    Identifying face attributes is an ongoing problem of research which is used in bio-metrics, surveillance etc. In past, researchers have proposed methods which predict single facial attribute at a time. Real-time applications ...
  • Sinkhorn attacks 
    Chaudhuri, Dibyendu Roy; Subramanyam, A.V. (Advisor) (IIIT-Delhi, 2021-07-01)
    Adversarial attacks have been extensively investigated in the recent past. Quite interestingly, a majority of these attacks primarily work in the lp space. In this work, we propose a novel approach for generating adversarial ...
  • A sketch-based approach towards scalable and efficient attributed network embedding 
    Chakraborty, Tapadeep; Bera, Debajyoti (Advisor) (IIIT-Delhi, 2021-12)
    With the advent of big data, graphs have gained popularity as one of the most efficient data storage mechanisms. A graph can not only capture relationships between entities, but it can also store attributes associated with ...
  • Solving matrix factorization from lower dimensional projections : applications in collaborative filtering and magnetic resonance imaging 
    Rajani, Anuj; Majumdar, Angshul (Advisor) (2014-07-10)
    Low-rank matrix factorization finds applications in large number of problems in signal processing and machine learning. Stochastic gradient descent (SGD) is a standard technique for solving large scale matrix factorization ...
  • SOS : save our object space 
    Aggarwal, Aniya; Purandare, Rahul (Advisor) (2014-12-12)
    Each Android application (app) runs in its own virtual machine (VM), with every VM allocated a limited heap size for creating new objects. The heap size is scarce and device dependent. The more heap space an app uses, ...
  • Spatio-temporal-history model : a deep learning model to predict traffic speed using public transport data 
    Gola, Nikhil; Goyal, Vikram (Advisor) (IIIT-Delhi, 2020-06)
    Traffic speed prediction is one of the challenging task and has many applications. Existing solutions either use crowd-sourced data or sophisticated technologies to perform the task, and hence are costly and unreliable. ...
  • ST-optics: a spatial-temporal clustering algorithm with time recommendations for taxi services 
    Malhan, Avni; Gunturi, Venkata M. Viswanath (Advisor); Naik, Vinayak (Advisor) (2017-06)
    Taxis have become the most popular and preferred mode of transport because of the comfort and convenience they offer. In this work, we design a novel algorithm, called ST-OPTICS, which helps taxi fleet owners to manage ...

    Kumar, Abhishek; Naik, Vinayak (Advisor) (2015-12-02)
    The number of desk jobs have increased phenomenally with the evolution of computers, especially in the last few decades. A modern day worker who is indulged into desk job spends nearly one third of her daily time sitting ...
  • Static technique for bug localization using character N-Gram based information retrieval model 
    Sangeeta (2012-03-14)
    Bug or Fault localization is a process of identifying the speci c location(s) or region(s) of source code (at various granularity levels such as the directory path, le, method or state- ment) that is faulty and needs ...
  • Study of community aware network expanion 
    Sarika; Goyal, Vikram (Advisor); Chakraborty, Tanmoy (Advisor) (2018-06)
    Community detection has gained immense popularity in recent years. Real world networks consist of millions of nodes and edges. Groups of nodes exhibit interesting characteristics, whoseknowledge can be of great help in ...
