computations on GPUs, CPUs, and distributed systems by using nodes to represent mathematical operations. The edges in TensorFlow represent data flow channels. 

TensorFlow helps in creating different ML and deep learning models. It helps deep learning researchers create different types of supervised and unsupervised learning algorithms. Developers can use TensorFlow with different programming languages such as C++, Java, and Python. The primary objective of TensorFlow revolves around training ML models on large datasets to help them make faster decisions. TensorFlow has emerged as a trusted tool for use in cases such as image recognition, natural language processing, recurrent neural networks, and word embeddings.

What are the Most Notable Differences between TensorFlow and Keras?

The overview of TensorFlow and Keras shows that both of them are similar in many ways. However, the Keras and TensorFlow compatibility is significantly limited, as there are multiple differences between them. Here is an overview of some of the notable differences between TensorFlow and Keras.

The best way to compare TensorFlow with Keras would involve finding out their use cases. TensorFlow is more flexible and has robust features to manage and process large data sets. It is useful for research as well as practical applications in the domain of AI. Some of the most notable use cases of TensorFlow include image recognition, generative models, image synthesis, and predictive analytics. 

Convolutional Neural Networks use TensorFlow for better performance in image classification, facial recognition, and object detection. The capabilities of TensorFlow for prediction of numerical values by leveraging historical data can be useful for regression and predictive analytics tasks. On top of that, TensorFlow can power GANs that help create realistic videos, synthesize images, augment data, and improve visual effects. 

On the other hand, in the TensorFlow vs. Keras comparison, Keras is more useful for different machine learning tasks. It is the top choice of developers for natural language processing tasks, reinforcement learning, and transfer learning. Keras helps power NLP applications such as language translation, sentiment analysis, and text classification.

Developers can use the Keras API to implement reinforcement learning algorithms that can power autonomous systems and robotics. Another important use of Keras is transfer learning, which helps in creating pre-trained models that you can fine-tune for specific tasks.
