TensorFlow vs Keras vs PyTorch

TensorFlow Keras PyTorch
API level high / low high low
Speed very fast slower very fast
Dataset large small large
Debugging hard easy/less frequent easy
Most commonly used Image NLP / Computer Vision

API

  • API : application programming interface
    • Low : more detailed. And allows you to have more detailed control to manipulate functions
    • High: more simply , easier

Keras

  • Keras: wait for tensorflow to finish its implementation then starts its own implementation

Dataflow

  • Dataflow
    • Advantage:

      • Parallelism
        ->easy for the system to identify operations executed in parallel
      • Distributed execution
        • -> it is possible for TensorFlow to partition our program across multiple CPU/GPU as all tensors(variables) are immutable (can NOT update the content, and only new tensor will be created).
    • Process:

      1. Define the dataflow graph
      2. Create a TensorFlow session and Run
    • terms

      • node: units of computation
      • edges: data consumed/produced by a computation
      • tensor: variable e.g., x and y
      • operator: mathematical operator e.g., + and /
