Teams from all over the world competed to build the best video recommender system for Netflix. As the competition progressed, teams found that they obtained the best results by combining their learners with other teams’, and merged into larger and larger teams. The winner and runner up were both…

Pedro Domingos is Professor at University of Washington. He is a researcher in machine learning and known for markov logic network enabling uncertain inference. 2Biography Domingos received an undergraduate degree and M.S. from Instituto Superior Técnico (IST). And then at University of California, Irvine, he received an M.S. and Ph.D. After spending two years as an assistant professor at IST, he joined University of Washington in 1999 and now is a professor. 2Research 3Markov logic network 2Awards and honors 2014. ACM SIGKDD Innovation Award. for his foundational research in data stream analysis, cost-sensitive classification, adversarial learning, and Markov logic networks, as well as applications in viral marketing and information integration. 2010.

Learners can be divided into two major types: those whose representation has a fixed size, like linear classifiers, and those whose representation can grow with the data, like decision trees.
As a rule of thumb, a dumb algorithm with lots and lots of data beats a clever one with modest amounts of it.
Every learner must embody some knowledge or assumptions beyond the data it’s given in order to generalize beyond it.
Everything is connected, but not directly.
Learning a Naïve Bayes classifier is just a matter of counting how many times each attribute co-occurs with each class
You don’t need to understand the details of the message; it’s enough to get the gist of it by seeing which words it contains.
Someday there’ll be a robot in every house, doing the dishes, making the beds, even looking after the children while the parents work.
Machine learning will bring about not just a new era of civilization, but a new stage in the evolution of life on Earth.
Machine learning takes many different forms and goes by many different names: pattern recognition, statistical modeling, data mining, knowledge discovery, predictive analytics, data science, adaptive systems, self-organizing systems, and more.
In general, the more rules and facts we start out with, the more opportunities we have to induce new rules using ‘inverse deduction.’ And the more rules we induce, the more rules we can induce. It’s a virtuous circle of knowledge creation, limited only by overfitting risk and computational cost.
If you try to come up with a set of rules that makes an exception, you’ll probably wind up with a worse answer than if you’d just ignored it. Learning a set of rules that gets [hyper-contextual instances] right is actually counterproductive: you’re better off ‘misclassifying’ it.
It’s even been said that data mining means torturing the data until it confesses.
Overfitting happens when you have too many hypotheses and not enough data to tell them apart.
In ordinary life, bias is a pejorative word: preconceived notions are bad. But in machine learning, preconceived notions are indispensable.
Every algorithm, no matter how complex, can be reduced to just these three operations: AND, OR, and NOT.
