How does machine learning work?

Machine learning works by Building ‘smart algorithms’ and present the computer with ‘enough’ real-world examples of the environment (training data), so that when the computer sees ‘similar data’, it knows what to do.
In order to stay at the top, machine learning models need to be trained on representative datasets that include all the needed all possible circumstances and possibilities
Some examples:
  • Traffic cameras that automatically detect lane violations.
  • Fitness applications that automatically log your calorie count from pictures of the food you eat. You don’t have to input the amount and type of food anymore.
  • Security cameras that annotate the root cause of motion sensor triggers (e.g. whether it was an animal, human, falling leaves, a car driving by, etc.) and react accordingly. It also helps decrease the frequency of false alarms.
For these Computer Vision models to work in real world with best accuracy, curated (labeled) data sets are used by ML experts to train algorithms by adjusting parameters, in order to make accurate predictions for incoming data.




What is text annotation in machine learning? Explain with examples.

Text Annotation is the practice and the result of adding a note or gloss to a text, which may include highlights or underlining, comments, footnotes, tags, and links.
Text annotations helps machines to recognize the crucial words in sentence making it more meaningful.
We at PBS data labeling services provide services of annotating text for NLP in machine learning through text annotation services making the written words recognizable and understandable to machines.

Why do we annotate images?

  For a computer to understand images, the training data needs to be labeled and presented in a language that the computer would eventually ...
