10 questions · two minutes

1. Your model scores very well on training data but poorly on new data. What do you do?

2. How do you feel about the mathematics behind machine learning – linear algebra, probability and optimisation?

3. You receive a large, messy dataset with missing values and outliers. How do you approach it?

4. Your project team includes people from several countries, and code reviews and presentations are in English. How do you feel about that?

5. A new research paper presents a deep learning architecture. What do you do?

6. Your model will help decide who gets a loan. What concerns you?

7. How do you choose between a simple model and a complex one?

8. Would you like to work on a research project, for example for your Master’s thesis or a publication?

9. Where can you see yourself after this degree?

10. What motivates you most to pursue a Master’s degree in Data Science?

⇑Definitions and quotes

Data
Data ( DAY-tə, DAT-ə, DAH-tə) is a set of values of qualitative or quantitative variables.
Data Science
Data science is an interdisciplinary field of scientific methods, processes, algorithms and systems to extract knowledge or insights from data in various forms, either structured or unstructured, similar to data mining.
Science
Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Science
We’ve arranged a global civilization in which most critical elements profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.
Sir Ernest Rutherford from The Demon-Haunted World: Science as a Candle in the Dark (1996), 26.
Science
The men in the laboratory... cannot be said to observe the actual objects of their curiosity at all. ...The sense data on which the propositions of modern science rest are, for the most part, little photographic spots and blurs, or inky curved lines on paper. ... What is directly observable is only a sign of the "physical fact"; it requires interpretation to yield scientific propositions.
Susanne Langer, Philosophy in a New Key (1942)
Science
Within the short span of a human life and with man's limited powers of memory, any stock of knowledge worthy of the name is unattainable except by the greatest mental economy. Science itself, therefore, may be regarded as a minimal problem, consisting of the completest possible presentment of facts with the least possible expenditure of thought.
Ernst Mach, The Science of Mechanics: A Critical and Historical Account of Its Development (1893) p. 490, Tr. Thomas J. McCormack.
