For effective content moderation, Facebook is relying on three aspects of technology to transform its content review process across its family of apps.
The first aspect is called ‘Proactive Detection’ where Artificial intelligence (AI) can detect violations across a wide variety of areas without relying on users to report content to Facebook, often with greater accuracy than reports from users.
“This helps us detect harmful content and prevent it from being seen by hundreds or thousands of people,” the company said in a statement.
‘Automation’ is the second aspect where AI systems have automated decisions for certain areas where content is highly likely to be violating.
“Automation also makes it easier to take action on identical reports, so our teams don’t have to spend time reviewing the same things multiple times. These systems have become even more important during the Covid-19 pandemic with a largely remote content review workforce,” said Jeff King, Director Product Management, Integrity at Facebook.
The third aspect is ‘Prioritisation’.
Instead of simply looking at reported content in chronological order, AI prioritises the most critical content to be reviewed, whether it was reported to Facebook or detected by its proactive systems.
“This ranking system prioritizes the content that is most harmful to users based on multiple factors such as virality, severity of harm and likelihood of violation,” Kind added.
However, Facebook admitted there are still areas where it’s critical for people to review the content.
“For example, discerning if someone is the target of bullying can be extremely nuanced and contextual. In addition, AI relies on a large amount of training data from reviews done by our teams in order to identify meaningful patterns of behaviour and find potentially violating content”.
For reviewing violations like spam, Facebook said it is going to use its automated systems first to review more content across all types of violations. (IANS)

Winters in India have always beckoned for that hot, steaming bowl of tomato and pepper rasam or the mellow, millet based Raab. Certain dishes like sarson ka saag, undhiyu, nimona pulao are winter specialites in the country. Seasonal food has always been an Indian speciality -- we switch our choice in fruits, vegetables, sometimes even grains with the onset of different season. The preference of using specific ingredients during certain climates is visible in our sweets as well. It's common to find local and traditional delicacies made of jaggery, instead of sugar during the winters. Case in point -- the Nolen Gur Rasgulla, a speciality made in Odisha and West Bengal between November to February.
Celebrity chef, Sanjeev Kapoor, strongly advocates this need of eating seasonal produce. He says, "The beauty of our food is in our seasonal usage of fruits and vegetables. If you realise, Gajar ka halwa is made aplenty during winters as this is the season when beautiful red carrots hit the market or mango pickle is made during summer, thanks to its availability. Despite people and sometimes, even me, suggesting that we should eat fresh as well as seasonal fruits and vegetables, we do not know what chemicals are sprayed on them to keep them safe while they are growing. When this produce hits the market, there isn't a certifying agency like the FSSAI that will help people understand what vegetables and fruits are free of pesticides and germs and which ones don't. Hence, the onus lies on us to make them safe for consumption. ITC's Nimwash is a good solution."
When it comes to winters, the Chef recommends eating these fruit and vegetables:
* Purple Mogri -- Mogri or Radish pods are not a common sight throughout the country. But you can spot them during the winters in local markets in northern India where women pick them up to make raitas, curries and stir fries. Rich in magnesium, calcium and copper, the vegetable is known to aid people from digestive problems.

* Sweet Potato -- A re-discovered favourite, Sweet potatoes have created a space for itself in the millennial kitchen. With its diverse addition in burgers, chips and even chat, the root vegetable is filled with nutrients such as fibres and vitamins.

* Avarekalu -- Called Hyacinth beans in English, Avarekalu is a winter speciality in the south that is added to sambhar, saagu, rotis, etc. Bangalore is famed for its Averakalu mela during the winter months, where you can find these beans in dosas, Pani puri and even Jalebis! Thronged by crowds from all over the city, the food fest is a gourmand's delight.

* Amla -- The Indian gooseberry is a common winter fruit found through the country. High in Vitamin C, it is known to be immunity building and extremely beneficial for the skin and hair. There are multiple ways to eat Amla -- it is pickled, made into a fruit preserve called as Murraba or even eaten by sprinkling salt over it.

Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight, finds a new study. The study, published in the journal Scientific Reports, found there was, on average, a 17 per cent improvement in participants' colour contrast vision when exposed to three minutes of 670 nanometre (long wavelength) deep red light in the morning and the effects of this single exposure lasted for at least a week.
However, when the same test was conducted in the afternoon, no improvement was seen. "We demonstrate that one single exposure to long wave deep red light in the morning can significantly improve declining vision, which is a major health and wellbeing issue, affecting millions of people globally," said lead author, Glen Jeffery from the University College London.

For the study, the team involved a small yet significant number of participants aged between 34 and 70, had no ocular disease, completed a questionnaire regarding eye health prior to testing, and had normal colour vision (cone function). This was assessed using a 'Chroma Test' -- identifying coloured letters that had very low contrast and appeared increasingly blurred, a process called colour contrast.
Using a provided LED device, all participants were exposed to three minutes of 670nm deep red light in the morning between 8 a.m. and 9 a.m. Their colour vision was then tested again three hours post exposure and 10 of the participants were also tested one week post exposure. On average there was a 'significant' 17 per cent improvement in colour vision, which lasted a week in tested participants; in some older participants, there was a 20 per cent improvement, also lasting a week.
A few months on from the first test (ensuring any positive effects of the deep red light had been 'washed out') few participants, carried out the same test in the afternoon, between 12 p.m. to 1 p.m. When participants then had their colour vision tested again, it showed zero improvement.

As the world reopens after 18-20 months of the Covid-19 pandemic and lockdowns, a new variant of the coronavirus -- called B.1.1.529 -- has been identified in South Africa that has left the scientific community worried, as they fear that this new strain could fuel outbreaks in several countries and cripple health systems once again. Over 100 cases have been detected in South Africa, where the new strain is slowly becoming the dominant one.
Here are five things you should know about this deadly super Covid variant that has forced a number of countries, including the UK, Israel, Italy and Singapore, to restrict travel from South Africa and other countries in the region.
1. According to South African health officials, the 'B.1.1.529' variant has many more mutations than scientists expected, especially after a severe third wave, which was driven by the Delta variant. Many of the mutations are of concern for immune evasion and transmissibility.
2. B.1.1.529 carries a high number of mutations in its spike protein, which plays a key role in the virus' entry into cells in the human body. The B.1.1.529 variant has 50 mutations overall, including more than 30 on the spike protein alone which is the target of most current Covid vaccines.

3. The World Health Organisation (WHO) has said it will take a few weeks to understand the impact of the new variant. Scientists have said it is the most heavily mutated version yet, which means vaccines, which were designed using the original strain from Wuhan in China, may not be as effective. The WHO has called a meeting to discuss B.1.1.529 and decide if it will be officially designated a variant of concern.
4. First identified in South Africa this week, the strain has spread to nearby countries, including Botswana. Israel has identified a case of a Covid-19 variant with a large number of mutations "in a person who returned from Malawi". Two cases have been detected in Hong Kong. India has called for rigorous screening of passengers from South Africa, Botswana, and Hong Kong.
5. There are still speculations floating around the variant's origin. According to Francois Balloux, Director of the London-based UCL Genetics Institute, the new strain "likely evolved during a chronic infection of an immuno-compromised person, possibly in an untreated HIV/AIDS patient".
