+  <abstract><p>
+  Deep networks can be learned efficiently from unlabeled data. The layers of
+  representation are learned one at a time using a simple learning module,
+  called a "Restricted Boltzmann Machine" that has only one layer of latent
+  variables. The values of the latent variables of one module form the data for
+  training the next module. Although deep networks have been quite successful
+  for tasks such as object recognition, information retrieval, and modeling
+  motion capture data, the simple learning modules do not have multiplicative
+  interactions which are very useful for some types of data.
+  </p><p>
+  The talk will show how a third-order energy function can be factorized to
+  yield a simple learning module that retains advantageous properties of a
+  Restricted Boltzmann Machine such as very simple exact inference and a very
+  simple learning rule based on pair-wise statistics. The new module contains
+  multiplicative interactions that are useful for a variety of unsupervised
+  learning tasks. Researchers at the University of Toronto have been using this
+  type of module to extract oriented energy from image patches and dense flow
+  fields from image sequences. The new module can also be used to allow motions
+  of a particular style to be achieved by blending autoregressive models of
+  motion capture data.

+  The interactive proof system model of computation is a cornerstone of complexity
+  theory, and its quantum computational variant has been studied in quantum
+  complexity theory for the past decade. In this talk I will discuss an exact
+  characterization of the power of quantum interactive proof systems that I
+  recently proved in collaboration with Rahul Jain, Zhengfeng Ji, and Sarvagya
+  Upadhyay. The characterization states that the collection of computational
+  problems having quantum interactive proof systems consists precisely of those
+  problems solvable with an ordinary classical computer using a polynomial amount
+  of memory (or QIP = PSPACE in complexity-theoretic terminology). This
+  characterization implies the striking fact that quantum computing does not
+  provide any increase in computational power over classical computing in the
+  context of interactive proof systems.
+
+  </p><p>I will not assume that the audience for this talk has any familiarity with
+  either quantum computing or complexity theory; and to be true to the spirit of
+  the interactive proof system model, I hope to make this talk as interactive as
+  possible -- I will be happy to explain anything related to the talk that I can
+  that people are interested in learning about.

+    <abstract><p>
+    Cairo is an open source, cross platform, vector graphics library with the
+    ability to output to many kinds of surfaces, including PDF, SVG and PNG
+    surfaces, as well as X-Window, Win32 and Quartz 2D backends.
+    </p><p>
+    Unlike the raster graphics used with programmes and libraries such as The
+    Gimp and ImageMagick, vector graphics are not defined by grids of pixels,
+    but rather by a collection of drawing operations. These operations detail
+    how to draw lines, fill shapes, and even set text to create the desired
+    image. This has the advantages of being infinitely scalable, smaller in file
+    size, and simpler to express within a computer programme.
+    </p><p>
+    This talk will be an introduction to the concepts and metaphors used by
+    vector graphics libraries in general and Cairo in particular.
