Predictive Analytics: Forecasting Future Trends

 What is Predictive Analytics?

Predictive analytics is the process of discovering interesting and meaningful patterns in data. It uses several related disciplines, including pattern recognition, statistics, machine learning, artificial intelligence, and data mining, which have been used to discover patterns in data for over 100 years.

What differentiates predictive analytics from other types of analytics?

First, predictive analytics is data-driven, meaning that algorithms derive key characteristics of the models from the data itself rather than from assumptions made by the analyst. Put another way, data-driven algorithms induce models from the data. The induction process can include the identification of variables to be included in the model, parameters that define the model, weights or coefficients in the model, or model complexity.

Second, predictive analytics algorithms automate the process of finding patterns in the data. Powerful inductive algorithms not only determine the model’s coefficients or weights but also the actual shape of the model. For example, decision tree algorithms learn which of the possible inputs best predict the target variable, and then identify which values ​​of the variables to use to make the prediction. Other algorithms can be modified to perform a search using an exhaustive or greedy search to find the optimal set of inputs and model parameters. A variable is incorporated if it helps reduce the model error. Overview of Predictive Analytics in the model.

 Otherwise, if the variable does not help to reduce model error, it is eliminated. Another automated task available in many software packages and algorithms automates the process of transforming input variables so they can be effectively used in predictive models. For example, if there are a hundred variables that are candidate inputs to models that can be or should be transformed to remove skew, you can do this with some predictive analytics software in a single step rather than programming all one hundred transformations one at a time.

Supervised vs. Unsupervised Learning:

 Algorithms for predictive modeling are often divided into two groups: supervised learning methods and unsupervised learning methods.

supervised learning models / predictive modeling:

In supervised learning models, the supervisor is the target variable, a column in the data representing values to predict from other columns in the data. The target variable is chosen to represent the answer to a question the organization would like to answer or a value unknown at the time the model is used that would help in decisions. Sometimes supervised learning is also called predictive modeling. The primary predictive modeling algorithms are classification for categorical target variables or regression for continuous target variables.

Unsupervised learning / descriptive modeling:

Unsupervised learning, sometimes called descriptive modeling, has no target variable. The inputs are analyzed and grouped or clustered based on the proximity of input values to one another. Each group or cluster is given a label to indicate which group a record belongs to.

Parametric vs. Non-Parametric Models:

 Algorithms for predictive analytics include both parametric and non-parametric algorithms.

Parametric algorithms:

Parametric algorithms (or models) assume known distributions in the data. Many parametric algorithms and statistical tests, although not all, assume normal distributions and find linear relationships in the data. Machine learning algorithms typically do not assume distributions and therefore are considered non-parametric or distribution-free models.

The advantage of parametric models:

 The advantage of parametric models is that if the distributions are known, extensive properties of the data are also known, and therefore algorithms can be proven to have very Certain properties related to error, convergence, and safety of the learned coefficients. However, because of such assumptions, analysts often spend a lot of time transforming data to realize these benefits.

Non-parametric models:

Non-parametric models are far more flexible because they do not have underlying assumptions about the distribution of the data, saving the analyst considerable time in preparing data. However, far less is known about the data a priori, and therefore non-parametric algorithms are typically iterative, without any guarantee that the best or optimal solution has been found.

 

Benefits of Predictive Analytics :

Predictive analytics helps companies make more informed decisions. Identifying patterns and trends in data allows various business functions to make probabilistic decisions about future events. Other benefits include:

Decision-making: Improves decision-making for business functions by determining potential outcomes based on data.

Risk management: Develops risk management strategies for potential risks and prioritizes the most harmful risks.

Customer insights: Gain a deeper understanding of potential customers and their needs, allowing you to develop more targeted marketing campaigns to reach them.

Operational efficiency: Makes business operations more efficient by leveraging historical data to understand and better manage resources.

Challenges in Using Predictive Analytics:

 Predictive analytics has the potential to lead to significant improvements in efficiency, decision-making, and return on investment. However, it is not always successful, and more often than not, the majority of predictive analytics models never see operational use. Some of the most common reasons predictive models don’t succeed can be grouped into four categories:

1) obstacles in management

2) obstacles with data

3) obstacles with modeling

4) obstacles in deployment
