Autoencoders are a highly effective category of neural networks utilized for unsupervised learning and reducing the dimensionality of data. They possess the ability to learn compact representations of input data by encoding it into a latent space of lower dimensions and subsequently decoding it to restore the original input. This article delves into the workings of autoencoders in Python, specifically employing the Keras library, to provide a comprehensive understanding of their functionality. What are autoencoders? Autoencoders are a specialized form of neural networks designed to reconstruct input data. They consist of two main parts: a decoder network, responsible for recreating ... Read More
In Python, variables are stored differently based on their type and scope either it can be stored in the heap or in the stack which are the two main memory regions utilized for a variable storage. Python, being a high-level programming language, abstracts away many low-level memory management details from the programmer. However, it's still essential to understand how variables are stored in Python to write efficient and optimized code. In this article we will see How are variables stored in Python (Stack or Heap). Stack The stack is a region of memory used for storing local variables and ... Read More
