- The overall idea relating symplectic structures with quantum optimal transport appears to be novel.
This work purported to introduce a "groundbreaking unified theory for Drug-Target Interaction prediction with Domain Adaptation (DTI-DA) that bridges the gap between quantum mechanics, information theory, and statistical learning". To achieve this, it proposed to use a novel symplectic structure that captures the information geometry of DTIs. While this appears to be an interesting direction, the main text consists mostly of derivations of quantities without context. It is also unclear how the derivations relate the application that the manuscript sought to address, which is DTI. Perhaps the manuscript did make some important breakthroughs but these have unfortunately not shown with the text provided.
- The presentation does not make it clear how the "unified variational principle" was used in model training or how it was related to the model architecture (Figure 1), which also uses very "antiquated" modules (GAT and KAN).
- The experiments were far from adequate: there should have been multiple runs (for uncertainty quantification) and more "modern" baselines to compare with.
- Typo in Figure 2: the $ x $-labels should have been in the other direction.

* What is the computational complexity of implementing the quantum optimal transport?
* How does the model handle low precision numerics in quantum channel calculations?
   * For example, if someone uses mixed precision training (bf16/fp32) instead of fp32.
* Please fix the formatting issue with the references. Some references have a white spaces and some don't have it. 
  * Knowledge Aware Network's reference on L134 is wrong.
* Comprehensive theoretical foundation combining multiple mathematical frameworks (quantum mechanics, differential geometry, information theory) in a novel way
* Mathematical proofs and derivations, particularly in sections 2.1-2.4
The authors introduce a comprehensive unified theory for Drug-Target Interaction prediction with Domain Adaptation (DTI-DA), integrating quantum mechanics, differential geometry, and information theory. The authors develop a novel framework use a DTI symplectic structure that captures molecular interaction geometry and a quantum statistical mechanical formulation incorporating DTI-preserving quantum features. 
The implementation architecture consists of two main components: a Graph Attention Network (GAT) for adaptive neighbor attention and a Knowledge-Aware Network (KAN) for structural optimization. Experimental validation was conducted on two datasets: BioSNAP and BindingDB.

On the BioSNAP dataset DTI-DA model achieved an AUC of 0.744 (2.66% improvement over baseline), AUPR of 0.757 (3.42% improvement), and accuracy of 0.659 (3.71% improvement). Performance on the BindingDB dataset was also strong, with improvements of 8.11% and 9.075% over SVM and RF baselines respectively.
* Limited ablation studies and theoretical complexity may limit practical implementation.
* Experiments are conducted with just datasets. An interesting benchmark would be Merck FEP (https://chemrxiv.org/engage/chemrxiv/article-details/60c747cc469df43efff438b9)

The prediction of drug-target interactions is fundamental to the advancement of drug discovery. We present a groundbreaking unified theory for Drug-Target Interaction prediction with Domain Adaptation (DTI-DA), seamlessly integrating concepts from quantum mechanics, differential geometry, and information theory. Our framework introduces a novel DTI symplectic structure that captures the intrinsic geometry of drug-target interactions, leading to a Quantum Optimal Transport theorem that provides a rigorous foundation for domain adaptation in the DTI context. We develop a quantum statistical mechanical formulation of DTI-DA, introducing DTI-preserving quantum channels and deriving a Quantum Wasserstein distance tailored to drug discovery applications. Our information-geometric perspective yields a Quantum Fisher-Rao metric for DTI, resulting in a quantum Cramer-Rao bound that establishes fundamental limits on DTI prediction accuracy. We propose a unified variational principle for DTI-DA, encompassing quantum and classical aspects, which leads to a novel algorithm based on geometric stochastic gradient Langevin dynamics. Furthermore, we extend classical statistical inference to the quantum domain, deriving a Quantum Rao-Blackwell theorem and a Quantum Bayesian Cramer-Rao bound specifically for DTI-DA. These theoretical advancements not only deepen our understanding of the DTI-DA problem but also suggest new algorithmic approaches with provable guarantees. Preliminary numerical experiments on quantum-inspired DTI-DA algorithms demonstrate significant improvements in prediction accuracy and domain adaptation capabilities compared to classical methods, particularly for challenging out-of-distribution scenarios in drug discovery.
