What Is TensorFlow?
TensorFlow, developed by Google Brain Team open-source framework for machine learning and artificial intelligenceis. The name multi-dimensional data arrays which are ‘tensor’is. These tensors, neural networks between ‘flow’ (stream) moves into.
TensorFlow, the basic data structure, which is the name ‘tensor’is. Tensors, multi-dimensional data arrays, and shall serve as the main carrier of information in neural networks. In the framework, this chart is a calculation of the Tensor (computational graph) on processes. The structure of this graph, is a visual representation of mathematical operations and data flow.
The frameworkis one of the most important features of automatic calculation of differential (automatic differentiation) is the ability of. This feature gradient calculations by automating the training of deep learning model significantly easier. Also, TensorFlow 2.by enabling eager execution X version feature codes that come with the instant execution of the debug process easier.
TensorFlowflour the modular structure of different hardware platforms (CPU, GPU, TPU) provides optimum performance. Especially Nvidia GPUcompatibility with S, deep learning model training time will be significantly reduced. The framework also thanks to the capabilities of distributed computing, large-scale cluster systems may perform on their education model.
TensorFlow with these characteristics, both in research projects, as well as for industrial applications has become the preferred framework. Especially when working on large data sets provides the scalability and performance advantages are important factors that distinguishes it from its competitors.
