Business analytics involves using various technologies to analyze data. Data mining focuses on the automated search for knowledge, patterns, or regularities in data. As a business analyst, it is essential to recognize the type of analytical technique appropriate for solving a specific problem. Exploratory Data Analysis (EDA) describes data using statistical and visualization techniques to highlight important aspects of that data for further analysis. This involves examining a data set from many angles, describing it, and summarizing it without making assumptions about its content. Exploratory data analysis is an essential step before diving into statistical modeling or machine learning to ensure that the data is really what it claims to be and that there are no apparent errors. This type of analysis should be part of data science projects in every organization. Visual analytics is sometimes confused with data visualization. Visual analysis is not simply a matter of graphically representing data. Modern, interactive visual analytics makes combining data from multiple sources easy and performs in-depth data analysis directly in the visualization. Additionally, artificial intelligence and machine learning algorithms can offer recommendations for exploration. Ultimately, visual analytics helps transform massive data sets into business insights that can positively impact an organization. Considering the previous comment about visual data analysis, it should be added that the system has extensive capabilities to create graphical dashboards containing reports and charts. It is essential that in the case of desktops, in addition to the visualizations included in the system itself, it is possible to embed reports from third-party tools.

The human face hides many secrets and is one of the most expressive human features. Human faces even contain hidden information about a person's personality. Considering the fundamental role of the human face, it is necessary to prepare appropriate deep-learning solutions that analyze human face data. This technology is becoming increasingly common in many industries, such as online retail, advertising testing, virtual makeovers, etc. For example, facial analysis technology now allows online shoppers to virtually apply makeup and try on jewelry or new glasses to get an accurate picture of what these products will look like. The human sense of hearing is a treasure trove of information about the current environment and the location and properties of sound-producing objects. For instance, we effortlessly absorb the sounds of birds singing outside the window, traffic passing in the distance, or the lyrics of a song on the radio. The human auditory system can process the intricate mix of sounds reaching our ears and create high-level abstractions of the environment by analyzing and grouping measured sensory signals. The process of obtaining segregation and identifying sources of a received complex acoustic signal, known as sound scene analysis, is a domain where the power of deep learning shines. The machine implementation of this functionality (separation and classification of sound sources) is pivotal in applications such as speech recognition in noise, automatic music transcription, searching and retrieving multimedia data, or recognizing emotions in statements.
