Well-posed problems

Jacques Hadamard (1865-1963) was a leading light of French mathematics. He defined the term “well-posed problem”: a problem that has a unique solution that changes continuously (without leaps) with the initial conditions. Typical compliance problems (name matching, transaction monitoring, wallet screening) do not fulfill these conditions, and are known as “ill-posed problems.”

Ill-posed problems are typically the subject of machine learning methods and artificial intelligence, including statistical learning. These methods do not aim to find the perfect solution; rather, they aim to find the best possible solution and/or the solution with the least errors. As John W. Tukey (1962) aptly said: “Far better an approximate answer to the right question, which is often vague, than an exact answer to the wrong question, which can always be made precise.”

Complete Revision of the Federal Data Protection Act

The complete revision's draft of the Federal Data Protection Act is currently in political consultation. Data Protection is to be increased by giving people more control over their private data as well as reinforcing transparancy regarding the handling of confidential data.
