machine-learning - grid.py 运行需要多长时间？

Question

我正在使用 libsvm 进行二进制分类..我想尝试 grid.py ，因为据说它可以改善结果..我在不同的终端中为五个文件运行了这个脚本，并且该脚本已经运行了超过 12小时..

这是我的 5 个终端现在的状态:

[root@localhost tools]# python grid.py sarts_nonarts_feat.txt>grid_arts.txt
Warning: empty z range [61.3997:61.3997], adjusting to [60.7857:62.0137]

[root@localhost tools]# python grid.py snews_nonnews_feat.txt>grid_news.txt
Wrong input format at line 494
Traceback (most recent call last):
  File "grid.py", line 223, in run
    if rate is None: raise "get no rate"
TypeError: exceptions must be classes or instances, not str

我已将输出重定向到文件，但这些文件目前不包含任何内容.. 并且，创建了以下文件:

• sbiz_nonbiz_feat.txt.out
• sbiz_nonbiz_feat.txt.png
• sarts_nonarts_feat.txt.out
• sarts_nonarts_feat.txt.png
• sgames_nongames_feat.txt.out
• sgames_nongames_feat.txt.png
• sref_nonref_feat.txt.out
• sref_nonref_feat.txt.png
• snews_nonnews_feat.txt.out(--> 为空)

.out 文件中只有一行信息..
“.png”文件是一些 GNU PLOTS。

但是我不明白上面的 GNUplots/警告传达了什么..我应该重新运行它们吗？

谁能告诉我，如果每个输入文件包含大约 144000 行，这个脚本可能需要多少时间..

感谢和问候

您的数据非常庞大，有 144 000 行。所以这需要一些时间。我使用了像你这样的大数据，花了一周的时间才完成。如果您使用图像(我想您就是这样)，因此数据很大，请尝试在创建数据之前调整图像大小。调整图像大小后，您应该会得到大致相同的结果。
