Is There A Way To Get The Node Descrption In The Same Query Where You Get The Prediction?
Feb 8, 2008
I am doing this right now this way:
1) I do the DMX prediction query where I get the PredictNodeId(predict_var), my query is like this:
SELECT PredictNodeId(predict_var), model_1.predict_var, t.var_1, t.var_2 FROM model_1 PREDICTION JOIN OPENQUERY([DATA_SOURCE_1], 'SELECT var_1, var_2 FROM table_1') AS t ON model_1.var_1 = t.var_1 AND model_1.var_2 = t.var_2
2)I do the DMX query to get the node_description from the model.content iterating each row from the result of my prediction query, this query is like this:
SELECT node_description FROM model_1.content WHERE node_name = 'node_name_var'
In this query node_name_var = PredictNodeId(predict_var) from my prediction query.
What I want to know if there is a way to merge Query 1 and Query 2 so I can get the node_description in the same query qhere I get the PredictNodeId.
Hi After building a model in BI, I want to view the chart of model in mining model viewer, in the chart tab I can just see one prediction value that means for my model do prediction for some time slice and in prediction steps I can specify how many steps, I want to show this chart In mining model viewer tab we can see the chart of prediction also decision tree and the chart is for showing all of value prediction, and with choosing prediction steps we can specify that show just one value prediction or two or several values. But sometime I can see just one value in chart and sometime I can see several values in chart, This difference is for my data or no? And also for viewing historic prediction I should choice €śshow historic prediction€? and before that I should set Two parameters: Historic_ model _count and historic _model _count, But I can€™t see historic prediction (sometime this happens) Please help me.
Where I am trying to find out the associations between various service activities so that when a customer buys a service activity we can recommend him/her others
I'm building a mining model wiht MS Association Rules. After processing this model, the result includes some rules(example):
E = Existing, C = Existing -> B = Existing F = Existing -> E = Existing C = Existing, B = Existing -> E = Existing F = Existing -> B = Existing B = Existing, A = Existing -> C = Existing F = Existing, B = Existing -> E = Existing F = Existing, E = Existing -> B = Existing D = Existing -> A = Existing C = Existing -> A = Existing E = Existing, A = Existing -> B = Existing
I want to buid a query that has two or more items on the left of the rules, example: E = Existing, C = Existing -> B = Existing ->I want to buid a query to predict that: when a customer buy 'E' and 'C' then he likely buys 'B'
Is it possible to use two algorithms together?I need to write prediction Query so that its should both models having clustereing algorithm and timeseries algorithm.
for example
I am having student information.I ve to predict performance of students for certain period.The students should be classified by their types like rich kids,poorkids..like that.I need to predict the performance of the rich kids??
Dear friends, I'm reading Wiley's Data mining with SQL Server 2005... There are MANY things I can't understand about MovieClick example (Chapter 3). I hope someone is going to help me with this troubles...
WARNING (1): I'm a dummy both with sql server and data mining. WARNING (2): My English is not good at all.
Just two questions for now:
1) When I create the model to predict the number of bedrooms for homeowners, the book says to check BEDROOMS as Predictable... question: is it also an INPUT for the model, or PREDICTABLE only?
2) I'd like to keep this model (number of bedrooms.......) and make a prediction query.
- Query builder - select case table -> Homeowners - Drag the Customer ID column from the Homeowners table and drop it on the grid - Drag the BEDROOMS column from the mining model and drop it on the grid. - On the last row: Source=PredictionFunction, Field=PredictProbability - Drag the BEDROOMS column from the mining model and drop it into Criteria/Argument - Add (i.e.) 'Two or Three' to the field Criteria/Argument
I execute the query and I obtain many rows in a table with the following colums: CustomerID, BEDROOMS and Expression: WHAT DOES THIS MEAN? WHICH INFO DO I GET FROM THOSE NUMBERS? WHAT CAN I LEARN FROM THEM?
Can i use a CASE statement in a prediction query. the following query is throwing me an error
SELECT CASE [Sales Forecast Time Series].[City Code] when 'LA' then 'Los Angeles' WHEN 'CA' THEN 'California' ELSE 'OTHERS' END, PredictTimeSeries([Sales Forecast Time Series].[Sales Value],5) From [Sales Forecast Time Series]
ERROR: Parser: The statement dialect could not be resolved due to ambiguity.
Also
Is it possible to discretize the Sales Value column using a the CASE statement, the output column of PredictTimeSeries function.
Is there a link that can give me a comprehensive info on what can be achieved and what cant be using DMX queries
hi,I am a novice SSAS Programmer.I need a prediction Query in time series algorithm, so that it should predict for a particular date.I dont know how to use where condition in a prediction Query.
Can anyone show me how to run a prediction query and save the results to a sql table without using the T-SQL OPENQUERY tip here http://www.sqlserverdatamining.com/DMCommunity/TipsNTricks/3914.aspx? I am looking for an example in vb.net that I can use in a SSIS script task.
I have a question about what is possible with a prediction query against a nested table. Say I have a basic customer-product case and nested table mining model like so:
Mining Model DT_CustProd ( [Id] , [Gender] , [Age] [Products] Predict ( [ProductName] , [Quantity] ) ) Using Microsoft_Decision_Trees
I can write a query to find the probability of product (and quantity) A like so:
SELECT (select * from Predict(Products,INCLUDE_STATISTICS) where ProductName = 'A' )
FROM DT_CustProd
NATURAL PREDICTION JOIN
(SELECT 'M' AS [Gender], 27 AS [AGE] ) AS t
What if I know that the query customer (M,27) in question has purchased product B, how can I use that in the prediction join to predict product A? The fact that product B was purchased might influence the prediction, right?
I have a question about writing a prediction query against a clustering model that has the same column added more than once.
Per Jamie, I can accomplish some crude weighting by adding a column to my model multiple times. See this post for an explnation... Now that I have that worked out, I was wondering how my DM query would look? If I have Input_A1, Input_A2 , & Input_A3 all being source from the same column in my structure do I have to reference all three when writing my prediction query?
I believe saving prediction query results to relational tables is possible (the BI studio does it!). I am not clear on how to do this w/o the BI studio, which means if I write a DMX query and want to store its output to a relational table, how do I do it?
I have not used log shipping before and find myself in a position where I need to reboot the secondary node and then the primary node and I don't actually need to failover.
Is there anything I need to be aware of. When rebooting the secondary node I assume the transactions will be held in the primary nodes log till the secondary comes back and just carry on once back up?
When rebooting the primary node nothing needs to be done and the log shipping will just start again once it has come back?
But I'm not sure if I have to install SQL Server first on node 2, then add it to the cluster. Or does adding it to the cluster also install the software?
Hi I have three questions about several topics. In this code: public string ConnectionString { get { return "Provider=MSOLAP.3;Data Source=localhost;Initial Catalog=Adventure Works DW"; } }
What is data source and initial catalog and what does this code do? And if I want to use other database how can change this code? (This code is for data mining viewer client project) And in this code: SqlConnection cn = new SqlConnection("Data Source=localhost;Initial Catalog=AdventureWorks;Integrated Security=True"); SqlCommand cm = new SqlCommand("Select AddressID,AddressLine1 from Person.Address", cn); SqlDataAdapter da = new SqlDataAdapter(); da.SelectCommand = cm; DataTable dt = new DataTable(); da.Fill(dt); this.comboBox1.DisplayMember = "AddressLine1"; this.comboBox1.ValueMember = "AddressID"; this.comboBox1.DataSource = dt;
what is comboBox1.DisplayMember and comboBox1.ValueMember ,and what is difference between those ? and other question: in adventure works dw project for data mining predicting ,in forecasting model ,if I want to show the result of this query in the combobox in c# how can I show that? SELECT PredictTimeSeries(amount) From [Forecasting] And again in this code ,it has a result which has two culomns ,on of them is for amount and other column is for time ,in sql I can save this result in exsiting table or neew table with wizard,but I want to Do this work in c#,that€™s mean with a adomdconnection I connect to forecasting model and write this query then in a datagridviwe ,Iwant to see the values of prediction in adventure works dw database. Other question: In €śdataminingviwerclient€? project I change this code and you can see it,for this code I have a form that give servername and catlogname in that and then with clcking on a button I want to show the chart of model in a child form ,but I can€™t.
public Form1 form1 = new Form1(); public string m_ServerName; public string m_CatalogName; public Form3() { m_ServerName = ""; m_CatalogName = ""; InitializeComponent(); }
public string ConnectionString { get { return "Provider=MSOLAP.3;Data Source=localhost;Initial Catalog=Adventure Works DW"; } }
private void ShowModel(Panel panel, string modelName) { AdomdConnection conn = new AdomdConnection(); try { MiningModelViewerControl viewer = null; MiningModel model = null; MiningService service = null;
// Clear any existing controls from the panel if (panel.HasChildren) panel.Controls.Clear();
// Connect to server conn.ConnectionString = ConnectionString; conn.Open();
// Determine the viewer type based on the model service and // instantiate the correct viewer model = conn.MiningModels[modelName]; service = conn.MiningServices[model.Algorithm]; if (service.ViewerType == "Microsoft_TimeSeries_Viewer") viewer = new TimeSeriesViewer(); else throw new System.Exception("Custom Viewers not supported");
// Set up and load the viewer viewer.ConnectionString = ConnectionString; viewer.MiningModelName = modelName; viewer.Dock = DockStyle.Fill; panel.Controls.Add(viewer); viewer.LoadViewerData(null); } catch (System.Exception ex) { MessageBox.Show(ex.Message, "Model Load"); } conn.Close(); when I run this code ,I have one error that say: the €ś object not found parametr name:index Please see this code and answer my question. If you just can answer one of my qestions ,please say. Thanks a lot for your answers.With best wishes for you
I'm contemplating running two availability groups on a two node WSFC. The WSFC is setup with a file share witness (i.e. no shared storage). Can I safely run 1 AG on one primary node, and the other AG on the other node (as primary). Each AG would have replicas on the passive node. This would effectively allow both servers to be in use at the same time. In a failover event, I understand that both workloads would transfer to a single server - so the box needs to be sized appropriately.
We are in the process of building a 3 node SQL Server Cluster (Server 2012/ SQL Server 2012), and we have configured the quorum so that all 3 nodes have a vote (no file share witness as we already have an odd number of nodes).
As I understand it, this should allow the cluster to run as long as 2 of the nodes remain online.
However, the validation report states that 2 node failures would be acceptable and, when we tested this by powering off two of the nodes, the cluster did indeed continue to run on a single node.
I configure Windows 2003 R2 and SQL 2005 two nodes Cluster. When I move cluster resource from one node to anther node it takes around 30 seconds to become online. So in that time if any query is running it stops responding.
Hi all. Here's my problem: I have a tree linking macaddresses (bigints)in a tree structure. i want to get the path from node a to b.create table tree1(father bigint , child bigint);insert into tree1 (father,child) values (100,200);insert into tree1 (father,child) values (100,300);insert into tree1 (father,child) values (100,400);insert into tree1 (father,child) values (200,2000);insert into tree1 (father,child) values (200,3000);insert into tree1 (father,child) values (100,4000);insert into tree1 (father,child) values (2000,11111);you can see that 100 --> 200 --> 2000 --> 11111select * from tree1what i would like is a query that given two parameters returns the pathbetweenthem, in the case of 100,11111 i want to get100200200011111if possible as different rows, but columns will do to.of course i do not know the legnth of the path. it can be very bigthx in advanceTzvika
I invoke xp_cmdshell proc from inside a stored procedure on a 2-node active/passive SQL 2005 SP2 Standard cluster. Depending on which server the xp_cmdshell gets executed on I need to pass different arguments in the shell command. I thought I could use host_name() function to get the runtime process server, however, I am finding that it's not behaving correctly. In one example I know my active node is server2, but the host_name() function is returning server1. The only thing that I could possible explain this is that the MSDTC cluster group is not always on the same active node as the SQL server group and in the case I am talking about the cluster groups are in this mode (differnet nodes). Does the xp_cmdshell get executed by the SQL active node or the MDTC active node? And what is the best way to find out which server is going to run my xp_cmdshell?
Thanks.
Edit:
Perhaps another by product of this is that if I run select host_name() from the Studio Management query window i get different results depending on which server I am running the Studio Management on. On server1 I get server1 and on server 2 I get server 2, all the while server2 is the active node. I need a different function that will always let me determine the correct server that'll be running the xp_cmdshell...
Edit 2: I guess I could determine the running host inside the command shell itself, but I am curious to see if i can do it (cleaner) from SQL.
Well thanx a lot because i've got the reply. And now i want to ask about prediction data mining using DTS. Should i make some code to perform in my vb application? and how to join my table case with the tree result?
Hi , I am a novice Data Mining Programmer. I am using Time series algorithm for forecasting. We are Quite concerned about the accuracy of Prediction output. For Example Our Data is like this
If I write my Prediction Query to predict for 100 th time step.Its giving me out put like
Date Perf 03/01/2015 47.000000115
We are not sure about the accuracy of the values. Is it possible to use trend information as input to my model and make my prediction based on that. I don€™t know how to do that? Can anyone help?
I am using time series agorithm.I need standard deviation in %. I am using SELECT StudID, PREDICTSTDEV([Perf]) FROM [Stud_Model].This one is giving me the standard deviation like this
I want to add a column to a table that contains the predicted value according to a decision tree mining model. (I know that this is possible). But now I would like that when a new row is added to this table, and every column except the prediction column is filled in manually, can ms sql server add the predicted value automatically for this row? I know it is possible to execute a Singleton query for this kind of single prediction, but I would like to integrate this in my data table, because for now my steps would be: - Create the table with one prediction column - Add the known values of all columns for one row - Use singleton query in Mining model prediction tab to know the predicted value - Fill in the predicted value manually in my table.
i have mining model with 20 columns; 10 columns are for data (A1,A2...A10) and 10 columns are for prediction (B1,B2...B10) data is not in nest table, just one table using Association Rules A1 text A2 text ... A10 text
B1 text prediction only B2 text prediction only ... B10 text prediction only
i have rules as form Ai-->Bj.
i want to make a statement to prediction Bj values when i have Ai values, with Ai get from some textbox on screen, Can you show me some Examples.
I get to page 116 in "Data Mining with SQL Server 2005", but when I try to deploy my model, I get these errors:
