International Conference on Learning Representations (ICLR): A Deep Dive
The International Conference on Learning Representations (ICLR) stands as a pivotal event in the landscape of machine learning, consistently drawing together researchers and practitioners from both academic and industrial spheres. Since its inception in 2013, ICLR has distinguished itself through its commitment to open peer review, a model championed by Yann LeCun. This article delves into the essence of ICLR, exploring its structure, significance, and contributions to the field of deep learning.
Overview of ICLR
ICLR is an annual machine learning conference typically held in late April or early May. It serves as a forum for the presentation and discussion of cutting-edge research in the field of representation learning, encompassing a broad spectrum of topics within deep learning. The conference program features invited talks, oral presentations, and poster sessions, providing multiple avenues for researchers to share their work and engage with the community.
Open Peer Review Process
A defining characteristic of ICLR is its adoption of an open peer review process. Utilizing platforms like OpenReview, ICLR fosters transparency and encourages public discussion of submitted papers. This process allows anyone to view papers and participate in discussions. Reviewer comments are visible, though reviewers remain anonymous. Authors can revise their papers multiple times before the submission deadline and during the discussion phase, with changes tracked for transparency. This approach aims to promote rigorous evaluation and constructive feedback, ultimately improving the quality of published research. The papers and public discussions are hosted on OpenReview.
Key Aspects of Paper Submission
ICLR has specific guidelines and deadlines for paper submissions. For example, in the past, authors were required to submit paper abstracts by a certain deadline, with full paper submissions due a week later. Crucially, no changes to the authors or their order were permitted after the abstract submission deadline. This policy ensures the integrity of the submission process and prevents authorship disputes.
Conference Locations and Dates
ICLR has been held in various locations around the world. For instance, The Twelfth International Conference on Learning Representations (ICLR) was held in Vienna Austria, May 7--11, 2024. ICLR 2025 took place in Singapore from April 24 to 28. These locations reflect the global reach and impact of the conference.

Research Presented at ICLR
ICLR serves as a platform for organizations like Apple to present their latest research in machine learning and related fields. The research presented spans a wide range of topics, including:
Vision Language Models: FastVLM, a family of mobile-friendly vision language models, utilizes a mix of CNN and transformer encoding techniques. These on-device models are designed for applications like chatbots, captions, and image finders.
Monocular Depth Estimation: Depth Pro enables zero-shot monocular depth estimation from images without needing camera information during training. It can generalize to various images and uses a query-based architecture for state-of-the-art vision transformer modeling.
The Significance of Representation Learning
The conference's focus on representation learning is particularly relevant in the context of modern machine learning. Representation learning aims to discover effective ways to represent data, enabling machine learning models to learn complex patterns and make accurate predictions. This field encompasses techniques such as feature learning, deep learning, and embedding methods.
Conceptual Role Semantics and In-Context Learning
Recent research presented at ICLR explores how large language models (LLMs) reorganize their representations based on context. This work investigates whether models can alter pretraining semantics to adopt alternative, context-specified ones through in-context learning. By providing in-context exemplars where a concept plays a different role than its pretraining suggests, researchers analyze whether models reorganize their representations accordingly.

Graph Tracing Task
One approach to studying this phenomenon involves a "graph tracing" task. In this task, the nodes of a graph are referenced via concepts seen during training (e.g., apple, bird), and the connectivity of the graph is defined via a predefined structure (e.g., a square grid). By providing exemplars that indicate traces of random walks on the graph, researchers can analyze the intermediate representations of the model.
Re-organization of Representations
Studies using this approach have found that as the amount of context is scaled, there is a re-organization from pretrained semantic representations to in-context representations aligned with the graph structure. However, when reference concepts have correlations in their semantics (e.g., Monday, Tuesday), the context-specified graph structure may be present but unable to dominate the pretrained structure.
Energy Minimization Analogy
To explain these results, researchers have drawn an analogy to energy minimization for a predefined graph topology, suggesting an implicit optimization process to infer context-specified semantics. This perspective provides insights into how LLMs adapt their representations based on contextual information.
ICLR and the Broader AI Landscape
ICLR is closely related to other major conferences in the field of artificial intelligence, such as the International Conference on Machine Learning (ICML) and the European Conference on Computer Vision (ECCV). These conferences share a common goal of advancing the state-of-the-art in AI and related disciplines.
Relationship to ICML and ECCV
ICLR, ICML, and ECCV each have their own unique focus and strengths. ICML emphasizes a broad range of topics in machine learning, artificial intelligence, statistics, and data science. ECCV focuses specifically on computer vision, bringing together researchers and practitioners in this area. ICLR, with its emphasis on representation learning, bridges the gap between these fields, providing a forum for exploring the fundamental principles that underlie effective machine learning systems.
