- Audience insight - describe audience composition and characteristics
- Adhoc analysis - support business request to better understand our data assets when data is not readily available from our BI tools
- Support sales pitch - provided valuable extra insight to augment the value proposition for key accounts

**Research and Development**:
Our Data Science role includes the following responsibilities:

- Research and development of cutting edge Machine Learning systems, models, and schemes in many different areas of Adtech
- Develop real-time algorithms for audience creation and segmentation
- Discover insights/patterns in our customers from various data sources such as exchange data, behavioural data, location data, 1 and 3rd party data assets
- Design experiments, oversee A/B testing, evaluate the quality of derived assets and continuously monitor model performance
- Create proof of concepts and data science prototypes
- Search and select appropriate data sets
- Perform statistical analysis and use results to improve models
- Identify differences in data distribution that could affect model performance in real-world situations
- Visualize data for deeper insights
- Analyze the use cases of ML algorithms and ranking them by their success probability
- Understanding when your findings can be applied to business decisions
- Reducing business problems into Machine Learning problems and opportunities
- Verifying data quality

**Collaborative Work**:

- Work closely with product, engineering, and sales teams to drive the use of Data Science across the Verve Group
