Keras vs Tensorflow

Machine Learning and Deep Learning have experienced unusual tours from bust to boom from the last decade. Simmering in research labs, these two verticals of artificial intelligence became a savior for many companies. As there is a famous saying, “the larger, the better.” But when it comes to large data sets, determining insights from them through deep learning algorithms and mining them becomes tricky. The two most popular deep learning frameworks that machine learning and deep learning engineers prefer are TensorFlow and Keras. Since the initial release of Keras and TensorFlow in the year 2015, both became the most widely-known Deep learning frameworks. Both these frameworks are easy to use and have simpler APIs than their predecessors. Both Keras and TensorFlow help developers increase the functionality across data and more control over training machine learning models. .The bar graph shows the growth of both Keras and TensorFlow 3 years after its initial release.

Deep Learning algorithms can imitate the working of the human brain. It creates patterns and feeds on data to make machines eligible to reap decisions on their own. Deep learning renders various types of AI functions that mimic the brain functionality, called artificial neural networks. Deep learning techniques leverage machine learning models with artificial intelligence to create neural nets. These networks can perform unsupervised learning from unstructured, semi-structured, and unlabelled data. As deep learning algorithms and models create deep networks mimicking the brain, it has an alternative name, deep neural learning.

Nowadays, Deep Learning is almost everywhere. From virtual assistants in your smartphones and smart home devices to visual recognition, fraud detectors, self-driving cars, healthcare equipment, everything utilizes Deep Learning algorithms and methods. 2016 was the year when Deep Learning showed some significant advancement, and since then, it has all been set on fuel and fire. By the end of 2022, Gartner predicts that more than 75% of enterprises and firms will start implementing DNNs cultivating classical machine learning techniques. There are a lot of deep learning frameworks available. Therefore, it becomes difficult for beginners to choose between the two. In this article, we will highlight some of the important differences between Keras and Tensorflow to help you make the right choice for your use case.

Keras vs Tensorflow – A Quick Overview

What is TensorFlow?

It is the most popular Deep Learning library that helps engineers, Deep neural scientists, and others to create deep learning algorithms and models. Google Brain team is the brainchild behind this open-source library that leverages dataflow programmers to deal with numerical computation & large-scale supervised and unsupervised learning. TensorFlow clusters together machine learning and deep learning models and renders them through large datasets to train these models to think and create sensible outcomes on their own. Developers and engineers use Python to implement this library, plus creating a suitable front-end for using the framework.

The design and purpose of TensorFlow are mainly to run deep neural networks and train machines to learn and make prompt decisions. Companies also use TensorFlow for image recognition, hand-written character classification, recurrent neural networks, word embeddings, NLP for teaching machines to understand human languages, sequence-to-sequence models for machine translation, and PDE (partial differential equation) simulations. TensorFlow also helps in sales analysis and predict production units required at scale. Medical science and healthcare devices using AI also leverage TensorFlow to determine accurate solutions.

What is Keras?

Deep neural learning has been in a rage since 2017. With its growth, the complexity of all the dominant frameworks became a barrier for data science and machine learning engineers. Developers and engineers put forward many proposals for a simplified yet high-level API for building large neural networks and models. After going through a long research and adaptation phase, Keras became the choice of high-level neural network. Keras is an open-source deep neural network library developed by François Chollet, who is a Google engineer. He designed it to be fast, easy to implement, and modular by nature. François created Keras using Python that runs on top of Theano. Since then, Keras got adopted as the high-level API for developing deep learning algorithms. It also helps in the rapid prototyping of deep neural models.
