ABOUT PREDICTIVE ANALYTICS

To put it briefly, the concept of predictive analytics revolves around the prediction of future events based on several analytics reports. This is done by utilizing various methods of statistics. Oftentimes, predictions rely on the utilization of modeling techniques as well.

Generally, predictive analytics is done by watching and understanding the current data along with past data. Such data is oftentimes related to certain significant events. The prime aim of observing and analyzing the data is to check whether such events would likely happen in the near future. This understanding would help you to prepare and anticipate accordingly.
This system of predictive analytics is useful for investors who require a regular understanding of the organization’s operational efficiencies. Furthermore, such data is utilized by key stakeholders/ investors in the reduction of risk. To know more, you can check out the Best Machine Learning Course.

There are several uses of predictive analytics as follows.

PREDICTIVE ANALYTICS: USES

-MARKETING

The new-age marketing depends heavily on crafting and launching the perfect campaign. Oftentimes, the campaigns are relied on for gaining customers and to get reasonable ad conversions. The percentile of ad conversion success relies on the reach of the campaign. More specifically, the success relies on the positive response of customers to the ad. But, how will your organization know or “predict” the respective consumer/ customer’s reaction? This is where predictive analytics comes in handy. While generating any campaign, the predictive analytics report data will be looked at beforehand. This report would indicate the ways in which your target audience has reacted to a similar type of campaign in the past. Based on this understanding, you can easily predict the reaction of your campaign. This prediction can be applied in entirely different demographics too. This prediction is very helpful in customizing the products based on the possible purchase percentile.

In addition to mainstream marketing, traders oftentimes look into predictive analytics for a variety of reasons. This includes purchasing/ selling their security.

– CREDIT SCORES

Have you ever heard of someone stating that their recent purchase has affected their credit score?

Well, in simple terms, credit scores influence the percentile of credit you can benefit from the bank.

It would be right to state that a credit score can be viewed as a report of your spending behavior using your credit card. When banks see the report, they would authorize/ decline your loan application based on the report.

Credit scores are calculated via the predictive analytics method. This method would indicate to the banks whether the loan sanctioned would be paid back properly or not. In simple terms, the rate of risk will be “predicted” through the analytics methods.

-FORECAST

The third popular usage of predictive analytics is forecasting in the manufacturing sector. Forecasting is implemented in the manufacturing sector for ensuring the optimal usage of resources. For, only the optimal use of supply chain resources would give the best results in the manufacturing sector. Furthermore, aspects such as inventory management, and shop management highly rely on predictive analytics reports to function perfectly.

In addition to management, predictive analytics models are important in data quality optimization. This data cleaning enhances the accuracy of prediction.

There are several important terms relevant to understanding predictive analytics more clearly. The following segment will elucidate the same. To know more, check out Machine Learning Tutorial.

KEY TERMS

– FEATURE VECTOR

In simple terms, the feature vector can be known as the feature of predictive analytics. These features are influential in the decision-making processes.

– PERFORMANCE EVALUATION AND CROSS-VALIDATION MATRIX

This is a crucial aspect in the division of the dataset. The percentile of distribution varies from one organization to another. The best division ratio arrangement is said to be 80:20. The 70:30 ratio works equally well too.

This matrix is helpful in testing the performance of data on several types of evaluation matrixes. Usually, this process follows after the training of the data model. It is important to note that along with several other important evaluation matrixes, ROC/AUC curves and confusion matrices are popular choices across the organizations.

– TRAINING DATA

Speaking of training data in the above segment, training data could be said as one of the most important ingredients in predictive analytics. To understand training data, it is important to understand machine learning algorithms. Machine learning algorithms, in simple terms, rely heavily on past activities/ experiences to produce reports/results. Such past activities and experiences are known as training data. It is more accurate to state that training data indeed forms the core aspect of any predictive analytics framework.

Following the basic understanding of predictive analytics, it is now time to understand the life-cycle of the predictive analytics system.

PREDICTIVE ANALYTICS LIFECYCLE

Predictive analytics are divided and subdivided into several phases. However, the phases have the following common aspects.

– DISCOVERY OF DATA

This is oftentimes the very first step in the predictive analytics life cycle. In this step, you will figure the usage of the data/ outcome. In brief, you will decide the future goals and acquire data accordingly. This step is also inclusive of the creation of hypotheses, understanding of data in general, and more of such nature.

– PREPARATION OF DATA

Following the understanding of the goals, the collected data will be prepared, accumulated, and adequately cleansed. For the preparation of data, several modes and methods of data collection are relied on. This is inclusive of the accumulation of information (oftentimes from external sources), formulation of data, and capturing of information. Data formulation uses digital. manual methods for the process. Furthermore, information is captured from digital devices in general.

– DESIGNING OF MODEL

Only a properly designed model ensures the reaching of the goal. Several techniques such as ETL, ELT, and ETLT are implemented to make the best predictive analytics data model. Oftentimes, this phase is utilized in the determination of what to do in the subsequent phases.

– BUILDING OF MODEL

This phase involves the development of data for the aspects of production, training, and testing. The successful execution of data relies on a number of techniques. This involves decision trees, logistic regression, and more of similar nature. Trial runs are done in this phase to ensure the best results.

Following this phase, the best version of the model is shown to the respective stakeholders. This would be subsequently followed by a great deal of discussion to determine whether the project is a success or not.

Following the discussion, the final report is submitted to the relevant stakeholders.

CONCLUSION

Predictive analytics rely highly on the quality of data. With the growing role of predictive analytics in organizations across the globe, it is important to ensure that the quality of the data is greatly improved by each passing day.
