Salesforce’s AI navigates Wikipedia to find answers to complex questions

Wikipedia offers a wealth of knowledge on countless topics to those who know where to look, but therein lies the rub — navigating its database of over 6 billion articles requires some web-crawling finesse. In an effort to streamline the search, researchers at Salesforce developed what they call a graph-based trainable retriever-reader framework, which sequentially […]

Microsoft’s CodeBERT ingests public GitHub repositories to help you find code

Large pretrained language models have improved the state-of-the-art on a range of natural language processing tasks, chiefly because they’re able to learn contextual representations from text without supervision. In a preprint paper, a team of researchers at Microsoft Research Asia used this to their advantage to create a system — CodeBERT — for programming languages […]

Facebook’s AI speeds up natural language processing without additional training

Natural language models typically have to solve two tough problems: Mapping sentence prefixes to fixed-sized representations and using the representations to predict the next word in the text. In a recent paper, researchers at Facebook AI Research assert that the first problem — the mapping problem — might be easier than the prediction problem, a […]

Untrue News indexes and flags false and misleading news articles

According to Statista, as of March 2018, around 52% of Americans felt that online news websites regularly reported fake stories in the U.S., with another 34% stating they believed news websites occasionally reported fake stories. Those sentiments aside, sussing out the sources of empirically untrue news online isn’t easy. But a team of researchers from […]

Microsoft’s AI improves text summarization performance by paying closer attention to the beginning

A newsy feature from the New York Times is bound to read differently than the average Reddit post. Indeed, the diversity of writing styles and grammatical structures makes the task of automatic text summarization highly challenging. That’s why researchers from Pittsburgh and Microsoft Researcher’s Future Social Experiences (FUSE) lab, which focuses on real-time and media-rich […]

Amazon researchers distill knowledge from a large AI model to a simplified version

In AI and machine learning systems, knowledge is typically distilled by training a small model — a student — to mimic a large and cumbersome model — a teacher. The idea is to compress the teacher’s knowledge by using its outputs as labels to optimize the student, but there’s no guarantee knowledge will be transferred […]

Amazon researchers improve Alexa’s ability to parse commands

Voice assistants like Amazon’s Alexa, Apple’s Siri, and Google Assistant often rely on a semantic parsing component to understand which actions to execute for a spoken command. Traditionally, rule-based or statistical slot-filling systems have been used to parse simple queries — that is, queries containing a single action — and more recently, shift-reduce parsers have […]

Amazon Polly’s Brand Voices taps AI to generate custom spokespeople

If Amazon has its way, companies will soon tap Amazon Web Services (AWS) en masse to create voices tailored to their brands. The Seattle tech giant today launched Brand Voices, a fully managed service within Amazon Polly, Amazon’s cloud service that converts text into lifelike speech, that pairs customers with Amazon engineers to build AI-generated […]

Voice cloning experts cover crime, positive use cases, and safeguards

Deepfakes, or media that takes a person in an existing image, audio recording, or video and replaces them with someone else’s likeness using AI, are multiplying quickly. In recognition of the threat that deepfakes pose to privacy, civility, and democratic processes, the U.S. Federal Trade Commission (FTC) hosted a workshop yesterday examining a subcategory of […]

AISense raises $10 million for AI transcription tool Otter

There’s plenty in the way of competition with respect to the audio transcription market, which is estimated to be worth $31.82 billion by 2025. But AISense — the startup behind speech-to-text service Otter — managed to carve out a niche for itself in the four years since its founding. Its funding reflects this — the […]

LinkedIn is using AI to spot and remove inappropriate user accounts

Social networks including Facebook, Twitter, and Pinterest tap AI and machine learning systems to detect and remove abusive content, as does LinkedIn. The Microsoft-owned platform — which has over 660 million users, 303 million of whom are active monthly — today detailed its approach to handling profiles containing inappropriate content, which ranges from profanity to […]

Google’s AI language model Reformer can process the entirety of novels

Whether it’s language, music, speech, or video, sequential data isn’t easy for AI and machine learning models to comprehend — particularly when it depends on extensive surrounding context. For instance, if a person or an object disappears from view in a video only to reappear much later, many algorithms will forget how it looked. Researchers […]
