Dear Prudence is Slate's advice column. For this edition, Alicia Montgomery, Slate's vice president of audio, will be filling in as Prudie. My friend Kari and I have been close since we were college roommates (we are now just about 40). Kari has been with her long-distance girlfriend Lora for the last four years, and recently Lora has been talking about moving to Kari and my town in order to better facilitate having a baby. The road for them is going to be long, given the mechanics and their ages, but they have all systems go from their doctors. The problem is that I know Kari is not 100 percent committed to Lora; she says she's not sure she's the one and has built (but not, to my knowledge, deployed) dating profiles on multiple sites and expresses jealousy to me quite often about my adventurous dating life.

A Vietnamese woman who lives in Miyagi Prefecture sent a message to the "letters from readers" section of the Kahoku Shimpo expressing a grievance. The letter explained that when she informed the Japanese-language school where she had been studying that she had to cancel her enrollment because of financial hardship stemming from the pandemic, she was about to pay a cancellation fee of ¥3 million, after being pressured by the school to do so. The school said that it asks for such a fee to discourage students from quitting the school and switching to a work visa, but experts say the approach takes advantage of students' weak position and is a violation of their human rights. In November 2020, the woman, who is in her 30s, obtained a student visa, came to Japan and entered the Japanese-language school in Sendai's Aoba Ward. She planned to study Japanese for two years with a goal of becoming a nursing care worker in Japan.

There is a problem with artificial intelligence and that is because it is artificial. No amount of coding can replace human intelligence and more than that, intuition; the ability to see the bigger picture and to make the correct assumptions and decisions from a myriad of factors. Hence the major concerns that the overhyped driverless automobile will never really become a reality. Let us look at a much simpler example, something that happened to me today and that has left me totally frustrated, with the amount of time wasted and the sheer incompetence of the technologists and the lack of understanding of business. A close relative indicated that a certain Apple accessory would be a suitable gift for a coming birthday and given that the closest Apple Store to where I live is some 50 km distant (not to mention all the restrictions relative to the pandemic), I sat myself down to order the item online.

Data annotation is the task of labeling data, which could be in any form such as text, audio, images, or video. In this article, we'll explore the different types and uses for data annotation in machine learning. Data scientists need to use clean, annotated data to train machine learning models. Data annotation is an indispensable stage of data preprocessing in supervised learning. Machine learning models learn to recognize recurring patterns in the annotated data.
