DAIS Virtual Challenge 2026: Weather-Aware Event Recommendation & Safety Advisory using Databricks

cielle_stcl — Sun, 31 May 2026 15:05:59 GMT

I'm exploring an idea that combines event discovery, weather intelligence, and safety awareness into a single AI-powered experience built on Databricks.

The Problem

When people travel or plan activities, they often face three common challenges:

Activities are not always weather-suitable: eg hiking during heavy rain periods
Event information is difficult to discover due to printed brochures. As a result low attendance rate.
Safety advisories are often unstructured eg: avoid waterfall visits during rainy season.

These messages are rarely centralized and are difficult for visitors to discover.

Proposed Solution

Build a Databricks-powered application that recommends activities based on:

Destination country/location
Visiting date
Weather forecast
Event availability
Safety advisories

The system can provide recommendations such as:

✅ Outdoor activities when weather is favorable

⚠️ Alternative indoor activities during poor weather

🚫 Safety warnings for activities that may pose risks under certain conditions

Technical Approach

Using Databricks as the unified platform:

Data Sources

Structured Data

Event catalog
Event schedules
Location information

Semi-Structured Data

Weather forecast APIs

Unstructured Data

Tourism brochures
Activity descriptions
Safety notices
Travel advisories

AI Agents

Event Recommendation Agent (used gpt-4 model)

Uses weather forecasts
Retrieves events and activities (applied rag with FAISS vector store + conversational memory to understand the unstructured data content)
Considers safety advisories
Produces weather-aware recommendations

Poster Generation Agent (used gpt-image-1 model)

Creates marketing posters
Generates event promotion content
Improves visibility for local activities

Databricks Components

Lakehouse architecture for unified data storage
Databricks Apps for web and chat interfaces
Databricks Volumes for brochure and document storage
Open LLMs hosted within Databricks
API integrations for weather forecasts

Example User Experience

User Prompt

"I'm visiting Japan in November with my family. What activities do you recommend?"

AI Response

Recommended seasonal events
Weather outlook
Outdoor suitability score
Indoor alternatives
Safety advisories
Suggested itinerary
Poster with associated detail for marketing posting

Looking forward to hearing your thoughts and suggestions.
