Recall rate and accuracy rate

between 0 and 1, the closer the value is to 1, the higher the precision or recall.3. F value = correct rate * Recall rate * 2/(correct rate + recall rate) (f value is the harmonic mean of correct rate and recall rate)Example: There are 1400 carp, 300 shrimp and 300 turtles in a pond. Now for the purpose of catching carp. Sprinkle a big net, caught 700 carp, 200 shrimp, 100 turtle. So, these indicators are as follows:Correct rate = 700/(700 + 200 + 10

Dataset + Fine-tuning on low Resolution Dataset this way. In fact, this is quite reasonable, compared to learning from Scratch random initialization weights, pre-trained weights at least give a suitable weight initialization. Anyway, at the end of the Target Dataset. Note, however, that when fine-tuning, the Target dataset is up-scaling the same size as the pre-trained dataset. This should be done to ensure that the object size is consistent between pre-trained datasets and target data

The Shape object is related to the VML coordinate system _VML

Shape is the most basic object of VML, using it to draw all the graphics you want. In VML, the use of coordinates is not the document's coordinates, it has its own coordinate system, so, dynamically changing its coordinates, you can zoom in, shrink, rotate and other functions. The Coordsize property of shape is used to define coordinates, it has two parameters, coordorig= " -1400,-1400" coordsize= "2800,28

and 1, the closer the value is to 1, the higher the precision or recall. 3. F = correct rate * Recall rate * 2/(correct rate + recall rate) (f value is the correct rate and recall rate of the harmonic mean) Take this example: there are 1400 carp, 300 shrimp and 300 turtles in a pond. It is now for the purpose of catching carp. 700 Carp, 200 shrimp and 100 turtles were caught in a large net. Then, the indicators are as follows: Correct rate = 700/(

The BOC security control can cause the Windows 8 notebook keyboard to fail

As Windows 8 is still in the pre-release version, major software vendors and online service providers are gearing up for development and testing to prepare for Windows 8 compliant programs. At that time, I wrote a piece about the construction Bank Network Silver Shield is unable to use the problem and its solution. With the official listing of Windows 8, the compatibility of WIN8 with Web sites and software is commendable, thanks to the collaboration and efforts of various software providers. Fo

Shape object and VML Coordinate System

Shape is the most basic object of VML. It can be used to draw all the images you want. In VML, the coordinates used are not the coordinates of the Document. It has its own coordinate system. In this way, the coordinates of the Document can be dynamically changed to zoom in, zoom out, rotate, and other functions. The CoordSize attribute of a shape is used to define coordinates. It has two parameters: Note:The Defined coordinates are relative. The actual displayed image size also needs to be def

Linux uses Jrtplib to send and receive H.264 video files __linux

Prior to the introduction of their own direct use of RTP to send and receive H.264 data, so that there is a problem is the RTP protocol parameters need to be a bit of their own to fill, so it is not conducive to send or convenient to receive. The Jrtplib library just solves this problem, and it also provides a lot of RTCP information query interface, so it is convenient to realize real-time flow control. In this article, we will introduce h264 through the Jrtplib library to achieve real-time del
