More about this list
Here el lote is a batch: el lote de datos, the handful of examples a model sees at once. The word does three other jobs that English hands to different nouns. At an auction it is a lot, el lote número siete. At Christmas it is a hamper, un lote de Navidad, the box of food a company sends round. And across much of Latin America it is a plot of land, un lote urbanizable. What holds them together is the idea of a portion set aside, which is exactly what a batch of data is.
