THREE PRACTITIONER INSIGHTS . 01 We evaluated 6 platforms. Here's the question that decided it. We spent two months evaluating AI/ML platforms, Dataiku, Azure ML, SageMaker, Vertex AI, and two niche players. Feature matrices. Benchmark tests. Vendor presentations. After all of that, the deciding question was surprisingly simple: "Which one can...

THREE PRACTITIONER INSIGHTS . 01 My most valuable team member doesn't write code. She's a former business analyst who spent eight years in our lending division. She knows every process, every pain point, every stakeholder's real concern (not the one they say in meetings, the one they whisper in the corridor). When a business unit comes to us with "we want...

THREE PRACTITIONER INSIGHTS . 01 We over-classified 60% of our AI systems. Then we spent two weeks fixing it. When the EU AI Act requirements first crystallized, my team's instinct was caution: classify everything as high-risk, apply maximum governance, protect the bank. The result was absurd.

THREE PRACTITIONER INSIGHTS . 01 DORA turned our LLM provider into a systemic risk. We didn't see it coming. When we first integrated an external LLM API into a business-critical workflow, nobody flagged DORA implications. It was an "AI project," not an "ICT risk" issue. Then our DORA compliance team started their critical-vendor assessment and...

THREE PRACTITIONER INSIGHTS . 01 Our governance framework fits on one page. Here's what's on it. Three questions. That's the entire framework. (1) What risk tier is this? Low = internal-only, no client impact, reversible. Medium = indirect client impact or regulatory relevance. High = direct decisions about clients, money, or compliance. (2) What...

THREE PRACTITIONER INSIGHTS . 01 We spent 6 weeks on the model. We spent 6 months on the data pipeline. This is normal. I used to present this ratio apologetically, like it was a failure of planning. Now I present it as a law of nature. In regulated banking, data access involves security reviews, privacy impact assessments, data-sharing agreements...

From delving into the intricacies of neural networks to uncovering hidden patterns in large datasets, every day presents new challenges and opportunities for learning. This week, I want to share something a little different, yet equally crucial—how to handle skepticism and challenges during presentations and meetings. A shift from last week's...

Yes, data science never fails to invigorate my intellectual curiosity! This week, let's pivot a bit. We often discuss the skills you must cultivate to succeed in data science. But what about the things you...

The Power of AI by Christophe Atten Good morning Reader, Another week, another whirlwind of AI developments, left me intrigued, inspired, and a tad overwhelmed (in a good way). What have I been up to this week? Between leadership meetings and five cups of coffee, I've been digging into the advancements in AI tech that could redefine how we live and work. As someone perpetually looking for transformative trends in AI, I've been immersed in my research lately. Sifting through tech developments...

The Power of AI by Christophe Atten Good morning Reader, Do you ever have those days where you're handed a challenge that makes you question everything you know? That was me recently. I was given the monumental task of envisioning the future of AI within the finance sector. Oh, the nostalgia! It took me back to the time I was working on a similar strategy as support, only to find myself now leading the charge as the Data Science Manager. How time flies, right? I poured myself a cup of coffee...
