kandi X-RAY | hipster Summary

hipster is a Java library typically used in Tutorial, Learning, Example Codes applications. hipster has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub, Maven.

The aim of Hipster4j is to provide an easy to use yet powerful and flexible type-safe Java library for heuristic search. Hipster relies on a flexible model with generic operators that allow you to reuse and change the behavior of the algorithms very easily. Algorithms are also implemented in an iterative way, avoiding recursion. This has many benefits: full control over the search, access to the internals at runtime or a better and clear scale-out for large search spaces using the heap memory. You can use Hipster4j to solve from simple graph search problems to more advanced state-space search problems where the state space is complex and weights are not just double values but custom defined costs.

Splitting a dictionary like object into new columns

Asked 2022-Feb-05 at 06:55

I have this dataframe. How I got this dataframe was due to using .to_dict(). It manages to split the initial dictionary into individual columns on key:value pairs. However some keys has a dictionary like value. For instance like the Ambience column here.

I believe the initial dictionary is something like this

QUESTION

Conditionally assign values from one dataframe to another [R]

Asked 2022-Feb-05 at 00:36

I am learning R. I know how to join dataframes based on various criteria and using various methods - all of that if they have something in common (e.g. column). But what if they do not?

I have a two example dataframes: df_data and df_categories (code provided below). I would like to modify df_data by adding new columns based on the values in df_categories. The dataframes do not share a common column.

...

ANSWER

Answered 2022-Feb-05 at 00:36

I think you can try this approach with merging the two data.frames. Since they have no columns in common, you can create columns to merge on, based on your groups and position within each group.

First, use rleid to provide unique id's for each group in both data.frames. Then, use rowid to enumerate rows within each group. Then merge.

JSON / struct column type in AWS GLUE + AWS Athena / Hive?

ANSWER

Answered 2022-Jan-03 at 05:35

Will try to answer all of your questions.
Can this file be processed with AWS Glue to be input for AWS Athena / Hive (which is used internally in Athena)?
Should be. if you structure hive table properly, any csv file can be uploaded there.

how can I specify the data type for JSON columns?
in hive you can store as string. Looking at your json structure, you can easily access elements using expression like this - get_json_object(json_col_str,'$.BusinessParking.garage').

Do I have to do this by hand?
I guess so unless you have some auto DDL creation utility. You can put sample rows in xl and find out the table structure easily.

Are the JSONs written OK, or should they be reformatted?
From the example you gave, i checked last row and json object seems fine to me. I also checked using https://jsonformatter.curiousconcept.com/ which validates and formats it in a pretty format. You can use it in case of any discrepancies.

ANSWER

Answered 2021-Dec-20 at 10:52

v-on:click="selectedPost = post" is the culprit; selectedPost is a prop here and you cannot assign to a prop.

There are two different solutions depending on what you want:

Make selectedPost a local data property instead of a prop. You can then modify selectedPost but since it is no longer a prop, you cannot accept selectedPost from the parent anymore (but you're not really doing that anyway).
