The origins...
Predictive analytics has its roots in various fields, including statistics, data mining, and artificial intelligence. The concept of using historical data to predict future outcomes can be traced back to the early 20th century. The early statistical foundations of predictive analytics were laid in the 1940s when regression analysis became a cornerstone of predictive modeling (Fisher, 1922). This was followed by the development of time series analysis methods in the 1950s and 1960s, which provided the groundwork for forecasting techniques (Box & Jenkins, 1970). The term "data mining" gained popularity in the 1990s, encompassing various techniques for extracting patterns from large datasets (Fayyad et al., 1996). During this period, decision trees, neural networks, and other machine learning algorithms began to be applied to business problems, marking the beginning of modern predictive analytics. The evolution of predictive analytics has been largely driven by technological advancements. Increased computing power and storage capabilities in the late 20th and early 21st centuries enabled more complex analyses (Chen et al., 2012). The rise of big data in the 2000s provided vast amounts of information for predictive models, further expanding the field's capabilities (Mayer-Sch?nberger & Cukier, 2013).
In the early 2000s, predictive analytics began to be integrated with business intelligence tools, allowing for more actionable insights (Eckerson, 2007). This integration led to the concept of "analytics 3.0," which combined big data with traditional analytics approaches (Davenport, 2013). The mid-2010s saw a surge in machine learning applications, particularly deep learning, which greatly enhanced predictive capabilities (LeCun et al., 2015). Ensemble methods like Random Forests and Gradient Boosting Machines became popular for their high accuracy and robustness (Breiman, 2001; Friedman, 2001).

L'articolo è bello, tuttavia, aumenta l'amarezza quando in Italia viene dato risalto a lavori "stranieri" e si snobbano lavori itaiani. L'articolo non è attuale, non è aggiornato manca tantissimo, mancano TUTTE le scoperte, le tecnologie e le soluzioni italiane che da tempo vengono impiegate con successo in molti campi che non vedo in elenco. Strano.
