I am brand new to WEKA and ML, so please excuse my ignorance with the following. I've wasted several hours trying to figure it out, so hopefully someone could point me in the right direction:
I am trying to run a J48 decision tree on data for USDJPY. The data was loaded via .csv file and the class value is of nominal type, more specifically a value of TRUE or FALSE if USDJPY was trading more than 1% higher after 20 sessions. The problem is, When I run the algorithm, the decision tree is simply using the class value to solve the problem, which is useless.
When comparing my dataset to the example "glass" dataset, I cannot find any difference between the two that would explain my problem. "glass.arff" works as expected when I run J48 (with identical settings) by trying to predict the class value (type of glass) via the other attributes (ie it gets some guesses wrong).
What am I missing here? Perhaps it has something to do the .csv source file type?

Hi together,
there is a textfield stored in a table of a MySQL-database containing HTML-Code which is stored by most popular CKEditor-component.
It's just like this POST-Editor at your community-site to put any questions into that forum.
On Report-Desinger the textfield-attribute for "Rich-Text-Type" is set to "text/html". Inspite of this setting HTML-Tables are not shown as such tables and also images are ignored.
Is there a plugin or a java-aplet which supports this feature?
Recommended features are:
- Tables like
| Property-List |
Value-List |
| Property-A |
Value of A |
| Property-B |
Value of B |
- font-property-support like
- bold, underline, italic
- fontsize
- font-type
- text-alingnment like tabs or listentries (looking like these list)
- images
Thanks for reply!

Hello Friends,
I am running into an issue where I am finding it hard to explain a phenomena. Any help is much appreciated
Basically, I he a dataset with 25 attributes which is logically separated into three categories (A,B,C). When I run the test with Random Forest wit all attributes combined, I get accuracy of 93% (93/100 is correctly predicted). But when I run the test with different logical features separately and combine the results, it ends up correctly predicting more than 93 instances. To be more clear, I am attaching a picture.
As shown in the picture, combination accuracy(93)is lower than hen splitting. My best guess I that I happens because of the correlation between the features. But I am myself not satisfied with that rationale.
Thanks.

I configured smtp server in spoon with no port details, I get an email alert, the same transformation I run from PAN it fails with error
"Could not connect to SMTP host:<smtp host name> , port: 25
then I tried to use port 25 from Spoon with TLS authentication, the spoon job successfuly completes but I didn't receive any emails. the same job I run from PAN it gives the same error "Could not connect to SMTP host:<smtp host name>, port 25.
Please suggest ho to resolve this.

Hi,
I have a database lookup step that is retrieving 3 fields from a SQL Server table. One of the fields is a decimal (8,6). When retrieved, the field values appear to be integers, losing all decimal places. I have spent several hours trying to resolve this issue and have found a reference to using an alter step to ensure the decimal places are available.
In the database lookup step I have tried different data types (number, string etc.) and I've followed this with a select values step, where I'm altering the field to a number field with decimal places. Nothing has worked, so any help with what I'm sure should be a simple problem to solve would be greatly appreciated. Apologies if the answer is obvious and I've missed it.

Hello everybody! Here I'm, again.
This time, I have a question about something that I don't know if can be done. I want to look in the content of a .txt if exist at least one word of a pre-made list (in a .csv). I did some research, but I do not found a step that does something similar... I try with RegEx Eval. but I can't import the words list to the expression, and transcribe the xxx words in a RegEx... Is not an option. Try with Stream Lookup, but I want to look if the .txt contain the words, not if the .txt content is equal to the word.
Thanks.

I am using "Load file content in memory" step to read the file contents of the unstructured text files. I want to extract a string from the File content, and it gives me the null value in the output. When I test that regex using the "test regex" utility in the Regex evaluation step, it extracts the string I want. I tested my regex in some online Regex compilers too and it is valid. Any suggestions?

Team:
I have been using 4.3 for MANY years and decided it was time to upgrade. I considered myself decent in being able to
search for answers to many of my questions but failed quite a few things on the upgrade. Even basic things
File I grabbed pdi-ce-6.1.0.1-196.zip (unix system based)
1. I see the new Repo is suggested to be via a web server
- Everything I see tells you HOW to connect but not how to install/setup something (or even what is needed) to create the service
2. I attempted to fall back to the standard DB Repo
- I put all the *.jar files into the ./lib dir (I kept most of the jar files updated on 4.3) - Restarted spoon.sh
- I cant connect to the local mysql DB
I have done as many google searches as I thought were legit.. Can someone give me a few clues here?
Thank you

I have a aggregate tables for fact table. There is an avg measure [Measures].[Pc in avg by hour] in cube. I dont understand why mondrian covert this MDX query:
Code:
SELECT {[Measures].[Pc in avg by hour]} ON COLUMNS,
[Renter].Children ON ROWS
FROM [Renter]
to this SQL query:
Code:
select `renter`.`id` as `c0`,
sum(`agg_r_renter_fact`.`pc_in_avg_by_hour`) / sum(`agg_r_renter_fact`.`fact_count`) as `m0`
from `renter` as `renter`, `agg_r_renter_fact` as `agg_r_renter_fact`
where `agg_r_renter_fact`.`renter_id` = `renter`.`id`
group by `renter`.`id`
instand of this:
Code:
select `renter`.`id` as `c0`,
avg(`agg_r_renter_fact`.`pc_in_avg_by_hour`) as `m0`
from `renter` as `renter`, `agg_r_renter_fact` as `agg_r_renter_fact`
where `agg_r_renter_fact`.`renter_id` = `renter`.`id`
group by `renter`.`id`
How i see. Mondrian have a bug with avg measure and aggregate table. Or is it my mistake?

Will the Metadata injection step pass data rows to the target transformation? All the examples I've found are using metadata injection to modify a transformation that's self contained, i.e they read from a file, do something and write it out. I'm trying to use it with a transformation that expects the input data rows to be supplied from the previous transformation.
