Undergraduate Reseacher , Mechatronics Instrumentation and Control Lab Research Small-Business (50 or fewer emp.) 2/19/2019 "ML Lib a Machine Learning library on Spark" 4/5 What do you like best about MLlib? MLLib was used as part of course in my college for Big Data. So we got to study why actually mllib came about and what all inadequacies were there in the Map-Reduce Framework of Hadoop and how apache Spark has solved them. The best part is the ease of use of Mllib and also the excellent documentation support from both the official website as well as the sources outside like youtube videos. The big community makes it easy to learn and use mllib. I used mllib for decision trees and I being a student was successfully able to implement the same with ease. Plus the python implementation is very easy to implement. Review collected by and hosted on G2.com. What do you dislike about MLlib? We were given a preinstalled system for our labs and a cluster, but when I tried to do the same for my machine, I found it rather tricky to install. Also, support for deep learning is not there, which is a very fast growing field of machine learning. Review collected by and hosted on G2.com. Recommendations to others considering MLlib: Good and easy to use library for multi cluster computing but only for conventional machine learning problems. Currently not adept with the deep learning support which may be nice in the future. Review collected by and hosted on G2.com. What problems is MLlib solving and how is that benefiting you? I did a course on Big Data where I used Hadoop and apache spark to learn the various techniques used to deal with big data. Here I used MLlib to do a course project on classification, where I built a model a decision tree model from the data that I acquired by scraping humongous amount of sites.

I love how it includes most of the popular ML libraries for easy use with Apache Spark and parallelized computing. The power is only limited by the number of cores you've got. Review collected by and hosted on G2.com. What do you dislike about MLlib? I feel like some other ML frameworks have better models, or added features/functionality used in developing models. MLlib is also an open source part of Spark, so development of the framework depends largely on what Open Source folks contribute to it. Review collected by and hosted on G2.com. What problems is MLlib solving and how is that benefiting you? I'm doing ML problems with Apache Spark dataframes. The benefits are we can massively parallelize our training and modeling. I've worked with customers who used MLlib to build out random forest decision trees with massive tree depth and massive tree count. This would be impossible without MLlib.

Data Scientist and Researcher Outsourcing/Offshoring Enterprise (\> 1000 emp.) 4/20/2018 "Distributed ML in Spark with limited flexibility, especially for advanced algorithms" 2.5/5 What do you like best about MLlib? It is distributed and allow distributed execution of model training ans well as model scoring. It helps to leverage benefit of Spark without using Scala. It delivers Spark ML with Python! High performance since it is a RDD-based data modeling package. Fairly nice documentation. Review collected by and hosted on G2.com. What do you dislike about MLlib? It is rigid with some of the algorithms, specially with advanced one like neural network. For instance, you are unable to change activation functions of a neural network. You can either use Sigmoid for all the layers, or tanh which is not really making sense! Evaluation metrics are not as rich as packages like Scikit-Learn. Not all its functionalities implemented in Python. Many are Scala-based yet. Review collected by and hosted on G2.com. Recommendations to others considering MLlib: If you bother about advanced algorithm in specific neural network, do not use MLlib as it does give you least flexibility in customizing the network. Perhaps it is great for regression and decision tree in distributed environment. Review collected by and hosted on G2.com. What problems is MLlib solving and how is that benefiting you? MLlib has both classification and regression algorithms under supervised learning and also k-means under unsupervised learning. The beauty of the package lies in its distributed execution.
