(A) Schematic of automatic toxicity readout. (B) Class vs. prediction box plot. (C) Fluorescent images of spheroids treated with different cisplatin concentrations c and corresponding cell death rates Ψ: Spheroids with low death rates (I) show obviously different appearances. Spheroids with intermediate (II) and high (III) death rates show similar appearances. (D and E) Confusion matrices when using the neural network as a classifier. The 2-class problem delivered a balanced accuracy: 98.2%. The 3-class problem delivered an accuracy of 78.7%.
