. Weighted rainbow boxes showing the antibiotics available for treating cystitis in adults with risk of complication, and the disadvantages of each drug. The 10 available antibiotic drugs are displayed in columns, and the 6 disadvantages they may present are represented by rectangular red boxes. Each box covers the columns corresponding to the antibiotics having the disadvantage, and antibiotics were ordered so as to limited "holes" in the boxes. Here, a single hole is present (in the "ceftriaxone" column). The height of a box is proportional to the importance of the corresponding disadvantage, allowing the computation of a score for each drug, by visually summing the height of the boxes stacked in the drug's column. Here, lower score means better antibiotics, thus nitrofurantoin is the best treatment. Abstract-In this paper, we propose a technique for translating visually the reasoning of a perceptron. The artificial neuron, or perceptron, is a simplified model of a biological neuron. It can achieve simple reasoning and solve linearly separable problems. Despite its limited reasoning power, it is enough to deal with several real-life problems. The proposed technique is based on rainbow boxes, a technique for overlapping set visualization, which has been applied to the input vectors of the perceptron. We extended this technique, leading to weighted rainbow boxes. It can visualize several input vectors and output values for a single perceptron. We applied this approach to decision support in antibiotherapy, for the determination of the most appropriate antibiotic in urinary infections, by taking into account the properties of each drug (e.g. efficacy, risk of adverse effects, etc). Finally, a user study with 11 physicians showed that most of them found the visualization interesting and easy to read.
In a previous work REF , we introduced the use of weighted rainbow boxes, a typed-set visualization technique, for trans- lating visually the reasoning of a single perceptron.
