Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

With regards,

Finding Order in Flight Chaos

Finding Order in Flight Chaos

The recent news about the IndiGo crisis, with widespread flight cancellations and the airline seeking an external expert to identify the root cause of the chaos, has truly resonated with me IndiGo crisis: External expert to identify root cause of chaos; more trouble for airline. It brings to mind the fundamental challenge of sifting through vast amounts of unstructured data to find meaningful patterns and understand underlying issues.

I’ve spent considerable time contemplating how intelligent systems could tackle such complexities. Back in 1996, I conceptualized ARDIS (Automatic Resume Deciphering Intelligence Software) and ARGIS (Automatic Resume Generating Intelligence Software) – systems designed to parse and generate structured data from free-form text, using a knowledge base and probability models ARDIS, A 29 Year Old Dream. I was exploring how to 'decipher' key data from unstructured resumes, a logic that both BARD and ChatGPT later affirmed as a foundational, albeit crude, form of Natural Language Processing (NLP) 27 Years Ago: Foundation of NLP.

BARD, for instance, noted that my logic for deciphering information like telephone numbers and company names was a common approach in NLP, providing a good starting point for more robust systems. ChatGPT echoed this, highlighting my early attempts at pattern recognition and rule-based methods for information extraction, entity recognition, and even taking into account syntax and context.

The core idea I wanted to convey then, and which feels remarkably relevant now, is this: to truly understand a chaotic situation like the IndiGo disruptions, one needs a system capable of more than just superficial analysis. An external expert, however brilliant, can only process so much information. The real power lies in an AI system that can learn from the myriad of inputs.

Consider the operational data of an airline: flight schedules, crew rosters, aircraft maintenance logs, spare parts inventory, ground staff availability, passenger booking patterns, weather forecasts, air traffic control directives, and even real-time social media sentiment. This is an enormous, interconnected web of data, much of it unstructured or semi-structured. My earlier work, particularly the concept of ARDIS with its focus on pattern recognition, rule-based processing, and information extraction, offers a blueprint. An advanced iteration of such a system could:

  • Analyze Disparate Data Sources: Automatically ingest and correlate data from flight manifests, maintenance records, crew fatigue reports, weather advisories, and passenger complaints (as detailed in articles like IndiGo crisis: External expert to identify root cause of chaos; more trouble for airline).
  • Identify Hidden Patterns: Go beyond obvious causes to uncover subtle interdependencies – for instance, a cascading effect of delayed maintenance leading to multiple crew duty-time violations, amplified by unexpected weather shifts.
  • Predict Future Bottlenecks: By continuously updating its probability models, much like my proposed self-learning software from 2003 Child trains AI ?, it could foresee potential disruptions before they escalate into a crisis.
  • Propose Actionable Solutions: Instead of merely identifying a problem, such an AI could suggest optimal re-routing, crew rescheduling, or maintenance prioritization to mitigate impact.

Reflecting on it today, it's striking how relevant those earlier insights still are. I had already predicted the challenge of extracting intelligence from complex data and even proposed a solution at the time, albeit for a different domain. Now, seeing how things have unfolded with the IndiGo crisis, there's a renewed urgency to revisit those ideas. The need for robust, self-learning systems that can identify the true 'grammar' and 'logic' behind operational chaos is more apparent than ever.
