Dataset of channels and received IEEE 802.11ay signals for sensing applications in the 60GHz band

Data provided by  National Institute of Standards and Technology

The dataset can be used to develop and test algorithms for communication and sensing in the 60GHz band. The dataset consists of synthetically generated indoor mm-wave channels between a MIMO transmitter and a MIMO receivers. Multiple targets are moving in the room. Number of targets, velocity of each target and trajectory are randomized across the dataset. The dataset contains also noisy received IEEE 802.11ay channel estimation fields. The dataset is suitable for development and testing of machine/deep learning algorithms.

Translator from Extended SysML to Physical Interaction and Signal Flow Simulation Platforms, version 1.1

Data provided by  National Institute of Standards and Technology

The translator implements the SysML Extension for Physical Interaction and Signal Flow Simulation (SysPhS), version 1.1. It can generate Modelica and Simulink/Simscape files from SysML models extended according to the SysPhS specification. This dataset binary and source code for the translator, as well as a set of SysML models that can be translated into simulation models. Disclaimer: Certain commercial equipment, instruments, or materials are identified in this dataset to specify the experimental procedure adequately.

Deep Video Understanding Annotations Dataset

Data provided by  National Institute of Standards and Technology

The BBC Land Girls TV series is a 3 season series. Each season is 5 episodes of about 45mins each. The TRECVID group at NIST worked with the BBC Corp. to release the dataset to the research community to work on video understanding tasks. Unfortunately, the hosting arrangement for the dataset was not successful and the release of the video dataset couldn't be done. We are releasing the annotations conducted by NIST, without any video data, so that the researchers interested in working on knowledge graph understanding and natural language analysis can take advantage of them.
