By applying state-of-the-art biomedical computer vision techniques, we predict a patient’s body orientation in CT scans. This means that incorrect metadata that was manually entered by a technician can be automatically identified and corrected to ensure patient records are as accurate as possible to improve diagnosis.

Medica Image Classification

AI for Wildlife and Marine Conservation

  • New data acquisition technologies such as drones, remote sensing, motion-sensor cameras, and citizen science apps provide vast opportunities to help scientists analyze wildlife species and their ecosystems.

  • This enormous amount of data can play a significant role in wildlife research and conservation by automating image processing so that scientists can more easily detect, identify, and count wildlife in their natural environments.

  • AI can help address important problems including classifying images to understand the distribution of species, mapping resources and vegetation types, tracking the spread of diseases, predicting extreme weather events, assessing the impact of climate change, and protecting wildlife from poachers.

  • These smart applications will greatly assist conservation practitioners by automating time-consuming processes with faster, cheaper, and self-learning systems that enable them to focus on other challenging tasks.

  • AI applications such as fine-grained image recognition can help scientists automatically emit different labels that are associated with millions of different species and then assigns image tags.

  • Previously, this manual task would rely on thousands of volunteers and hours to categorize photographs by species and behavior.

  • Researchers can analyze larger data sets more efficiently with computer vision to identify individual animals of endangered species while reducing fieldwork and image processing time.

 

 

Solution

 

In this case study, we process images from the Serengeti National Park and classify a zebra and the top categories identified in the photograph. Once an image is assigned with the correct tags, researchers can perform other advanced analyses to inform conservation policy.

Object Detection – Remote Sensing Multispectral Satellite Imagery

 
  • Using modern cameras and advances in AI, new and unexplored territories of object detection applications can now be explored.

  • We can now define where things and people are in the real world, in real time and take action to improve safety and well-being.

  • Say you looked at a picture of different objects in a scene, you could immediately detect the classes and understand where in the image the objects are located using object detection.

  • Object detection could be applied to various business applications such as satellite imagery to study earth materials, detect hidden objects, and support natural hazard and disaster recovery.

Some of the ways we can sort through the remotely sensed data with AI to derive insights that people can use:

  • For instance, we might want to identify ports and understand shipping logistics to analyze economic trends and impacts on global trade.

  • In agriculture, we can identify what crop types are being grown in specific areas to better understand crop health and climate change impacts and optimize energy or water usage in those areas to maximize production.

  • During natural hazard and disaster events (earthquakes, wildfires, volcanoes, landslides, hurricanes, and floods), space imagery gives us a unique perspective of situational awareness to help deploy rescue teams and aid, and monitors things globally.

  • National security teams can analyze satellite imagery to identify undisclosed operating bases and construction activity.

  • Land use classification and detection with satellite imagery can provide socioeconomic indicators that help predict poverty and wealth in specific locations around the world. 

  • AI can improve our ability to track developments such as roads, urban areas, waterways, farmland, and electricity to help organizations allocate funds and create more effective policies.

Solution

Additionally, we also demonstrate a satellite image land use and land cover multi-label classification system. 

Image Segmentation for Scene Understanding

 
  • Rapid advances in computer vision are enabling brand new applications to be built that were impossible just a few years ago.

  • Image segmentation is a key component of image processing and computer vision applications such as autonomous driving, motion capture, and surveillance systems.

  • These segmentation models allow us to precisely classify every part of an image at an object instance level where the pixels of each individual object is located.

  • The applications of image segmentation at a pixel by pixel level are far-reaching and can be used to segment various types of complex objects and backgrounds for scene understanding.

  • Computer vision is now helping self-driving cars figure out where are the other cars and the pedestrians around it so it avoids them.

  • Image segmentation is also assisting medical practitioners with automatic analysis of 3-D radiological images.

  • Here we demonstrate how we use computer vision software to detect and segment objects such as humans, vehicles, road signs, wildlife, and also categorize each of these segments with a unique color.

 

Sports Video Analysis and Tracking

  • With advances in modern communication and the internet, video has become one of the most common sources of visual information.

  • This vast amount of video data available online would take humans several years to watch all the videos available across various platforms.

Customer Sentiment Classification Marketing and Retention

  • Creative use of advanced Natural Language Processing techniques can be an effective tool to develop desirable goods and services, anticipate customer desires, respond to customer problems, and stay ahead of competitors. 

  • Using NLP, we can build applications that can extract key phrases to determine important points and topics, extract semantic meaning, and understand sentiment or intent from textual data.

  • With the recent advances in deep learning, the ability to analyze social media information, customer reviews on a website, email messages, or any message where it's important that we get a sense of the sentiment behind the text has improved considerably with human-level accuracy.

  • Techniques such as sentiment analysis and intent analysis are very important tools for analyzing textual data because it allows for segmentation by attitude, and could identify whether it relates to an opinion, news, marketing, complaint, suggestion, appreciation or query.

Intent Classification

Intent analysis steps up the game by analyzing the user’s intention behind a message and identifying whether it relates an opinion, news, marketing, complaint, suggestion, appreciation or query.

  • Our society is rapidly evolving with respect to innovative technology, trade, business, and media.

  • We now have the internet and various forms of communication platforms that we consume to conduct business, stay aware of daily events, connect with the world, and communicate with our loved ones.

  • These advancements are generating huge amounts of text and unstructured data that need to be quickly analyzed to extract valuable insights.

  • This produces a significant challenge in business because the presence of excess data or information becomes difficult to process in making well-informed decisions, and humans have short attention spans when consuming large text documents and articles.

  • However, AI can be applied to perform automated text summarization to shorten huge documents into a summary that captures the key concepts and meaning of the original document for consumers and clients.

  • Some common approaches for building automated text summarizers and information extraction systems include extraction and abstraction-based techniques such as natural language generation (NLG), ranking models, topic models, and key phrase extraction.

  • The core concept behind all these applications is to find a representative subset of the original dataset that retains the semantic and conceptual points to generate actionable insights.

Document Summarization

  • In this case study will demonstrate a simple implementation of document summarization to solve the challenge of information overload.

  • We will show from the outputs that we successfully summarized our document into a shorter summary that depicts the core essence of the document, and also supports keyword extraction.

Machine Translation with Attention

  • One of the most significant language processing applications that plays a central role in our multilingual information society is neural machine translation.

  • The goal of this model is to build an end-to-end network that can read in a sentence then output a translation directly.

  • This technique can help with providing syntactic, grammatical, and semantically correct translation between any two pairs of languages such as English to French.

  • Modern sequence-to-sequence models use encoder and decoder architecture to encode a source sentence into a fixed-length vector from which a decoder generates the respective translation.

  • These AI systems provide enormous social, government, and commercial value by providing more natural human-machine translation interfaces, and access to valuable stored information.

  • More significantly, this is a very powerful way to bring people together from different languages, different countries, and enable them to improve communication and collaboration.

Neural Machine Translation Workflow

  • Input Text 

  • Encoder-Decoder

  • Translated Text

In this case study, we demonstrate how we can use neural machine translation to submit some input text in one language and have it instantly translated to another language of our choice.

  • With the wealth of AI capabilities that are now rapidly becoming available, businesses are engaging their customers in new transformative ways with conversational agents called chatbots.

  • Using state-of-the-art machine learning, chatbots can hold contextual conversations with users, perceive vast amounts of information, and respond intelligently using speech or text.

  • These AI agents are being used in customer service, advertising, and marketing to deliver more customized experiences.

  • Chatbots can also act as a personal assistant to help answer your questions, automate your home, book reservations, order food, or purchase an item.

  • Most importantly, chatbots can support and scale business operations, increase customer satisfaction, boost brand value, save time and money, automate repetitive tasks, and become personal assistants.

Speech Recognition & Synthesis

Speech Recognition & Synthesis

  • Speaking and writing are two of the most common forms of human communication in our everyday life products such as telephones, computers, radio and television, video games, audio players, and mobile devices.

  • As a result, vast amounts of data important to several industry domains are being stored in the form of written documents and recorded speech.

  • The ability to convert this spoken and handwritten data into digital texts or audio can lead people to interact more naturally with computers.

  • With recent advances in automatic speech recognition, computers can now understand speech and text, create dialogues with humans in natural ways, and complete actions and tasks on behalf of users through automatic speech recognition and speech synthesis.

  • Automatic speech recognition refers to the task of transcribing audio into text, while speech synthesizers generate artificial speech by converting normal language text into audio.

  • Increasingly, AI systems enable humans to communicate with software and hardware services through speech recognition.

  • These techniques are enabling successful applications and automation in customer care systems, smart speakers, speech translation, spoken document retrieval, voice recognition, performing authentication, assisting the disabled, and conversational AI.

  • Speech recognition applications are also transforming various industries by reducing business costs, automating complex processes, and increasing overall efficiency.

Conversational AI with Speech Recognition & Natural Language Understanding (NLU)

  • Increasingly, we expect chatbots and smart machines to be able to use AI in order to understand spoken or typed commands in natural language and speech.

  • To make this possible, we need to apply speech-to-text transcription to generate text from user commands and text-to-speech to convert the system responses back into audio.

  • Now to work with speech, we have to recognize that there are two models that need to work together.

  • First of all, there's an acoustic model that matches audio to sound units or phonemes, which define how specific word fragments are pronounced in a given language.

  • Then there's a language model that provides a probability distribution across a sequence of words.

  • In order for computers to be able to interpret user input, modern AI systems combine speech and language understanding technologies such as domain classification, intent classification, and semantic slot filling to enable humans to communicate with software services.

AI-powered Home Automation Using Speech Recognition and Natural Language Understanding

In this use case, we use intelligent voice-activated control to say ”Turn on the light" or ”Put the light on", and have an AI-powered device understand the spoken command and take appropriate action.

Natural Language Processing

Natural Language Processing

  • As humans, having the ability to communicate naturally through written and spoken language is key to successful collaboration.

  • Natural Language Processing (NLP) allows us to build deep learning algorithms to solve critical tasks that can process text and speech to enable AI for language and communication. For example, NLP applications can help us understand text, extract semantic representations, embed neural knowledge graphs, determine important points and topics, analyze sentiment, generate text, and even speak and engage in conversations with AI agents.

  • Our modern NLP methods will enable you to automatically search, retrieve, and analyze textual data using efficient pre-processing tools, computational linguistics, topic models, embeddings for similarity analysis, text categorization, text visualization, transformers, and deep learning models.

  • We use highly sophisticated multimodal vision and language joint learning and inference applications including natural language understanding, machine translation, semantics and the syntactic parsing, continuous word representation, automatic summarization, natural language emulation, dialectal systems, image captioning and visual question answering, information retrieval, semantic parsing, dialect systems, entity ranking, Chatbots, knowledge graphs, and deep reinforcement relevance networks.

  • Our NLP workflow will guide you through the process of analyzing your raw textual data using a combination of efficient preprocessing tools, computational linguistics, topic models, distributional semantic word representations, semantic similarity analysis, text classification, text generation, visualizations, transformer architecture, and NLP deep learning models.

Continuous Word Representations

 
  • Traditional methods like one-hot encoding can be considered as a kind of high dimensional embedding but they provide no useful information to the natural language processing (NLP) systems regarding the relationships that may exist between the individual vectors.

  • In the case of word embeddings, it can benefit a lot of different NLP tasks by mapping words or phrases to vectors of real numbers to a lower dimensional space, then assign the semantic meaning to this representation.

  • This new lower dimensional vector space also places words that are semantically similar or relevant to each other close to each other in this semantic space.

  • Additionally, word embeddings can be used for a variety of text processing tasks such as feature extraction and language modeling.  

Continuous word representations are useful for several NLP problems such as preprocessing, semantic representations, text classification, recommendation systems, machine translation, spoken dialogue systems, synonyms and search query expansion, question answering, and more.

In this task, we assign the semantic meaning to this representation and compute the semantic representation.

 

Some continuous word representations include:

WordRank, FastText, Multi-Relational LSA, RDA, CBOW/Skip-gram, RNN-LM, SENNA, DSSM, GloVe, Word2Vec, Doc2Vec, Item2Vec, Brown Clustering, VarEmbed etc.

Other Techniques:

  • Word Algebra, t-SNE

  • Automatic Phrase Modeling

Topic Modeling

  • As more massive collections of electronic text become available to us, automatically extracting valuable information from this unstructured data is incredibly valuable for consumers.

  • To maximize this hidden value, software needs to be able to create structure, summarize text, extract relationships and semantic meaning, and even sentiment information from the language we use as humans.

  • Topic Modeling is an information retrieval and extraction technique to systematically organize, understand, and discover topics in large collections of text documents.

  • It can help us discover document-level themes in large textual data, annotate documents with the learned topics, and support a variety of subsequent NLP tasks including organizing, searching, understanding, visualizing, predicting, and summarizing unstructured information.

  • This suite of tools can be used to help explore, summarize, and perform predictions across many domains including images, music, networks, genomics, and neuroscience.

Some applications:

 

Topic correlation, Document clustering, Document deduplication, Document analysis, Dynamic Topic modeling, Author Topic modeling, Collaborative Topic modeling, and Topic Networks etc.

 
 

Sentiment Analysis

 

Suppose you want to build an NLP system to examine millions of online product reviews and automatically tell you if the customer liked or disliked a specific product or service.

 

For example, you hope to classify the following review as highly positive:

 

"This is a great elliptical machine and I use it every day!"

 

And the following as highly negative:

 

"This bike is low quality--I regret buying it."

 

The problem of recognizing positive vs. negative opinions is “sentiment classification.”

Sentiment classification is a technique that we can use to analyze text and try to discern whether the text indicates that the writer is happy or unhappy or perhaps neutral about something.

 

Automatic Text Summarization

 
 

Natural Language Understanding

  • Natural Language Understanding (NLU) is a task to interpret conversational speech or text to perform a series of tasks based on the user's request.

  • Designed to identify valuable information in conversations, language understanding uses machine learning to detect user intents and entities from sentences to integrate natural language understanding into apps, bots, and IoT devices.

  • Using advanced dialogue management based on machine learning, you can build smart bots and digital assistants that can handle multi-turn, contextual conversations like Siri, Cortana, or Google Assistant.

Applications:

 

Domain Classification, Intent Recognition, Semantic Slot Filling.

 

AI Bots and Digital Assistants for your industry

 

Customer Service Chatbot (NLU)

  • AI bots are capable of human-level speech and comprehension.

  • They can communicate with humans, understand needs, and help with tasks that boost our quality of life and global productivity.

Embed AI bots into web applications and mobile devices.

 

Image Captioning

  • Humans learn to interact with the world using a combination of natural language, images, sequences, and knowledge jointly.

  • This multimodal learning helps us acquire information from diverse sources and learn to be smart and perform intelligent tasks.

  • So for building machine intelligence, we also hope the machine can learn from multiple sources and perform intelligent tasks across multiple modalities.

  • One example of multimodal learning is image captioning, where an AI system generates a caption for an image.

  • Another example is phase to image, where NLP and Computer Vision techniques can be combined to go from a sentence to an image.

  • By building machine intelligence to understand images deeper, we can describe objects, attributes, and relationships in a more natural way to communicate with humans.

Several benefits can be obtained by people who would benefit from automated insights from photos or videos.

Some examples include:

  • Automatically generating text and extracting insights from a broad range of visual concepts.

  • Serving as an assistance tool for handicapped and visually impaired individuals.

  • Explaining and understanding what happens in a video in real-time.

  • Supporting a variety of autonomous devices and applications.
