## May 25th 2015, Weighted Least Squares

With ordinary least squares fitting all measurements $m_i$ are treated equally. But for example in our GPS fitting scenario older points should contribute less than newer ones. So the measurements need to be weighted differently by introducing weights $w_i$ in the sum of residuals:

$R = \sum_i w_i(f(t_i)-m_i)^2$

Again, we find the minimum by setting the gradient to zero: $\nabla R=0$.

Calculating the partial derivatives of the gradient leads to the following three linear equations:

$\frac{dR}{dc_0} = \sum_i 2(w_i c_0 + w_i c_1 t_i + w_i c_2 t_i^2 - w_i m_i) w_i = 0$
$\frac{dR}{dc_1} = \sum_i 2(w_i c_0 + w_i c_1 t_i + w_i c_2 t_i^2 - w_i m_i) w_i t_i = 0$
$\frac{dR}{dc_2} = \sum_i 2(w_i c_0 + w_i c_1 t_i + w_i c_2 t_i^2 - w_i m_i) w_i t_i^2 = 0$

This corresponds to the following system of linear equations:

$\left( \begin{array}{c c c} \sum_i w_i^2 & \sum_i w_i^2 t_i & \sum_i w_i^2 t_i^2 \\ \sum_i w_i^2 t_i & \sum_i w_i^2 t_i^2 & \sum_i w_i^2 t_i^3 \\ \sum_i w_i^2 t_i^2 & \sum_i w_i^2 t_i^3 & \sum_i w_i^2 t_i^4 \end{array} \right) \left( \begin{array}{c} c_0 \\ c_1 \\ c_2 \end{array} \right) = \left( \begin{array}{c} \sum_i w_i^2 m_i \\ \sum_i w_i^2 m_i t_i \\ \sum_i w_i^2 m_i t_i^2 \end{array} \right)$

Solving for $(c_0, c_1, c_2)^T$ yields:

$\left( \begin{array}{c} c_0 \\ c_1 \\ c_2 \end{array} \right) = \left( \begin{array}{c c c} \sum_i w_i^2 & \sum_i w_i^2 t_i & \sum_i w_i^2 t_i^2 \\ \sum_i w_i^2 t_i & \sum_i w_i^2 t_i^2 & \sum_i w_i^2 t_i^3 \\ \sum_i w_i^2 t_i^2 & \sum_i w_i^2 t_i^3 & \sum_i w_i^2 t_i^4 \end{array} \right)^{-1} \left( \begin{array}{c} \sum_i w_i^2 m_i \\ \sum_i w_i^2 m_i t_i \\ \sum_i w_i^2 m_i t_i^2 \end{array} \right)$

If the system of linear equations is overdetermind (e.g. if $n<3$), we use a linear polynomial $f(t)=c_0+c_1t$ instead of a quadratic polynomial function as a fallback solution:

$\left( \begin{array}{c c} \sum_i w_i^2 & \sum_i w_i^2 t_i \\ \sum_i w_i^2 t_i & \sum_i w_i^2 t_i^2 \end{array} \right) \left( \begin{array}{c} c_0 \\ c_1 \end{array} \right) = \left( \begin{array}{c} \sum_i w_i^2 m_i \\ \sum_i w_i^2 m_i t_i \end{array} \right)$

So that

$\left( \begin{array}{c} c_0 \\ c_1 \end{array} \right) = \left( \begin{array}{c c} \sum_i w_i^2 & \sum_i w_i^2 t_i \\ \sum_i w_i^2 t_i & \sum_i w_i^2 t_i^2 \end{array} \right)^{-1} \left( \begin{array}{c} \sum_i w_i^2 m_i \\ \sum_i w_i^2 m_i t_i \end{array} \right)$

If this system is overdetermined, again, the solution corresponds to a constant polynomial function $f(t)=c_0$ with

$c_0 = \frac{\sum_i w_i^2 m_i}{\sum_i w_i^2 }$

This is a bit speculative; some of it might be wrong, silly, or both.

Suppose $G$ is a groupoid all of whose connected components are finite, and $k$ is a field of characteristic zero. Consider the category $SuperDG_k(G)$ consisting of superspace representations $(V_0, V_1)$ consisting of functors from $G$ into finite-dimensional superspaces, equipped with $G$-equivariant differentials $\partial_0: V_0 \to V_1, \partial_1: V_1 \to V_0$. I propose to define the category of virtual representations of $G$ to be the localization of $SuperDG_k(G)$ with respect to quasi-isomorphisms (morphisms that induce isomorphisms in homology).

This might very well dissolve into something much more trivial than it sounds, but the rough idea anyway is that an object represented by $(V_0, V_1, \partial_\ast)$ plays the role of $V_0 - V_1$. Ordinary representations embed fully and faithfully as $V \mapsto (V, 0)$ with zero differentials. There is a supersymmetry functor given by degree shift modulo $2$ (if I’m using the word correctly, something that exchanges bosons and fermions), playing the role of additive inversion.

The category has a symmetric monoidal structure in the expected way. I’m hoping it decategorifies to the representation ring.

Some old notes of mine on the Lie operad (housed at Baez’s website) seemed to use this idea implicitly, but I had never bothered to formalize it. Perhaps something like this appears in the literature?

Ah, great; thanks! So maybe it’s not such a silly idea. :-)

For what it’s worth, the methodological lesson I took away way back when was: when doing these categorified calculations that pertain to “virtual species”, remain for as long as you can up in $SuperDG_k(\mathbb{P})$ before descending down to the homotopy category, taking advantage of any/all benefits such as model category structure.

Could one look at the 2-category instead, incorporating homotopies? It’s not a priori (to me) obvious that quasi-isomorphisms and equivalences in this 2-category coincide.

Have you seen Construction 6.2.1 in Lurie’s “Rotation invariance in algebraic K theory” paper? (The construction is much older- I think due to Quillen?- but that was just the quickest reference I could find). If you do the same thing with representations then you categorify the representation ring. I’m not sure how to relate it to your super-construction…

Dylan, it looks related, but I don’t think it’s doing what I quite want. For example, it seems to be the core groupoid of $Vect$ that embeds fully and faithfully into the category, whereas (for this toy case of the terminal groupoid $G$) I would want all of $Vect$ to embed.

## On the Complexity of Approximating Wasserstein Barycenters

P. 3530-3540.

We study the complexity of approximating the Wasserstein barycenter of m discrete measures, or histograms of size n, by contrasting two alternative approaches that use entropic regularization. The first approach is based on the Iterative Bregman Projections (IBP) algorithm for which our novel analysis gives a complexity bound proportional to $m n^2 / \epsilon^2$ to approximate the original non-regularized barycenter. On the other hand, using an approach based on accelerated gradient descent, we obtain a complexity proportional to $m n^2 / \epsilon$. As a byproduct, we show that the regularization parameter in both approaches has to be proportional to $\epsilon$, which causes instability of both algorithms when the desired accuracy is high. To overcome this issue, we propose a novel proximal-IBP algorithm, which can be seen as a proximal gradient method, which uses IBP on each iteration to make a proximal step. We also consider the question of scalability of these algorithms using approaches from distributed optimization and show that the first algorithm can be implemented in a centralized distributed setting (master/slave), while the second one is amenable to a more general decentralized distributed setting with an arbitrary network topology.

# Understanding superposition for a layer model

1. Apr 6, 2015

### VictorVictor5

Greetings all,

This question can cover many sub-forums here, but I'll put it in General Math since I believe it deals with superposition.

Now, I am studying a layered-earth model for programming purposes, and what I mean by that is, for example, we say air is one layer, grass is another, and the dirt underneath is the final layer. So in essence this would be a three layer system. What I'm trying to understand is an equation that defines N-layers to something called apparent conductivity. But I'm more concerned about the right hand side of the equation.

Now, while I present pseudo-code here to demonstrate, if anyone needs me to go in to more detail or write in Latex, let me know.

So, for the three layered system, the equation for apparent conductivity looks like:

sigma_a = sigma1*(1-R(z1))+sigma2*(R(z1)-R(z2))+sigma3*R(z2)

where sigma 1 is the conductivity of the first layer, sigma 2 is the conductivity of the second layer, etc., and R(z1) and R(z2) are the relative contributions to the apparent conductivity from all material below a certain layer.

Now, say we have a 4 layer system. Now the equation expands to:

sigma_a = sigma1*(1-R(z1))+sigma2*(R(z1)-R(z2))+sigma3*R(z2)-R(z3))+sigma4*R(z3)

Now the first part (sigma1*(1-R(z1))) will always stay the same. The last part (sigma4*R(z3)) stays the same and can be written as sigma_N*R(z(N-1)), where N is the total amount of layers. But the middle information is always going to increase depending on the total number of layers.

This is where I think it has to do with superposition in some way but I am having a difficult time seeing it. Any assistance would be appreciated.

Thanks!

 Title: Mechanisms of Neural Synchrony: Developing a Novel Behavioral Paradigm Featuring Cross-Modal Attention Authors: Duncan, Kristen M. Advisors: Buschman, Timothy J. Department: Molecular Biology Class Year: 2016 Abstract: Cognitive control encompasses a range of cognitive processes required for selecting behaviors critical to attaining a particular goal. Attention is a subset of cognitive control, and acts to select for what the brain’s limited processing capacity is used. It has been suggested that the synchronization of oscillations within and between areas is the mechanism underlying attentional processes; however, a causal link between the two has yet to be found. As synchronous patterns are disrupted in many neuropsychiatric and neurodevelopmental disorders, including schizophrenia, autism spectrum disorders, Parkinson’s, and Alzheimer’s diseases, we are motivated to understand the mechanisms underlying synchronous activity. The ultimate goal of this research is to examine the possibility of a causal link between attention and gamma-band oscillations; therefore, it is first necessary to develop a paradigm that tests a mouse’s ability to attend. In this case, we are using cross-modal attention, requiring the animal to attend into and out of the somatosensory and auditory modalities. To do this, we trained two cohorts of mice on two behavioral tasks: the first, with the goal of teaching subjects to attend into the auditory modality using a sound stimulus, and the second, with the goal of attending to into the vibrissae modality using a whisker stimulus. As only one subject from the first cohort learned to attend to the sound stimulus, and four subjects learned to attend to the whisker stimulus, we have identified several ways to improve upon future paradigms.
