The Crucial Role of Data Scientists in AI Integration: A Guide to Maintaining the Data Science Lifecycle
When AI-naive organizations rush to incorporate AI into their workflows without following the data science lifecycle, they often end up with predictions that lack alignment with domain experts.
Why does AI have minimal business impact at AI-naive enterprises? This article emphasizes the need for organizations to retain the data science lifecycle in their AI endeavors and highlights the pivotal role of a senior data scientist in guiding the process.
In the rapidly evolving landscape of artificial intelligence (AI), organizations are often eager to leverage its potential without fully understanding the intricacies involved. A common pitfall is the inclination to opt for software as a service or vendor solutions, bypassing the crucial data science lifecycle. This approach, however, may lead to predictions and classifications that fail to integrate seamlessly with domain experts' workflows, ultimately yielding minimal business impact.
The key to successful AI integration lies in embracing the data science lifecycle and enlisting the expertise of a seasoned data scientist to lead the exploration. While there is a growing trend towards data scientist-less AI solutions, it is essential to recognize their limitations in addressing complex problems encountered by domain experts.
The initial step in this process involves meeting with domain experts and closely observing their workflows. Mapping these workflows in a flowchart provides a visual representation, especially useful when dealing with enterprise-level challenges that exhibit horizontal dependencies with various stakeholders. These dependencies with stakeholders can be mapped out in a mindmap. The collaboration between the data scientist and domain expert becomes an iterative process, leading to a final flowchart that serves as a model for the expert system and workflows.
Once the mindmap and flowcharts are established, attention turns to the associated data. Ideally, labeled data provided by domain experts facilitates the exploratory data analysis (EDA) phase. In cases where such labeled data is unavailable, assisting domain experts in proper labeling becomes important. However, unsupervised and/or semi-supervised (if some labeled data available) techniques can commence while the labeling process is set up.
The analytics journey unfolds through different phases, aligning with the data science lifecycle:
Descriptive Analytics (What happened?): This phase involves delving into historical data, performing descriptive statistics, and trend analysis. It is a critical part of EDA, uncovering low-hanging fruit that sets the foundation for subsequent analyses.
Diagnostic Analytics (Why did it happen?): During EDA, patterns in the data begin to emerge, leading to the identification of correlations between variables. Collaboration with domain experts validates hypotheses through hypothesis testing, exploring causality to understand the 'whys.'
Predictive Analytics (What will happen?): Armed with insights from EDA and hypothesis testing, organizations can start predicting future events and outcomes, providing a forward-looking perspective.
Prescriptive Analytics (How can we make it happen or prevent it?): Building on predictive analytics, prescriptive analytics enables organizations to make proactive recommendations. Collaborating with domain experts, plans can be formulated to either encourage or prevent forecasted events.
The outlined analytics phases underscore the importance of the data scientist's involvement throughout the data science lifecycle. This partnership with domain experts is crucial for extracting value from analytics, progressing from hindsight (descriptive) to insight (diagnostic and predictive) and finally to foresight (prescriptive). In essence, maintaining the integrity of the data science lifecycle ensures that AI initiatives are not only technologically sound but also deeply ingrained in the real-world workflows of domain experts, leading to impactful and sustainable outcomes.
