Robot cockroach becomes part of the club

Robot Cockroach Tests Insect Decision-Making Behavior Elizabeth Pennisi

Robot cockroaches coated with pheromones are so well accepted by the
household pests that the robots become part of the insects’ collective
decision-making process, researchers report on page 1155 of this week’s
issue of Science. (For more on robotics, see this week’s special section.)

    Evolutionary and Developmental Precursors to a Concept of Number

    Adult humans quantify, label, and categorize almost every aspect of the world with numbers. The ability to use numbers is one of the most complex cognitive abilities that humans possess and is often held up as a defining feature of the human mind. In my talk I will present a body of data that demonstrates that there are strong developmental and evolutionary precursors to adult mathematical cognition that can be seen by studying human infants and nonhuman primates. I will demonstrate the similarities in the psychophysics of numerical discrimination in adults, monkeys, and human infants, explore the relationship between the representation of number and continuous variables, and experimentally illustrate the amodal and abstract nature of nonverbal number representation. Further I will describe research using ERPs with infants, fMRI with children, and single-unit recordings with monkeys that suggests that the neural bases of numerical cognition are similar throughout development and likely to be evolutionarily ancient.

    Subspectral Algorithms for Sparse Learning, Optimization & Inference

    I will present a general class of “subspectral” algorithms (sparse
    eigenvector techniques) for solving NP-hard combinatorial optimization
    problems in three applied domains: (Un)Supervised Learning (e.g. PCA &
    LDA), Quadratic/Entropic Optimization (e.g. Least-Squares & MaxEnt)
    and 3) Bayesian Inference (e.g. Automatic Relevance Determination).
    Efficient algorithms for both optimal and approximate greedy solutions
    are derived using analytic eigenvalue bounds. Sample applications
    presented include “sparse PCA” for variable selection (in statistics),
    “sparse LDA” for classification (gene discovery), sparse kernel
    regression (robotics & control), sparse quadratic programming
    (portfolio optimization), graph model selection (sensor networks) and
    sparse Bayesian inference for computer vision (face recognition &

    *Biography:* Baback Moghaddam joined the Jet Propulsion Laboratory in 2007
    as a Principal Member, with the Machine Learning and Instrument Autonomy Group.
    Prior to JPL he was a Senior Research Scientist at the Mitsubishi Electric Research
    Laboratory (MERL) since 1997. He received his Ph.D. in Electrical Engineering and
    Computer Science from the Massachusetts Institute of Technology in 1997, where
    he was a member of the Vision & Modeling Group of the MIT Media Laboratory
    since 1992. As part of his doctoral work at MIT he developed an automatic face
    recognition system which won the 1996 DARPA “FERET” Face Recognition
    competition. He has authored numerous articles on 2D face recognition and 3D
    facial modeling in leading journals and conferences, including the core chapter in
    Springer-Verlag’s Biometric Series, The Handbook of Face Recognition.
