Join us this week for an in-depth discussion on Compositional Learning in the context of cutting-edge text-to-image generative models. We will explore recent breakthroughs and challenges, focusing on how these models handle compositional tasks and where improvements can be made.
✅ This Week's Presentation:
🔹 Title: A semiotic methodology for assessing the compositional effectiveness of generative text-to-image models
🔸 Presenter: Amir Kasaei
🌀 Abstract:
A new methodology for evaluating text-to-image generation models is being proposed, addressing limitations in current evaluation techniques. Existing methods, which use metrics such as fidelity and CLIPScore, often combine criteria like position, action, and photorealism in their assessments. This new approach adapts model analysis from visual semiotics, establishing distinct visual composition criteria. It highlights three key dimensions: plastic categories, multimodal translation, and enunciation, each with specific sub-criteria. The methodology is tested on Midjourney and DALL·E, providing a structured framework that can be used for future quantitative analyses of generated images.
Session Details:
- 📅 Date: Sunday
- 🕒 Time: 5:00 - 6:00 PM
- 🌐 Location: Online at vc.sharif.edu/ch/rohban
We look forward to your participation! ✌️

✅ This Week's Presentation:
🔸 Presenter: Amir Kasaei
🌀 Abstract:
Recent advancements in text-conditioned image generation, particularly through latent diffusion models, have achieved significant progress. However, as text complexity increases, these models often struggle to accurately capture the semantics of prompts, and existing tools like CLIP frequently fail to detect these misalignments.
This presentation introduces a Decompositional-Alignment-Score, which breaks down complex prompts into individual assertions and evaluates their alignment with generated images using a visual question answering (VQA) model. These scores are then combined to produce a final alignment score. Experimental results show this method aligns better with human judgments compared to traditional CLIP and BLIP scores. Moreover, it enables an iterative process that improves text-to-image alignment by 8.7% over previous methods.
This approach not only enhances evaluation but also provides actionable feedback for generating more accurate images from complex textual inputs.
Session Details:

Adversarial robust learning and its generalization issues
This is a research project in the group of Dr. Rohban (RIML lab) from Sharif University of Technology
Project description:
Despite deep neural networks impressive success in many real-world problems, their instability under test-time adversarial noises is the major issue against their use in safety-critical applications. Therefore, the problem of learning robust deep networks (not only accurate on original samples, but also accurate on adversarially perturbed ones) has become an active area of research.
Training the model based on the adversarial samples in each mini-batch, which is known as “Adversarial training” (AT), has been empirically established as a general and effective approach to remedy this issue. However, real challenges in practice and also theoretical aspects have remained. Especially, we face some critical generalization issues in this new learning paradigm including the larger generalization gap between test and train data in comparison with standard training or the specific phenomenon called catastrophic overfitting. Achieving a better understanding of this topic can be a good help to provide more robust models.
In this project, we aim to analyze generalization in robust learning in a more comprehensive, deep, and detailed way. The project has both theoretical and practical aspects; So having interest, capability, and perseverance in both aspects is needed.
Estimated time for the project is 6 months although it may change depending on the progress and results of the project.
For more information, you can read the following paper:
Zerograd: Costless conscious remedies for catastrophic overfitting in the FGSM adversarial training
Requirements:
- Familiarity with linear algebra fundamentals
- Familiarity with statistics and probability
- Familiarity with ML and deep learning fundamentals
- Hands-on experience in ML and deep learning
- Hands-on experience with PyTorch framework
- Dedicating considerable time and consistency to the project
- Enthusiasm to learn and tackle research problems
Preferred qualifications:
* Familiarity with Jax framework
Familiarity with adversarial robustness
