title: Accidentally Reinforcing Model Predictions in iNaturalist with Seek
--- ---
I [previously wrote](/blog/identifying-plants-with-inaturalist/) about using Seek to identify organisms and then uploading them separately to iNaturalist. Though after some thought I believe that by only uploading photos that Seek has blessed as knowing, I may be reinforcing peculiar features of the dataset and hence the model.

For the image itself, one recommendation I have is the following. Take the image that Seek recommends for the classification, and then take one or two different angles of the same organism. Within iNaturalist, you can upload multiple photos for a single organism. For the image itself, one recommendation I have is the following.

In functional programming, we often look at a list in terms of its head (first-element) and tail (rest-of-list). This allows us to define operations on a list recursively. For example, how do we sum a list of integers such as `[1, 2, 3, 4]`? In functional programming, we often look at a list in terms of its head (first-element) and tail (rest-of-list).

However if we're sticking to a recursive approach, one way we can reduce redundancies is to use memoization. The idea here is that we save prior computations in some data structure and refer to them if requested.
