Q1: What is PyTorch?

Answer: PyTorch is a machine learning library for the programming language Python, based on Torch library, used for application such as natural language processing. It is free and open source software release under one of the BSD licenses. It has been released in October 2016 written in Python, C++, and CUDA.

Q2: Who is the founder of PyTorch?

Answer: Soumith Chintala and Hugh parkins (AI researcher in Facebook) are the founders of PyTorch.

Q3: What are the significant features of PyTorch?

Answer: The features of PyTorch are as follows:

  1. Easy interface: PyTorch offers easy to use API, and it is straightforward to operate and run on Python. The code execution is smooth.
  2. Python usage: This library is considered to be Pythonic, which smoothly integrates the Python data science stack.
  3. Computational Graphs: PyTorch provides an excellent platform which offers dynamic computational graphs. So that a user can change them during runtime, this is more useful when a developer has no idea of how much memory is required for creating a neural network model.
  4. Imperative Programming: PyTorch performs computations through each line of the written code. This is similar to Python program execution.

Q4: What are the three levels of abstraction? Answer: Levels of abstraction are as follows:

  • Tensor- Imperative n-dimensional Array which runs on GPU.
  • Variable- Node in the computational graph. This stores data and gradient.
  • Module- Neural network layer will store state otherwise learnable weights.

Q5: What are the advantages of PyTorch? Answer: The following are the advantages of PyTorch:

  • It is easy to debug.
  • It includes many layers as Torch.
  • It can be considered as NumPy extension to GPU (Graphical Processing Units).
  • It allows building network whose structure is dependent on computation itself.
  • It includes a lot of loss functions.

Q6: What are the difference between Tensorflow and PyTorch? Answer:

                              PyTorch                           TensorFlow
Pytorch is closely related to the Lua-based Torch framework, which is used on Facebook. TensorFlow is developed by Google and actively used at Google.
Pytorch is new compared to other competitive Technologies. TensorFlow is not new and is a to-go tool by many researchers and industry professionals.
Pytorch includes everything imperatively and dynamically. TensorFlow has static and dynamic graphs as a combination.
PyTorch includes Computation graph during runtime. TensorFlow does not have any runtime option.
PyTorch includes deployment highlight for mobile and embedded frameworks. TensorFlow works better for embedded frameworks.

Q7: What is Artificial Intelligence? Answer: Artificial intelligence is an excellent area of computer science that highlighted the creation of intelligent machines that work and reacts like humans. It can perform the task typically requiring human knowledge, such as visual perception, speech recognition, decision-making, etc.

Q8: What is Machine learning? Answer: Machine learning is an application of artificial intelligence (AI) that provides that systems automatically learn and improve from experience without being programmed. Machine learning points on the development of computer programs that can access data and use its trend for themselves.
