tensorflow中更快的rcnn配置文件

我正在使用tensorflow中的Google对自定义数据集进行训练和推断

我想调整配置文件的参数，以更好地适应我的样本（例如，区域提案的数量、ROI bbox的大小等）。 为此，我需要知道每个参数的作用。 遗憾的是，配置文件（找到的）没有注释或解释。 有些，如“num类”是不言自明的，但有些则很棘手

我发现有更多的评论，但无法将其“翻译”为我的格式

我想知道以下情况之一： 1.谷歌API配置文件的每个参数说明 或 2. '从官方更快的rcnn到谷歌API配置的翻译 或者至少 3.通过参数的技术细节对更快的rcnn进行全面审查（官方文章没有提供所有细节）

谢谢你的帮助

配置文件的示例：

# Faster R-CNN with Resnet-101 (v1) configuration for MSCOCO Dataset.
# Users should configure the fine_tune_checkpoint field in the train config as
# well as the label_map_path and input_path fields in the train_input_reader and
# eval_input_reader. Search for "PATH_TO_BE_CONFIGURED" to find the fields that
# should be configured.

我发现了两个关于配置文件的来源： 1.tensorflow github中的文件夹涵盖了所有配置选项，并对每个选项进行了一些注释。对于最常见的问题，您应该更快地签出\u rcnn.proto、eval.proto和train.proto 2.Algorithmia的博客文章全面涵盖了在谷歌的开放图像数据集上下载、准备和训练更快的RCNN的所有步骤。通过2/3，对配置选项进行了一些讨论
