Quantization is the process of mapping input values from a continuous range to a discrete set of values. Convolution is a mathematical operation that combines two functions to produce a third function.
Quantization reduces the precision of data by mapping it to a smaller set of values. For example, converting a grayscale image from 256 levels to 8 levels.
Convolution involves sliding one function over another and multipl...
Swapping two numbers without using a third variable
Use arithmetic operations to swap values
Example: a = 5, b = 10; a = a + b; b = a - b; a = a - b;
Ensure no overflow or underflow occurs

Transformer architecture is a deep learning model that uses self-attention mechanism to process sequential data.
Transformer architecture consists of an encoder and a decoder.
Self-attention mechanism allows the model to weigh the importance of different input tokens when making predictions.
Transformer models have been widely used in natural language processing tasks such as machine translation and text generation.
