dataset

问题 I am currently doing performance testing with JMeter for an application in my company. The application requires a login and I have to use multiple users. The way this is usually done in JMeter seems to be via CSV dataset, however I have access to the database and can read all the credentials from there directly. Since it is a test environment, all users have the same password, so I can hardcode it, but I need the list of usernames. JMeter can already do JDBC requests, but I was wondering if

问题 I am looking for datasets that can be used for implementing recommendation system usecase of Apache Mahout. I know of only MovieLens Data Sets from GroupLens Research group. Anyone knows any other datasets that can be used for recommendation system implementation? I am particularly interested in item-based data sets though other datasets are most welcome. 回答1: this is Sebastian from Mahout. There is a dataset from a czech dating website available that might be of interest to you: http://www

问题 I'm trying to obtain a data set from a PostgreSQL 9.0 function and I'm not able to with stored procedures. I'm new to Postgres this week so let me explain my terms: In pgAdmin III I can enter the command: SELECT * FROM member; And receive the following Data Output: memberid membername 1 Bill Smith 2 Joe Smith I tried creating MANY functions (tables / SETOF / etc) pretty much like: CREATE OR REPLACE FUNCTION get_all_members() RETURNS SET OF member AS 'select * from member;' When I run them in

问题 I have been facing a strange problem while returning dataset through WCF service (WSHttpBinding). I'm explaining the senario below: I have a Businesslayer, inside is a folder 'Demo', which contains a class file demo.cs, which carries the variable for a particular table. Next, i have a Datalayer, inside is a folder 'Demo', also contains a class file demo.cs, which contains all the database related functions and methods. Next, I have created a WCF service, which contains a interface (Idemo.cs),

问题 Anyone have dataset download link for text summarization like DUC 2007 or TREC? Please, help me. 回答1: You can use http://archive.ics.uci.edu/ml/datasets/Legal+Case+Reports for extraction based text summarization approach. It contains catchPhrase, which can be act as selected sentence for training. But catchphrase may not be as much appropriate. 回答2: You can access DUC dataset after completing some organization and individual agreements ..kindly refer http://www-nlpir.nist.gov/projects/duc

问题 I am working on a web application that is consuming a Dataset returned by a web service. As the application is running I store that Dataset as a session variable to be used over and over again as the user navigates to the different pages that will edit the tables within the dataset. The idea was the user will only have to wait for the data once when the application loads then the application would use the session variable until the user saves the changes they made, when that happens it would

问题 Why am I getting this error in my chart? (Chart Image) I am using this expression in the chart: Series: =Sum(Fields!Mins_Att.Value)/Sum(Fields!Mins_Poss.Value) Series 1: =Sum(Fields!Mins_Att.Value, "Chart2_CategoryGroup2")/Sum(Fields!Mins_Poss.Value, "Chart2_CategoryGroup2") and I am getting this error: The Y expression for the Chart has a scope parameter that is not valid for an aggregate function. The scope parameter must be set to a string constant that is equal the name of group, data

问题 I am currently working on project whose main task is to read data stored in SQL database and to display them in user-friendly form. Programming language used is C++. I am working in Borland C++ Builder 6 environment. But I think question posed in title is independent from programming language or libraries. When reading data from db i am quite frequently meeting with these terms in class names without knowing exactly what they represent. I understand that they behave as interface to data

问题 I have a procedurally generated (infinite) data source and am trying to use this as input to the high-level Tensorflow Estimator to train a image-based 3D object detector. I set up the Dataset just as in the Tensorflor Estimator Quickstart, and my dataset_input_fn returns a tuple of features and labels Tensor 's, just as the Estimator.train function specifies, and how this tutorial shows, but I am getting an error when trying to call the train function: TypeError: 'Tensor' object is not

问题 Simple task at hand: run training for N epochs performing calculating exact validation accuracy after each epoch. Epoch size can be either equal to full training set or some predefined number of iterations. During validation every validation set input has to be evaluated exactly once. What would be the best way to mix together one_shot_iterators, initializable iterator and/or handle for that task? Here is scaffolding of how i see it should work: def build_training_dataset(): pass def build
