14.15 Fotoherkenning Paddenstoelen: een vloek of een zegen?

We're currently training a new model based on an export in September that had ~18 million images of 35k+ taxa. It's running with the same setup that we've used on previous models, but with a lot more data, so it will probably take ~210 days and be done some time next Spring. We're simultaneously experimenting with an updated system (TensorFlow 2, Xception vs Inception) that seems to be much faster, e.g. it seems like it might do the same job in 40-60 days, so if it seems like the new system performs about the same as the old one in terms of accuracy, inference speed, etc., we might just switch over to that and have a new model deployed in January or February 2021.

FWIW, COVID has kind of put a hitch in our goal of training 2 models a year. We actually ordered some new hardware right before our local shelter in place orders were issued, and we didn't feel the benefit of the new hardware outweighed the COVID risk of spending extended time inside at the office to assemble everything and get it running. Uncertainty about when it would be safe to do so was part of why we didn't start training a new model in the spring (that and the general insanity of the pandemic), but eventually we realized things weren't likely to get much better any time soon so we just started a new training job on the old system.

The Academy is actually open to the public again now
