Hi, Thank you for your interest in our work.
As for the SCAD task, it should be noticed that the input dimension of gene expression and embedding is not the same, as well as the data distribution or other features. Thus, It would be not ideal to use the same hyperparameter setting for both embedding and non-embedding models.
To tackle this problem, we followed the same strategy as described in the SCAD paper: All the hyperparameters were selected based on the prediction performance on the validation set of the source domain. For more information, please refer to their paper and code. Since in the source domain, we also used the embeddings for training, the final hyperparameter would not be the same as the non-embedding one.
As a result, the performance of using the same parameter setting may not be directly comparable. Thus we didn’t analyze in detail how single parameter variation changed the final performance.
Thank you again for your interest in this task. I believe single-cell level drug sensitivity prediction is a future and promising direction.

Thanks for the clarification! Your expertise and effort are highly appreciated! 👍
Hello, its me again! 😀
First, thank you for your efforts in developing and sharing the model.
I was reviewing the demonstration usage provided in the documentation of SCAD, specifically the commands for training the model with and without embedding. Here are the commands for reference:
Without Embedding
With Embedding
I have a concern regarding the significant difference in parameter settings between these two configurations, especially if the goal is to evaluate the impact of embedding on model performance. The variations in
h_dim
,z_dim
,epoch
,lambda1
, and batch sizes might confound the results, making it challenging to attribute performance improvements solely to the use of embedding.Questions:
Understanding the impact of embedding in isolation could provide clearer insights into its effectiveness and potential benefits in drug response prediction models.
Thank you for your time and consideration.
