Optimizing Large Language Models through Weight Quantization

Large Language Models (LLMs) demand significant computational resources, primarily defined by the product of parameter count and numerical precision. To minimize memory overheadd, developers use quantization—a technique that maps high-precision weights to lower-precision formats. Taxonomy of Quantization Post-Training Quantization (PTQ): Conve ...

Working with Tensors in PyTorch: Creation, Operations, and Manipulation

Tensors — the core data structure in deep learning — generalize vectors and matrices to higher diemnsions. Frameworks like PyTorch, TensorFlow, and MXNet provide tensor types (Tensor in PyTorch/TensorFlow, ndarray in MXNet) that closely resemble NumPy's ndarray, but extend it with critical capabilities such as GPU acceleration and automatic dif ...
