概述
AIOZ-GDANCE 数据集是一个用于音乐驱动群舞生成的大型数据集,包含16.7小时的配对音乐和3D舞蹈动作,涵盖7种舞蹈风格和16种音乐类型。该数据集支持群舞研究,并提供了一种半自主的标注方法,通过人在环路中获取3D地面真实数据。

数据结构
数据集目录结构如下:
- split_sequence_names.txt: 包含数据中各个序列名称的txt文件。
- musics: 包含每个序列对应的原始音乐.wav文件,音乐帧与动作帧对齐。
- motions_smpl: 包含每个序列对应的.pkl格式动作文件,主要包含以下项目:
smpl_poses: shape[num_persons x num_frames x 72]
: 72维向量姿态序列,采用SMPL姿态格式(24个关节)。root_trans: shape[num_persons x num_frames x 3]
: 根翻译序列。
示例代码
以下是一个读取动作文件的Python示例代码: python import pickle import numpy as np data = pickle.load(open("sequence_name.pkl","rb")) print(data.keys())
smpl_poses = data[smpl_poses] smpl_trans = data[root_trans]
可视化
数据集提供了加载和可视化动作的演示代码。
前提条件
需要下载SMPL模型(v1.0.0)并重命名模型文件。数据目录结构应为:
<DATA_DIR> ├── motions_smpl/ ├── musics/ └── split_sequence_names.txt
<SMPL_DIR> ├── SMPL_MALE.pkl └── SMPL_FEMALE.pkl
安装必要的包:
pip install scipy torch smplx chumpy vedo trimesh pip install numpy==1.23.0
使用方法
可视化SMPL关节
以下命令将计算SMPL关节位置并在3D图形中实时绘制: bash python vis_smpl_kpt.py --data_dir <DATA_DIR>/motions_smpl --smpl_path <SMPL_DIR>/SMPL_FEMALE.PKL --sequence_name sequence_name.pkl
可视化SMPL网格
以下命令将计算SMPL网格并在3D中可视化: bash python vis_smpl_mesh.py --data_dir <DATA_DIR>/motions_smpl --smpl_path <SMPL_DIR>/SMPL_FEMALE.PKL --sequence_name sequence_name.pkl

Population and Housing Census of 2007 - Ethiopia
Geographic coverage --------------------------- National coverage Analysis unit --------------------------- Household Person Housing unit Universe --------------------------- The census has counted people on dejure and defacto basis. The dejure population comprises all the persons who belong to a given area at a given time by virtue of usual residence, while under defacto approach people were counted as the residents of the place where they found. In the census, a person is said to be a usual resident of a household (and hence an area) if he/she has been residing in the household continuously for at least six months before the census day or intends to reside in the household for six months or longer. Thus, visitors are not included with the usual (dejure) population. Homeless persons were enumerated in the place where they spent the night on the enumeration day. The 2007 census counted foreign nationals who were residing in the city administration. On the other hand all Ethiopians living abroad were not counted. Kind of data --------------------------- Census/enumeration data [cen] Mode of data collection --------------------------- Face-to-face [f2f] Research instrument --------------------------- Two type sof questionnaires were used to collect census data: i) Short questionnaire ii) Long questionnaire Unlike the previous censuses, the contents of the short and long questionnaires were similar both for the urban and rural areas as well as for the entire city. But the short and the long questionnaires differ by the number of variables they contained. That is, the short questionnaire was used to collect basic data on population characteristics, such as population size, sex, age, language, ethnic group, religion, orphanhood and disability. Whereas the long questionnaire includes information on marital status, education, economic activity, migration, fertility, mortality, as well as housing stocks and conditions in addition to those questions contained in a short questionnaire.

Analog Circuit Fault Diagnosis Dataset
The simulation experiment is based on Candence 16.6 software, where the tolerance of the resistance (R) is set to 5%, the tolerance of the capacitance (C) is set to 10%, the input is a single-pulse signal (amplitude 5 V, pulse width 10 µs, eriod 2ms), and the working temperature is set to 27 ℃. The operational amplifier(op-amp) uses the actual UA741 pspice model. The experiment includes the soft fault diagnosis of Sallen-Key band-pass filter circuit (TC1), Four-op-amp biquad high-pass filter circuit (TC2), and Leap-frog low-pass filter circuit (TC3). The dataset is a CSV file, with each row representing a feature vector, the last column being the data label, and the remaining columns being the feature vectors.
