  • Classifier Chains for Multi-label Classification (HIIT Events)

    28.03.2014 10:15–11:15
    HIIT seminar
    Exactum B119
    Title: Classifier Chains for Multi-label Classification
     
    Abstract: Work on multi-label classification in the academic literature has expanded prolifically in recent years. In the multi-label scenario, each data instance may be associated with multiple class labels simultaneously (as opposed to a single class label, as in the traditional classification task). This context arises naturally...

  • Addition chains meet postage stamps: Number theory helps multiplication (HIIT Events)

    21.03.2014 10:15–11:15
    HIIT seminar

    Title:
     
    Addition chains meet postage stamps: Number theory helps multiplication
     
     
    Abstract:
     
    Addition chains are integer sequences such as (1,2,4,8,10), where each element is a pairwise sum of earlier elements, for example 8 = 4+4.  They are commonly used to optimize repeated multiplication: if x is...

    Title:
    Addition chains meet postage stamps: Number theory helps multiplication

    Abstract:
    Addition chains are integer sequences such as (1,2,4,8,10), where each element is a pairwise sum of earlier elements, for example 8 = 4+4.  They are commonly used to optimize repeated multiplication: if x is given, and x^10 is required, one computes successively x^2, x^4, x^8 and then x^10 = x^2 * x^8. The...

  • 20/03/14: ICS Forum: New Insights on Parameter Estimation of Boltzmann Machines and Deep Neural Architectures (Nando de Freitas, Oxford University) (Aalto CS Events)

    New Insights on Parameter Estimation of Boltzmann Machines and Deep Neural Architectures

    Prof. Nando de Freitas, Oxford University, UK

    Abstract:

    The talk has two new insights. First, I will show that it is possible to train most deep learning approaches -regardless of the choice of regularization, architecture, algorithms and datasets ? by learning only a small number of the parameters and predicting the rest with non-parametric methods. Often, this approach makes it possible to...

  • 17/03/14: HIIT Otaniemi Seminar: The Crowd-Median Algorithm (Antti Ukkonen, HIIT) (Aalto CS Events)

    The Crowd-Median Algorithm

    Dr. Antti Ukkonen, HIIT

    Abstract:

    The power of human computation is founded on the capabilities of humans to process qualitative information in a manner that is hard to reproduce with a computer. However, all machine learning algorithms rely on mathematical operations, such as sums, averages, least squares etc. that are less suitable for human computation.

    This paper is an effort to combine these two aspects of data processing. We consider the...
