Title: A tutorial with R


Abstract: The body of knowledge we call machine learning consists of multitude of statistical and heuristic algorithm where data comes in on one side and data which we deem "actionable" "insight" comes out the other.  I will focus on a handful of case studies and will demonstrate how those "my favorite" algorithms can solve business problems.

Title: Image Processing and Image Pattern Recognition - A Programming Tutorial


Abstract: Image recognition is a major area of application of machine learning - evolving at a rapid pace with a number of programming platforms available to developers. While each platform has its own uniqueness, the methodology of image recognition consists of a sequence of image processing tasks, development of a classifier algorithm, training and testing followed by deployment. This tutorial will delve into the programming aspects of image processing including thresholding, contouring and template matching. In order to provide practical hands on programming this tutorial will closely look at three real life applications of image pattern recognition namely ALPR  using Tesseract OCR, vehicle detection using HAAR classifiers and human detection using HOG classifiers. The tutorial will explain the algorithm, implementation of pseudocode through programming languages in Python, Java and C++ using two major platforms: OpenCV and Tensorflow.


This tutorial is aimed at students and professionals with experience in software development and those who would wish to develop competence in image pattern recognition. Many data scientists who are skilled in algorithm development would also find this tutorial of interest. At the end of this tutorial the participants can expect to take away a good understanding of how they can programmatically implement practical applications of image recognition.

Title: Artificial Intelligence with Big Data


Abstract:  Big Data has presented new opportunities for the Artificial Intelligence practitioner. Unlike traditional application development, Big Data application development presents its own unique challenges in order to appropriately harness the utility of open source frameworks including Apache Hadoop and design patterns such as Map – Reduce. Through these advances, Big Data has become ubiquitous across all areas of research allowing for new applications that were not possible earlier.


The tutorial will specifically step each student though the installation, setup and implementation of the Apache Spark architecture on Amazon Web Services. The tutorial will also present a detailed examination of the Spark Distributed Processing platform with examples leveraging the Scala programming language. Machine Learning techniques will also be covered utilizing the ML library on the Scala/ Spark platform. Additional technologies including Python Tensorflow and Scikit-learn are also going to be presented as comparative technologies. Overall architecture design will also be explored as well as the future direction of the Big Data software suite.

Title: Chatbot Technologies and Challenges


Abstract: Chatbots have recently become popular due to the widespread use of messaging services and the advancement of Natural Language Understanding. In this tutorial, we give an overview of the technologies that drive chatbots, including Information Extraction and Deep Learning.  We also discuss the differences between conversational and transactional chatbots – the former are trained on free-form chat logs, whereas the latter are defined manually to achieve a specific goal like booking a flight. We also provide an overview of commercial tools and platforms that can help in creating and deploying chatbots. Finally, we present the limitations and future work challenges in this area.

Title: Combinatorial Algorithms in Machine Learning


Abstract: Although quite old, the classic data clustering problem strives to segment the data into homogeneous groupings where homogeneity is measured by e.g., Gini Index.   Classical techniques, all heuristic, strive to group the data by what one would argue as "smart" trial-and-error procedure. I will show how data could be clustered used an entirely combinatorial techniques where of Gini Index or Mean Squared Error receive no mention whatsoever. The Cluster Editing pattern search algorithm shows a great promise to help solve those intractable high-dimensional problems because it's almost total indifferent to the dimensionality of the data. 

Bio: Dr. Peter Shaw is a senior lecturer at Massey University New Zealand and teachers at Hebut University of Technology Tianjin China. His research is in the area of efficient Fixed-Parameter Algorithms. He also works on the analysis of clinical data and employs these algorithms to do pattern search on multivariate models that I produce from the data using machine learning techniques. I currently am looking at data sets related to Otitis Media (deafness), ALRI (acute lung infections),  human trafficking, and transportation.
