kandi X-RAY | cubist Summary
Implementation of Bottom-Up Cubing Algorithm for Iceberg Cubes, Beyer et al, SIGMOD 99. Assumes Measure is monotonically increasing i.e. M(A union B) >= M(A). Successively sort and partition data by columns, aborting sort if partition’s aggregate doesn’t meet threshold, since it’s sub-partitions will apriori not meet threshold either.

QUESTION
I could and should have made a simpler reprex, but this is really straight out of my work. After training a C5.0 model in the Tidymodels framwork, how do I "see" the rules that the model generated? I tried to replicate what is illustrated here
https://www.tidyverse.org/blog/2020/05/rules-0-0-1/
but I did not go very far (but I am sure the solution must be a one-liner).
Many thanks!
...ANSWER
Answered 2020-Dec-10 at 23:59The current solution that tidymodels offers to get the rules out is not quite ideal, admittedly. I believe currently the best way to get out the rules in the model is to pull out the underlying fit object, which is several layers deep inside of the workflow and then call summary() on it. You want to do: summary(fit_model$fit$fit$fit).
QUESTION
I am currently trying to learn to use Google Kubernetes Engine and Google Cloud SQL. In doing so i have created a AspnetCore 3.1 Web Api project in my visual studio 2019, to use as a training project.
At the moments i am currently able to do the following.
- Deploy the Web Api to GKE, using Google Cloud Tools for Visual Studio
- Connect to Cloud SQL from own PC, using SSMS and Cloud SQL Proxy
What i want to be able to do is as follows.
- Deploy the Web Api to GKE, using Google Cloud Tools for Visual Studio, with a sidecar, containing Cloud SQL Proxy
From my understanding of Cloud SQL, it is best to always access it via the proxy, as it is more secure, which is why i want the sidecar. To get the proxy to work, i however need the credential file saved in my secrets in GKE. I also have some database related variables that need to be passed in as environment variables, again from secrets in GKE.
At the moment in my solution, beside my api project file, i have a Dockerfile, that looks as follows.
...ANSWER
Answered 2020-Nov-27 at 14:20I managed to get it to work by creating my own class in my project, that given the path to the proxy file would run it with the required arguments, which i also feed to it via my class. To get the proxy file together with my own code i used the following Dockerfile to build my images.
QUESTION
I am trying to auto scale java spring framework kafka consumer with docker-compose with --scale flag and forwarding ports in docker-compose.yaml like "8070-8072:8070". So when i trigger endpoint for publishing messages, it does well. But in consumer side just 1 consumer consumes all messages. I have 3 consumer with same group-id and different client-id. What i want is a distributed messaging. I read some paper about partitioning and i looked up my logs. It seems there just 1 partition. Is it the reason? How can i achieve this? I'll add the log, consumer config, publisher config and docker-compose file. Firstly the log. It seems just 3 of 1 have partition.
command:
...ANSWER
Answered 2020-Jul-10 at 17:02It seems there just 1 partition. Is it the reason?
Yes, if there is only one partition, only one consumer (from the consumer group) can consume it and other consumers (from the same group) will be idle even they are started.
It seems just 3 of 1 have partition
From your image, I can see that the topic_trial-0. So it is the topic_trial's 1st partition.
Increase the no. of partitions, to 3 for example and start three consumers with same group.id and the load should get distributed (one partition for each).
QUESTION
I'm trying to create a table with React that will receive JSON data eventually (via HTTP request). I am currently storing the data in the state of my first component, and then rendering the table in my second component.
I would like each row in my table to contain an image of an album cover, followed by text data about the track, artist, and album title. For this post, I will include one row of my data so that you may see how it is stored in state.
I am currently unable to render an image stored as a string in state. What could I changed about my getRowsData() function in order to make this work? Or maybe I need to change how I am calling my image string? Any help or advice would be greatly appreciated.
The state (with image string as a .jpeg file) is found here:

QUESTION
I have a data set like the following
...ANSWER
Answered 2019-Dec-06 at 15:03I think the answer you are looking for is actually quite simple. You can use the skip argument to trainControl() to skip the desired number of observations after each train/test set. In this way, you only predict each group-period once, the same period is never split between the training group and testing group, and there is no information leakage.
Using the example you provided, if you set skip = 6 and horizon = 6 (the number of groups), and initialWindow = 115, then the first test set will include all groups for period 116, the next test set will include all groups for period 117, and so on.

Answered 2018-Oct-31 at 08:40You should first take the search query url in start_urls and from the response of start_url, extract all the urls and send request to each one of them. After that extract the pdf link and save it to your local storage.

QUESTION
The below code works correctly, but it only returns the last value of the 16 variables in list methodlist. As you can see below, I would like to return 6 variables (z in seq(1:6)) for each variable in methodlist. So I want to return a 6x16 matrix, not a 1x16 matrix as present. What does the code look like to append a list of 6 rows for each variable in methodlist.
ANSWER
Answered 2018-Oct-07 at 22:23Your current loop structure will make it so that output[i] captures the final output of each inner loop. All 6 runs of the inner z loop are writing into the same element of output, so the first 5 runs are successively overwritten. Instead, output should become a list of lists (fit should be changed in the same way to match). I can't run your code myself, but as far as I can tell there are only a few small changes needed, which I've marked with comments:

Install cubist
You can use cubist like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the cubist component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
