Platforms and Algorithms for Big Data Analytics
This is an era of Big Data. The total digital data in this world is expected to double in less than two years. Big Data is driving radical changes in traditional data analysis platforms and algorithms. This tutorial consists of two parts: (i) Big data platforms and their characteristics (ii) Large-scale classification and clustering algorithms.
The first part will provide an in-depth analysis of different platforms available for studying and performing big data analytics. It will survey different hardware platforms available for big data analytics and assesses the advantages and drawbacks of each of these platforms based on various metrics such as scalability, data I/O rate, fault tolerance, real-time processing, data size supported and iterative task support. Using a star ratings table, a rigorous qualitative comparison between different platforms is made for each of the six characteristics that are critical for the algorithms of big data analytics. In addition to the hardware, a detailed description of the software frameworks used within each of these platforms is also discussed along with their strengths and drawbacks. Some of the critical characteristics that will be described here can potentially aid the audience in making an informed decision depending on their computational needs.
The second part of the tutorial will consist of big data classification and clustering algorithms. In order to provide more insights into the effectiveness of each of the platforms in the context of big data analytics, specific implementation level details of the widely used k-nearest neighbor and the k-means clustering algorithm on various platforms will be described in the form of pseudocode. In addition, recent advances in large-scale linear classification and map-reduce based classification algorithms will also be discussed. In the context of clustering, some of the well-known one-pass clustering algorithms and other parallel and distributed clustering solutions will be briefly mentioned.

The target audience is researchers from both academia and industry including graduate students working in the fields of big data, data analytics, data mining and machine learning. In terms of the prerequisites, we expect the audience to be little familiar with some of the basic concepts of data mining such as classification and clustering. Our immediate goal is to provide an overview of the big data platforms and to educate the research community about the platform characteristics and large-scale data mining algorithms. The ultimate goal is to bridge researchers and practitioners to foster interdisciplinary works between the two groups. This tutorial can also attract researchers from the big data industry as it covers many practical aspects of big data analytics. The tutorial will be primarily targeted for researchers who are interested in analyzing large-scale data. They will become knowledgeable about the platforms and algorithms available to perform various kinds of analysis on large-scale data.
