                     Based on Data Format
                     Data format refers to how the data is stored, such as numbers, text, images or time-series data.
                     Datasets can be classified as follows:

                                 Numerical datasets: A numerical dataset consists of data in the form of numbers, such
                                   as statistics, measurements or financial figures, which are used for calculations and
                                   quantitative analysis.

                                 Text datasets: A text dataset contains written or spoken language data, such as
                                   articles, emails or social media posts and is mainly used in natural language processing
                                   tasks.

                                 Multimedia datasets: A multimedia dataset includes a combination of different
                                   types of data such as images, audio and video and is commonly used in applications
                                   like speech recognition and video analysis.

                                 Time-Series datasets: A time-series dataset is made up of data points collected
                                   over a period of time, such as stock prices or weather records and is used to analyse
                                   trends and make future predictions.

                                 Spatial datasets: A spatial dataset contains information related to geographical
                                   locations, such as maps or satellite data and is used in applications like navigation
                                   and geographic analysis.

                                 Image  datasets: An image  dataset  consists  of collections  of pictures  or visual
                                   data that are used in computer vision tasks such as object detection and image
                                   classification.

                                 Web datasets: A web dataset is gathered from online sources like websites, blogs
                                   and web pages. It is used for tasks such as search engines, recommendation systems
                                   and web analytics.

                      Collect a few Multimedia datasets (images, sounds or videos) from the internet. How do technologies
                      like facial recognition (images) or speech recognition (audio) use this data to understand and process
                      human input? Create a simple poster to show how AI can see and hear.
