• Sensors: Data can also be collected from various sensors like collecting environmental data and stored in some
data storage solutions. Sensors are connected through gateways which enable them to collect live data in the
offline mode.
• Cameras: Data can be seen, written down or recorded on the computer. Cameras are used to collect data in
the form of images. CCTV, web cameras, and surveillance cameras are big sources of visual data that can be
acquired from various places.
• Observations: It is a method of collecting data by watching facts as they occur. Using the observation technique,
data can be analysed and used for testing the model.
• Application Programming Interfaces (APIs): APIs are a set of functions and procedures that allow one
application to connect to another. So, one of the ways of collecting data is through APIs that can be used to
collect data from social media services for analysis.
There are times when, using the internet, we acquire unauthentic data from websites for our AI project.
Extracting private data can be an offence. So, keeping this in mind we should ensure the data is collected from
open-sourced websites hosted by the government. They are one of the most reliable and authentic sources of
information. These portals have information collected in a suitable format that can be downloaded. Some of the
open-sourced government portals are data.gov.in, india.gov.in, etc.
After listing the data features, let's understand the concept of system maps.
Reboot
List down 5 ways of acquiring data for an AI project.
System Maps
A system map is a diagrammatic representation of a set of things working together. It focuses on the components
and boundaries of a system. System map helps us to find relationships between different elements of the problem
which we have scoped. It helps to find a solution to achieve the goal of our project. Let us understand system maps
with the help of an example.
Streets are safe for pedestrians to walk if the number of people driving on the roads are less.
If the number of vehicles on the road increases, –
the emission levels also increase.
We use system maps to understand the complex
issues that have inter-connected factors affecting – +
each other. A system comprises: Driving Safe Streets Walking
• Elements: These are different, discrete elements
within the system.
+
• Interconnections: These are the relationships
that connect the elements.
Rules for system maps are as follows: Emissions
• The circles represent elements.
