What is Keras?

02/21/2023 | by Patrick Fischer, M.Sc., Founder & Data Scientist: FDS

Keras is an open source deep learning library originally developed by François Chollet and now supported by Google. Keras provides a user-friendly API for building, training, and evaluating deep learning models.

Keras was designed to be easy to use and to enable rapid prototyping of deep learning models. It supports a variety of deep learning models, including Convolutional Neural Networks (CNNs), Recurrent Neural Networks (RNNs), and multilayer perceptrons (MLPs). Keras can also integrate with other deep learning frameworks such as TensorFlow, Theano, and CNTK.

Keras offers a variety of features that simplify deep-learning model development, including automatic differentiation, a wide range of optimizers, integrated model validation and optimization, and the ability to train models on multiple GPUs.

Keras is popular with developers because it is easy to use and produces results quickly. It is widely used in academic research projects and in industry, and is an important component of many Deep Learning applications.

What is TensorFlow?

02/21/2023 | by Patrick Fischer, M.Sc., Founder & Data Scientist: FDS

TensorFlow is an open source software library developed by Google and used to build and compute deep learning models. It provides a comprehensive set of tools, libraries, and resources that enable developers and researchers to efficiently design, train, and evaluate deep learning models.

TensorFlow is based on a graph-based computational model, where computations are represented as graphs in which the nodes are operations and the edges are data. This architecture enables efficient execution of deep learning models on GPUs and other accelerators. TensorFlow also supports computation on distributed systems to optimize model performance.

TensorFlow is written in Python and C++ and provides a variety of APIs for these languages as well as other languages such as Java and Go. It also integrates seamlessly with other tools and libraries such as NumPy, Pandas, and Matplotlib to facilitate data processing and visualization.

TensorFlow is widely used in areas such as computer vision, speech recognition, natural language processing, and many other areas of machine learning. It is one of the most widely used deep learning platforms and is used by a broad community of developers and researchers.

What is PyTorch?

02/21/2023 | by Patrick Fischer, M.Sc., Founder & Data Scientist: FDS

PyTorch is an open source machine learning framework developed by Facebook. It was originally developed as Torch in Lua and later ported to Python to reach a broader developer community. PyTorch provides an easy-to-use interface that allows developers to quickly and easily create, train, and test neural networks.

PyTorch uses a dynamic computational graph model that allows users to control the execution of the graph at runtime. This allows for greater flexibility in model creation and facilitates debugging and troubleshooting. PyTorch also provides a variety of tools and libraries to facilitate the development of deep learning models.

Another advantage of PyTorch is its integration with Python and other libraries such as NumPy and Matplotlib. This makes it easy to process and visualize data to optimize model performance. PyTorch also supports the use of GPUs and other accelerators to reduce the training time of models and achieve higher performance.

PyTorch is a widely used machine learning platform and is used by a broad community of developers and researchers. It is widely used for building deep learning models in areas such as computer vision, speech recognition, and natural language processing.
