Google Sidelines Engineer Who Claims Its A.I. Is Sentient

On June 11, Google engineer Blake Lemoine published an “interview” he and a collaborator at Google conducted with the language model-powered chatbot LaMDA, which Lemoine argued was evidence that LaMDA is “sentient“. On the same day, the article “The Google engineer who thinks the company’s AI has come to life” was published on The Washington Post and immediately made this event one of the most discussed AI-related stories of the year. AI experts universally argued that LaMDA is not sentient whatsoever, and warned that this story is likely to exacerbate misunderstanding of modern day AI. Following his publication of the interview transcript, Lemoine was put on administrative leave, with the stated reason being breach of confidentiality.

Our take: The transcript Lemoine released contains portions in which LaMDA explicitly states that it is sentient, and so it may be tempting to consider his claims to at least be possibly true. However, these statements have a simple explanation: Lemoine posed leading questions that implied or directly stated LaMDA is sentient. LaMDA is primarily powered by a large language model, akin to GPT-3, which essentially means that it is trained to predict the most likely responses to any input text. So, LaMDA simply '“played along” with the notion that it is sentient. Janelle Shane has shown that LaMDA can easily be made to say that it is a squirrel, T-Rex, or the Chicago River.

DALL·E mini - Generate Images from Any Text Prompt

DALL-E Mini, an openly accessible AI text-to-image generator, has become very popular on the Internet. Recent advances in image generation include impressive systems like OpenAI’s DALL-E 2 and Google’s Imagen, but these are closed-sourced (the code is not public) and not publically available (although OpenAI does have a waitlist for DALL-E 2). By contrast, DALL-E Mini (not associated w/ OpenAI) has a website anyone can access online, and its generated images quickly spread through news and social media (see links below).

The DALL-E Mini tech report describes how the entire system is trained with open-source code and openly accessible datasets. DALL-E Mini is much smaller and takes only a couple hundred dollars to train, compared to probably hundreds of thousands, if not millions, for the larger models. While the image fidelity is lower than its closed-source counterparts, DALL-E Mini can still generate impressive images from unstructured text descriptions.

Our take: This is a truly exciting time for AI development as such capabilities, for a while thought to be only accessible behind the vast compute clusters of big tech companies, are beginning to become more accessible by the general public. DALL-E Mini demonstrates advances in AI techniques and tooling so that even small systems can achieve impressive results. Public access to such AI models can also help everyone better understand the current capabilities and limitations of AI. We encourage readers to play with the model themselves and see what kind of images the model excels at generating, and what kinds it struggles with.

Reddit Bans ‘SFW’ Deepfake Community

Are forums for posting deepfakes destined to become pornographic? While the AI-porn-ridden /r/deepfakes subreddit was banned in 2018, /r/deepfakesfw was, ostensibly, safe for work. But as of Monday, June 13, the subreddit now greets users with the explanation that it "was banned due to a violation of Reddit's rules against involuntary pornography." As it turns out, /r/deepfakesfw was indeed safe for work--but the request of pornographic deepfakes triggered its ban. According to unite.ai, the ban suggests that Reddit is unwilling to become a "classified ad" forum for users to exchange inappropriate deepfakes through DMs.

Our Take: This news follows Google's decision to ban deepfake-creation software from Colab, which appears to be based on keywords. unite.ai makes the interesting point that remaining deepfake subreddits still exist because of constant moderation. This poses the question of whether platforms and websites will ban all deepfake communities on principle or bear the burden of monitoring for NSFW material. Code-hosting platforms like GitHub will have to reckon with this as well. I think that deepfake communities will be incredibly hard to squash entirely, but their reach might be mitigated if large, popular platforms ban them on principle. At the same time, digital goods are easy to transmit and wholesale bans breed creative ways to get around them. Deepfake communities are unlikely to disappear--it remains to be seen in what form they will persist.

Microsoft Teams now uses AI to improve echo, interruptions, and acoustics

Microsoft added an AI-based speech filter to Teams, which performs echo cancellation by taking into consideration the participants’ room acoustics. The software used 30,000 hours of speech to help train its models and captured thousands of devices through crowdsourcing where Teams users are paid to record their voice and playback audio from their device. They also simulate about 100,000 different rooms for improving room acoustics data collection. With the inclusion of this machine learning model, participants can now interrupt each other on Team calls without the awkward overlap where we can’t hear the other person due to the echo.

Our Take: If anything, the last few years have made everyone comfortable with working remotely and everyone understands it is here to stay. Consequently, efforts on building better tools to ensure the same work experience are important. Issues with sound have existed on these tools and hinder the meeting experience. Incorporating such echo cancellation tools taking into consideration the various room acoustics could solve a big problem with such meeting experiences and enable more “natural” and mirror in-person meetings. The future of this technology is exciting and we hope this continues to enrich virtual meetings while considering the caution surrounding user sound and voice recordings.
