    Instagram Posts can Tell how Sane you are – A New Research Reveals

    Instagram Posts can Tell how Sane you are – A New Research Reveals

    A picture speaks a thousand words and telling the state of your mental health may be one of them – when you post them on Instagram. This is according to a recent study published on the EPJ Data science website. The research was conducted by Andrew G Reece, a postdoctoral researcher at Harvard University and Christopher M Danforth, a professor at the University of Vermont.

    The research applied on 166 carefully selected ‘special’ cases, classified them as “depressed” or “healthy” based on whether they reported having received a clinical diagnosis of depression in their history. They used machine-learning tools to detect patterns in submitted photos and to create a model that could predict depression by the posts.

    Out of the 166 individuals selected, 71 had a history of depression. The researchers used software to analyze each photo’s hue, colour saturation and brightness, as well as the number of faces it contained. They also collected information about the number of posts per user and the number of comments and likes on each post.

    Reseach Data

    “Using Instagram data from 166 individuals we applied machine learning tools to successfully identify markers of depression. Statistical features were computationally extracted from 43,950 participant Instagram photos, using colour analysis, metadata components, and algorithmic face detection. Resulting models outperformed general practitioners’ average unassisted diagnostic success rate for depression. These results held even when the analysis was restricted to posts made before depressed individuals were first diagnosed. Human ratings of photo attributes (happy, sad, etc.) were weaker predictors of depression and were uncorrelated with computationally-generated features. These results suggest new avenues for early screening and detection of mental illness.” – the article’s excerpt read.Instagram Posts can Tell how Sane you are

    The research discovered that individuals with a history of clinical depression used fewer Instagram filters – which allows individuals modify the brightness and hue of pictures before posting. When these ‘depressed’ participants used a filter, they favoured “Inkwell” which in fact drains pictures of its colour, making it black-and-white. ‘Healthy’ participants on the other-hand tended to prefer “Valencia”, which lightens tint.

    “People in our sample who were depressed tended to post photos that, on a pixel-by-pixel basis, were bluer, darker and greyer on average than healthy people,” – the report stated.

    Another indicator was the appearance of faces in photos posted; “depressed” participants had a greater tendency to put up photos with a face, although the “healthy” posted photos with faces as well, they, in fact, have posts with more faces when they post such.

    “This is only a few hundred people, and they’re pretty special,” Mr Danforth said of the study participants. “There’s a sieve we sent them through depressed participants had a greater tendency to put up photos with a face.”

    Instagram Posts can Tell how Sane you are 2How participants were chosen

    To be included in the study, participants had to meet several criteria. They had to be active and highly rated on Amazon’s Mechanical Turk platform, a paid crowd-sourcing platform that researchers often use to find participants. They also had to be active on Instagram and willing to share their entire posting history with the researchers. Finally, they had to share whether they had received a clinical diagnosis of depression.

    The researchers found out that the more comments a post received, the more likely it was to have been posted by a depressed participant. The opposite was true for likes. And depressed users tended to post more frequently, they found.

    Though they warned that their findings may not apply to all Instagram users, Mr Reece and Mr Danforth argued that the results suggest that a similar machine-learning model could someday prove useful in conducting or augmenting mental health screenings.

    “We reveal a great deal about our behaviour with our activities,” Danforth said, “and we’re a lot more predictable than we’d like to think.

    The study may be opening a new page on the impacts of social media: As revealing as the findings are about Instagram posts specifically, both men said the results speak more to the promise of their techniques.

    For many people, managing money and knowing the ri For many people, managing money and knowing the right opportunities to invest in is still a challenge. A survey of over 2,000 youths in Nigeria, Kenya, Uganda, Tanzania and Cote D’Ivoire by Geopoll revealed that more young Nigerians only save after spending than their counterparts in other countries.

More youths in Tanzania and Uganda set aside a fixed amount to save than in Nigeria and Ivory Coast, who are more likely to save what remains after spending

The popularity of apps like @Piggybankng and @Cowrywise has made more people curious about saving, investing and creating a financial strategy to grow their money. However, there is need for more apps that take a more deliberate and friendly approach towards gaining financial intelligence and map out a sustainable path to monetary stability.

This is where Fundall comes in. @get_Fundall is a fintech service whose app is available for download on android and iOS.

    Things are gradually returning to normal as the nu Things are gradually returning to normal as the number of covid-19 cases continues to fall. Although it may take a while before we hug people or shake hands without second thoughts, things are getting better.

Only 523 new cases were recorded between April 6 and 13. This is a slight increase compared to the 497 people that tested positive over the previous week. Two weeks earlier, Technext reported that 584 people tested positive.

The numbers show a sustained decrease in the spread of infections across the country. Indeed the Lagos state government is now confident enough to allow event centres and relaxation centres to increase their crowd capacity. Along with that, here are other developments during the week.

    Today, @Google unveils a Doodle to posthumously ma Today, @Google unveils a Doodle to posthumously mark the 74th birthday of Nigerian music legend and highlife maestro Oliver de Coque, one of Africa’s most prolific recording artists of all time.

The Doodle, created by Lagos-based graphic artist and illustrator @OhabTBJ, pays tribute to the guitarist who died in June 2008 at the age of 61, following a heart attack. The creative inspiration was drawn from De Coque’s love for the guitar, his energetic performance style, his unique music brand, and his love of tradition and culture.

According to NIBSS Instant Payment stats, the state recorded the largest number of PoS transactions in the country.

The report shows that Lagos accounted for about 70% of the total volume of PoS transactions in 2020. This represents a 100% growth in the volume of PoS transactions in the state as the volume of PoS transactions rose from 226 million in 2019 to over 453 million at the end of 2020.
