kandi X-RAY | myra Summary

myra is a Java library typically used in Artificial Intelligence, Machine Learning applications. myra has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. However myra has 42 bugs. You can download it from GitHub, Maven.

MYRA is a collection of Ant Colony Optimization (ACO) algorithms for the data mining classification and regression tasks. It includes popular rule induction and decision tree induction algorithms. The algorithms are ready to be used from the command line or can be easily called from your own Java code. They are implemented using a modular architecture, so they can be easily extended to incorporate different procedures and/or use different parameter values. This repository contains a complete rewrite of the code (by the same author) from the MYRA project hosted at sourceforge. The computational time has been significantly improved — tasks that used to take minutes, now are done in seconds — although it was not possible to maintain backward compatibility. You will find that the overall architecture is very similar, but most of the data structures have changed. While this repository is a fresh start, the versioning is maintained — version 4.x is the new version of the refactored code. If you are interested in the hierarchical multi-label algorithms (3.x versions), check the sourceforge repository. These algorithms will eventually be refactored into this repository.

Basic R: move y-Axis for barplot

Asked 2021-Jan-27 at 18:56

is there a way to move the y-Axis to the right, so that the gap between the y-Axis and the first bar is 0?

So far i've tried the axis() command to make a new y-Axis. But i always get the same one shown above.

Here is a sample of the dataset:

Reduce left outer join in SQL query

Asked 2020-Mar-22 at 11:08

Updated with sqlfilld SQLfiddle

I have an Oracle query where I need to reduce the number of left outer join to perform efficiently. The current query runs for more than 2 hours and I want to reduce its complexity by reducing the number of join operations.

Without the joins, the query runs in 15 minutes. Hence I want to rewrite the logic. Is there any efficient way to do that?

When checking whether data exists in a table we use EXISTS or IN, not JOIN (SELECT DISTINCT ...). Hence this is the query I'd probably come up with:
