The 5 lessons anyone could learn from the humble salmon

Photo by Markus Spiske on Unsplash

Over the past 5 years, I have interviewed more than 1,000 candidate data scientists for an apparently highly coveted set of jobs at Evo Pricing. In the process I have learned that the media are portraying a fundamental lie about this profession: throwing data at off-the-shelf algorithms is really not the point.

A fundamental rethink would be appropriate, and it is likely overdue.

At its heart, data science is a noble name for a broad set of number crunching activities that were mostly…


Mistakes made by new data scientists are disappointingly similar to those still made by professionals

Over the past year, I’ve had the opportunity to introduce many students to data science. Between teaching an MBA course on Big Data at ESCP and working with students at the Politecnico di Torino to develop an algorithm to forecast trends in fashion as part of a business challenge for CLIK (Connection Lab and Innovation Kitchen), I’ve been able to share what we do with students who may not have otherwise considered its value. Seeing them understand why data science is the future has been gratifying.

In the process, I’ve become much more attuned to the types of mistakes people…


3 analytical approaches to salvage value and prevent waste

Markdowns and waste. Photo by John Cameron on Unsplash

Markdowns are big: what to do with excess inventory?

Some statistics from my recent piece: over $2 trillion of inventory in the United States alone — $2,040 billion — $1.43 of inventory for every $1 in sales. So what to do with that 43% excess inventory, when it will reach end-of-life?

When a product exhausts its likelihood of selling, marking down its price is a reasonable approach to try and clear leftover inventory: salvage value, prevent waste.

There are 3…


3 ways to be more responsive to data volatility

Everyone, myself included, was so excited to be done with 2020. The Covid-19 pandemic made it a challenging year, and the arrival of vaccines gave us all hope that things would be going back to normal.

A few months in, however, we realize that it will take some time for life to return to normal. Italy has just gone back into lockdown again, and vaccine rollouts continue to lag. Things are likely to be unpredictable for some time.

Even then, how will we define normal? People remain unpredictable in the best of times. Trends come and go at an alarming…


This is the appendix to my other piece:

Note: some charting functions in the support file may require using an optional free Excel add-in for best performance.

Detailed step-by-step workings of the examples provided below and also available in the illustrative support file you can freely download.

Let us assume a Normal probability distribution, with mean = 50 and standard deviation = 10. We will have 100 units of product in our warehouse, so to limit the size of the simulation.

In a normal distribution, the mean is the same as the mode and the average, and the curve is…


The 5 secret ingredients to solve for profit, rather than accuracy

Data has a better idea by Franki Chamaki on Unsplash

Prediction errors are everywhere. Over the past 15 years, I met and worked with over 1,000 managers to help them make better decisions every day. First, while at McKinsey as a management consultant; then, at Evo Pricing developing B2B technology products, as a researcher.

Throughout this experience, I felt the fundamental need to predict the future that we humans systematically share: to feel more in control.

Letting go of the urge to narrowly forecast can, however, yield extraordinary results!

How policy prototyping encourages responsible growth

Open Loop Logo

I’m proud to officially share with you today that Evo is an Open Loop participating company.

What does that mean?

Over the final quarter of 2020, Evo was a part of a team of leading AI companies in Europe brought together by Facebook that dedicated itself to developing a data-driven framework to manage AI risk while encouraging innovation and growth. This project allowed us to assess the risks in our own AI applications more deliberately and then work together to create and test an AI risk assessment framework.

If your eyes are glazing over just thinking about AI policy, you’re…


Unexpected skills you must hone to get hired

My company Evo is expanding, which means we’ve been through a few hiring cycles in recent months, something that will continue throughout 2021. We are looking for data scientists that can hit the ground running and quickly integrate into the team.

And yet, we continuously struggle to find the right people. It’s not that the technical skills aren’t out there. We see hundreds of applications with years of advanced math, statistical modelling experience, coding skills, and comfort with Python libraries like Pandas and Numpy. Unfortunately, many applicants fail to highlight the non-technical skills critical to success as a data scientist.

Santa has magic. Is AI our own enchanted solution?

It’s the holiday season, and while festivities may be muted publicly, I’ve still been enjoying lighting the tree, drinking mulled wine, and celebrating with loved ones at home.

As Christmas draws near, it’s impossible not to think of Santa — and as the CEO of an AI company that optimizes supply chain, it’s impossible to ignore his looming logistical challenge. Delivering billions of packages around the entire world in one night? That kind of task would challenge even the most sophisticated AI.

This time of year, a lot of AI companies come out with articles explaining how Santa has used…


Data science trends in retail for the post-Covid world

Image by icondigital from Pixabay

2020 was a difficult year for every business. The coronavirus changed every aspect of our operations. One of the biggest trends in data science caused by the Covid-19 pandemic was an acceleration of the integration of data scientists and data-driven analysis into greater company operations. Data was vital to survive and thrive in the chaos caused by Covid.

This trend was even more pronounced in the retail sector. As one of the hardest-hit sectors this year, retail turned to data science for solutions.

Because of the increasing importance of data science — or business science as I think it’s more…
