Support and flexibility enable effective project initiation and meet customer needs but deployment requires enhancement
The customer comes to you and says they want to deploy it and make a production out of this, which is very difficult and expensive with IBM SPSS Modeler. With MATLAB, there is no problem. I have a solution, and then I convert my MATLAB solution to C programming language. This I can deploy, and I can check it, and it is MISRA compatible. It is very easy to deploy it, to go from MATLAB to C or C++, which is actually needed in the car industry. In the car industry, they want to have it in the hardware. You cannot put MATLAB or IBM SPSS Modeler in the hardware of a car, but with C, there is no problem with a microcontroller. They can shoot it into the microcontroller, and I can check it with Polyspace, and it is MISRA compatible, which is an industrial standard. There is nothing similar in IBM SPSS Modeler. I made solutions with IBM SPSS Modeler, and then the customer said they wanted to make a production out of it, and it was not possible. I stopped with IBM SPSS Modeler 18. It is now 18.6 from what I know at the moment. I do not believe that there is a possibility to design a graphic user interface with it. It is itself a graphic user interface, where you put all sorts of little icons into the display.

Data mining projects have become faster and visualization now guides our pattern discovery
Weka can be improved in some areas. As a one-year user, I can share my experiences. I have tried installing other packages into Weka using the inbuilt package manager or adding modern algorithms that I wish to apply to my data sets or data processing. I think Weka needs to improve in that and also in integrating Python into Weka, which would help users much more. I chose eight out of ten because we need improvements in Weka, such as installing inbuilt packages. Weka uses skips such as N+2 or N+4 and eight-node, which makes sense basically, but I think it should improve in the package attribute, such as configuring Python easily and adding modern algorithms into Weka more easily.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It helped me in that I didn't need to write them by hand, and I could get a result in one or two minutes. That helped me a lot."
"It is a pretty stable solution, the end-users and other people with hands-on experience are very happy with this tool, it has not let us down in the past, and we have not really experienced any downtime."
"It is pretty scalable."
"Very good data aggregation."
"It will scale up to anything we need."
"It scales. I have not run into any challenges where it will not perform.​"
"I used it mostly for the PCA, the principal component analysis, and I have been using that for my bachelor's thesis."
"The supervised models are valuable. It is also very organized and easy to use."
"Weka's best features are its user-friendly graphic interface interpretation of data sets and the ease of analyzing data."
"If they want their task done faster, and they do not have enough coding expertise, this is definitely an excellent solution to choose from."
"Weka's best features are its user-friendly graphic interface interpretation of data sets and the ease of analyzing data."
"In Weka, anyone can access the program without being a programmer, which is a good feature since the entry cost is very low."
"Weka is a very nice tool and it helped me to solve any machine learning problem in one minute."
"The path of machine learning in classification and clustering is useful. The GUI can get you results. No programming is needed. No need to write down your script first or send to your model or input your data."
"The interface is very good, and the algorithms are the very best."
"Weka is just much better for the classification path and clustering path; if you are going with some predictions that a procedure recalls, it's better than any other tool like R Programming and Python."
 

Cons

"The time series is a very important issue, however, it is not given its value in the package as it should be."
"The platform's cloud version needs improvements."
"When I used it in the office, back in the day, we did have some stability issues. Sometimes it just randomly crashed and we couldn't get good feedback."
"The integration with sources and visualisation needs some improvement. The scalability needs improvement."
"It is not integrated with Qlik, Tableau, and Power BI."
"That, to me, has always been the biggest flaw in using this. It's very difficult to get good visualization."
"The standard package (personal) is not supported for database connection."
"It would be helpful if SPSS supported open-source features, for example, embedding R or Python scripts in SPSS Modeler."
"The filter section lacks some specific transformation tools."
"The visualization of Weka is subpar and could improve. Machine learning and visualization do not work well together. For example, we want to know how we can we delete empty cells or how can we fill in the empty cells without cleaning the data system and putting it together."
"Weka is a little complicated and not necessarily suited for users who aren't skilled and experienced in data science."
"Weka is not horizontally scalable. If I had to run a large dataset over Weka I would have to have a very large usage."
"The filter section lacks some specific transformation tools. If you want to change a variable from a numeric variable to a categorical variable, you don't have a feature that can enable you to change a variable from a numeric variable to a categorical variable."
"While it might offer insights for basic warehouse tasks, it falls short of deeper understanding and results."
"Scalability and performance are the main aspect of improvement in Weka, since it has the main Java limitations, regarding the JVM."
"For production, it's not the best option."
 

Pricing and Cost Advice

"I am using the free version of IBM SPSS Modeler, it is the educational edition version."
"It is an expensive product."
"$5,000 annually."
"Its price is okay for a company, but for personal use, it is considered somewhat expensive."
"Having in mind all four tools from Garner’s top quadrant, the pricing of this tool is competitive and it reflects the quality that it offers."
"When you are close to end of quarter, IBM and its partners can get you 60% to 70% discounts, so literally wait for the last day of the quarter for the best prices. You may feel like you are getting robbed if you can't receive a good discount."
"The scalability was kind of limited by our ability to get other people licenses, and that was usually more of a financial constraint. It's expensive, but it's a good tool."
"It is a huge increase to time savings."
"Currently, I am using an open-source version so I don't know much about the price of this solution."
"As far as I know, Weka is a freeware tool, and I am not aware if they have an online solution or if it is a commercial product."
"We use the free version now. My faculty is very small."
"The solution is free and open-source."
