We compare models trained by Self-Filtering (with mix of $30\%$ or $40\%$ selected samples) to models trained on either all data, or trained on data selected by OpenAI's CLIP. The proposed Self-Filtering approach leads to improved results. We show the average and $\pm 1$ standard deviation of 3 seeds.这张图/表用于判断 Data Selection Through Iterative Self-Filtering 的实验收益来自哪里。重点看替换、消融或跨模型设置下趋势是否一致,而不是只看单个最高分。

In the second and third panel the models are initialized from the same checkpoint from steps corresponding to 12.8 M and $4 \times 12.8$ M examples seen, respectively. For a small number of training steps, using exclusively filtered data is best, but overall, the mixing strategy achieves the best results. Unlike before, we use a constant learning rate here.这张图/表用于判断 Data Selection Through Iterative Self-Filtering 的实验收益来自哪里。重点看替换、消融或跨模型设置下趋势是否一致,而不是只看单个最高分。

实验看点

实验部分建议重点看两类证据:一是作者是否把方法收益和更强数据、更长训练、更大模型区分开;二是跨模型、跨数据或跨任务迁移是否还能保留同样趋势。

局限与读法

这篇论文的结论需要结合任务设置、训练数据规模和消融实验一起看;不要只凭单个指标判断它对通用视觉表征的价值。
