Simultaneous Twin Kernel Learning Using Polynomial Transformations for Structured Prediction
No full textMany learning problems in computer vision can be posed as structured prediction problems, where the input and output instances are structured objects such as trees, graphs or strings rather than, single labels {+1, −1} or scalars. Kernel methods such as Structured Support Vector Machines , Twin Gaussian Processes (TGP), Structured Gaussian Processes, and vector-valued Reproducing Kernel Hilbert Spaces (RKHS), offer powerful ways to perform learning and inference over these domains. Positive definite kernel functions allow us to quantitatively capture similarity between a pair of instances over these arbitrary domains. A poor choice of the kernel function, which decides the RKHS feature space, often results in poor performance. Automatic kernel selection methods have been developed, but have focused only on kernels on the input domain (i.e.’one-way’). In this work, we propose a novel and efficient algorithm for learning kernel functions simultaneously, on both input and output domains. We introduce the idea of learning polynomial kernel transformations, and call this method Simultaneous Twin Kernel Learning (STKL). STKL can learn arbitrary, but continuous kernel functions, including ’one-way’ kernel learning as a special case. We formulate this problem for learning covariances kernels of Twin Gaussian Processes. Our experimental evaluation using learned kernels on synthetic and several real-world datasets demonstrate consistent improvement in performance of TGP’s.Peer reviewe
The study of open source CMSs
No full textIn this thesis, we evaluate different Open Source Content Management Systems (CMSs) and determine their appropriateness for scientific research laboratories' website content management. We describe different CMSs and evaluate them based on the following criteria: ease of installation, usability, maintenance and updates, scalability, community strength and support, user roles and workflow, security, and Web 2.0 features. We then choose one of these systems, Drupal, and demonstrate its effectiveness for two different scientific websites, Bio-1 and Vizlab. Drupal allows integrating new features using community contributed modules and easy future up-gradation. Successful implementation of both projects using Drupal highlights the importance of Open Source CMSs.M.S.Includes abstractIncludes bibliographical referencesby Chetan Gopilal Jai

ERP Systems are generally thought of as being huge, bulky software and\ud
hardware systems that hold the functioning of large enterprises together. This notion is\ud
mostly true, but the picture is changing rapidly. Over the past two decades, a major proportion\ud
of computer software development has been in the ERP domain. However, such\ud
software systems are affordable only by sufficiently large businesses. Small scale industries\ud
and startups have similar business needs, though at a smaller scale. For instance,\ud
small scale industries too want a good business analysis tool to make smart business\ud
decisions and compete in the market. They also face issues with managing the business\ud
and improving the core processes of the company. ERP systems, though not affordable,\ud
would be very beneficial to smaller businesses.CSU, Chic
System integration and image pre-processing for an automated, real-time identification and monitoring system for coral reef fish
No full textIn this work we build an underwater vision system capable of monitoring the activities of fish found near coral reefs. We propose a unique hardware platform capable of monitoring a volume of water in a very efficient and cost effective way. We also develop algorithms required to take advantage of such a system. There are three main contributions of this work, which are; (1) using two right-angled camera’s to capture underwater image sequences, (2) developing algorithms to track and pre-process images for recognition (3) and demonstrating that we can recognize fish families or in some cases exact fish species using fish shape(with size, color and pattern features to be added later). We conclude from this work that using just two cameras in a right-angled setup is a cheap and effective way of monitoring fish activities in general. It is cost effective when compared to using multiple cameras and also less computationally intensive. We developed and modified our approach based on observations we made while testing this setup and accommodated these modifications in our software. We installed this system at the artificial coral reef in the New York Aquarium and periodically collected image sequences for processing. We demonstrate our results on the collected sequences and show pre-processing results on them. We also demonstrate, using shape feature from a fish sequence we collected at the aquarium (using cross-validation); that we can recognize fish families or in some cases exact species using those features.M.S.Includes bibliographical referencesby Chetan Tond
Improving Bicycle Safety through Automated Real-Time Vehicle Detection
No full textThe manner in which people use bicycles has changed very little since their invention in 1817. In that time, though, roadways have become congested with a dramatically less environmentally friendly mode of transportation: automobiles. These vehicles and the motorists who drive them represent, at times, a serious threat to the safety of both road cycling enthusiasts and bicycle commuters alike. Since bikers typically ride with the ow of trac, the most dangerous situation for them is when they are being passed by a motorist from behind. As a result, a biker must spend a substantial amount of her cognitive and physical ability to periodically scan for rear-approaching vehicles, reducing her capacity to handle the bicycle safely and maintain continual awareness for both the forward and rearward situations.To improve road cycling safety, we present a system that augments a standard bicycle with audio and video sensing, and computational capabilities. This Cyber-Physical bicycle system continuously senses the environment behind a biker, processes the sensed data utilizing audio processing and computer vision techniques, automatically detects the occurrences of rear-approaching vehicles, and alerts the biker in real time prior to the encounter. In this paper we present (i) the design of our prototype Cyber-Physical bicycle system and (ii) the results of our evaluation using video and audio traces collected from bikers. These results demonstrate both the feasibility of the system, exhibiting a high degree of detection accuracy while operating under the real-time and energy constraints of the problem scenario.Technical report DCS-TR-66
Chetan Bhagat: Recent Readings: Mental conflicts of Indian women in One Indian Girl
No full textThis chapter is written to have a look at Chetan Bhagat’s novel One Indian Girl from cerebral angle to acknowledge a deviation in Indian Women’s demeanor and behaviour. Indian women’s mind is full of conflicts and confusion. They have to deal with social stereotypes. Our society believes that girls can make a successful career either or a successful home. Can’t do both together. What an astonishment! We give wings to our daughters but then she is told that she has to build a nest. So she has to forget to fly. Chetan Bhagat’s novel One Indian Girl offers a female’s anima – her goals and inclination in her thoughts and geared up to flare up and ensue at even the slightest pierce. Radhika Mehta cogitates a maiden who is a sturdy backer of feminist ideology however she has to confront the pre-determined norms of Indian society that have been set below patriarchal society because of which she has to go through numerous sorts of torments and distress. This narrative is generally about Radhika, the proponent, unveiling the exceptional elements of a modern-day Indian woman. Radhika’s social reputation influences society to a great extent that she turns into a vulnerable target of many known and unknown conditions which vexed her unfulfilled objectives of not getting bodily love and appreciation. Radhika’s unfulfilled dreams take her foundation within side the discrimination meted to her in her formative years and youth. It is a first-character narrative through the protagonist whose internal voice (named ‘Mini-me’) constantly expresses her internal feelings and the mental conflicts occurring in her thoughts

Dilemma of Modern Indian Bride: A Critical Analysis of Chetan Bhagat's One Indian Girl
No full textIn an advent of post-modern era; India is evolving as a new country in their lifestyle, career orientation, relationships, and many others. Like every other phenomena marriage system is also changing although the importance of marriage is still deeply down in Indians veins. In this period when technology is growing so fast and people are connected by means of cyber even though they are thousand miles away. The relationships are forming and breaking in this place and period simultaneously. One such relationship we also witness in this novel. In this present paper we will talk about the dilemma of a young Indian girl who is about to get married and what her mini-me tries to allude her to her inner self. In this paper we will analyze the hustle and bustle of marriage in Indian families. The story is all about Radhika Mehta, an investment banker at Goldman Sachs in New York. The whole story revolves around the protagonist \u27s life and marriage. Chetan Bhagat\u27s keen projection of women\u27s inner self is commendable in every sense; he displayed turmoil of Indian Bride in a comprehensive way that every Indian girl feels connected to Radhika\u27s abeyance. This research paper\u27s ingenious effort is to bring in light all the aspects which makes Radhika to cancel her destination wedding
Collective action for forest conservation: Does heterogeneity matter?
No full textCommunity management of forests by Van Panchayats (forest councils) to meet local needs has a long history in the Indian Central Himalayas. This essay examines the effects of village-level heterogeneity in caste and land ownership, and of female membership in the Panchayats on collective action for forest conservation. There is no evidence that caste heterogeneity or female membership of the Panchayat have any effect. There is some evidence that greater equality in land ownership may enhance collective action and forest conservation in pine forests but not broadleaved forests. This is puzzling since villagers' interest in conservation is greater in broadleaved than in pine forests.
