We’re used by now to celebrity chefs, those hard-working,
talented people who inhabit kitchens and TV cooking and reality shows, and turn
out their own cookbooks. Have you heard
of Chef Watson?
Maybe not, but he’s a celebrity chef anyway, and of a
different sort, because Chef Watson is … a computer.
Watson, IBM’s human-beating technology, first appeared on a
Jeopardy show in 2011, handily beating the human champions, in a quiz show that
uses quintessentially human qualities – such as understanding arcane clues in
natural, as opposed to, computer language. Being a computer, Watson also ingests vast
amounts of data, and it doesn’t forget, doesn’t get fatigued, get confused or
have human frailties such as prejudices and preferences. What’s more, Watson operates at blinding
speeds.
Now Watson, which learns on the go and improves over time,
has come to the kitchen.
Watson is very ‘smart’, but completely child-like, having no
knowledge of its own. Everything must be taught by humans, but if Watson is
trained in a particular subject, that it learns and adapts rapidly. Like a baby, Watson needs to be fed, but
instead of food, what it eats is data - lots and lots of it.
In this case, Chef Watson was taught about cooking, and not
just cooking, but also ingredients, the chemical composition of ingredients,
what tastes good to humans, what doesn’t, the differences between different
types of cuisines, the differences between a roast and a soup, a soup and a
stew, between different cuisine types such as Japanese and Korean, for
example. It knows a lot more about food
than any human can – after all, how many of us can remember the hundreds and
hundreds of chemicals that go into any food item such as a tomato, or chili?
As a base, Watson was also fed 9000 recipes from Bon
Appetit. The interesting thing about
Watson is that it only knows what it knows.
If there are no recipes which use, say, sea cucumber, Watson will have
no idea what to do with a sea cucumber. For a sample of Chef Watson’s adventures,

Why would anyone teach a computer about food when there are
already millions of people who obsess about it on a regular basis – what to eat
for lunch, for example? The idea is for
Watson to learn what it does, and to develop recipes never seen or tried
before. In that context, Watson has some
advantages.
Unlike humans, Watson doesn’t have knee-jerk reactions to
what will work and what won’t. It also
understands how different flavours work together at a chemical level, and what
combinations of chemicals tend to work well and what doesn’t.
And indeed, even professional chefs have been surprised by
some of Watson’s unusual food combinations.
Although it comes up with ingredients, it needs humans to decide on the
proportions and to do the actual cooking and presentation.
In a further leap of Watson’s culinary adventures, IBM also
partnered with the Institute of Culinary Education to come up with a cookbook. Featuring
65 original recipes, the cookbook “Cognitive Cooking with Chef Watson: Recipes
for Innovation from IBM & the Institute of Culinary Education”, is
available for sale.
But you can decide for yourself, because a beta app is
available for use. In the app, you can
tell Chef Watson what ingredients you want to use, what you want to exclude,
and you can also set a slider scale on how adventurous you want the results to
be. Chef Watson can adapt on the fly,
meaning you can tweak the surprise level, or the types of ingredients, as you
go along.
Crucially, how does the food taste? The proof of the pudding is in the eating, so
why not try it out yourself? Just register, for free, at www.ibmchefwatson.com and surprise
yourself. Happy cooking!
