06/2020: What is the best feasible direction of descent for constrained minimization? Does it get linear convergence, with rate independent of geometric constants (like pyramidal width)? Check out our latest research that partially answers these questions: Walking in the Shadow: A New Perspective on Descent Directions for Constrained Minimization – joint work with Hassan Mortagy and Sebastian Pokutta. abstract
Descent directions such as movement towards Frank-Wolfe vertices, away steps, in-face away steps and pairwise directions have been an important design consideration in conditional gradient descent (CGD) variants. In this work, we attempt to demystify the impact of movement in these directions towards attaining constrained minimizers. The best local direction of descent is the directional derivative of the projection of the gradient, which we refer to as the shadow of the gradient. We show that the continuous-time dynamics of moving in the shadow are equivalent to those of PGD however non-trivial to discretize. By projecting gradients in PGD, one not only ensures feasibility but also is able to “wrap” around the convex region. We show that Frank-Wolfe (FW) vertices in fact recover the maximal wrap one can obtain by projecting gradients, thus providing a new perspective to these steps. We also claim that the shadow steps give the best direction of descent emanating from the convex hull of all possible away-vertices. Opening up the PGD movements in terms of shadow steps gives linear convergence, dependent on the number of faces. We combine these insights into a novel Shadow-CG method that uses FW steps (i.e., wrap around the polytope) and shadow steps (i.e., optimal local descent direction), while enjoying linear convergence. Our analysis develops properties of directional derivatives of projections (which may be of independent interest), while providing a unifying view of various descent directions in the CGD literature.
06/2020: Online learning frameworks often operate under the assumption that the feedback from an action takes a fixed (unit) amount of time, but what if the time for feedback is also stochastic? Can we learn the best group of users (arms) to allocate jobs to, so that the rate of reward is maximized? Can we also ensure “some” fairness in allocation? In a recent work: Group-fair Online Allocation in Continuous Time, jointly with Semih Cayci and Atilla Eryilmaz, we develop fair online allocation policies under stochastic times for task completion.

04/2020: What is the impact of bias in student application evaluations in college admissions? Can we quantify the impact on students to know who’s impact the most? How should we distribute limited resources to reduce disparate impact? Check out our latest draft on quantifying the Impact of Bias on School Admissions and Targeted Interventions, joint work with Yuri Faenza and Xuan Zhang.
abstractWe show that under a natural matching mechanism, the ranking of the matched schools of both unbiased group and biased group of students are affected, with some of the latter being heavily penalized even for relatively small bias. Further, we find that schools have little incentive to change their evaluation mechanism, if their goal is the maximize the total potential of accepted students. Armed with this basic model and inferences, we show that the students who are most in need of additional resources to achieve their true potential are average-performing students, as opposed to high performers, thus questioning existing scholarship/aide mechanisms focusing on top performers. We further show, using computational experiments, that the qualitative take-aways from our model remain the same even if some of the assumptions are relaxed and we move, e.g., from a continuous to a discrete model and allow the bias factor to vary for each student.

02/2020: Our paper on “Too many fairness metrics: Is there a solution?” got accepted to Ethics of Data Science Conference 2020, Sydney! Congratulations Gireeja, Akhil, Helen and Simon!
abstractTo demonstrate our framework, we consider the placement of emergency rooms in two neighboring California counties. We consider “fairness” with respect to different groups of people (e.g. grouped by race, income etc.). The distance traveled an emergency room for groups of people is the basis of the fairness metrics, and there are at least 24 group metrics of fairness in the literature. In this, one must ensure equity across multiple groupings of the population. For example, it is important to simultaneously consider equity across both racial groups as well as across economic groups.
In this paper we discuss: (i) a problem formulation with composite objectives that capture interplay of equity and efficiency, (ii) problem instances when two or more equity metrics can be simultaneously minimized, (iii) solutions that are approximately-optimal for multiple definitions of fairness simultaneously. We find that in practice, rather than deciding on a single equity metric, one can compute approximately-optimal solutions that may not be perfect with respect to any single metric, yet can be near-perfect with respect to multiple metrics. We hope that these tools can be useful for policymakers to find operational solutions amidst the myriad of fairness definitions.
