Dr. Junjie Zhao (赵俊杰) received his Ph.D. degree in theoretical physics from Peking University in 2021 and is currently doing scientific research as a "LiYun" postdoctoral fellow (励耘博士后) in the Department of Astronomy, Beijing Normal University. The main research interests are gravitational-wave physics, testing gravity, physics of pulsar, etc.

Below is the overview of this seminar.

• Brief introduction to gravitational wave (引力波简要介绍)

• Part I: Bayesian inference (贝叶斯推断)

  • Definition of “probability” ("概率"的定义)
  • Rethink the interpretations (重思概率诠释)
    • Frequentist statistics (频率学派)
    • Bayesian statistics (贝叶斯学派)
  • Bayes' theorem (贝叶斯定理)
    • Application to the detection of gravitational wave (在引力波探测上应用)
  • Bayesian inference framework (贝叶斯推断框架)
    • Parameter estimation for gravitational-wave data (引力波数据分析中参数估计)
    • Model selection for gravitational-wave data (引力波数据分析中模型选择)

• Q & A

• Part II: Bayesian computation (贝叶斯计算方法)

  • Markov Chain Monte Carlo (MCMC; 马尔可夫链-蒙特卡罗方法)
    • hands-on tiny mcmc example
  • Nested sampling (嵌套采样)
    • hands-on tiny nested-sampling example

• Part III: All in gravitational-wave data (一切尽在引力波数据中)

  • Use Bilby & Parallel Bilby in the GW data analysis
  • Show the complete pipeline for the data analysis

• The AMAZING Thomas Bayes (为美好的世界献上"贝叶斯定理")

• Q & A

Here, I recommend using the conda or mamba command to manage your environment. Please make sure you have installed the Miniforge / Miniconda / Anaconda software.

Recommend: you can always replace the conda with the mamba (alternative faster conda) to manage your environment.

You can run

conda --version
mamba --version

to check your conda or mamba environment.

Warning: if you are using the Windows computer, please install WSL2 or use the remote Linux server to obtain the best experience.

To create the full environment, run the following command:

bash ./envs/update_igwn_envs.sh

If your network is blocked, please try

conda env update -f ./envs/igwn-py310-linux-64.yaml

for the Linux x86-64 and Linux amd64 architecture.

For the macOS x86-64 architecture

conda env update -f ./envs/igwn-py310-osx-64.yaml

For the macOS arm64 (Apple silicon)

conda env update -f ./envs/igwn-py310-osx-arm64.yaml

conda create -n igwn-py310 python=3.10 numpy scipy lalsuite pycbc bilby parallel-bilby dynesty emcee jupyterlab ipympl ipywidgets

More advanced commands for conda / mamba can be found at Managing environments
