    Genomic data is outpacing traditional Big Data disciplines, producing more information than Astronomy, twitter, and YouTube combined. As such, Genomic research has leapfrogged to the forefront of Big Data and Cloud solutions using artificial intelligence and machine learning to generate insights from these unprecedented volumes of data. This talk hence showcases how we find the disease genes responsible for ALS using VariantSpark, which is a custom random forest implementation built on top of Spark to deal with the 80 million columns in genomic data. This talk also outlines how we use a serverless architecture to translate these insights onto the clinical practice by provide a decision support framework for clinicians to find actionable genomic insights and process medical records at a speed fit for point-of-care application. Furthermore, the talk also touches on how to evolve serverless architecture more efficiently through an hypothesis-driven approach to DevOps and how we keep data and functions secure in a serverless environment.

    In the last decade, deep neural networks have created a major paradigm shift in speech recognition. This has resulted in dramatic and previously unseen reductions in word error rate across a range of tasks. These improvements have fueled products such as voice search and voice assistants like Amazon Alexa and Google Home.

    The main components of a speech recognition system are the acoustic model, lexicon, and language model. In recent years, the acoustic model has evolved from using Gaussian mixture models to deep neural networks, resulting in significant reductions in word error rate. Recurrent neural network language models have also given improvements over the traditional statistical n-gram language models. More recently sequence to sequence recurrent neural network models have subsumed the acoustic model, lexicon, and language model into one system, resulting in a far simpler model that gives comparable accuracy to the traditional systems. This talk will outline this evolution of speech recognition technology, and close with some key challenges and interesting new areas to apply this technology.

    Applying analytics to determine an optimal answer to business decision problems is relatively easy when the future can be predicted accurately. When the business environment is very complex and the future cannot be predicted, the business problem can become intractable using traditional modeling and problem-solving techniques. How do we solve such complex and intractable business problems to find globally optimal answers in highly uncertain business environments? The talk will discuss modeling and solution techniques that allow us to find optimal solutions in highly uncertain business environments without ignoring or underestimating uncertainty for revenue management and dynamic price optimization problems that arise in the airline and hospitality industry.

    Various Chinese achievements in the field of Artificial Intelligence (AI) has widely been reported in the media recently. Be it a remotely controlled Tank to a demonstration of Swarms of Autonomous UAVs during an Air Show, China is building them fast and possibly in numbers while preparing for 'Intelligized Warfare'. These technology demonstrations are not very far from field deployment and are a cause for worry for several countries. Chinese State Council also released a detailed plan for the development of AI as a tool for the development of the nation, including military application. It is an ambitious plan but China has a strong foundation in its Academia, Public Sector Industry and Startups to make it possible and enable it to become a Global Leader in AI. It is therefore important to examine this foundation of Industry, Startup Ecosystem, Academia and their mutual cooperation to truly understand the potential of China and be able to predict their military deployment of AI.

    Over the last two decades, trading has seen a remarkable evolution from open-outcry in the Wall Street pits to screen trading all the way to current automation and high-frequency trading (HFT). The success of machine learning and artificial intelligence (AI) seems like natural progression for the evolution of trading. However, unlike other fields of AI, trading has some domain specific problems that project the dream of set-it-and-forget-it money making machines still some way in the future. This talk will describe the current challenges for intelligent autonomous trading systems and provides some practical examples where machine learning is already being used in financial applications.

    Apache Spark is an amazing framework for distributing computations in a cluster in an easy and declarative way. Is becoming a standard across industries so it would be great to add the amazing advances of Deep Learning to it. There are parts of Deep Learning that are computationally heavy, very heavy! Distributing these processes may be the solution to this problem, and Apache Spark is the easiest way I could think to distribute them. Here I will talk about Deep Learning Pipelines an open source library created by Databricks that provides high-level APIs for scalable deep learning in Python with Apache Spark and how to distribute your DL workflows with Spark.

    Dr. Dakshinamurthy V Kolluru - ML and DL in Production: Differences and Similarities

    45 Mins
    Talk
    Beginner

    While architecting a data-based solution, one needs to approach the problem differently depending on the specific strategy being adopted. In traditional machine learning, the focus is mostly on feature engineering. In DL, the emphasis is shifting to tagging larger volumes of data with less focus on feature development. Similarly, synthetic data is a lot more useful in DL than ML. So, the data strategies can be significantly different. Both approaches require very similar approaches to the analysis of errors. But, in most development processes, those approaches are not followed leading to substantial delay in production times. Hyper parameter tuning for performance improvement requires different strategies between ML and DL solutions due to the longer training times of DL systems. Transfer learning is a very important aspect to evaluate in building any state of the art system whether ML or DL. The last but not the least is understanding the biases that the system is learning. Deeply non-linear models require special attention in this aspect as they can learn highly undesirable features.

    In our presentation, we will focus on all the above aspects with suitable examples and provide a framework for practitioners for building ML/DL applications.

    Hi! My name is Emil and I am a Teacher Bot. I was built to answer your initial questions about using KNIME Analytics Platform. Well, actually, I was built to point you to the right training materials to answer your questions about KNIME.

    Puzzling together all the pieces to implement me wasn't that difficult. All you need are:

    • A user interface - web or speech based - for you to ask questions
    • A text parser for me to understand
    • A brain to find the right training materials to answer your question
    • A user interface to send you the answer
    • A feedback option - nice to have but not a must - on whether my answer was of any help

    The most complex part was, of course, my brain. Building my brain required: a clear definition of the problem, a labeled data set, a class ontology, and finally the training of a machine learning model. The labeled data set in particular was lacking. So, we relied on active learning to incrementally make my brain smarter over time. Some parts of the final architecture, such as understanding and resource searching, were deployed as microservices.

    In evolutionary history, the evolution of sensory organs and brain plays very important role for species to survive and prosper. Extending human’s abilities to achieve a better life, efficient and sustainable world is a goal of artificial intelligence. Although recent advances in machine learning enable machines to perform as good as, or even better than human in many intelligent tasks including automatic speech recognition, there are still many aspects to be addressed to bridge the semantic gap and achieve seamless interaction with machines. Auditory intelligence is a key technology to enable natural man machine interaction and expanding human’s auditory ability. In this talk, I am going to address three aspects of it:

    (1) non-speech audio recognition,

    (2) video highlight detection,

    (3) one technology to surpassing human’s auditory ability, namely source separation.

    Atin Ghosh - AR-MDN - Associative and Recurrent Mixture Density Network for e-Retail Demand Forecasting

    45 Mins
    Case Study
    Intermediate

    Accurate demand forecasts can help on-line retail organizations better plan their supply-chain processes. The chal- lenge, however, is the large number of associative factors that result in large, non-stationary shifts in demand, which traditional time series and regression approaches fail to model. In this paper, we propose a Neural Network architecture called AR-MDN, that simultaneously models associative fac- tors, time-series trends and the variance in the demand. We first identify several causal features and use a combination of feature embeddings, MLP and LSTM to represent them. We then model the output density as a learned mixture of Gaussian distributions. The AR-MDN can be trained end-to-end without the need for additional supervision. We experiment on a dataset of an year’s worth of data over tens-of-thousands of products from Flipkart. The proposed architecture yields a significant improvement in forecasting accuracy when compared with existing alternatives.
