Developing models to forecast the class or category of a specific instance based on its characteristics, such as determining whether a client would leave, constitutes the strategy of classification. Identifying patterns of co-occurrence between variables, such as which products are frequently bought together, is done using the association rule mining technique. Anomaly detection is a method for spotting unusual occurrences or patterns in data that don't match the expected pattern, like spotting fraudulent transactions. Using the clustering technique, similar instances are grouped together based on shared characteristics, for example, customers with similar purchasing habits. Regression analysis is a method for simulating the relationship between a dependent variable and one or more independent variables. For instance, it can be used to forecast a house's price based on its size and location. Data Mining Methods: The Top Five - DMNews

Big data can be used to target specific people with customised messaging in order to influence public opinion and political results. Economic inequality: The growing usage of big data and AI technologies has the potential to make things worse by giving those who have access to them new opportunities while lagging behind those who do not. Using big data to send personalised messages to specific individuals might polarise society by reaffirming pre-existing beliefs and splitting people into smaller and smaller groupings.

Big data frequently involves the gathering, storing, and processing of substantial volumes of personal data, which raises questions about privacy and the potential for misuse of sensitive data. Discrimination: If the data used to create the algorithms only reflects a limited range of experiences or results, big data algorithms may continue to be biassed and discriminatory. Discriminatory consequences and judgements, such as unfair credit or job decisions, may result from this. Job loss: Big data analytics and artificial intelligence (AI) technologies have the potential to replace human labour and cause job losses by automating a variety of functions.

Despite being a potent tool, predictive analytics has a number of disadvantages that may affect the accuracy and value of predictions: Prediction accuracy is significantly impacted by the quality of the data used in predictive modelling. Predictions may be inaccurate or misleading if the data is inconsistent, incomplete, or wrong. Model bias: Predictive models are prone to bias if the data used to build the model only represents a limited range of events or outcomes. This may make it harder for the model to correctly forecast results for novel, untested data. Overfitting is when a predictive model is too closely matched to the training set of data and struggles to generalise to brand-new, untried data. This may result in unreliable model performance and inaccurate predictions. Limited data: In order to create effective models using predictive analytics, a substantial amount of data is required. The model might not be able to identify significant patterns or relationships in the...

Storage: Big data requires the capacity to manage and store massive volumes of data, which often entails the usage of distributed storage systems like Hadoop HDFS or NoSQL databases.

  Lack of alignment within teams There is a lack of coordination across multiple teams or divisions within an organisation. A select group of executives may be granted access to data analysis produced by a selected set of team members. However, the insights generated by these teams are of minimal value and have little impact on organisational measurements. This might be due to teams working in "silos," each with its own processes and separated from other departments. The analytics team should focus on giving right answers to the business's inquiries, and data analytics team results should be successfully conveyed to the relevant employees in order to inspire the suitable course of action and behaviour that will benefit the organisation.   Lack of commitment and patience Analytics solutions are not difficult to implement; yet, they are costly, and the ROI is slow. It may take some time to establish standards and processes in order to begin collecting data, especial...
