This document discusses how graph data science can be used as a secret ingredient for relationship-driven AI. It explains that traditional machine learning ignores network structure, but graph databases can store and retrieve relationships to make AI more contextual. Graph algorithms and embeddings can infer relationships and enrich data. The document provides examples of how knowledge graphs can be used for applications like recommendations, fraud detection, and knowledge management. It also outlines the key components of graph data science including graph algorithms, machine learning workflows, and the Neo4j graph database platform.
In diesem Webinar wollen wir einen Überblick über unser Angebot für Data Scientsts geben und zeigen, was heute schon relativ einfach und schnell möglich ist.
Government GraphSummit: Leveraging Graphs for AI and MLNeo4j
Phani Dathar, Ph.D., Data Science Solution Architect, Neo4j
Relationships are highly predictive of behavior. Graph technology abstracts connections in our data so businesses can apply relationships and network structures to make better predictions. Hear about the journey from graph analytics and machine learning to graph-enhanced AI. We’ll also cover how enterprises are using graph data science in areas such as fraud, targeted marketing, healthcare, and recommendations.
Graphs make implicit relationships explicit and graph data science infers new relationships, derives semantics, and enriches the overall context transforming the graphs with natural relationships to truly knowledge graphs. In this session, let’s talk about the journey from graphs to knowledge graphs and leveraging unsupervised graph algorithms and graph analytics to analyze the complex features in your data and deliver deeper insights.

Relationships Matter: Using Connected Data for Better Machine LearningNeo4j
Relationships are highly predictive of behavior, yet most data science models overlook this information because it's difficult to extract network structure for use in machine learning (ML).
With graphs, relationships are embedded in the data itself, making it practical to add these predictive capabilities to your existing practices.
That’s why we’re presenting and demoing the use of graph-native ML to make breakthrough predictions. This will cover:
- Different approaches to graph feature engineering, from queries and algorithms to embeddings
- How ML techniques leverage everything from classical network science to deep learning and graph convolutional neural networks
- How to generate representations of your graph using graph embeddings, create ML models for link prediction or node classification, and apply these models to add missing information to an existing graph/incoming data
- Why no-code visualization and prototyping is important

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

What’s the Problem?
Generating personalized recommendations is hard due to high
dimensionality and sparse data sets
● History for every customer to generate personalized recommendations
○ Increases the problem of **sparse** and insufficient information
● Reduce dimensionality by matrix factorization and content (word)
embeddings
○ Only suited for content based recommendations
● Macro level insights for cold start problem
○ Generates poor recommendations
7. Neo4j, Inc. All rights reserved 2022
Take advantage of
● graphs to capture the
network structure
● graph queries to store

relationships
● graph algorithms to
infer relationships
