For today’s AI professionals, looking back at AAAI is not just about “understanding history,” but about seeing how AI research has gradually progressed from laboratories to industry, from algorithms to systems, and from capabilities to governance.

If one were to select the most representative academic conference in the history of artificial intelligence, AAAI would almost certainly appear at the top of the list.

It is not just a regular conference, but an ever-evolving "documentary on the evolution of AI." From early logic reasoning and knowledge representation, to machine learning and deep learning, and now to large models, agents, and trustworthy governance, the evolving topics of AAAI serve as a time capsule of academic research in artificial intelligence.

For today’s AI professionals, looking back at AAAI is not just about “understanding history,” but about seeing how AI research has gradually progressed from laboratories to industry, from algorithms to systems, and from capabilities to governance.

I. The Origin of AAAI: AI Begins to Take Shape as an Independent Discipline

When AAAI was founded, artificial intelligence was far from the spotlight it enjoys today.

At that time, the most pressing question researchers cared about was simple: Could machines think like humans? Could they reason? Could they make decisions?

In addressing these issues, early AI research was primarily grounded in symbolic approaches, focusing on knowledge representation, logical reasoning, planning, and problem solving. The emergence of AAAI brought together previously fragmented research efforts into a stable platform, helping artificial intelligence gradually evolve from a "conceptual imagination" into an "independent discipline."

In other words, AAAI is not just documenting the history of AI—it has actively helped shape it.

II. The Era of Expert Systems: Artificial Intelligence Makes Its First Real-World Applications

After entering the expert system phase, AI no longer merely “proves that machines can think,” but begins to attempt “making machines truly help people get things done.”

During this phase, AAAI research shifted toward knowledge engineering: how to transform human experts’ experience, rules, and judgments into machine-executable systems for practical applications such as medical diagnosis, industrial decision-making, and engineering troubleshooting.

This is the first time artificial intelligence has truly come close to the real world.

However, expert systems quickly revealed limitations: the rules were overly dependent on manual maintenance, knowledge acquisition was costly, and the systems had limited scalability. It was under these constraints that AI research began to seek new directions, gradually shifting toward data-centric approaches.

III. The Rise of Machine Learning: AI Moves from "Writing Rules" to "Learning Patterns"

If AI in the expert systems era was like "encoding experts' knowledge into machines," then the advent of the machine learning era means AI has begun to learn how to find patterns in data on its own.

This is a fundamental paradigm shift.

From decision trees and support vector machines to probabilistic graphical models, pattern recognition, and data mining, AAAI witnessed AI's transition from rule-driven to statistics-driven approaches. From then on, artificial intelligence no longer relied primarily on manually coded logic, but instead trained models using data to automatically extract features, identify patterns, and perform predictions and decisions.

This step is crucial because it enables AI to truly expand into the real world.

IV. The Deep Learning Era: AI Enters a Period of Large-Scale Explosion

The rise of deep learning has ushered artificial intelligence into a truly scalable era.

Compared to traditional machine learning, deep learning has stronger capabilities in complex feature representation, multimodal modeling, and large-scale training, thereby rapidly driving breakthroughs in fields such as speech recognition, visual recognition, and natural language processing.

During this period, AAAI's research focus also shifted: areas such as neural network architecture optimization, large-scale representation learning, multimodal fusion, and transfer learning continued to gain momentum. The conference evolved from being merely a platform for showcasing individual algorithms to becoming a centralized venue for unveiling complex intelligent systems.

If the previous stage of AI focused on "whether it can learn," then the era of deep learning asks: can it learn bigger, faster, and broader?

Five: The Era of Large Models — AI No Longer Pursues Only "Stronger," But Also "More Stable"

In recent years, with the explosion of large models and generative AI, the academic research represented by AAAI has entered a new phase.

Today’s AI is no longer just about improving performance metrics; it places greater emphasis on reliability, security, and governability in real-world deployment. In other words, the research question has shifted from “Can the model be built?” to “Can the model safely, stably, and sustainably operate over time?”

Thus, AAAI's focus has also expanded to:

Large model reasoning capability
Agent Development
Model alignment
Robustness
Explainability
Trustworthy governance

This means that AI research is transitioning from a "capability competition" to a "system competition." Those who can not only perform strongly but also operate stably, sustainably, and reliably are closer to the core direction of the next generation of AI.

Six: Looking at the three AAAI conferences together: It’s not just a change of city, but an evolution in the conference format

If you look at AAAI-24, AAAI-25, and AAAI-26 together, you'll notice that the differences between them go far beyond just different host locations.

What is truly changing is the structure, agenda, speaker lineup, and sponsorship model of the conference. In other words, AAAI is gradually evolving from a traditional academic conference into a more comprehensive international technology platform.

This table most clearly shows the differences among the three conferences:

The most important significance of this table is not simply to tell you "which year was bigger," but to show you that AAAI's upgrade is structural.

AAAI-24 resembled the recovery and expansion of a mature platform; AAAI-25 significantly strengthened focus on generative AI, agents, and cross-modal trends; by AAAI-26, the conference further exhibited a composite character of platformization, ecosystem development, and internationalization.

In other words, AAAI is no longer just a place for publishing papers, but is evolving into a comprehensive hub that brings together research, industry, and governance discussions.

Seven: The True Value of AAAI — It Records Not Just Technology, But the Direction of AI

Looking back at the development of AAAI, you'll find it has always been answering the same question:

Where should artificial intelligence head next?

From symbolic approaches to data-driven methods, from single-point algorithms to systemic capabilities, from outcome-oriented to trust-oriented goals, AAAI documents the continuous self-renewal of AI research.

And this evolution path also makes it clear to us that:

The artificial intelligence of the future will not be defined solely by “larger models” or by “higher scores.” It will ultimately be defined by its ability to truly become a stable, trustworthy, and sustainable technological system that serves the real world.

This is precisely the enduring value of conferences like AAAI—

It not only shows the present, but more importantly, defines the future in advance.
