Methods and codes of data amplification data-augmentation

In order to amplify the data set, 2 ways are used to amplify the data. 1. Data enhancement processing using Keras 2. Data enhancement processing using Skimage Keras includes processing, there is featurewise visual image will be slightly dimmed, samplewise visual image will become class X-ray image form, ZCA processing visual image will become gray image, rotation range randomly rotated image, horizontal translation, vertical translation, Error-cutting transformation, image scaling, picture

What is InfiniBand multi-rail? Amazing

The explanation is as follows: Multi-rail support (multiple ports per adapter and multiple adapters) It looks a bit like multi-nic binding or multi-port binding on a single InfiniBand Nic. But this is not the case. Of course, binding multiple NICs or multiple ports will increase the bandwidth, but the multi-rail here is not that simple. In fact, the term "Multi-Rail" is not limited to InfiniBand, Ethernet, and Myrinet. Multi-Rail refers to simultaneous communication by using multiple NICs or mu

The future is full of uncertainty. David Kirk, chief scientist at NVIDIA, said heterogeneous computing architecture is indeed the most effective solution for processing various types of data, however, he does not think that the knights corner accelerator developed by Intel can build a practical heterogene

Analysis of multithread network connection programming in J2ME

into the active state, which is the main thread, the program branch. It performs other methods and then returns to this branch to continue execution. However, a network connection is a potentially clogged operation, meaning it may not return for long periods of time. While simulating a segment of the network connection program running in Sun's wireless development Kit WTK, WTK prompts the network connection to work to plug user input and create another thread for networking. For the above situ

Dicom image pixel value (grayscale value) converted to CT value

The Unit of CT value is Hounsfield, referred to as Hu, the range is-1024-3071. It is used to measure the absorption rate of X-rays in human tissues, and to set the water absorption rate at 0Hu.In the dicom image reading process, we will find that the pixel value of the image may not be this range, usually 0-4096, which is the pixel value we often see or grayscale value, which requires us to the image pixel value (gray value) into the CT value.First, you need to read two dicom tag information (00

Shift and scale transformations are performed using these two parameters:The resulting data conforms to the standard distribution with a mean value of 0 and a variance of 1.(2) is the re-translational parameter (re-shift parameter), which is the rescale parameter (re-scale parameter). The further transformations you get from the previous step are:The resulting data conforms to the distribution of th

Openmosix Learning Experience: differences between openmosix and PBS Systems

Openmosix (www.openmosix.org) is an open-source project, formerly mosix, and openmosix is an open-source implementation of mosix. Generally, HPC clusters are called Beowulf clusters, while mosix clusters are completely different from HPC clusters. The openmosix cluster is a kernel patch that balances tasks at the kernel layer. For example, a cluster has 10 nodes, so if we want to suppress 10 MP3, we only ne
