Open source, good for basic data mining use cases except for the visualization results

Pros

"It is a stable product."

Cons

"While it might offer insights for basic warehouse tasks, it falls short of deeper understanding and results. "

A good solution offering a range of tools but is limited by its user-handling capacities

Pros

"In Weka, anyone can access the program without being a programmer, which is a good feature since the entry cost is very low."

Cons

"In terms of scalability, I think Weka is not prepared to handle a large number of users. "

No coding required, simple deployment, and highly scalable

Pros

"Weka eliminates the need for coding, allowing you to easily set parameters and complete the majority of the machine learning task with just a few clicks."

Cons

"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."

Cons

"A few people said it became slow after a while."

Relatively stable with excellent accuracy and there's no need to know coding

Pros

"With clustering, if it's a yes, it's a yes, if it's a no, it's a no. It gives you a 100% level of accuracy of a model that has been trained, and that is in most cases, usually misleading. Classification is highly valuable when done as opposed to clustering."

Cons

"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. "

Has a great interface, and good documentation and algorithms

Pros

"The interface is very good, and the algorithms are the very best."

Cons

"Weka could be more stable. "

Can plug in any machine learning algorithm and it works perfectly but needs better visualization

Pros

"Weka is a very nice tool, it needs very small requirements. If I want to implement something in Python, I need a lot of memory and space but Weka is very lightweight. Anyone can implement any kind of algorithm, and we can show the results immediately to the client using the one-page feature. The client always wants to know the story. They want the result. "

Cons

"If you have one missing value in your dataset and this missing value belongs to a specific attribute and the attribute is a numeric attribute and there is only one missing data, whenever you import this data, the problem is that Weka cannot understand that this is a numeric field. It converts everything into a string, and there is no way to convert the string into numerical math. It's really very complicated. "

You can standardize data in an easier way but it should work with big data

Pros

"There are many options where you can fill all of the data pre-processing options that you can implement when you're importing the data. You can also normalize the data and standardize it in an easier way. "

Cons

"The product is good, but I would like it to work with big data. I know it has a Spark integration they could use to do analysis in clusters, but it's not so clear how to use it."
