Interview Prompt
The ML team is looking for models that punch above their weight: high accuracy relative to how recently they were trained, using the training timestamp's epoch value as the denominator. Which single model has the highest accuracy-to-training-time ratio? Exclude models with no accuracy score and show the model name, accuracy, training timestamp, and the ratio.
Summary
Fast to train. Accurate too. Which model?
