💡 Revolutionizing Stock Markets with AI
🗓️ Tuesday 25th November 2025
⏰ 12:30 - 1:30 PM GMT
🗣️ Liyana Saleem, Platform Engineer @ IBM & Pardis Farahi, Platform Engineer @ IBM

This session explores how AI is transforming today’s data-driven stock markets, where vast volumes of real-time information shape trading decisions. We’ll introduce how traditional trading approaches are now being augmented by machine learning, NLP, and reinforcement learning to detect patterns, analyse sentiment, and adapt to shifting market regimes. Using a fictional trading simulation, we’ll demonstrate how a simple model can anticipate short-term trends and make decisions informed by a company’s background data. We’ll also highlight real-world applications, examine the key advantages and common pitfalls of AI-driven systems, and touch on the importance of transparency and oversight when applying these tools in practice.

💡 Context-Aware Vision Systems Using Knowledge Graphs
🗓️ Tuesday 25th November
⏰ 15:00 PM GMT
🗣️ Niyati P, Software, ML Lead

Traditional computer vision systems often rely solely on pixel-level features and deep learning to interpret images, limiting their ability to understand complex scenes or generalize across contexts. This talk introduces a new paradigm: context-aware vision systems powered by knowledge graphs. By embedding structured semantic knowledge into vision pipelines, machines can infer not just what is seen, but why it matters. We explore how knowledge graphs provide contextual cues—such as object relationships, scene hierarchies, and domain-specific constraints—that enhance visual perception and reasoning. From improving object recognition in ambiguous environments to enabling semantic scene parsing and zero-shot learning, this approach bridges the gap between raw visual data and high-level cognition. The session will highlight recent breakthroughs, implementation strategies using Graph Neural Networks (GNNs), and applications in domains like autonomous driving, medical imaging, and industrial robotics. Attendees will leave with insights on designing vision systems that not only see—but understand.

💡 Competitor Response Planning Suite - Turning Threats into Strategic Advantage
🗓️ Wednesday 26th November
⏰ 12:30 PM (GMT)
🗣️ Rajat Kumar, Applied Data Science Manager @ dunnhumby and Namish Kaushik, Senior Applied Data Scientist @ dunnhumby

In today’s hyper-competitive retail environment, the presence of a competitor store isn’t just a challenge - it’s a direct threat to customer loyalty, sales, and profitability. This session introduces the Competitor Response Planning (CRP) Suite, a pioneering solution that fuses geo-spatial intelligence with predictive modeling to help retailers proactively counter competitive impact.

Built on the theme of “Innovating with Data”, the CRP Suite is a three-pronged modeling framework designed to predict customer churn risk across New Competitor Advent, Existing Competitor Landscapes and Instore Media Optimization.

The session will showcase how the CRP Suite integrates retailer data with third-party sources to extract key variables—store DNA, customer behavior, and geo-location—and trains custom propensity models tailored to different competitor types. This enables targeted retention strategies that replace generic mass offers with personalized interventions.

Attendees will also explore how the CRP Suite has been productionized into the Voila dashboard, empowering non-technical users to self-serve insights, trigger models, and navigate competitive threats with ease. Whether you're a data scientist, marketer, or business strategist, this session will demonstrate how data innovation can transform competitive threats into strategic opportunities—driving measurable outcomes for retailers and delighting customers through personalization.

💡 Personalization Models for Email Subject Lines and Send Times
🗓️ Wednesday 26th November 2025
⏰ 3:00 - 4:00 PM GMT
🗣️ Preetham Kaukuntla, Staff Data Scientist @ Glassdoor

Email campaign success through obtaining high engagement numbers has become harder for platforms with diverse user bases who operate at large scale. Traditional standardized email methods to deliver marketing content fall short because there are too many messages combined with brief viewer attention. Joint usage of personalized subject lines with optimized send timing functions as primary methods to gain user engagement thus leading to better open rates and substantive user interactions. The study establishes a complete data-based system which employs behavioral analytics, machine learning models together with A/B testing for dynamic personalization of subject lines and customized send schedules on an individual basis. The proposed system does that by utilizing historical user data, engagement patterns and contextual signals to send highly targeted, timely email contents to dramatically improve user engagement, increases the click through rates and conversion rate from email. Instead of having to sit down and think of a project strategy, the way this approach works is that personalization can be automated at scale as well as through continuous learning and optimization using real-time feedback loops and adaptive algorithms to provide a scalable solution for today’s modern email marketing challenges.
