Graph Database: How Graph Is Being Utilised For Data Analytics

#artificialintelligence

In computing, a graph database (GDB) is a database which utilises graph structures for semantic queries with nodes, edges, and properties to represent and store data. The graph related data items in the store to a collection of nodes and edges, where edges are representing the relationships across the nodes. Graph databases are a kind of NoSQL database, built to address the limitations of relational databases. While the graph model clearly lays out the dependencies between nodes of data, the relational model and other NoSQL database models link the data by implicit connections. Graph databases are the fastest-growing category in all of data management.


Predictive engineering analytics, big data and the future of design

#artificialintelligence

By combining physics-based simulations, data mining, statistical modelling and machine learning techniques, predictive engineering analytics can analyse patterns in the data to construct models of how the systems you gathered the data from work. IoT and sensors are already transforming products and mining the stream of information from products will be critical for maintaining products and designing their replacements. For many industries, the products they create are no longer purely mechanical; they're complex devices combining mechanical and electrical controls. That means engineering different systems, and the ways they interface with each other, and with the outside world. At one level you're coping with electromechanical controls, at another, you're creating a design that covers the cooling requirements for the electronics.


How Data is Redefining A&R's Role In The Modern Music Industry - Hypebot

#artificialintelligence

Although A&Rs are still looking for the same qualities in an artist as they were fifty years ago, what they're looking for in that same artist's data – and they way they're looking for – it has changed dramatically. Editor's Note: Tommaso Rocchi is a 2020 Master of Arts graduate of The Global Entertainment and Music Business program at Berklee College of Music in Valencia, Spain. Data-driven A&R has been a buzzword for quite some time in the music industry, but also one of its most guarded secrets. Even before the acquisition of Sodatone by Warner Music Group, major and big indie record labels started to switch their mindsets and focus on the advantages of a data-driven approach. Compared to the classic "gut-feeling" expertise of a senior A&R, data analysis allows today's A&Rs to validate their intuition and justify talent acquisition with predictive modeling.


There's no data science unicorn - building a data team at HSBC

#artificialintelligence

HSBC is one of the world's largest financial institutions, serving more than 40 million customers globally. One of its largest divisions, Wealth and Personal Banking, supports individuals, families, business owners, investors and entrepreneurs. It provides products and services that include current accounts, credit cards, personal loans and mortgages, as well as savings, investments, insurance and wealth management. At the centre of the Wealth and Personal Banking division is a data analytics group, which is responsible for providing data-tailored services to HSBC teams and customers all around the world. Rahul Boteju, Global Head of Data Analytics at HSBC, was speaking this week at the Big Data LDN event, where he shed some light on what it takes to build an effective data science team that can scale.


Q&A with a Data Scientist

#artificialintelligence

I'm Vegard, and I currently work as the Lead Data Scientist in a software company called Axbit. In addition to that I also have a part-time position as an Associate Professor in machine learning at Molde university college. Today I am happy to answer a couple of questions related to data science, what data science is all about and how working within this field is like. Transcript: How did I become a data scientist? First of all, I think my background is probably a bit different compared to a lot of other data scientists.


Global Big Data Conference

#artificialintelligence

The machine learning and AI-powered tools being deployed in response to COVID-19 arguably improve certain human activities and provide essential insights needed to make certain personal or professional decisions; however, they also highlight a few pervasive challenges faced by both machines and the humans that create them. Nevertheless, the progress seen in AI/machine learning leading up to and during the COVID-19 pandemic cannot be ignored. This global economic and public health crisis brings with it a unique opportunity for updates and innovation in modeling, so long as certain underlying principles are followed. Here are four industry truths (note: this is not an exhaustive list) my colleagues and I have found that matter in any design climate, but especially during a global pandemic climate. When a big group of people is collectively working on a problem, success may become more likely.


Maybe Businesses Don't Need To Worry So Much About Inference

#artificialintelligence

I want to talk about a misconception on the difference between inference and prediction. For a well run analytically oriented business, there may not be as many reasons to prefer inference over prediction one may have heard. A common refrain is: data scientists are in error in centering so much on prediction, a mistake no true Scotsman statistician would make. I've actually come to question this and more and more. Mere differences in practice between two fields doesn't immediately imply either field is inferior or in error.


Event Stream Processing: How Banks Can Overcome SQL and NoSQL Related Obstacles with Apache Kafka

#artificialintelligence

While getting to grips with open banking regulation, skyrocketing transaction volumes and expanding customer expectations, banks have been rolling out major transformations of data infrastructure and partnering with Silicon Valley's most innovative tech companies to rebuild the banking business around a central nervous system. This can also be labelled as event stream processing (ESP), which connects everything happening within the business - including applications and data systems - in real-time. ESP allows banks to respond to a series of data points – events - that are derived from a system that consistently creates data – the stream – to then leverage this data through aggregation, analytics, transformations, enrichment and ingestion. Further, ESP is instrumental where batch processing falls short and when action needs to be taken in real-time, rather than on static data or data at rest. However, handling a flow of continuously created data requires a special set of technologies.

How to pick a cloud machine learning platform? To create an effective machine learning and deep learning model, you need more data, a way to clean the data and perform feature engineering on it. It is also a way to train models on your data in a reasonable amount of time. After that, you need a way to install your models, surveil them for drift over time, and retrain them as required. If you have invested in compute resources and accelerators such as GPUs, you can do all of that on-premises.
