Traditionally when organizations have looked at AI and machine learning, data has been treated as a static artifact while the bulk of organization’s focus has been on the model. This model-centric AI approach — keeping the data fixed and iterating over the model and its parameters to improve performances. Model centric AI involves collecting and cleaning large volumes of data and using this data to run algorithmic models. As the name suggests, this approach emphasizes on the model rather than the data and the model needs to be constantly experimented with for better results.
Model centric AI, however, approaches present a set of problems. For example, not every organization has the capability or expertise to collect and process large volumes of data, the required technology can be costly, and the security concerns associated with vast data quantities becomes a compliance issue. Furthermore, multiple and different models may be in use within the same organization, leading to data inaccuracies and disagreements on which model to use.
However, the more recent trend of data-centric AI underscores the role of data and data quality in AI based applications. Data-centric AI focuses on collecting high quality data from the beginning in a way the data that will deliver the best results. Having higher quality data helps to improve the model too. Adopting a data-centric approach will help you overcome some of the challenges posed by model-centric AI:
- As the data that is collected is first cleansed, organizations will be able to access high quality, standardized and accurate data
- As teams do not necessarily have to experiment with models, your development processes become less time consuming. This will help with faster development of applications.
- Deciding on the exact types of data needed prior to commencing projects will enable consensus building, as this will be useful for determining the best model to adopt.
