This video introduces the self-supervised representation learning and why we need it. It also discusses the entire pipeline of performing the self-supervised Learning (Learning form unlabeled data). This is the part-1 of the video. The link for part-2 is — https://www.youtube.com/watch?v=j-RSaXzwIHw
Deep Learning systems can achieve remarkable, even super-human performance through supervised learning on large, labeled datasets. However, there are two problems: First, collecting ever more labeled data is expensive in both time and money. Second, these deep neural networks will be high performers on their task, but cannot easily generalize to other, related tasks, or they need large amounts of data to do so. In this blog post, Yann LeCun and Ishan Misra of Facebook AI Research (FAIR) describe the current state of Self-Supervised Learning (SSL) and argue that it is the next step in the development of AI that uses fewer labels and can transfer knowledge faster than current systems. They suggest as a promising direction to build non-contrastive latent-variable predictive models, like VAEs, but ones that also provide high-quality latent representations for downstream tasks.

Women constitute a mere 22 per cent or less than a quarter of professionals in the field of AI and Data Science.
There is a troubling and persistent absence of women when it comes to the field of artificial intelligence and data science. Women constitute a mere 22 per cent or less than a quarter of professionals in this field, as says the report “Where are the women? Mapping the gender job gap in AI,” from The Turing Institute. Yet, despite low participation and obstacles, women are breaking the silos and setting an example for players out in the field of AI.
To honour their commitment and work done, we have listed some of the women innovators and researchers who have worked tirelessly and contributed significantly to the field of AI and data science. The list below is provided in no particular order.

The Seoul Metropolitan Government (SMG) is the first local government in Korea to establish a metaverse platform, which has emerged as a contactless communication channel in the post-pandemic era, to start providing a new-concept public service by using the platform in its administration.
The SMG plans to establish “Metaverse Seoul” (tentatively named), a high-performance platform, by the end of next year, and create a metaverse ecosystem for all areas of its municipal administration, such as economic, cultural, tourism, educational and civic service, in three stages from next year.
Starting with the pilot program of a Bosingak Belfry virtual bell ringing event at the end of this year, the SMG will consecutively provide various business support facilities and services, including the Virtual Mayor’s Office, Seoul FinTech Lab, Invest Seoul and Seoul Campus Town, on its metaverse platform.
Sensors introduce an important new method to spot bio-marker for brain diseases Accurate timings of when brain signals fire demonstrated for the first time by the Sussex scientists, which has implications for tracking the onset of brain disease The quantum brain sensors could present a more efficient and accurate alternative to EEG and fMRI scanners.
It may seem that Facebook took an early plunge into the metaverse, but the virtual world has been in the making for quite some time.

Scientists have been able to trap antimatter particles using a combination of electric and magnetic fields. Antiprotons have been stored for over a year, while antimatter electrons have been stored for shorter periods of time, due to their lower mass. In 2011, researchers at CERN announced that they had stored antihydrogen for over 1,000 seconds.
While scientists have been able to store and manipulate small quantities of antimatter, they have not been able to answer why antimatter is so rare in the universe. According to Einstein’s famous equation E = mc2, energy should convert into matter and antimatter in equal quantities. And, immediately after the Big Bang, there was a lot of energy. Accordingly, we should see as much antimatter as matter in our universe, and yet we don’t. This is a pressing unsolved mystery of modern physics.

Sushil Reddy is no stranger to long-distance electric bicycles rides, having broken the Guinness World Record back in 2016 with a 7,424 km (4,613 mile) ride across India. Since then he’s set his sights on solar power, performing several more long-distance solar-powered electric bike rides. Now he’s halfway through a 10,460 km (6,500 mile) ride around the US on a custom-built solar-powered electric bike as part of the SunPedal Ride project.
As the SunPedal Ride project explained:
“The SunPedal Ride is an outreach project started by Sushil Reddy in 2016. The idea is to have conversations about clean energy and sustainable mobility via endurance journeys undertaken on zero tail-pipe emission vehicles. Each edition of The SunPedal Ride is a new challenge which is executed by a team and supported by a group of sponsors/partners to spread the message via public interactions. A medium of a zero tail-pipe emissions vehicle is used in each edition of The SunPedal Ride.”
November 27, 2021 — A few years ago, a little known Montreal XR company was putting its patented technical chops into building out what many think is the “last interface”, one that Facebook (ahem, Meta’s) CEO Mark Zuckerberg is betting the social media giant’s future on. Today, that Montreal company, and some pretty impressive Canadian innovators, find themselves thick in the middle of the Metaverse’s battle of the titans.
