An agent providing an information retrieval service may work with a corpus of text documents. The documents in the corpus may contain annotations such as Subjective Content Descriptions (SCD) -- additional data associated with different sentences of the documents. Each SCD is associated with multiple sentences of the corpus and has relations among each other. The agent uses the SCDs to create its answers in response to queries supplied by users. However, the SCD the agent uses might reflect the subjective perspective of another user. Hence, answers may be considered faulty by an agent's user, because the SCDs may not exactly match the perceptions of an agent's user. A naive and very costly approach would be to ask each user to completely create all the SCD themselves. To use existing knowledge, this paper presents ReFrESH, an approach for Relation-preserving Feedback-reliant Enhancement of SCDs by Humans. An agent's user can give feedback about faulty answers to the agent. This feedback is then used by ReFrESH to update the SCDs incrementally. However, human feedback is not always unambiguous. Therefore, this paper additionally presents an approach to decide how to incorporate the feedback and when to update the SCDs. Altogether, SCDs can be updated with human feedback, allowing users to create even more specific SCDs for their needs.

MikeRoweWorks Foundation CEO Mike Rowe discusses a surge in white-collar job layoffs and responds to Elon Musk's comments on working from home. Generative artificial intelligence systems are already making it easier for scammers to con elderly Americans out of their money, and several senators are asking the Biden administration to step in and protect people from this quickly emerging threat. Sen. Mike Braun, R-Ind., the top Republican on the Senate Special Committee on Aging, spearheaded a bipartisan letter to the Federal Trade Commission (FTC) on Thursday that asks for an update on what the agency knows about AI-drive scams against the elderly and what it is doing to protect people. The letter, signed by every member of the Senate committee from both parties, asks about AI-powered technology that can be used to replicate people's voices. The letter to FTC Chairwoman Lina Khan warned that voice clones and chatbots are allowing scammers to trick the elderly into making them believe they are talking to a relative or close friend, which leaves them vulnerable to theft.

Microsoft announced a mysterious AI event for March 16th, and it looks like we're getting a big ChatGPT upgrade this week in the form of GPT-4, which comes with multimodal support. That might mean nothing to most people, given that ChatGPT stormed the tech landscape just three months ago, and we're still learning what it can do and how it can disrupt tech as we know it. A multimodal ChatGPT chatbot is a massive upgrade for AI that already provides human-like responses to your queries. Currently, ChatGPT only supports text input or one mode of interaction. GPT-4 will support text, audio, video, and images as input. That's what makes it multimodal, a feature that could significantly increase the AI's capabilities.

Microsoft is set to launch GPT-4, a language model that will be an update to GPT-3.5, the technology used by Open AI's ChatGPT. GPT stands for Generative Pre-trained Transformer, an artificial intelligence algorithm programmed to write like a human. Executives from Microsoft Germany announced that they would introduce GPT-4 within a week, and that it will offer a lot of new possibilities, such as the use of videos. There had already been speculations that the new version would be able to generate images aside from text from the same interface. Models that make use of text, images, and video are called multimodal, and it is possible that GPT 4 will be exactly that.

A Microsoft executive has revealed OpenAI is planning on releasing its upgraded model that powers AI tools such as ChatGPT and Microsoft's Bing Chat. The news comes from Microsoft Germany's Chief Technology Officer (CTO) Andreas Braun, who appeared on stage at the AI in Focus - Digital Kickoff event on March 9 alongside other Microsoft Germany employees. All of the Microsoft officials discussed the upcoming ventures with artificial intelligence language models and the involvement of OpenAI's GPT series. Reports now indicate that OpenAI, in which Microsoft has heavily invested with more than $10 billion already pledged, is nearing the end of development for GPT-4, the next upgrade in the underlying technology powering the now immensely popular AI tools. According to Baum, OpenAI will be rolling out GPT-4 sometime "next week", which means we can expect some kind of announcement from OpenAI this week since Baum made those comments on March 9. "We will introduce GPT-4 next week, there we will have multimodal models that will offer completely different possibilities - for example videos," Braun said.

ChatGPT, the revolutionary chatbot powered by artificial intelligence (AI), will soon be able to do much more than send human-like text messages. A Microsoft executive has revealed that the next version - set to be released this week - will be able to turn text prompts into unique videos. The tech giant has invested heavily in ChatGPT, and has already unveiled a host of new products which incorporate it as an AI assistant, like search engine Bing. But this updated version, dubbed GPT-4 and tipped to launch on Thursday, will have'multimodal models', according to Microsoft Germany CTO Andreas Braun. This means that it will be able to generate content in multiple formats, like audio clips, images and video clips, from a text prompt.

Excitement is building in the artificial intelligence (AI) community as Microsoft Germany's CTO, Andreas Braun, recently announced that GPT-4 will be introduced next week. GPT-4 is the fourth generation of the groundbreaking large language model (LLM) series, which enables machines to understand natural language, a skill previously unique to humans. According to Braun, GPT-4 will offer new possibilities, such as video processing, as well as multimodality, making the models comprehensive. The announcement was made during an AI in Focus – Digital Kickoff event that took place in Germany, attended by news outlet Heise. During the event, Marianne Janik, CEO of Microsoft Germany, emphasized the value creation potential of AI and spoke of a turning point in time – the current AI development and GPT-4 were "an iPhone moment."

ChatGPT has been inescapable in recent months, and it looks like Microsoft is about to upgrade the AI tool with an update that could thrust it into the spotlight once again. That's because the company is set to launch GPT-4 as early as next week, and it will potentially let you create AI-generated videos from simple text prompts. The news was revealed by Andreas Braun, Chief Technology Officer at Microsoft Germany, at a recent event titled "AI in Focus -- Digital Kickoff" (via Heise). According to Braun, "We will introduce GPT-4 next week … we will have multimodal models that will offer completely different possibilities -- for example videos." GPT-4 is the underlying large language model technology that powers apps like ChatGPT.

GPT-4 is coming next week: at an approximately one-hour hybrid information event entitled "AI in Focus - Digital Kickoff" on 9 March 2023, four Microsoft Germany employees presented Large Language Models (LLM) like GPT series as a disruptive force for companies and their Azure-OpenAI offering in detail. The kickoff event took place in the German language, news outlet Heise was present. Rather casually, Andreas Braun, CTO Microsoft Germany and Lead Data & AI STU, mentioned what he said was the imminent release of GPT-4. The fact that Microsoft is fine-tuning multimodality with OpenAI should no longer have been a secret since the release of Kosmos-1 at the beginning of March. "We will introduce GPT-4 next week, there we will have multimodal models that will offer completely different possibilities – for example videos," Braun said.

Springs are efficient in storing and returning elastic potential energy but are unable to hold the energy they store in the absence of an external load. Lockable springs use clutches to hold elastic potential energy in the absence of an external load, but have not yet been widely adopted in applications, partly because clutches introduce design complexity, reduce energy efficiency, and typically do not afford high fidelity control over the energy stored by the spring. Here, we present the design of a novel lockable compression spring that uses a small capstan clutch to passively lock a mechanical spring. The capstan clutch can lock over 1000 N force at any arbitrary deflection, unlock the spring in less than 10 ms with a control force less than 1 % of the maximal spring force, and provide an 80 % energy storage and return efficiency (comparable to a highly efficient electric motor operated at constant nominal speed). By retaining the form factor of a regular spring while providing high-fidelity locking capability even under large spring forces, the proposed design could facilitate the development of energy-efficient spring-based actuators and robots.
