Image classification involves training a machine learning model to classify images based on their contents. For example, in a traffic monitoring solution you might use an image classification model to classify images based on the type of vehicle they contain, such as taxis, buses, cyclists, and so on.
Object detection machine learning models are trained to classify individual objects within an image, and identify their location with a bounding box. For example, a traffic monitoring solution might use object detection to identify the location of different classes of vehicle.
Semantic segmentation is an advanced machine learning technique in which individual pixels in the image are classified according to the object to which they belong. For example, a traffic monitoring solution might overlay traffic images with “mask” layers to highlight different vehicles using specific colors.
You can create solutions that combine machine learning models with advanced image analysis techniques to extract information from images, including “tags” that could help catalog the image or even descriptive captions that summarize the scene shown in the image.
|Face detection, analysis, and recognition
Face detection is a specialized form of object detection that locates human faces in an image. This can be combined with classification and facial geometry analysis techniques to recognize individuals based on their facial features.
|Optical character recognition (OCR)
Optical character recognition is a technique used to detect and read text in images. You can use OCR to read text in photographs (for example, road signs or store fronts) or to extract information from scanned documents such as letters, invoices, or forms.
Understand natural language processing
Natural language processing (NLP) is a subfield of artificial intelligence that deals with the interaction between computers and humans in natural language. It involves processing natural language datasets, such as text corpora or speech corpora, using either rule-based or probabilistic (i.e. statistical and, most recently, neural network-based) machine learning approaches. The goal is a computer capable of “understanding” the contents of documents, including the contextual nuances of the language within them. The technology can then accurately extract information and insights contained in the documents as well as categorize and organize the documents themselves.
NLP has a wide range of applications, including:
- Sentiment Analysis: Identifying the sentiment of a piece of text, such as whether it is positive, negative, or neutral.
- Named Entity Recognition: Identifying and categorizing named entities in text, such as people, organizations, and locations.
- Machine Translation: Automatically translating text from one language to another.
- Question Answering: Automatically answering questions posed in natural language.
- Chatbots: Interacting with users in natural language to answer questions or perform tasks.
NLP is a rapidly evolving field, with new techniques and models being developed all the time. Some of the most recent advances include:
- Pre-trained Language Models: Large neural network models that are trained on massive amounts of text data, allowing them to perform a wide range of NLP tasks with high accuracy.
- Transformers: A type of neural network architecture that has revolutionized NLP by allowing models to process entire sequences of text at once, rather than one word at a time.
- Zero-shot Learning: A technique that allows models to perform NLP tasks in languages they have never seen before, by leveraging their knowledge of related languages.
NLP is a powerful tool that has the potential to transform the way we interact with computers and with each other. As the field continues to evolve, we can expect to see even more exciting applications of this technology in the years to come.
Document Intelligence is a subfield of AI that focuses on managing, processing, and utilizing large volumes of data found in forms and documents. It enables the creation of software that can automate processing for contracts, health documents, financial forms, and more. This technology can extract valuable information from unstructured data sources, categorize and organize documents, and efficiently manage high volumes of data. Knowledge Mining is another area of AI that deals with extracting information from large volumes of often unstructured data to create a searchable knowledge store. It is a powerful tool that can help organizations extract valuable insights from their data and make informed decisions. Together, Document Intelligence and Knowledge Mining are transforming the way businesses manage and process data, enabling them to work more efficiently and effectively.
Generative AI is a subfield of artificial intelligence that deals with creating original content. It is often used in chat applications, where it takes in natural language input and returns appropriate responses in a variety of formats, including natural language, image, code, and audio. Generative AI models learn the patterns and structure of their input training data and then generate new data that has similar characteristics. This technology has a wide range of applications, including art, writing, script writing, software development, product design, healthcare, finance, gaming, marketing, and fashion. With the advent of large neural network models and transformer-based deep neural networks, generative AI has become more powerful and capable of performing a wide range of tasks with high accuracy.
Responsible AI is an approach to developing, assessing, and deploying AI systems in a safe, trustworthy, and ethical way. It emphasizes accountability, fairness, and inclusivity. The goal is to ensure that AI is created and applied in an ethical way that benefits everyone, while minimizing the potential for artificial intelligence to cause harm. Responsible AI practices aim to mitigate bias, ensure privacy, and prioritize the well-being of all users. Microsoft Azure provides a suite of tools to help you create a customized, end-to-end responsible AI experience, including the Responsible AI Dashboard, which offers a range of tools to help you operationalize responsible AI practices for your organization or business.
