From Prototype to Production: The Best of Inside the Algorithm
Saison 2 · Épisode 7
mercredi 30 septembre 2026 • Durée 24:41
👉 Discover how Cambridge Spark helps organisations build the data and AI capabilities needed to turn strategy into measurable impact: cambridgespark.com
In this special compilation episode of Inside the Algorithm, host Jeremy, Chief AI Scientist at Cambridge Spark, brings together the best moments from a season of conversations with leading academics, researchers and practitioners. Guests from aviation forecasting, manufacturing, NHS health modelling and neuro-symbolic AI research take on the same core questions. Hearing them side by side shows how experts from very different fields approach the challenge of taking AI from theory to practice.
The episode covers why so many AI projects stall at the prototype stage and where models break when they meet something they've never seen. It also covers how trust is built in systems that can feel like a black box, why the strongest results come from hybrid systems, and what experience still gives you as AI tools take on more of the work.
Key Takeaways
Production readiness means handling edge cases, unforeseen scenarios and adversarial attacks. It also means securing architecture sign-off and making sure outputs reach the people who need them.
Projects succeed when teams understand how a solution will be used and what "done" looks like, and when they have champions inside the client's business.
LLMs learn correlations, not the world. Their reliance on text patterns explains both their surprising capability and their strangest hallucinations.
Historical data has limits. Events like the pandemic can break the relationships forecasting models depend on almost overnight. Stress testing, what-if scenario planning and human domain expertise are essential safeguards.
Trust is built through involvement. Participative modelling earned deep trust with NHS clients in the Midlands, and transferring that trust to new regions proved harder than rebuilding the model itself.
Hybrid systems deliver the strongest results. Pairing language models with solvers, simulations and small, fine-tuned specialist models lets each part do the job it's best at.
Simplicity and production-first thinking win. A working model in production beats a more accurate one that takes months to build. Explainable approaches often serve clients better.
Juniors need the chance to learn the trade. Guests warn about "rubber-stamping" AI-generated code and encourage newcomers to look beyond the hype to the wider history of AI.

No Get Out of Jail Free Card: Five Data Leaders on AI in Regulated Industries
Saison 1 · Épisode 47
mercredi 16 septembre 2026 • Durée 24:52
👉 Discover how Cambridge Spark helps organisations build the data and AI capabilities needed to turn strategy into measurable impact: cambridgespark.com
In financial services, getting AI wrong doesn't just mean a bad headline. It means real customers losing real money at the moments that matter most.
If you're trying to balance AI innovation with regulatory scrutiny, you already know the tension: move too fast and risk a compliance failure, move too slow and watch competitors who don't hesitate pull ahead.
Edmund Towers leads Advanced Analytics & Data Science at the Financial Conduct Authority, shaping the regulator's approach to AI, financial crime detection and consumer protection. Before joining the FCA, he delivered financial services transformation programmes as a manager in Accenture's Financial Services Change Practice. In this compilation episode, he's joined by Jessica Rusu, the FCA's Chief Data, Information and Intelligence Officer, alongside senior data leaders from Santander UK, Aviva and TalkTalk.
You'll hear how the FCA thinks about AI governance without resorting to tick-box regulation, and how banks and insurers turn that clarity into production systems. Sarah Self at Aviva explains how a summarisation tool cut claims hold times by more than 50%. Kevin Cassar walks through building an AI triage system in health insurance that improved both customer outcomes and operational efficiency.
This episode covers the FCA's AI Live Testing programme, the Consumer Duty as the policy anchor for responsible AI, and how Santander UK's Luke Pearce secured C-suite sponsorship to move faster on generative AI. It's built for data and AI leaders in regulated industries who need to make the business case for AI while keeping compliance onside, and for anyone who assumes regulation and innovation have to be at odds.
Key Takeaways
Edmund Towers explains why the FCA's AI Live Testing lets firms trial live products under supervision, and why it's built on guidance rather than a tick-box checklist.
DAIM: Inside The Algorithm | Divya Kesavan on AI Transformation in Banking: Beyond RPA and Automation
Saison 2 · Épisode 6
mercredi 2 septembre 2026 • Durée 31:36
👉 Discover how Cambridge Spark helps organisations build the data and AI capabilities needed to turn strategy into measurable impact: cambridgespark.com
For years, digital transformation and AI transformation have been used almost interchangeably. Divya Kesavan, Head of Data Science for Business and Commercial Banking at Lloyds Banking Group, explains why that conflation breaks down in practice.
In this episode, Divya walks Jeremy through the shift from rule-based RPA to reasoning-driven AI and why Lloyds' enterprise AI blueprint rests on three layers: reasoning, context and control. She unpacks what it actually takes to move an agentic system from a working proof of concept to a tool trusted with real banking decisions, including a striking example of an AI agent that went badly off script.
The conversation also covers governance by design in a heavily regulated environment, confidence scoring as a practical risk tool, and why agile alone cannot carry the weight of AI-led change. A grounded, experience-based look at what transformation really requires.

What does it actually take to ship machine learning inside one of the UK's largest insurers? Jeremy Bradley sits down with Alberto Romero, director of AI engineering at Aviva, to trace his path from InsurTech founder to enterprise AI leader.
Alberto explains why prototypes are so often mistaken for finished products and what production readiness really demands once edge cases, drift and adversarial behaviour enter the picture. The conversation covers how to get genuine explainability out of large language models rather than plausible-sounding justification, when fine-tuning earns its place in a regulated stack, and why Aviva built its own internal platform to govern AI use cases at scale.
Alberto also shares his take on fraud detection as an adversarial ML problem and the one failure mode he sees engineering teams repeat most often.

Fast Enough to Matter, Careful Enough to Trust: How Leaders Are Governing AI
Saison 1 · Épisode 45
mercredi 22 juillet 2026 • Durée 31:38
👉 Discover how Cambridge Spark helps organisations build the data and AI capabilities needed to turn strategy into measurable impact: cambridgespark.com
There's a real difference between an organisation experimenting with AI and one that has genuinely thought through what it means for its strategy, its accountability, and the people it serves. That gap is where a lot of the frustration lives.
In this episode, we bring together some of the sharpest thinking from across the show on AI strategy and governance: the decisions that happen before AI gets deployed and the frameworks that make sure it keeps working once it does.
You'll hear from Luke Pearce, Chief Data Officer at Santander UK, on presenting AI governance at the board level. From Miryem Salah at VodafoneThree, on building an AI strategy from first principles. And from senior leaders at Aviva, Oxford Saïd Business School, and Intact Insurance, all grappling with the same fundamental question: how do you move fast enough to stay relevant, but carefully enough to stay trusted?

👉 Discover how Cambridge Spark helps organisations build the data and AI capabilities needed to turn strategy into measurable impact: cambridgespark.com
Large language models are surprisingly good at producing fluent, plausible text. So why do they still confidently get simple things wrong?
In this episode, Dr Jeremy Bradley is joined by Dr Vaishak Belle, Reader at the University of Edinburgh's School of Informatics, Alan Turing Institute Faculty Fellow and Director of Research and Innovation at the Bayes Centre. Vaishak has spent 16 years working at the intersection of logic, probability and machine learning and brings that lens to one of AI's most persistent problems: hallucination.
The conversation traces why scaling alone will not solve reliability, what neurosymbolic AI actually is and why tools like Claude Code quietly depend on it, how theory of mind is being engineered into language models, and where reinforcement learning fits into the future of AI reasoning.
If you work at the frontier of AI research or engineering, this is a grounded, technically rich conversation worth your time.

The technology is the easy part. Getting people ready for it, that's the hard part.
In this special compilation episode, Dr Raoul-Gabriel Urma steps back from the individual conversations and zooms out to one of the most persistent themes across the show in 2026: AI skills and literacy. Because no matter the industry, the company size, or the stage of the AI journey, the same challenge keeps surfacing. How do you get an entire workforce genuinely ready?
You'll hear from Jessica Rusu, Chief Data, Information and Intelligence Officer at the FCA, on building T-shaped skills for an uncertain future. From Nick Edwards and Harj Johal at the AA on the combination of tooling, training, and space to practise that has driven rapid, organisation-wide progress. From Sarah Self at Aviva on why democratising AI is as much a cultural imperative as a commercial one. And from senior data and AI leaders at Santander UK, Oxford Saïd Business School, and TransUnion on curiosity, fear, and what genuinely high-performing teams look like in an era of AI.
A compelling, cross-industry episode for anyone thinking about the people side of AI transformation. These, however, are just the highlights. Find links to every full episode below:

This week, Dr Judit Guimera Busquets, Head of Data Science at Datasparq, joins Dr Jeremy Bradley to trace the journey from her PhD on air traffic network forecasting through to leading data science teams delivering real-world AI projects.
Judit explains why forecasting inside a complex network is fundamentally different from standard demand prediction: when a single airport pair is removed, the cascade effect ripples across an entire system. She walks through the multi-stage modelling framework she developed, covering city pair demand generation, network evolution, itinerary assignment, and long-term scenario planning.
The conversation then turns to what actually happens when structural shocks like a pandemic break a model's core assumptions and why human-in-the-loop design is not optional. Judit also sets out what she looks for in data scientists: pragmatism over perfection, simplicity over complexity, and a production-first mindset from day one.
She closes with her view on where applied AI is heading, including the rise of small, fine-tuned specialist models and why AI governance remains the most overlooked challenge in the field.
