What are Predictive Analytics?

Forecasting is a branch of advanced research that predicts future outcomes using historical data combined with statistical modeling, data mining techniques, and machine learning. Companies use predictive analytics to find patterns in this data to identify risks and opportunities. Predictive analytics is often associated with big data and data science. Today's business is full of data ranging from log files to images and videos, and all of this data resides in different databases within the organization. To gain insight from this data, data scientists use deep learning and machine learning algorithms to find patterns and predict future events. Some of these statistical techniques include linear and logistic regression models, neural networks, and decision trees. Some of these modeling techniques use prior predictive learning to obtain additional predictive information. A type of predictive model

Predictive analytics are designed to analyze historical data, identify trends, observe trends, and use this information to predict future events. Popular forecast analysis models include classification, summation, and chronological models.

 Classification type

Classification models fall under the branch of supervised machine learning models. These models organize data based on historical data, describing relationships within a given data set. For example, this model can be used to divide customers or prospects into groups for segmentation purposes. On the other hand, it can also be used to answer questions with binary numbers, such as answering yes or no or true and false; The most common use cases are fraud detection and credit risk analysis. Types of classification include logistic regression, decision trees, forests, neural networks, and Naïve Bayes.

Collection type

Cluster models fall under unsupervised learning. They aggregate data based on similar characteristics. For example, an e-commerce site can use a model to separate customers into similar groups based on common characteristics and develop marketing strategies for each group. Common statistical algorithms include k-means clustering, random variable clustering, spatial clustering based on density of noisy applications (DBSCAN), expectation-maximizing clustering (EM) using Gaussian mixture models (GMM) and rank clustering.

Time series

Time series models use different data inputs at the same time, such as daily, weekly, monthly, etc. It is common practice to report changes based on time to analyze data about time, conditions, and cyclical behavior, which may indicate the need for specific models and changes. Autoregressive (AR), moving average (MA), ARMA, and ARIMA models are the most commonly used time series models. For example, a call center can use a schedule system to estimate the number of calls it will receive per hour at different times of the day.
