Users are constantly searching for new content and to stay competitive organizations must act immediately based on up-to-date data. Outdated recommendations decrease the likelihood of presenting the right offer and make it harder to maintain customer loyalty. In order to provide the most relevant recommendations and increase engagement, organizations must track customer interactions and re-score recommendations on the fly. Data sources have expanded dramatically to include a wealth of historical data and a constant influx of behavior data. The key to moving from predictive models, applied in batch, to models that provide responses in real time, is to focus on the efficiency of model application. The speed that recommendations can be served is influenced by: Architecture of the recommendation serving platform Choice of recommendation algorithm Datastore access patterns In this presentation, we’ll discuss how developers can use open source components like HBase and Kiji to develop low-latency recommendation models that can be easily deployed by e-commerce companies. We will give practical advice on how to choose models and design data stores that make use of the architecture and quickly serve new recommendations.

Discover, Load, Transform and Mashup. Microsoft Power Query for Excel includes a powerful query engine and a formula language that enables self-service data integration and shaping over a diverse set of data sources. Power Query makes it possible for analysts to do basic ETL by themselves without much help from the IT department. Most common tasks can be accomplished within an intuitive user interface, but a powerful language called “M” can also be used to do some pretty sophisticated data preparation work. Come learn how to succeed and tackle your data and data-shaping needs.

While designing and building Data & AI platforms, you may need to evaluate the options available. Whether your platform would be on-premise or you could use cloud/s services or you would take a hybrid approach. In any case, you may need to look and evaluate various tools & services for your ingestion, storage, process/analysis and serving layers. In this post, I have mapped open-source and popular managed cloud services to make our evaluation process a bit easier.

At GoDataFest 2019, Guy Kfir presented how AI delivers a new experience to Formula 1 fans across the world. AWS fuels the analytics through machine learning. Did you know a Formula 1 race car contains 120 sensors and generated 3 GB of data every race at 1,500 data points per second? AWS developed several applications, including overtake possibility, pitstop advantage. How important is it for your company to invest in Machine Learning and AI? There are three scenario's for AI/ML success: Automation, Enrichment and Invention. So, what are you waiting for: create the loop, advance your data strategy and organize for succes. To get started identify AI/ML use cases, educate yourself, start with AI services and move to Amazon Sagemaker, engage with AWS, consider the partner eco system (like GoDataDriven or Binx).

Power BI is a tool which provides users with very intelligent statistical analysis of raw data and to derive beautiful reports out of it using hundreds of power Visualization. Not just it Power BI provides a build in advantage of Power Views and Power Queries derived from Excel as a base with a very easy process learning. I personally call it very Intelligently dumb tool, because its so easy for normal user to use it and make highly interactive reporting and Dashboards. The Dashboard which are created can be shared with multiple users with specific permission levels to access the reports.

Chances are, your role in IT has been changing as the needs of the business have changed. But the forces outside your company are now driving that change at an ever increasing pace. This environment means that you have a great opportunity to partner with your business colleagues to truly innovate rather than just do "break/fix". Understanding what business intelligence is and how it can help your business is a great place to start. The world of business intelligence (BI) goes beyond what most think of as just "reporting". It has nuances and complexities that require a combination of skills and people. For example, are you ready to help your company understand the difference between analytical reporting and prescriptive reporting? What about "Big Data" and Data Mining? As a SharePoint Professional, you want to be aware of what is possible.

Most of the attention around Analytics goes to the results of the Analytics activity - a better customer profile, a new target market, more efficient product design. What about the process and infrastructure that is needed to get the data to the point in which it is useful to the Analytics community? This presentation addresses the less glamorous, but critically important side of Analytics: the people, process and technology infrastructure that enable an analytics-driven organization. The presentation will cover these questions: • How do you align your information assets to your Analytics goals? What data do you need and where do you find it? • What are the organizational constructs that need to be considered to integrate Data Governance and Analytics? • What organizational change can be anticipated and how should it be addressed? • How do you design your data management and data governance programs to support Analytics? How is this different than an operational use case? This slide deck is drawn from a tutorial presented jointly with Samra Sulaiman of ConsultData at Enterprise Dataversity 2015.

ING is using Apache Flink for creating streaming analytics ('fast data') solutions. We created a platform with Flink and Kafka that offers high-throughput and low-latency, ideally suited for complex and demanding use cases in the international bank such as customer notifications and fraud detection. These use cases require fast data processing and a business rules engine and/or machine learning evaluation system. Integrating these components together in a always-on, distributed architecture can be challenging. In this talk, we'll start with a brief overview of the use cases. You'll learn why ING chose Flink for these use cases, and see the architecture of the streaming data platform in depth. Finally, we'll share some lessons learned and useful insights for organizations who embark on a similar journey.

SharePoint migrations rarely turn out as you plan them. They are sometimes risky and too often take longer than planned. Over the last 10 years of migrating from SharePoint 2003, 2007, 2010 to the latest versions of SharePoint/Office 365 we’ve seen a consistent theme -- organizations underestimate the complexity and level of effort required for a successful, smooth migration. Whether you are planning to complete your own migration, or engaging a vendor to assist, this webinar will discuss precautions you can take to avoid the slippery slope experienced in SharePoint migrations. Join Jill Hannemann, Adam Levithan and our special guest Ryan Tully from Metalogix as they: - Go through the assessment steps to understand the full landscape of your existing SharePoint environment - Review methodologies for moving content from one environment to the next - Outline precautions you should take in migrating to either SharePoint 2013 on-premise or online

Heather Hedden, Senior Consultant at Enterprise Knowledge, presented “Enterprise Knowledge Graphs: The Importance of Semantics” on May 9, 2024, at the annual Data Summit in Boston. In her presentation, Hedden describes the components of an enterprise knowledge graph and provides further insight into the semantic layer – or knowledge model – component, which includes an ontology and controlled vocabularies, such as taxonomies, for controlled metadata. While data experts tend to focus on the graph database components (RDF triple store or a label property graph), Hedden emphasizes they should not overlook the importance of the semantic layer.

Syngulon’s technology expands the capacity for selection of microorganisms. The ability to select individual microbes with a behavior of interest is essential, whether for simple cloning at the bench, or for industry-scale production. Synthetic biology uses the concept of “bioengineering” to improve or modify existing genetic systems to create microbes with desired behaviors, and Syngulon uses this approach to develop its selection technologies. This selection technology is based on bacteriocins, ribosomally-produced peptides naturally made by most bacteria to kill competitive microbial species. These bacteriocins can have a limited or wide target range against other microbial species. This technology offers advantageous over antibiotic selection for several reasons: it avoids the use of antibiotics in the first place, helping to reduce the spread of antibiotic resistant microbes. The technology also increases product yield; as bacteriocins are generally smaller peptides, they do not impose a heavy metabolic burden on the producing cell. They can have a wide target specificity, helping to avoid genetic drift. Finally, our system is 100% plasmid-based (e.g. without chromosomal mutations), making it applicable for use in any E. coli strains.
