The researchers, Bingbing Ni of the Advanced Digital Sciences Center in Singapore, along with Zheng Song and Shuicheng Yan from the National University of Singapore, have published their study in a recent issue of IEEE Transactions on Multimedia. To begin, the researchers developed an automatic web image and video mining scheme, in which they used age-related search queries to collect nearly 400,000 images from popular image search engines such as Flickr and Google Images as well as 10,000 YouTube video clips. The face images were tagged with ages, and were used to develop a novel learning algorithm for training the system. Although the faces in the video clips were not tagged with ages, the researchers could still use them for training, as they provided the same face at different angles and different lighting conditions.Although there have been several other computerized human age estimators, this system has by far the largest database of facial images compared to the others: after poor-quality images and false alarms were removed, the database contained 77,000 images containing 219,000 faces. In addition, unlike some of the previous smaller databases, the images in this database included faces of people from different racial groups, and had different illumination conditions and different qualities. This diversity gave the system a “universal” capability.A demo video on intelligent advertising using the universal human age estimator. Video credit: Bingbing Ni, et al.“The greatest significance is that, using web-based mining, there is no need to manually construct a face image database, which is quite labor-intensive and costly,” Ni told PhysOrg.com. “And the automatically mined web image database possesses the generalization capability, e.g., models trained on this data can be applied to general faces.”For general image qualities, the model could estimate a person’s age to within an average range of ±5 years. In the future, the researchers hope to further improve the system by minimizing errors, particularly for mediocre image qualities.A computer that can estimate a person’s age, regardless of race or image quality, could have a variety of applications, such as for demographic data collection in supermarkets and other public areas, age-specific human-computer interfaces, and human identification based on old ID photos. Another use, as Ni explains, is age-oriented commercial advertisements.“For example, digital signage applications – installed in shopping malls, vending machines, etc., automatically estimate the customers’ ages and recommend corresponding product advertisements,” he said. (PhysOrg.com) — As humans, we have a knack for estimating another person’s age quite accurately just by glancing at their face. Although age estimation may seem relatively simple to us, computers have a much more difficult time performing the task. In one of the latest attempts to build a computer that can accurately estimate a person’s age, researchers have taken a bottom-up approach to the challenge, collecting hundreds of thousands of images and videos from the Internet to train the system. Their goal is to build a universal human age estimator that is applicable to all ethnic groups and various image qualities.last_img read more

Botanists suggest Voynich illustrations similar to plants in Mexico

first_img New study suggests Voynich text is not a hoax More information: A Preliminary Analysis of the Botany, Zoology, and Mineralogy of the Voynich Manuscript, HerbalGram, 2013: cms.herbalgram.org/herbalgram/ … 00-feat-voynich.html Explore further (Phys.org) —A pair of botanists has published a paper in HerbalGram in which they note similarities between plant illustrations in the famed Voynich Manuscript and plant illustrations in old Mexican botanical books and suggest it might mean the Vonyich Manuscript has New World origins. Credit: HerbalGram The Voynich Manuscript is a text (found in 1912 in an Italian monastery by book dealer Wilfred Voynich) believed to have been written in the 15th century (carbon dated to a time between 1404 and 1438) by an unknown author. It’s attracted notice because it’s written in a language that no one has ever been able to decipher despite over a century of trying. Making things even more interesting are illustrations throughout the manuscript that sometimes defy explanation—such as plants that no one has been able to identify. Some experts have suggested that the manuscript is a hoax, created by someone several centuries ago as a lark or ruse, for some unknown purpose. Others suggest the manuscript appears to be real in a sense as it does appear to follow some sort of grammar. In their paper, Arthur Tucker and Rexford Talbert suggest the key to solving the mystery might lie in the illustrations, rather than the text. One section of the manuscript appears to be devoted to botany—words flow across pages decorated with illustrations of mysterious plants. Tucker and Talbert noticed that at least one of the plants in the manuscript reminded them of a plant they’d seen illustrated in an old Mexican botany book. Their interest piqued, they gathered as many such texts as they could find and set to work looking to see if they could match plants in the botany books with those in the Voynich Manuscript. In so doing, they say they have found 37 matches out of the 303 depicted. They also note some matches between six animals and at least one mineral.The two botanists aren’t suggesting their findings prove anything, instead they suggest that perhaps more work ought to be done investigating the possibility that the manuscript was written in old Mexico in an ancient Aztec language such as Nahuatl, which is still actually spoken in some remote parts of Mexico. © 2014 Phys.org Citation: Botanists suggest Voynich illustrations similar to plants in Mexico (2014, February 5) retrieved 18 August 2019 from https://phys.org/news/2014-02-botanists-voynich-similar-mexico.html This document is subject to copyright.

Improving the accuracy of longread genome sequencing

first_img More information: Accurate circular consensus long-read sequencing improves variant detection and assembly of a human genome, Nature Biotechnology (2019). DOI: 10.1038/s41587-019-0217-9 Targeting DNA sequencing for plant biodiversity research Journal information: Nature Biotechnology The researchers began their work by noting that the current status quo in DNA sequencing technology allows for sequencing short sequences (short reads) accurately, or long sequences (long reads) less accurately. In this new effort, they sought to improve the accuracy of long-read sequencing. More specifically, they sought to improve the accuracy of a circular consensus sequencing (CCS) technique using single-molecule, real-time (SMRT) sequencing as performed by Pacific Bioscience (PacBio). Most of the team working on the project were from PacBio—other members were from Google, Stanford University, the Max Planck Institute, Saarland University, DNAnexius, NIST, the National Human Genome Research Institute, the Chinese Academy of Agricultural Sciences, the Dana-Farber Cancer Institute and Johns Hopkins University.The CCS technique (which is not considered a long-read technique) currently in use by PacBio involves the use of hairpin adapters, which are ligated onto the ends of DNA molecules to create a template. A polymerase starts at the adapter and moves across the DNA piece, adding bases as it goes, creating the read. The technique also involves moving the polymerase across the DNA bit multiple times. The researchers note that the CCS technique has typically been used with base lengths of 1000 to 2000 bases. By improving the technique, the team was able to read up to 10,000 bases accurately.The researchers report that their improvements were based mostly on improving the quality of DNA used at the start of sequencing. The quality of DNA was improved by starting the reactions before loading the DNA and then waiting for up to an hour—if they found the polymerase was still moving, it had to be of higher quality. They also made sure that the DNA molecules were all of uniform size—they did this by using a SageELF instrument.The team reports that the improved technique generated long reads (averaging 13.5 kilobases) with a 99.9 percent accuracy rate.

Rural youth Govt moves to encourage entrepreneurship

first_imgAfter successful launch of ‘Make in India’ campaign to a give a fillip to dying domestic manufacturing industry, the NDA government under the leadership of Prime Minister Narendra Modi is all set to launch Startup Village Entrepreneurship Programme by March this year. The scheme, which is a flagship programme promoted by PM Modi, aims to hone up entrepreneurship skills among rural youths by providing financial assistance as well as training assistance from the Centre. Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJITalking to Millennium Post, Rural Development Secretary LC Goyal informed that the structure of PM’s pet project has almost been finalised after consulting different stakeholders. “The final blue print of the scheme would be sent to the PM for his approval by the end of this month. After getting sanctioned from PM Modi, the project would be rolled out across the country within two months.”Giving details about the proposed scheme, Goyal said, “The scheme would help in providing employment to at least 2 lakh rural youth, which will lessen their dependency on rural job scheme. The Rural Development Ministry has planned a corpus fund of Rs 400 crore for the better implementation of village entrepreneurship programme.” Also Read – Health remains key challenge in India’s development: KovindOn the question of how it will function, the Rural Development Secretary said, “Suitable villages would be identified at every panchayat level and after that youths with entrepreneurship potential would be selected. The selected youths would be trained to hone up skills.”The financial assistance would be provided for opening of kirana stores, flour mills, toy manufacturing units, etc. There are no details about how many numbers of villages would be selected for first phase of this flagship programme, which will first start for the five years, Goyal said, on the sidelines of a press meet organised to spell out the achievements of Rural ministry in the seven months.“Though, it will too early to speculate about the success of village entrepreneurship programme, but one thing is clear that it will add only confusion among rural youths. In the country where there are about 14 lakh villages, such populist schemes would hardly make any impact,” said Madhuresh, a land reform activist.last_img read more

Dastangoi – from Gandhi to Mahatma

first_imgThe classic Urdu oral storytelling art form of ‘Dastangoi’ intertwined with the defiant poetry of the early 20th century brought alive the journey of Gandhi from ‘Mohandas to Mahatma’ in the national Capital.39-year-old Fouzia Dastango, credited as the first female Dastagoi artiste, presented ‘Dastan-e-Gandhi’ on the life and teachings of Mahatma Gandhi through the dying art form of ‘Dastangoi’ here recently.”The aim of Dastaan-e-Gandhi is to revive the abiding interest in the inspiring story of Mahatma Gandhi using newer ways to involve various stakeholders, including intelligentsia, academia and voluntary organizations to spread Bapu’s Message,” she said. Also Read – Add new books to your shelf”The young generation which is shaping today’s India and who will create the country’s future should be told about his life and his mission, and this is what we are doing,” she explained.’Dastaan-e-Gandhi’ performed by Fouzia and Fazal Rashid touched upon India’s struggle for freedom and Gandhi’s tryst with Satyagraha and his fight against injustice and racism. The event was organised by India International Center in collaboration with Sarvodaya International Trust. Also Read – Over 2 hours screen time daily will make your kids impulsiveProfessor Danish Iqbal, who penned the script for the performance, said it was a “mounting challenge” to present the life of Mahatma in an hour format.”There are many facets to Mahatma’s life. It was very challenging to present his life in a ‘Dastangoi’ format. But we focussed on the underlying the message of his life rather than talking about his milestones,” he said. Iqbal, who teaches at Jamia Millia Islamia University here, said many efforts were being taken to revive the art form of ‘Dastangoi’ and that the youth are the torchbearers of such a revival. “‘Dastangoi’ is a simple, yet powerful art form. It is performed by a minimum of two artistes. It does not require the expensive paraphernalia of lights, set and costumes. The art form is now being revived, especially by the young who are creating groups, like in theatre, to take Dastangoi to the masses,” he said.Fouzia, who has been performing ‘Dastangoi’ since the past 8 years, said her cultural roots have found their way back into her work.”I owe my performances to the by-lanes of Old Delhi. It is here that I performed for the first time. Apart from that, the events around me also translate into my work,” she said.The artiste has presented ‘Dastangoi’ on a range of issues, including the languages of Delhi, women issues and those concerning children.Talking about the relevance of Gandhian philosophy in contemporary times, Indira Verma of Sarvodaya International Trust said, “You call it idealism or romanticism, but I have a hope or I must say I am sure, the day will come when Gandhiism will become a reality more than a philosophy which will make this world a better place.” Fouzia said her dream was to perform at the Jama Masjid, where people from all walks of life, can be her audience. She summed up in her classical way of “Chaley Chalo ke Voh Manzil abhi Nahin Aayi (move ahead as the destination is far away)”.last_img read more
