This is a simple implementation of SOMs in Python. This SOM has periodic boundary conditions and therefore can be imagined as a "donut". The implementation usesnumpy,scipy,scikit-learnandmatplotlib. Installation som-pbccan be installed from pypi using pip: ...
In the above image the unknown cells of the map grid are not shown. To make this work, you might have to tweak the setting for the uint8 value that represents unknown cells in a ROS map image. ROS' standard map_saver uses 205, other...
One such format (incidentally, the one Lisp uses) is called an s-expression. S-expressions accomplish the same goals as XML. They're just a lot less verbose, which makes them much better suited for typing code. I will explain s-expressions in a little while, but before I do I have ...
计算各个类别的AP值后,取平均值就可以得到最终的mAP值了。但是对于COCO数据集相对比较复杂,不过其提供了计算的API,感兴趣可以看一下https://github.com/cocodataset/cocoapi/blob/master/PythonAPI/pycocotools/cocoeval.py。 注:译文相比原文略有删改。

In object-oriented computer programming, a null object is an object with no referenced value or with defined neutral ("null") behavior. The null object design pattern describes the uses of such objects and their behavior (or lack thereof). ...
