其中纵轴表示最终的验证损失(Val Loss),横轴表示不同的模型规模(Model Size),从30M到220M参数。不同的颜色代表了不同的训练精度,从INT3到INT6,以及没有后训练量化(No PTQ)。研究发现,在较低精度下训练模型(例如INT3和INT4)会导致较高的损失,而随着精度的提高,损失会减少;同时,随着模型规模的增...

随着模型size的增大,模型效果不断提升; 随着模型使用的finetune数据集的增多,模型效果也是不断提升的。 CoT对模型效果的影响 由于在指令微调混合中包含思想链 (CoT) 数据,导致 Flan-PaLM 的推理能力得到改进,在多个基准测试中超越了先前的模型。 该研究消融了 CoT 微调数据,表明没有 CoT 的指令微调实际上会降低推...
3.1 “Head”解耦权重衰减 在低数据条件下,权值衰减对model adaptation有显著影响。作者对这一现象进行了mid-size规模的研究。 作者发现,对于模型中的最后一个线性层(“Head”)和其余的权重(“Body”)可以从解耦权值衰减强度中获益。 上图展示了这种效应:在JFT-300M上训练一个collection ViT-B/32模型,每个cell对应...
Scaling law不仅是一个好用的工具,它本身的存在也给出了能影响模型效果的关键因素,指导着算法的迭代方向,比如在预训练中,核心是数据量、模型尺寸,最近Deepseek[2]的工作中也对batch size、learning rate这两个重要超参数进行了分析。而在对齐阶段,综合上面两篇工作,数据量、模型尺寸、RM尺寸都对效果有着规律清晰的...

The goal of the ribbon is to maintain visibility of relevant controls even when the horizontal size of the window changes. To achieve this, the UI definition allows you to control how controls in a group change size in response to changes in the size of the window. This is known as ...
Figure 8. Throughput per GPU of pipeline parallelism using two different batch sizes in a weak-scaling experiment setup. Model size increases with the pipeline-parallel size. The number of floating point operations (numerator of throughput) is computed analytically based on the model architecture, ta...
When you want to resize geometry within your model and maintain its proportions, you can use either the Tape Measure tool or the Scale tool. Your choice depends on how you want to set the scale: To base the scale on the size of a specific line, use the Tape Measure. For example, you...
