An Illuminating Algorithm for the Light Bulb Problem. (arXiv:1810.06740v1 [cs.DS])

Wednesday, October 17, 01:30 UTC @ cs.DS updates on arXiv.org

The Light Bulb Problem is one of the most basic problems in data analysis. One is given as input $n$ vectors in $\{-1,1\}^d$, which are all independently and uniformly random, except for a planted pair of vectors with inner product at least $\rho \cdot d$ for some constant $\rho > 0$. The task is to find the planted pair. The most straightforward algorithm leads to a runtime of $\Omega(n^2)$. Algorithms based on techniques like Locality-Sensitive Hashing achieve runtimes of $n^{2 - O(\rho)}$; as $\rho

Learning-Theoretic Foundations of Algorithm Configuration for Combinatorial Partitioning Problems. (arXiv:1611.04535v4 [cs.DS] UPDATED)

Wednesday, October 17, 01:30 UTC @ cs.DS updates on arXiv.org

Max-cut, clustering, and many other partitioning problems that are of significant importance to machine learning and other scientific fields are NP-hard, a reality that has motivated researchers to develop a wealth of approximation algorithms and heuristics. Although the best algorithm to use typically depends on the specific application domain, a worst-case analysis is often used to compare algorithms. This may be misleading if worst-case instances occur infrequently, and thus there is a demand for opti

A Tight Extremal Bound on the Lov\'{a}sz Cactus Number in Planar Graphs. (arXiv:1804.03485v2 [cs.DM] UPDATED)

Wednesday, October 17, 01:30 UTC @ cs.DS updates on arXiv.org

A cactus graph is a graph in which any two cycles are edge-disjoint. We present a constructive proof of the fact that any plane graph $G$ contains a cactus subgraph $C$ where $C$ contains at least a $\frac{1}{6}$ fraction of the triangular faces of $G$. We also show that this ratio cannot be improved by showing a tight lower bound. Together with an algorithm for linear matroid parity, our bound implies two approximation algorithms for computing "dense planar structures" inside any graph: (i) A $\frac{1}{

Bounding Entities within Dense Subtensors. (arXiv:1810.06230v2 [cs.DS] UPDATED)

Wednesday, October 17, 01:30 UTC @ cs.DS updates on arXiv.org

Group-based fraud detection is a promising methodology to catch frauds on the Internet because 1) it does not require a long activity history for a single user; and 2) it is difficult for fraudsters to avoid due to their economic constraints. Unfortunately, existing work does not cover the entire picture of a fraud group: they either focus on the grouping feature based on graph features like edge density, or probability-based features, but not both. To our knowledge, we are the first to combine these fea

Multi-budgeted directed cuts. (arXiv:1810.06848v1 [cs.DS])

Wednesday, October 17, 01:30 UTC @ cs.DS updates on arXiv.org

We study multi-budgeted variants of the classic minimum cut problem and graph separation problems that turned out to be important in parameterized complexity: Skew Multicut and Directed Feedback Arc Set. In our generalization, we assign colors $1,2,...,\ell$ to some edges and give separate budgets $k_{1},k_{2},...,k_{\ell}$. Let $E_{i}$ be the set of edges of color $i$. The solution $C$ for the multi-budgeted variant of a graph separation problem not only needs to satisfy the usual separation requirement

Eliminating Higher-Multiplicity Intersections, III. Codimension 2. (arXiv:1511.03501v5 [math.GT] UPDATED)

Wednesday, October 17, 01:30 UTC @ cs.CG updates on arXiv.org

We study conditions under which a finite simplicial complex $K$ can be mapped to $\mathbb R^d$ without higher-multiplicity intersections. An almost $r$-embedding is a map $f: K\to \mathbb R^d$ such that the images of any $r$ pairwise disjoint simplices of $K$ do not have a common point. We show that if $r$ is not a prime power and $d\geq 2r+1$, then there is a counterexample to the topological Tverberg conjecture, i.e., there is an almost $r$-embedding of the $(d+1)(r-1)$-simplex in $\mathbb R^d$. This i

Online Coloring of Short Intervals. (arXiv:1802.09503v3 [math.CO] UPDATED)

Wednesday, October 17, 01:30 UTC @ cs.DS updates on arXiv.org

We study the online graph coloring problem restricted to the intersection graphs of intervals with lengths in $[1,\sigma]$. For $\sigma=1$ it is the class of unit interval graphs, and for $\sigma=\infty$ the class of all interval graphs. Our focus is on intermediary classes. We present a $(1+\sigma)$-competitive algorithm, which beats the state of the art for $1 < \sigma < 2$. For $\sigma = 1$ our algorithm matches the performance of FirstFit, which is $2$-competitive for unit interval grap

Semitotal Domination: New hardness results and a polynomial-time algorithm for graphs of bounded mim-width. (arXiv:1810.06872v1 [cs.CC])

Wednesday, October 17, 01:30 UTC @ cs.CC updates on arXiv.org

A semitotal dominating set of a graph $G$ with no isolated vertex is a dominating set $D$ of $G$ such that every vertex in $D$ is within distance two of another vertex in $D$. The minimum size $\gamma_{t2}(G)$ of a semitotal dominating set of $G$ is squeezed between the domination number $\gamma(G)$ and the total domination number $\gamma_{t}(G)$. \textsc{Semitotal Dominating Set} is the problem of finding, given a graph $G$, a semitotal dominating set of $G$ of size $\gamma_{t2}(G)$. In this pap

Randomized contractions meet lean decompositions. (arXiv:1810.06864v1 [cs.DS])

Wednesday, October 17, 01:30 UTC @ cs.DS updates on arXiv.org

The randomized contractions technique, introduced by Chitnis et al. in 2012, is a robust framework for designing parameterized algorithms for graph separation problems. On high level, an algorithm in this framework recurses on balanced separators while possible, and in the leaves of the recursion uses high connectivity of the graph at hand to highlight a solution by color coding. In 2014, a subset of the current authors showed that, given a graph $G$ and a budget $k$ for the cut size in the studi

Sharp Analysis of Learning with Discrete Losses. (arXiv:1810.06839v1 [cs.LG])

Wednesday, October 17, 01:30 UTC @ cs.CC updates on arXiv.org

The problem of devising learning strategies for discrete losses (e.g., multilabeling, ranking) is currently addressed with methods and theoretical analyses ad-hoc for each loss. In this paper we study a least-squares framework to systematically design learning algorithms for discrete losses, with quantitative characterizations in terms of statistical and computational complexity. In particular we improve existing results by providing explicit dependence on the number of labels for a wide class of losses

The Computational Complexity of Training ReLU(s). (arXiv:1810.04207v2 [cs.CC] UPDATED)

Wednesday, October 17, 01:30 UTC @ cs.CC updates on arXiv.org

We consider the computational complexity of training depth-2 neural networks composed of rectified linear units (ReLUs). We show that, even for the case of a single ReLU, finding a set of weights that minimizes the squared error (even approximately) for a given training set is NP-hard. We also show that for a simple network consisting of two ReLUs, the error minimization problem is NP-hard, even in the realizable case. We complement these hardness results by showing that, when the weights and samples bel

Minimizing Sum of Non-Convex but Piecewise log-Lipschitz Functions using Coresets. (arXiv:1807.08446v2 [cs.LG] UPDATED)

Wednesday, October 17, 01:30 UTC @ cs.CG updates on arXiv.org

We suggest a new optimization technique for minimizing the sum $\sum_{i=1}^n f_i(x)$ of $n$ non-convex real functions that satisfy a property that we call piecewise log-Lipschitz. This is by forging links between techniques in computational geometry, combinatorics and convex optimization. Example applications include the first constant-factor approximation algorithms whose running-time is polynomial in $n$ for the following fundamental problems: (i) Constrained $\ell_z$ Linear Regression:

A Topological Regularizer for Classifiers via Persistent Homology. (arXiv:1806.10714v3 [cs.LG] UPDATED)

Wednesday, October 17, 01:30 UTC @ cs.CG updates on arXiv.org

Regularization plays a crucial role in supervised learning. Most existing methods enforce a global regularization in a structure agnostic manner. In this paper, we initiate a new direction and propose to enforce the structural simplicity of the classification boundary by regularizing over its topological complexity. In particular, our measurement of topological complexity incorporates the importance of topological features (e.g., connected components, handles, and so on) in a meaningful manner, and provi

Polynomial-time algorithm for Maximum Weight Independent Set on $P_6$-free graphs. (arXiv:1707.05491v2 [cs.DS] CROSS LISTED)

Wednesday, October 17, 01:30 UTC @ cs.DS updates on arXiv.org

In the classic Maximum Weight Independent Set problem we are given a graph $G$ with a nonnegative weight function on vertices, and the goal is to find an independent set in $G$ of maximum possible weight. While the problem is NP-hard in general, we give a polynomial-time algorithm working on any $P_6$-free graph, that is, a graph that has no path on $6$ vertices as an induced subgraph. This improves the polynomial-time algorithm on $P_5$-free graphs of Lokshtanov et al. (SODA 2014), and the quasipolynomi

On Finding Dense Subgraphs in Bipartite Graphs: Linear Algorithms with Applications to Fraud Detection. (arXiv:1810.06809v1 [cs.DS])

Wednesday, October 17, 01:30 UTC @ cs.DS updates on arXiv.org

Detecting dense subgraphs from large graphs is a core component in many applications, ranging from social networks mining, bioinformatics, to online fraud detection. In this paper, we focus on mining dense subgraphs in a bipartite graph. The work is motivated by the task of fraud detection that can often be formulated as mining a bipartite graph formed by the source nodes (followers, customers) and target nodes (followees, products, etc.) for malicious patterns. We introduce a new restricted biclique pro

Segment representations with small resolution. (arXiv:1810.07072v1 [cs.CG])

Wednesday, October 17, 01:30 UTC @ cs.CG updates on arXiv.org

A segment representation of a graph is an assignment of line segments in 2D to the vertices in such a way that two segments intersect if and only if the corresponding vertices are adjacent. Not all graphs have such segment representations, but they exist, for example, for all planar graphs. In this note, we study the resolution that can be achieved for segment representations, presuming the ends of segments must be on integer grid points. We show that any planar graph (and more generally, any gra

Efficient Synchronization of State-based CRDTs. (arXiv:1803.02750v2 [cs.DC] UPDATED)

Wednesday, October 17, 01:30 UTC @ cs.DS updates on arXiv.org

To ensure high availability in large scale distributed systems, Conflict-free Replicated Data Types (CRDTs) relax consistency by allowing immediate query and update operations at the local replica, with no need for remote synchronization. State-based CRDTs synchronize replicas by periodically sending their full state to other replicas, which can become extremely costly as the CRDT state grows. Delta-based CRDTs address this problem by producing small incremental states (deltas) to be used in synchronizat

Dieter Bohn, writing at The Verge: That’s the idea behind the new Palm phone. It’s a sidecar for your phone. You should almost think of it more as a thing to get instead of a connected smartwatch than as a second phone. In fact, thinking of it as a smartwatch is a good move since that’s precisely how Verizon (and only Verizon) is selling it: as an add-on for existing plans. You can’t just go buy the thing on its own or unlocked as your primary phone. It

Rust build platforms for Android hardware

Dear Dr B: What do you actually live from?

I was indeed unemployed for two months last year, not because I said rude things about other people’s theories, but simply because someone forgot to renew my contract. Or maybe I forgot to ask that it be renewed. Or

We make sure that everything works as expected, and only then do we refactor the code to be more Swift-like. As an example, on the Episode page we show the user one of four things: “Become a subscriber to download

A stability theorem on cube tessellations

It is shown that if a $d$-dimensional cube is decomposed into $n$ cubes, the side lengths of which belong to the interval $(1 − \frac{n}{1/d 1 +1} , 1]$, then $n$ is a perfect $d$-th power and all cubes are of the same size. This result is essentially tight.

John Paczkowski and Charlie Warzel, reporting for BuzzFeed: “We tried to figure out if there was anything, anything, that transpired that’s even remotely close to this,” a senior Apple security executive told BuzzFeed News. “We found nothing.” A senior security engineer directly involved in Apple’s internal investigation described it as “endoscopic”, noting they had never seen a chip like the one described in the story, let alone found one. “I don

Customizing the Infograph Face on Apple Watch Series 4

Friday, October 05, 13:54 UTC @ Daring Fireball

Zac Hall, writing at 9to5Mac: Infograph can show up to eight complications, but that doesn’t mean it must — even if the default version is fully loaded. For me, stripping Infograph down to just the clock is a great starting place. This requires a lot of Digital Crown scrolling on the Apple Watch to set each complication slot to empty and may be faster on the Watch app for iPhone. The end result is a simple and attractive clock without all of the noise of complications r

In Swift, we often have the choice: do we want to express a piece of logic in an imperative or in a functional way? As a simple example, we’ll sum up the total width of an array of views: var width: CGFl

Building a Form Library

Tuesday, September 11, 00:00 UTC @ objc.io

Over the last few weeks we have completed a series of ten Swift Talk episodes following the process of building a declarative form library. For those who haven’t been following along, we’d like to take this opportunity to revisit our original design goals and give you an idea of what this library is already capable of. When we started to build the library, we had two major design goals in mind: Forms

Density of the Great Pacific Garbage Patch

Monday, September 10, 19:21 UTC @ John D. Cook

The Great Pacific Garbage Patch (GPGP) is a huge region of ocean trash twice the area of Texas. I’m trying to understand how dense it is, and running into contradictory information. This article describes a project, Ocean Cleanup, that aims to clean up half the GPGP in five years. How could you possibly clean up […]

Adding Padding To A Stack View

Monday, September 10, 18:42 UTC @ Use Your Loaf

How do you add padding internal to a stack view? How about when the stack view has readable content and you want to limit the line length? You can do it in Interface Builder or in code but both have oddities. Stack view readable content guides certainly don’t work the way I would expect or hope. (Also read to the end for a special announcement…) Stack View Margins The whole point of a stack view is that it creates the constraints for its arr

Tragedy of the Commons Clause

Hello World: A short review

Monday, September 10, 06:19 UTC @ The Geomblog

A short review of Hannah Fry's new book 'Hello World' Starting wth Cathy O'Neill's Weapons of Math Destruction, there's been an onslaught of books sounding the alarm about the use of algorithms in daily life. My Amazon list that collects these together is even called 'Woke CS'. These are all excellent books, calling out the racial, gender, and class inequalities that algorithmic decision-making can and does exacerbate and the role of Silicon Valley in perpetuating these biases.

Enough group theory for now

Sunday, September 09, 23:11 UTC @ John D. Cook

I’ve written three blog posts lately about the classification of finite simple groups. I’m done with that topic for now. I may come back and revisit it in the future. So if group theory isn’t your favorite topic, don’t worry. I don’t know what I’ll blog about next, but it’ll probably be one of the […]

Overlap in the classification of finite simple groups

Sunday, September 09, 19:14 UTC @ John D. Cook

The previous post defined the groups PSL(n, q) where n is a positive integer and q is a prime power. These are finite simple groups for n ≥ 2 except for PSL(2, 2) and PSL(2, 3). Overlap among PSL(n, q) There are a couple instances where different values of n and q lead to isomorphic groups: PSL(2, 4) and PSL(2, 5) are […]

Planar and poly-arc Lombardi drawings

Friday, September 07, 14:01 UTC @ Journal of Computational Geometry

In Lombardi drawings of graphs, edges are represented as circular arcs and the edges incident on vertices have perfect angular resolution. It is known that not every planar graph has a planar Lombardi drawing. We give an example of a planar 3-tree that has no planar Lombardi drawing and we show that all outerpaths do have a planar Lombardi drawing. Further, we show that there are graphs that do not even have any Lombardi drawing at all. With this in mind, we generalize the notion of Lombardi drawings to

On compositionality

Friday, September 07, 09:53 UTC @ Lambda the Ultimate - Programming Languages Weblog

Jules Hedges has written a thought-provoking blog post, On compositionality where he connects the familiar idea of compositionality to the idea of emergent effects in nature, where systems can be understood as either having compositional properties or emergent properties. The key point about emergent systems is that they are hard to understand, and this is as true for engineering as it is for science. He goes on to say "As a final

Are Conferences Discriminatory?

Thursday, September 06, 13:01 UTC @ Computational Complexity

Glencora Borradaile wrote a blog post in June about how conferences discriminate. Let me spell it out. In order to really succeed in most areas of computer science, you need to publish conference papers and this, for the most part, means attendance at those conferences. But because of the institutional discrimination of border control laws and the individual d

GitHub workspaces using email

In my effort of moving away form Gmail, I took the opportunity to set up my new email account in such a way that I could better organize my work on GitHub. There’s a feature that GitHub has never had and that I’d find very useful, workspaces. I used to look at the notifications to know the things I should focus on. If you are part of multiple organizations, all those notifications show up in the same place. As a result, when I open the notifications page to plan the open source work, I end up

Superfluid dark matter passes another check: strong gravitational lensing

Wednesday, September 05, 16:49 UTC @ Backreaction

The idea that it’s made of particles that interact so weakly we haven’t yet measured them works well to explain some of the observational evidence. Notably the motions of galaxies bound to clusters and the features of the cosmic microwave background fit with theories of particle dark matter

Placing your coins on a shelf

Wednesday, September 05, 14:13 UTC @ Journal of Computational Geometry

We consider the problem of packing a family of disks ``on a shelf,'' that is, such that each disk touches the x-axis from above and such that no two disks overlap. We study the problem of minimizing the distance between the leftmost point and the rightmost point of any disk in such a packing.  We show how to approximate this problem within a factor of 4/3 in O(n log n) time. We further provide an O(n log n)-time exact algorithm for a special case which includes inputs wh

Enums are a powerful tool, allowing you to create expressive and precise APIs. However, extracting associated values with a switch statement sometimes feels a little clunky. Consider the following example: enum Layout { case view(width: CGFloat) case space(width: CGFloat) case newline } Here, we’re modelling a UI layout: we can place either a view or a space on a line, both of which have an associated value for their width
