A. Chess B. Shogi C. Go D. Tetris
6. What did a neural network trained to detect malignant skin lesions in biopsy images mistakenly use for diagnosis?
A. Artefacts in the image B. The presence of a ruler C. The colour of the slide D. The size of the lesion
7. What year did Sir Godfrey Hounsfield invent the first CT scanner?
A. 1965 B. 1967 C. 1971 D. 1973
8. In 1967 the US computer scientist Marvin Minsky – one of the founders of AI – famously said that “the problem of creating ‘artificial intelligence’ will substantially be solved” by when?
A. The end of the 1970s B. Within a generation C. By 2000 D. Before the end of the 21st century.
