kandi X-RAY | hoku Summary

hoku is a C++ library typically used in Artificial Intelligence, Machine Learning, Deep Learning, Example Codes applications. hoku has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Ancient mariners could look up the night sky, point out what stars they were looking at, and navigate across the globe with precision. Star identification algorithm refers to a computational approach to pointing out which stars are in the sky. Given an image of the sky, star identification is matching the bright spots in an image, to stars in an astronomical catalog. The device that performs these computations is the star tracker, much like the navigators on the ship. Lost-in-space refers to an additional constraint on the problem: the absence of knowing where we took the picture and how we pointed the camera. This repository holds research toward the analysis of various lost-in-space star identification procedures for spacecraft. This includes a study of feature uniqueness, permutation order, candidate reduction, and identification under the introduction of various noise. The process of identifying blobs in an image, constructing the image coordinate system, and efficiently querying static databases is not addressed here, but there does exist some rudimentary programs to execute the attitude determination process end-to-end.

            Extracting words based on a $ and unnesting the data
            Asked 2020-May-06 at 19:19

            I'm not 100% sure what you mean with the first part of your question. Assuming you want to extract all words after the word earnings and before $, this should do what you want. It uses a 'positive lookahead' and allows for any number of words until it finds the first dollar sign (hence the *?).

            Rather than unnesting, I loop over the extractedWords column using purrr::map_chr, which returns a character vector, which makes further unnesting unneccessary.

            I have some text data and I want to try and extract the numbers and text based on a condition. That is, extract the data containing all of the dollar $ values which are to the left and right of the Word "to" and "and".

            If we need to extract the 'to/and' along with the dollar amount, one option is str_extract_all from stringr where we specify the pattern to match as $ followed by one or more digits including the ., followed by zero or more spaces (\\s*), then either the 'to' or 'and', followed by zero or more spaces and the dollar digits
