the difference of predict result between using xgboost-predictor and using python

Hi,
i train xgboost model with python and save it as 001.model,for test, i use this 001.model to predict one sample in python, get 0.223，but get 0.0604 with using xgboost-predictor，same model,same sample,but different predicted result,and i test another sample, still get different result,only the same thing is using python to predict can get larger score. i have no idea to deal with this problem.note that,my input is a hashmap,like this:{33 : 1.0,34 : 1.0,125 : 0.04261,185 : 0.01504}

prediction for rank task

i want make prediction for rank task. the objective i used in xgboost is rank:pairwise.
but i found prediction is not correct compared with xgboost predict function.
i use the code in the main page. is something i missed? should i set PredictorConfiguration specifically for rank task?

wish your help, thanks ahead!

xgboost-predictor-spark build error

I need to resolve some error to get my employer's clearance to contribute a new feature. I'm trying to build the dependencies with gradle:
./gradlew xgboost-predictor-spark:dependencies

But I get the error...
Project 'xgboost-predictor-spark' is ambiguous in root project 'xgboost-predictor-java'. Candidates are: 'xgboost-predictor-spark_2.10', 'xgboost-predictor-spark_2.11'.

I don't know enough about the Scala Cross Build plugin from LinkedIn to fix this. The variable is set in:
buildSrc/src/main/groovy/com/linkedin/photon/build/plugins/ScalaCrossBuildPlugin.groovy: def scalaSuffix = getScalaVersionSuffix(scalaVersion)
buildSrc/src/main/groovy/com/linkedin/photon/build/plugins/ScalaCrossBuildPlugin.groovy: ext.scalaSuffix = scalaSuffix

Push to maven central

Hey,

It would be great to get this library onto maven central. This would allow other projects that depend on yours to push to maven central as well. Right now, I have to include your jar file locally in my git repo instead of being able to add it as a dependency.

Thank you for this great project!

[Question] Open to PRs ?

Hi @komiya-atsushi,

This is in relation to this tolerance bug komiya-atsushi/xgboost-predictor-java#21 that affects correctness of results on complex models. We have since fixed it in our fork at Yelp and achieved complete parity of results with xgboost4j.

We're now wondering if you would be open to PRs so that we can contribute this upstream. Just asking before we do the work and open the PR :)

any plans for supporting pred_contribs?

Currently XGBoost Python API support pred_contribs in Booster.predict. This option is useful for debugging some certain prediction cases because we can get contributions of each feature and find some explanation for the prediction result.

The API Doc http://xgboost.readthedocs.io/en/latest/python/python_api.html#xgboost.Booster.predict
Related commit dmlc/xgboost@6bd1869
Inspired by http://blog.datadive.net/interpreting-random-forests/

I'm wondering is there any plans for support this feature in this project? Thanks sincerely！

Too long string

when i use XGBoostPredictor load one model to do a test, one exception happenned. How can i sovle it?

Predictor predictor = new Predictor(
                new `java.io.FileInputStream("./model/ransom.pickle"));

Exception in thread "main" java.io.IOException: Too long string: 7887331693998180980

at biz.k11i.xgboost.Predictor.(Predictor.java:26)
at HowToUseXgboostPredictor.main(HowToUseXgboostPredictor.java:16)

does this package support multithreading?

I know that the XGBoost package itself supports multithreading of the prediction task. Does this predictor implementation also support multithreading? If not, how could I go about adding it?

Upgrade gradle support

I have a functioning contribution that I'm just about ready to push. I just need some help upgrading gradle as I have to run the contribution by the open-source overlords at my employer. Can someone help me upgrade gradle support to the latest stable version?

speed for a single record

Did you know about dmlc/xgboost#1849 (comment)

Apparently xgboost4j is quicker for batch predictions in the current version than this library.
Do you have a test which compares predicting a single new value and not 200k values? As described in the linked xgboost issue xgboost4j,s api is only supporting batch mode. What about your library?

I have tested on a dataset (containing 200,000 data) on spark. The xgboost4j-spark cost 1775736 milliseconds containing implicit data transformations. xgboost-predictor-java cost 4620104 milliseconds containing data transformations and 2907550 milliseconds without transformations. I think xgboost4j's prediction on a batch is faster and I will keep using xgboost4j.

Training Data of xlm-roberta-large-finetuned-conll03-* models

Hi, I'm curious about the training data of xlm-r models finetuned on conll ner datasets (e.g. xlm-roberta-large-finetuned-conll03-german, xlm-roberta-large-finetuned-conll03-english), are the models trained on train+dev sets?

xgboost model question

hi，i am get a model from xgboost with python, and i use the model with your method,
but i get the same score for every in put data, if you method can use the model from xgboost with python ?

Could you compare performance against treelite and pmml?

Treelite can convert xgboost model into pure C code. https://github.com/dmlc/treelite

And pmml is also widely used. https://github.com/jpmml

Usage with given features matrices

Hi,

Your implementation looks promising, but I am not sure how to use it.
Suppose we have age, gender and height(in cm) and we need to predict the weight (in kg) of people.

So we have for training set the following csv:
age,gender,height,weight
18,m,180,80
40,m,175,85
25,f,165,50

and we load it into a feature matrix:

float[][] trainFeatures =  new float[][] {
 { 18, 1, 180 },
 { 40, 1, 175 },
 { 25, 0, 165 }
}

and into a vector of target values:
float[] targets = new float[] { 80, 85, 50 }

and we also have a test set for which we need to predict the target values:
22,m,175
30,f,160

which we load into a feature matrix:

float[][] testFeatures =  new float[][] {
 { 22, 1, 175 },
 { 30, 0, 160 }
}

Can you please give an example of how the xgboost-predictor can be applied to such data to train on the first set and predict on the second set?

Thank you

Doron

predictor-spark work with model built from scala libs

hi Komiya,
This is a very interesting project you've built!
I have one question: is it possible to load model built from "ml.dmlc.xgboost4j.scala.{XGBoost, DMatrix}" libraries with the predictor-spark package?

I was able to do this without error but the model looks strange to me:
scala> model.numFeatures
res15: Int = -1

and the prediction results are completely wrong.

Thanks.

PredictSingle Error for binary classifier

I am getting below error when trying to predict for single example on binary classifier model.
java.lang.IllegalStateException: Can't invoke predictSingle() because this model outputs multiple values: 0
Below is code :

Predictor predictor = new Predictor(
new java.io.FileInputStream("path-to-model-file"));

// Create feature vector from sparse representation by map
FVec fVecSparse = FVec.Transformer.fromMap(
new java.util.HashMap<Integer, Double>() {{
put(49722683, 0.);
put(123455, 1.);
put(50000001, 1.3979400086720377);

                }});        

double pred = predictor.predictSingle(fVecSparse);

When creating feature vector from dense representation by array, do you use the first element as the first feature or the label?

Hi,

When creating feature vector from dense representation by array, do you use the first element in the array for the first feature and the second for the second and so on or is the first element for the label as a placeholder?

Thanks,

Does 0.2.1-ver support 0.82-xgboost-py trained model?

Need I to update ver to 0.30?
What's the differences between theses versions?

Thanks ^ ^

Parity between c++ xgboost and xgboost-predictor-java

Hi -

Have you done any parity tests between the scored output of the c++ models and the java models?

Asking because I'm seeing large differences (greater than 1) when using double precision values when doing regression.

Using these training parameters:

    "eta" -> 0.3,
    "max_depth" -> 2,
    "objective" -> "reg:linear",
    "early_stopping_rounds" ->2,
    "num_round" -> 15,
    "nworkers" -> 2

When I cast the Doubles in the FVec to a Float first, I then see the results are much closer, to within a .0001 tolerance.
