Guide to Calculating GPU Memory Requirements for LoRA and QLoRA Fine-Tuning: Understandable for Beginners

I have recently compiled a simple and easy-to-understand guide on the GPU memory requirements for fine-tuning with LoRA and QLoRA, which can help you estimate the memory needed when fine-tuning using LoRA and QLoRA. Below, we will explain step by step, requiring minimal background knowledge.1. What are LoRA and QLoRA? LoRA (Low-Rank Adaptation):This is a … Read more

Essential Tips for LoRA Fine-Tuning

by
Essential Tips for LoRA Fine-Tuning

As mentioned in previous articles, LoRA fine-tuning primarily targets the weight matrices of linear layers, such as the Q, K, and V projection matrices in the attention mechanism, as well as the weight matrices in the feedforward network (FFN). So, when fine-tuning a model with a Transformer architecture using LoRA, which weight matrices should we … Read more

Four Years Ago, the Bluetooth Alliance Excluded Huawei; Four Years Later, Huawei Integrates Bluetooth and Wi-Fi!

The Bluetooth technology was born in 1994, invented by Ericsson, with the initial goal of enabling wireless audio transmission for wireless headsets. Now, Bluetooth applications are no longer limited to wireless headsets; keyboards and game controllers also have Bluetooth versions. However, the audio quality and stability of early Bluetooth were far from satisfactory. For instance, … Read more

Sensors + AI Models = The Brain of Autonomous Driving? Analyzing How Smart Cars' 'Five Senses' Surpass Humans

 If we compare a smart car to a “living organism,” then its sensors are its eyes, ears, and skin, responsible for perceiving the world, while the AI model acts as the brain, processing information and making decisions. The key to autonomous driving lies in the perfect combination of these two—perceiving the world, understanding the … Read more
