Graduate Research Assistant Higher Education Used the software for: 6-12 months ### "Effective tool to gain AI insights" March 28, 2018 4.0 Pros The tool is very easy to install. Also, the interface is user-friendly. Can handle a lot of machine learning tools. Very handy tool for running quick analysis too. Cons The documentation can be improved substantially. Also, more authority can be given to user to tweek models as per requirement.

Every parameter and hyperparameter of each algorithm is tuneable, and the GUI allows all of this as well. Cons Programmatically using the software is difficult because the documentation is lacking and it is hard to find the documentation that they do have. It’s easier to use the GUI, but that isn’t good for an end-to-end solution. Review Source gK gaurang K.

June 16, 2017 4.0 H2O is a Strong Performer in Predictive Analytics and Machine Learning. Pros Mostly ai can use or automation work. and H2O.ai is a Strong Performer in Predictive Analytics and Machine Learning. Cons In this software main part is use of that software. H2O not user friendly that way user think for uses.

After that, I switch to Python and manually build, tune, train and test my models. Pros I really like H2O machine learning and deep learning algorithms. I use its GUI for preprocessing and analyzing data. I can choose easily model type and tune it via options. It is really fast and run on really low memory like 2 GB. I have learn lotta new information about ML and deep learning thanks to H2O's help buttons. Cons Some model parameters can not be changed. Also I dom't like its preprocessing process. It misreads some characters for some file types. Review Source SR Somnath R.

I can quickly run a lot of well known algorithms without having to code anything at all. The open source nature helps too. Cons The docume.ntation can be improved substantially. Also, need to provide the ability to tweak some algorithms.

It's really useful when you are trying to optimize the parameters. Pros AutoMl is really useful and saves hours of work. H2O flow is easy use and it's very easy to get started using H2O flow. There is also support for python and R Cons There is no feature engineering. Depending on your data size, H2O.AI can take up lots of memory.

Cons The H2o.ai version is great (per a trial) but quite expensive and seems to be focused only on enterprises. A version for SMEs or smaller businesses would be great!

Most of the ML algorithms are supported and available to use. It's easy to launch H2O from R and it noticeably increases the speed of algorithms and reduces time. Cons It would be great if they provide more documentation and guideline. Review Source SK Steve K.

Makers have the power to steer towards opportunities, self-organize and ship products with zero organizational barrier between the product and customers. Worth it with all the analytics Cons lack of management and no accountability. It's hectic and unorganized to the point where you'll have no idea what you're doing, and what you should be doing.

Student Information Technology and Services Used the software for: Less than 6 months ### "Easy to set up and run, nice interface" November 17, 2017 5.0 try some ideas quickly. Pros Notebook's nature of keeping things in one place. Some nice build-in features to interact with different data resources. Cons Less well documented developing guideline. It's some what difficult to build something above it. Notebook has its own shortcomings, which some operations seem less convenient. For instance, if the error output is too lengthy, I have to scroll all the way up to get where I need edit the code. Review Source Similar Products Featured
