Upcoming EventsFatma Kilinc-Karzan — Online First-Order Framework for Robust Convex Optimization, Nov 20
http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=113253&date=2017-11-20
Robust optimization (RO) has emerged as one of the leading paradigms to efficiently model parameter uncertainty. The recent connections between RO and problems in statistics and machine learning domains demand for solving RO problems in ever more larger scale. However, the traditional approaches for solving RO formulations based on building and solving robust counterparts or the iterative approaches utilizing nominal feasibility oracles can be prohibitively expensive and thus significantly hinder the scalability of RO paradigm. <br />
<br />
We present a general and flexible iterative framework to solve robust convex optimization problems that is built on a fully online first-order paradigm. In contrast to the existing literature, a key distinguishing feature of our approach is that it requires access to only cheap first-order oracles for the original problem that are remarkably cheaper than pessimization or nominal feasibility oracles, while maintaining the same convergence rates. This, in particular, makes our approach much more scalable and hence preferable in large-scale applications. In the case of strongly convex functions, we also establish a new improved iteration complexity addressing an open question in the literature. Motivated by a robust portfolio optimization problem, we demonstrate our approach on robust quadratic programs with ellipsoidal uncertainty.<br />
<br />
If time permits, we will discuss connections and applicability of our online framework in the context of joint estimation and optimization problems.<br />

http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=112939&date=2017-11-27
We develop a framework to analyze the consequences of alternative designs for interbank networks, in which a failure of one bank may lead to others. Earlier work had suggested that, provided shocks were not too large (or too correlated), denser networks were preferred to more sparsely connected networks because they were better able to absorb shocks. With large shocks, especially when systems are non-conservative, the likelihood of costly bankruptcy cascades increases with dense networks. Governments, worried about the cost of bailouts, have proposed bail-ins, where creditors of defaulting banks voluntarily contribute to rescue their debtors.<br />
However, credibility and enforceability were again at issue. How can the government enforce private sector involvement when the private sector knows that in the absence of its cooperation, the government would nonetheless proceed with a bailout? While a few bail-ins have been observed in practice, it has not been understood until recently under which conditions they exist. <br />
<br />
We answer in the affirmative the key question of whether credible bail-in strategies exist, showing that this strongly depends on the network structure. We model the coordination of a rescue consortium between a social planner and the banks as a sequential game. We show that the equilibrium welfare losses are generically unique, and characterize the subgame perfect equilibrium of the game yielding the optimal intervention plan.<br />
<br />
Our findings reverse the presumptions in earlier works and promote sparsely connected networks over densely connected ones because (i) the no-intervention threat exhibits a phase transition and becomes more credible for large shocks and (ii) banks' contributions to the coordinated bail-in plan are larger. <br />

http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=113259&date=2017-11-27
Abstract: Practical exact methods for global optimization of mixed-integer nonlinear optimization formulations rely on convex relaxation. Then, one way or another (via refinement and/or disjunction), global optimality is sought. Success of this paradigm depends on balancing tightness and lightness of relaxations. We will investigate this from a mathematical viewpoint, comparing polyhedral relaxations via their volumes. Specifically , I will present some results concerning: fixed charge problems, vertex packing in graphs, boolean quadratic formulations, and convexification of monomials in the context of spatial branch-and-bound" for factorable formulations. Our results can be employed by users (at the modeling level) and by algorithm designers/implementers alike. <br />

http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=114634&date=2018-01-26
Abstract: Process flexibility has been widely applied in many industries as a competitive strategy to improve responsiveness to demand uncertainty. The first part of the talk addresses the problem of managing process flexibility in a fairly general manufacturing system. In our model, each plant might have a different cost for adding flexibility or extra capacity. We model this problem as an adaptive optimization problem and discuss different approaches to solve it efficiently. <br />
In the second part of the talk, we discuss a distribution-free model to evaluate the performance of process ﬂexibility structures when only the mean and partial expectation of the demand are known. We characterize the worst-case demand distribution under general concave objective functions and apply it to derive tight lower bounds for the performance of chaining structures under the balanced systems. In the third part of the talk, we examine the worst-case performance of flexibility designs under supply and demand uncertainties, where supply uncertainty can be in the form of either plant or arc disruptions.<br />

http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=114846&date=2018-01-29
Abstract: We describe a novel family of models of multi-layer feedforward neural networks, where the activation functions are encoded via penalties in the training problem. The new framework allows for algorithms such as block-coordinate descent methods to be applied, in which each step is composed of simple (no hidden layer) supervised learning problems that are parallelizable across layers, or data points, or both. Although the training problem has many more variables than that of a standard network, preliminary experiments seem to indicate that the proposed models provide excellent initial guesses for standard networks, and could become competitive with state-of-the-art neural networks, both in terms of performance and speed. In addition, the lifted models provide avenues for interesting extensions such as network topology optimization, input matrix completion, and robustness against noisy inputs.http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=114846&date=2018-01-29Wenpin Tang - Optimal Surviving Strategy For The Up The River Problem, Feb 5
http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=115023&date=2018-02-05
Abstract:<br />
<br />
Nowadays there are more and more people living on the planet, but the available resources are very limited. So an interesting question is how to allocate the limited resources to maximize our welfare.<br />
<br />
In this talk, I will present the "Up the River problem" which is a dynamic allocation model in a random environment with limited resources. The model was introduced by David Aldous in 2000, along with a couple of open problems. A unit drift is distributed among a finite collection of Brownian particles on R+, which are annihilated once they reach the origin. Starting K particles at x = 1, we prove Aldous' conjecture that the push-the-laggard strategy of distributing the drift asymptotically (as K → ∞) maximizes the total number of surviving particles, with approximately √ 4 π K1/2 surviving particles. The solution to the problem relies on stochastic calculus and partial differential equations: the hydrodynamic limit of the particle density satisfies a two-phase partial differential equations, one with a fix boundary and the other with a free boundary.<br />
<br />
At the end of the talk, I will discuss recent progress in continuous-time information search model, initiated by Ke and Villas-Boas. The techniques in solving the "Up the River problem" can also be applied to these search models. The talk is based on joint work with Li-Cheng Tsai (Up the River problem), Tony Ke and J.Miguel Villas-Boas <br />

http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=115024&date=2018-02-12
The problem of optimizing over the cone of nonnegative polynomials is a fundamental problem in computational mathematics, with applications to polynomial optimization, control, machine learning, game theory, and combinatorics, among others. A number of breakthrough papers in the early 2000s showed that this problem, long thought to be intractable, could be solved by using sum of squares programming. This technique however has proved to be expensive for large-scale problems, as it involves solving large semidefinite programs (SDPs).<br />
<br />
In the first part of this talk, we present two methods for approximately solving large-scale sum of squares programs that dispense altogether with semidefinite programming and only involve solving a sequence of linear or second order cone programs generated in an adaptive fashion. In the second part of the talk, we focus on the problem of finding tight lower bounds on polynomial optimization problems (POPs), a fundamental task in this area that is most commonly handled through the use of SDP-based sum of squares hierarchies (e.g., due to Lasserre and Parrilo). In contrast to previous approaches, we provide the first theoretical framework for efficiently constructing converging hierarchies of lower bounds on POPs whose computation does not require any optimization, but simply the ability to multiply certain fixed polynomials together and check nonnegativity of the coefficients of the product.<br />

http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=115453&date=2018-02-14
Abstract: Analysis of large-scale communication networks (e.g. ad hoc wireless networks, cloud computing systems, server networks etc.) is of great practical interest. The massive size of such networks frequently makes direct analysis intractable. Asymptotic approximations using hydrodynamic and diffusion scaling limits provide useful methods for approaching such problems. In this talk, we study two examples of such an analysis. In the first, the technique is applied to a model for load balancing in a large, cloud-based, storage system. In the second, we present an asymptotic method of solving control problems in such networks.<br />
<br />
Bio: Eric Friedlander's research is focused on the modeling and analysis of large scale systems arising from communication networks and biological systems. As more and more business is conducted online, massive cloud-based storage systems and market places have created the need for models and methodology applicable on a scale that is currently impracticable. In his research, he studies these types of systems and develop tractable methods of approaching the problems which arise. In addition, he am interested in the study of data assimilation methods for complex high-dimensional systems. Data assimilation is the science of incorporating data into complex deterministic dynamical models (normally described through a system of ODE/PDE). Such a process is often complicated by the massive size of such systems and various methods have been developed to cope with this challenge.http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=115453&date=2018-02-14Zeyu Zheng - Top-Down Statistical Modeling, Feb 16
http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=115492&date=2018-02-16
Abstract: In this talk, we will argue that data-driven service systems engineering should take a statistical perspective that is guided by the decisions and performance measures that are critical from a managerial perspective. We further take the view that the statistical models will often be used as inputs to simulations that will be used to drive either capacity decisions or real-time decisions (such as dynamic staffing levels). We start by discussing Poisson arrival modeling in the context of systems in which time-of-day effects play a significant role. We will discuss several new statistical tools that we have developed that significantly improve the quality of the performance predictions made by the simulation models. In the second part of our talk, we show that in dealing with high-intensity arrival streams (such as in the call center and the ride-sharing contexts), the key statistical features of the traffic that must be captured for good performance prediction lie at much longer time scales than the inter-arrival times that are the usual focus of conventional statistical analysis for such problems. This observation is consistent with the extensive limit theory available for many-server systems. Our “top-down” approach focuses on data collected at these longer time scales, and on building statistical models that capture the key data features at this scale. In particular, we will discuss the use of Poisson auto-regressive processes as a basic tool in such “top-down” modeling, and on the statistical framework we are creating to build effective simulation-based decision tools based on real-world data.<br />

http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=115025&date=2018-02-21
Abstract<br />
With the emergence of big-data technologies, cloud computing systems are growing rapidly in size and becoming more and more complex, making it costly to conduct experiments and simulations. Therefore, modeling computing systems and characterizing their performance analytically are more critical than ever in identifying bottlenecks, informing system design, and facilitating provisioning. In this talk, I will illustrate how we study the delay performance in cloud computing systems from different modeling perspectives. First, I will focus on the delay of jobs that consist of multiple tasks, where the tasks can be processed in parallel on different servers, and a job is completed only when all its tasks are completed. Such jobs with parallel tasks are prevalent in today’s cloud computing systems. While the delay of individual tasks has been extensively studied, job delay has not been well-understood, even though job delay is the most important metric of interest to end users. In our work, we establish a stochastic upper bound on job delay using properties of associated random variables, and show its tightness in an asymptotic regime where the number of servers in the system and the number of tasks in a job both become large. After this, I will also briefly summarize our results on delay characterization for data-processing tasks where the locality of data needs to be considered, and for data transfer in large-scale datacenter networks.<br />

http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=115452&date=2018-02-26
Abstract: One of the greatest successes of computational complexity theory is the classification of countless fundamental computational problems into polynomial-time and NP-hard ones, two classes that are often referred to as tractable and intractable, respectively. However, this crude distinction of algorithmic efficiency is clearly insufficient when handling today's large scale of data. We need a finer-grained design and analysis of algorithms that pinpoints the exact exponent of polynomial running time, and a better understanding of when a speed-up is not possible. Over the years, many polynomial-time approximation algorithms were devised as an approach to bypass the NP-hardness obstacle of many discrete optimization problems. This area has developed into a rich field producing many algorithmic ideas and has lead to major advances in computational complexity. So far, however, a similar theory for high polynomial time problems to understand the trade-off between quality and running time is vastly lacking. <br />
<br />
In this presentation, I will give you an overview of the newly growing field of fine-grained algorithms and complexity, and my contributions therein. This will include fundamental problems such as edit distance computation, all-pairs shortest paths, parsing and matrix multiplication. They have applications ranging from genomics to statistical natural language processing, machine learning and optimization. I will show how as a natural byproduct of improved time complexity, one may design algorithms that are highly parallel as well as streaming algorithms with sublinear space complexity. Finally, motivated by core machine learning applications, I will discuss alternative measures of efficiency that may be equally relevant as time complexity.<br />

http://events.berkeley.edu/index.php/calendar/sn/IEOR.html?event_ID=116947&date=2018-04-16
Abstract: Reinforcement Learning (RL) is concerned with solving sequential decision-making problems in the presence of uncertainty. RL is really about two problems together. The first is the `Bellman problem’: Finding the optimal policy given the model, which may involve large state spaces. Various approximate dynamic programming and RL schemes have been developed, but either there are no guarantees, or they are not universal, or rather slow. In fact, most RL algorithms have become synonymous with stochastic approximation schemes that are known to be rather slow. This is an even more difficult problem for MDPs with continuous state (and action) spaces. We present a class of RL algorithms for the continuous state space problem based on `empirical’ ideas, which are simple, effective and yet universal with probabilistic guarantees. The idea involves randomized Kernel-based function fitting combined with `empirical’ updates. The key is a “probabilistic contraction analysis” method we have developed for analysis of stochastic iterative algorithms, wherein we show convergence to a probabilistic fixed point of a sequence of random operators via a stochastic dominance argument. <br />
<br />
The second RL problem is the `online learning (or the Lai-Robbins) problem’ when the model itself is unknown. We propose a simple posterior sampling-based regret-minimization reinforcement learning algorithm for MDPs. It achieves O(sqrt{T})-regret which is order-optimal. It not only optimally manages the “exploration versus exploitation tradeoff” but also obviates the need for expensive computation for exploration. The algorithm differs from classical adaptive control in its focus on non-asymptotic regret optimality as opposed to asymptotic stability. This seems to resolve a long standing open problem in Reinforcement Learning.<br />
