Hi, thanks for this, we welcome any contributions that can improve this library. Your industry experience will be very helpful. Your can just submit a PR and sign the Salesforce contributor license, and then we will work together with you on this PR.
Hi
I am process Engineer at Orbray .,co, th. I usually analyze my job by using Design of Experiment (DOE) that is tool for root cause analysis in Industials field. But I thought that PyRCA will find root cause as well and accuracy
Hi, we will be appreciated if you can help to bring PyRCA more features and make it more useful in real-world applications. This lib have many components that can be improved, e.g., more RCA methods, supporting more real-world applications, more reliable causal discovery methods.
Hi, I am preparing data for test . But I don't understand about Data of Parent weight. Can you introduce me? . (from the example, parent weight will create route/path). Is it correlation?
Thank you very much

If you apply causal discovery to construct the causal graph, there will no edge weights or parent weights in the graph, only the graph structure. Given the graph, the Bayesian based RCA will build a Bayesian network to infer root causes. The values in the network are the conditional probabilities. Could you explain more about "Parent weight"?
Hi , from your tutorial (Simulated DataGen). Can you check for me? I don't know if I did it correctly. "I can use DataGenConfig to create normal_data, parent_weights, noise_weights, func_form, and noise_form directly from using graph_matrix = graph_df.to_numpy(), right?" .....

Hi there, I'm a data scientist and want to contribute over this project, I have some industry experience and enhancing this project will help industrialists for RCA a lot, how can I connect with you all...
