Recently, a Dutch man, Tim Hansen, was fined up to 380 euros (about $400) for being mistaken by an AI camera for using a mobile phone while driving. However, Tim insisted that he was just scratching his head and not using the phone, believing that something was wrong with the system.
It is reported that in November last year, Tim received a ticket accusing him of using a mobile phone while driving a month ago. He was shocked because he remembered not using his phone while driving that day. In order to find out the truth, he decided to look at the evidence provided by the judicial collection agency.
Surprisingly, **shows that Tim seems to be playing**. But upon closer inspection, it turned out that he was not really holding the phone. It turned out that he was just scratching his head, and the camera misinterpreted the movement of his hand as holding the phone. Even more surprisingly, the person responsible for reviewing** and confirming the fine did not find this "miscalculation" either.
As an expert in the IT industry, Tim knows how the camera system used (Monocam) works. He used his expertise to explain why the miscalculation occurred. He stated that a perfect model can only be true positives and real negatives, but 100% correctness is rare. As a result, false positives also occur from time to time.
Tim also points out that systems like MonoCam must be trained on a large set of images, which are divided into a training set, a validation set, and a test set. The training set is used to teach the algorithm to recognize objects and attributes; The validation set is used to optimize the hyperparameters of the algorithm; The test set is used to evaluate the actual operation of the system. However, there may be bias or inadequacy in the training dataset, leading to mispositives in some cases.
To improve this, Tim suggests adding more empty-handed ** to the training dataset to improve the accuracy of the algorithm. At the same time, he also called for the introduction of artificial filtering to minimize the number of false positives.
At the moment, the Dutch driver has already disputed the fine and expects a positive outcome. However, he had to wait up to 26 weeks to get an official verdict. The matter has attracted widespread attention in places such as the Netherlands and neighboring Belgium, with some agencies calling for the installation of cameras capable of detecting the use of mobile phones while driving. But Tim's story reminds us that the reliability of these cameras is far from 100%. Therefore, while promoting the use of these cameras, we also need to pay attention to their potential problems and challenges.
