Bandpass filter for 915 MHz center frequency suitable for LoRa, LoRaWAN, GSM / 3G with SMA-male and SMA-female connectors. Enhances receiver sensitivity, mitigates interference, and aids in frequency planning.
A look at this year’s crop of LoRA alternatives, including SVF, SVFT, MiLoRA, PiSSA, and LoRA-XS, all based on SVD (Singular Value Decomposition). The article compares these techniques to the original LoRA method for fine-tuning Large Language Models.
| Method | Description | Key Feature(s) | Reference |
|--------------|---------------------------------------------|---------------------------------------------|-|
| LoRA | Freezes the model and trains a small pair of low-rank “adapter” matrices. | Saves memory and compute cycles by reducing the number of trainable parameters. | arxiv.org/abs/2106.09685 |
| SVF | Uses SVD on the model’s weight matrices and fine-tunes the singular values directly. | More economical in parameters than LoRA; makes tuned models composable. | arxiv.org/abs/2501.06252v2 |
| SVFT | Adds more trainable weights on the diagonal and evaluates various alternatives. | Provides more trainable values than just the diagonal, useful for better fine-tuning. | arxiv.org/abs/2405.19597 |
| PiSSA | Tunes only the large principal values. | Designed to approximate full fine-tuning by adapting the principal singular components. | arxiv.org/abs/2404.02948 |
| MiLoRA | Tunes only the small principal values. | Retains base model’s knowledge while adapting to new tasks. | arxiv.org/abs/2406.09044 |
| LoRA-XS | Similar to PiSSA but with a slightly different mechanism. | Shows good results with significantly fewer parameters than LoRA. | arxiv.org/abs/2405.17604 |
| DoRA | Splits weights into magnitudes and directions then tunes those. | | arxiv.org/abs/2402.09353 |
| AdaLoRA | Complex mechanism for finding the best tuning rank for a given budget of trainable weights. | | arxiv.org/abs/2303.10512 |

Sergey Pletenev et al. explore the integration of new knowledge into Large Language Models (LLMs) using Low-Rank Adaptation (LoRA). The study focuses on fine-tuning the Llama-3.1-8B-instruct model with varying amounts of new information while aiming to retain previously learned knowledge. The researchers found that mixing known and new facts in training data yields the best results but also noted potential drawbacks, such as a decline in performance on external benchmarks and a bias towards overrepresented answers when the data is skewed. Additionally, the model sometimes becomes overly confident and hesitant to answer. These findings emphasize the need for careful consideration of training data composition and tuning parameters to balance the incorporation of new knowledge with maintaining overall model capabilities.
