Community-Federated Conference (CFC)

• Community-Federated Conference (CFC) is a decentralized meeting model that separates peer review, local presentation, and digital networking.
• It employs a three-layer structure—global peer review, federated regional hubs, and synchronized online sessions—to enhance accessibility and sustainability.
• Quantitative metrics show a 90% emission reduction, reduced travel distances, and improved equity compared to centralized conference models.

The Community-Federated Conference (CFC) is a paradigm for scientific convening that reorganizes a large-scale, single-site conference into a globally coordinated but locally decentralized structure. Introduced as a response to the escalating scientific, logistical, environmental, and psychological strains of the prevailing centralized AI conference model, the CFC approach separates peer review, presentation, and networking into distinct but interconnected layers. This structure is quantitatively argued to improve sustainability, equity, and operational resilience in scientific dissemination, particularly within AI research (Chen et al., 6 Aug 2025).

1. Structural Principles and Layered Architecture

The CFC model consists of three functionally decoupled but synchronized layers:

1. Global Peer Review & Publication: Submissions are managed through a year-round, rolling deadline system via a consortium-operated digital platform. This platform orchestrates reviewer assignments, enforces review fairness, and publishes accepted works in an ongoing, citable proceedings volume, distinct from conventional fixed conference cycles.
2. Federated Regional Hubs for Presentation: Authors whose papers are accepted select a geographically proximate hub, typically hosted by universities or scientific societies, for in-person presentation. Each hub accommodates 500–1,500 participants, offering reduced travel distances, minimized costs, and substantially lower carbon emissions while enhancing accessibility and local scientific community development.
3. Digital Synchronization and Networking: A unified digital infrastructure streams plenary sessions from a rotating anchor hub to all locations, supports online poster halls, and enables distributed, asynchronous interaction via thematic communication channels (e.g., Slack or Discord). This ensures cross-hub discourse and global network effects are preserved.

These principles instantiate a many-to-many mapping between conference goals and logistical operations. Peer review is dissociated from physical event timing, supporting fairness and reducing review and submission deadlines. Local presentations enable scalable in-person engagement without exceeding single-venue capacities, while the federated networking layer maintains the inclusive, global reach essential for impactful scientific exchange (Chen et al., 6 Aug 2025).

2. Mathematical Models and Key Performance Metrics

CFC advances are quantified relative to the failures of the centralized model, using formal metrics and explicit formulas:

• Per-Author Publication Rate:

$r_p = \frac{P_{\mathrm{total}}}{A}$

where $P_{\mathrm{total}}$ is the accepted paper count and $A$ the number of unique authors. In AI, this rate has risen from ≈2 to >4.5 papers per author annually over the past decade.

• Conference Carbon Footprint:

Centralized model:

$$C_{\mathrm{central}} = N_{\mathrm{att}} \times \overline{D} \times f_{\mathrm{air}} = N_{\mathrm{att}} \times E_{\mathrm{avg}}$$

where $N_{\mathrm{att}}$ is the total attendee count, $\overline{D}$ is mean round-trip travel distance, and $f_{\mathrm{air}}$ is emissions per km. NeurIPS 2024's estimate was $C_{\mathrm{central}} \approx 8,254$ tCO₂e.

CFC model (per hub $h$):

$$C_{\mathrm{hub}} = N_{\mathrm{hub}} \times \overline{d}_{\mathrm{hub}} \times f_{\mathrm{air}}$$

with substantially lower $P_{\mathrm{total}}$0 compared to $P_{\mathrm{total}}$1.

• Venue-Capacity Logistic Model:

$P_{\mathrm{total}}$2

where $P_{\mathrm{total}}$3 is venue capacity, and $P_{\mathrm{total}}$4 the projected attendance. CFC eliminates single-venue bottlenecks by distributing delegates across hubs, each operating below capacity.

Quantitative gains are summarized in the following table:

Metric	Centralized Model	CFC Model (10 hubs)	Improvement
CO₂e footprint $P_{\mathrm{total}}$5	8,254 tCO₂e	~825 tCO₂e	90% reduction
Mean travel distance	7,500 km	1,200 km	–83%
Community negativity (Reddit)	71% negative	~25% negative	–65%
Equity of participation	18% low-income	45% underrepresented	+150%
Venue-capacity violations	frequent lotteries	none	complete fix

Improvement ratios are determined via: $P_{\mathrm{total}}$6 (Chen et al., 6 Aug 2025).

3. Federated Coordination Protocols

Federated operation requires robust global-local coordination. The CFC model posits two main forms:

• Rolling Decentralized Review Assignment: Submissions are dynamically matched to reviewers, balancing load and subject expertise, and observing conflict-of-interest constraints. Maximum loads are respected per reviewer per cycle. Accepted works are published in rolling volumes.

$P_{\mathrm{total}}$7

• Local Hub Scheduling: Each hub creates a conflict-free, parallel-track schedule. A greedy algorithm assigns accepted presentations to the earliest feasible slots, optimizing for topic coherence and capacity.

$P_{\mathrm{total}}$8

Plenary sessions remain globally synchronized, with digital infrastructure bridging all hubs (Chen et al., 6 Aug 2025).

4. Scientific and Societal Impact

CFC directly targets four axes of unsustainability present in the centralized conference paradigm:

• Scientific Overload: With per-author rates exceeding 4.5 papers/year and trending towards 12 by 2030, bottlenecked review cycles degrade evaluation quality. CFC’s rolling review aims to reduce deadline-induced stress and recalibrate publication incentives.
• Environmental Burden: A single conference now produces emissions comparable to a host city's daily output. CFC’s distributed hubs effectuate a calculated 90% emissions reduction.
• Psychosocial Strain: Analysis of online discourse revealed 71% negative sentiment and 35% referencing mental health concerns, often ascribed to deadline compression and logistical overload. CFC’s decoupling of review and presentation, alongside improved local accessibility, yields markedly lower negativity.
• Access and Capacity: Large centralized conferences increasingly resort to lottery-based attendance control, and participation from low-income and underrepresented regions remains low. CFC achieves uniform hub-level attendance and, empirically, a 150% gain in inclusion from such regions (Chen et al., 6 Aug 2025).

5. Operational and Implementation Considerations

Deployment of CFC entails substantial shifts:

• Governance: An international consortium must manage the global review platform, prompting challenges in policy standardization, oversight, and resourcing.
• Technical Consistency: Local hubs require adherence to common guidelines for audiovisual setups, scheduling, and poster presentation; implementation may require targeted seed funding.
• Digital Infrastructure: Persistent online halls and live streaming must reliably scale to thousands of parallel users, demanding robust and redundant back-end support.
• Cultural Transition: Adoption necessitates alteration of entrenched research community behaviors regarding timelines, hub preference, and networking modes. Incentive structures like travel grants and expedited review cycles may facilitate early uptake.

Future extensions outlined include dynamic hub creation (triggered by demand), hybrid sub-field clustering, and equity-aware author–hub assignments within scheduling and review protocols (Chen et al., 6 Aug 2025).

6. Outlook and Theoretical Generalization

The CFC proposal delivers a quantitative and procedural blueprint for transitioning toward a federated, scalable, and sustainable conference system. By physically decoupling the components—evaluation, presentation, and discourse—it enables each to be optimized according to distinct scientific and community objectives. The model formally addresses the foundational goals of scientific rigorousness, environmental stewardship, equity of participation, and community resilience. Its principles and structures provide a referential framework for other fields considering the federation of large academic meetings, with adaptability for further dynamic or hybridization strategies (Chen et al., 6 Aug 2025).
