We present new practical local differentially private heavy hitters algorithms achieving optimal or near-optimal worst-case error and running time -- TreeHist and Bitstogram. In both algorithms, server running time is $ ilde O(n)$ and user running time is $ ilde O(1)$, hence improving on the prior state-of-the-art result of Bassily and Smith [STOC 2015] requiring $O(n^{5/2})$ server time and $O(n^{3/2})$ user time. With a typically large number of participants in local algorithms (in the millions), this reduction in time complexity, in particular at the user side, is crucial for making locally private heavy hitters algorithms usable in practice. We implemented Algorithm TreeHist to verify our theoretical analysis and compared its performance with the performance of Google's RAPPOR code.

Stochastic gradient Langevin dynamics (SGLD) is a fundamental algorithm in stochastic optimization. Recent work by Zhang et al. (2017) presents an analysis for the hitting time of SGLD for the first and second order stationary points. The proof in Zhang et al. (2017) is a two-stage procedure through bounding the Cheeger's constant, which is rather complicated and leads to loose bounds. In this paper, using intuitions from stochastic differential equations, we provide a direct analysis for the hitting times of SGLD to the first and second order stationary points. Our analysis is straightforward. It only relies on basic linear algebra and probability theory tools. Our direct analysis also leads to tighter bounds comparing to Zhang et al. (2017) and shows the explicit dependence of the hitting time on different factors, including dimensionality, smoothness, noise strength, and step size effects. Under suitable conditions, we show that the hitting time of SGLD to first-order stationary points can be dimension-independent. Moreover, we apply our analysis to study several important online estimation problems in machine learning, including linear regression, matrix factorization, and online PCA.

Abstract:
In a mathematical approach to hypothesis tests, we start with a clearly defined set of hypotheses and choose the test with the best properties for those hypotheses. In practice, we often start with less precise hypotheses. For example, often a researcher wants to know which of two groups generally has the larger responses, and either a t-test or a Wilcoxon-Mann-Whitney (WMW) test could be acceptable. Although both t-tests and WMW tests are usually associated with quite different hypotheses, the decision rule and p-value from either test could be associated with many different sets of assumptions, which we call perspectives. It is useful to have many of the different perspectives to which a decision rule may be applied collected in one place, since each perspective allows a different interpretation of the associated p-value. Here we collect many such perspectives for the two-sample t-test, the WMW test and other related tests. We discuss validity and consistency under each perspective and discuss recommendations between the tests in light of these many different perspectives. Finally, we briefly discuss a decision rule for testing genetic neutrality where knowledge of the many perspectives is vital to the proper interpretation of the decision rule.

Simplicity is the ultimate sophistication. Differentiable Architecture Search (DARTS) has now become one of the mainstream paradigms of neural architecture search. However, it largely suffers from several disturbing factors of optimization process whose results are unstable to reproduce. FairDARTS points out that skip connections natively have an unfair advantage in exclusive competition which primarily leads to dramatic performance collapse. While FairDARTS turns the unfair competition into a collaborative one, we instead impede such unfair advantage by injecting unbiased random noise into skip operations' output. In effect, the optimizer should perceive this difficulty at each training step and refrain from overshooting on skip connections, but in a long run it still converges to the right solution area since no bias is added to the gradient. We name this novel approach as NoisyDARTS. Our experiments on CIFAR-10 and ImageNet attest that it can effectively break the skip connection's unfair advantage and yield better performance. It generates a series of models that achieve state-of-the-art results on both datasets.

Recent advancements in diagnostic learning and development of gesture-based human machine interfaces have driven surface electromyography (sEMG) towards significant importance. Analysis of hand gestures requires an accurate assessment of sEMG signals. The proposed work presents a novel sequential master-slave architecture consisting of deep neural networks (DNNs) for classification of signs from the Indian sign language using signals recorded from multiple sEMG channels. The performance of the master-slave network is augmented by leveraging additional synthetic feature data generated by long short term memory networks. Performance of the proposed network is compared to that of a conventional DNN prior to and after the addition of synthetic data. Up to 14% improvement is observed in the conventional DNN and up to 9% improvement in master-slave network on addition of synthetic data with an average accuracy value of 93.5% asserting the suitability of the proposed approach.

An important component of every country's COVID-19 response is fast and efficient testing -- to identify and isolate cases, as well as for early detection of local hotspots. For many countries, producing a sufficient number of tests has been a serious limiting factor in their efforts to control COVID-19 infections. Group testing is a well-established mathematical tool, which can provide a serious and rapid improvement to this situation. In this note, we compare several well-established group testing schemes in the context of qPCR testing for COVID-19. We include example calculations, where we indicate which testing architectures yield the greatest efficiency gains in various settings. We find that for identification of individuals with COVID-19, array testing is usually the best choice, while for estimation of COVID-19 prevalence rates in the total population, Gibbs-Gower testing usually provides the most accurate estimates given a fixed and relatively small number of tests. This note is intended as a helpful handbook for labs implementing group testing methods.

Abstract:
Testing for white noise is a classical yet important problem in statistics, especially for diagnostic checks in time series modeling and linear regression. For high-dimensional time series in the sense that the dimension $p$ is large in relation to the sample size $T$, the popular omnibus tests including the multivariate Hosking and Li–McLeod tests are extremely conservative, leading to substantial power loss. To develop more relevant tests for high-dimensional cases, we propose a portmanteau-type test statistic which is the sum of squared singular values of the first $q$ lagged sample autocovariance matrices. It, therefore, encapsulates all the serial correlations (up to the time lag $q$) within and across all component series. Using the tools from random matrix theory and assuming both $p$ and $T$ diverge to infinity, we derive the asymptotic normality of the test statistic under both the null and a specific VMA(1) alternative hypothesis. As the actual implementation of the test requires the knowledge of three characteristic constants of the population cross-sectional covariance matrix and the value of the fourth moment of the standardized innovations, nontrivial estimations are proposed for these parameters and their integration leads to a practically usable test. Extensive simulation confirms the excellent finite-sample performance of the new test with accurate size and satisfactory power for a large range of finite $(p,T)$ combinations, therefore, ensuring wide applicability in practice. In particular, the new tests are consistently superior to the traditional Hosking and Li–McLeod tests.

Abstract:
Conditioning stable Lévy processes on zero probability events recently became a tractable subject since several explicit formulas emerged from a deep analysis using the Lamperti transformations for self-similar Markov processes. In this article, we derive new harmonic functions and use them to explain how to condition stable processes to hit continuously a compact interval from the outside.

Abstract:
Nonparametric Bayesian inference has seen a rapid growth over the last decade but only few nonparametric Bayesian approaches to time series analysis have been developed. Most existing approaches use Whittle’s likelihood for Bayesian modelling of the spectral density as the main nonparametric characteristic of stationary time series. It is known that the loss of efficiency using Whittle’s likelihood can be substantial. On the other hand, parametric methods are more powerful than nonparametric methods if the observed time series is close to the considered model class but fail if the model is misspecified. Therefore, we suggest a nonparametric correction of a parametric likelihood that takes advantage of the efficiency of parametric models while mitigating sensitivities through a nonparametric amendment. We use a nonparametric Bernstein polynomial prior on the spectral density with weights induced by a Dirichlet process and prove posterior consistency for Gaussian stationary time series. Bayesian posterior computations are implemented via an MH-within-Gibbs sampler and the performance of the nonparametrically corrected likelihood for Gaussian time series is illustrated in a simulation study and in three astronomy applications, including estimating the spectral density of gravitational wave data from the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO).

Washington, D.C. Newsroom, May 7, 2020 / 02:40 pm (CNA).- The governor of Illinois has said he will continue to ban public gatherings of more than 50 people—including religious services—until a vaccine or treatment for coronavirus is available.

The announcement comes as the White House is reported to have shelved guidance from the Centers for Disease Control on gradually reopening sections of the American economy and society.

Illinois governor J.B. Pritzker announced Wednesday that gatherings of more than 50 people in the state would not be allowed until a coronavirus vaccine “or highly effective treatment” is “widely available.”

Public health officials, including Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, have cautioned that a COVID-19 vaccine is at least 12 to 18 months from being developed and made available.

According to Pritzker’s five-part plan for reopening the state, gatherings of ten or fewer people are not even allowed until phase 3, the “recovery” phase that can begin, at earliest, May 29. However, following a lawsuit last week, the governor has allowed citizens to leave their homes for religious services as long as ten or fewer people are gathered for worship.

Previously, religious services of any kind in the state—including drive-in and in-person services—were curtailed during the pandemic, and even other forms of sacramental practice such as drive-in confessions were not allowed.

The Archdiocese of Chicago announced on May 1 that public Masses with 10 or fewer people would resume.

Other dioceses across the United States have already begun rolling back total suspensions on the public celebration of Mass. 

Last week, CNA reported that the White House Domestic Policy Council held a series of conference calls with bishops who had begun the process of reopening churches in line with local public health orders.

During the calls, administration officials expressed their hope to be able to support faith communities with “sensitive and respectful guidance” to help restore public worship “as soon as it is feasible.”

The bishops were told that the Centers for Disease Control hoped that issuing guidance could help inform state and local leaders about the “essential” nature of religious practice, while still allowing for localized responses to the coronavirus and provide “helpful parameters” for state and local governments who are trying to safeguard public health. But, on Thursday, AP reported that the Trump administration had shelved a 17-page report titled “Guidance for Implementing the Opening Up America Again Framework.”

That document included a section on “Interim Guidance for Communities of Faith.”

According to AP, CDC officials expected the guidance to be released at the end of last week but were instead told it “would never see the light of day.” 

Peter Breen, executive director of the Thomas More Society,  told CNA that “policymakers that are making plans based on the development of a vaccine or other cure to this coronavirus are engaging in magical thinking.”

“While there is always a possibility that some miracle cure may emerge, that is entirely uncertain and should not be the basis for setting policy, especially policy in relation to our communities of faith,” Breen stated.

On April 30, the Thomas More Society filed a lawsuit on behalf of The Beloved Church in Lena, Illinois, and by that night, attorney Peter Breen told CNA, a paragraph had been added to an executive order of Pritzker’s allowing for people to leave their home for religious services.

“He [Pritzker] has at least brought churches out of the abyss of ‘non-essential,’ but he has not fully elevated them to the heights of being an ‘essential’ business or operation,” Breen told CNA on Wednesday, noting that businesses deemed “essential” to remain open were not subject to the 10-person rule.

Washington D.C., May 7, 2020 / 04:30 pm (CNA).- The White House service for the National Day of Prayer on Thursday focused on protection from the coronavirus pandemic. President Trump said Americans will continue to pray for divine assistance as the nation faces “unforeseen and seemingly unbearable hardships.”

Sister Eneyda Martinez of the Poor Sisters of St. Joseph community in Alexandria, Virginia was one of the religious leaders present to lead attendees in prayer.

“Merciful Savior, heal and comfort the sick so that with health restored, they may give you praise. Divine Physician, accompany our caregivers, so that serving you with patience they may heal wisely. And through wisdom, guide our leaders, so that through seeking remedies they may follow your light,” Sister Eneyda Martinez prayed at the service in the White House’s Rose Garden.

The National Day of Prayer was designated by Congress in 1952, and scheduled in 1988 to be observed annually on the first Thursday in the month of May.

In attendance at the White House service were President Trump and First Lady Melania Trump, as well as Vice President Mike Pence and Second Lady Karen Pence, and Paula White, and other religious leaders from Catholic, Christian, and Mormon churches, and Jewish and Hindu faiths.

The prayer service emphasized prayer for protection from the coronavirus pandemic, as well as prayer for the sick and their families, and health care workers.

“Christ, the Anointed, protect us in body and in spirit, so that free from harm we may be delivered from all affliction,” prayed Sister Eneyda Martinez.

Vice President Pence urged Americans to be “persistent in prayer,” especially for the families of the dead, those sick with the virus, and health care workers, many who have “literally taken the place of loved ones” in being the only close contacts of COVID-19 patients.

On Thursday morning, Trump issued a proclamation, noting the importance of prayer during the pandemic.

“During the past weeks and months, our heads have bowed at places outside of our typical houses of worship, whispering in silent solitude for God to renew our spirit and carry us through unforeseen and seemingly unbearable hardships,” Trump stated.

“Even though we have been unable to gather together in fellowship with our church families, we are still connected through prayer and the calming reassurance that God will lead us through life's many valleys.”

The U.S. Centers for Disease Control was reportedly drafting guidance for states to reopen public accommodations and religious services, but according to the Associated Press on Thursday, the document was buried by the administration.

That document reportedly advised against churches holding services if they were not in a “community no longer requiring significant mitigation.”

However, if that and other certain conditions were in place, churches should take precautions such as ensuring social distancing, wearing of masks by congregants, and intensifying cleaning of churches, the CDC document reportedly said.

State orders have varied in their restrictions on public gatherings during the pandemic; a Kansas stay-at-home order allowed religious gatherings of 10 or fewer people, while Illinois prohibited all religious gatherings.

After every U.S. diocese stopped public Masses during March, Catholic dioceses have started offering public Masses, beginning with the diocese of Las Cruces, New Mexico, with several other dioceses following suit in ensuing days.

Officials from the CDC and the White House spoke with four of the bishops on April 28 and 29 about the resumption of public religious services.

CNA Staff, May 5, 2020 / 03:01 pm (CNA).- At least 51 workers have been infected with the novel coronavirus at the Grasberg mine in Indonesia, the world’s largest gold mine.

Nine employees of Freeport McMoRan, the organization who operates the mine, have been hospitalized due to COVID-19 and another 42 have been forced into quarantine, UCA News reported May 5.

The mine is located in Papua and is known for its production of gold and copper. The operation includes around 20,000 employees.

Riza Pratama, vice president of Freeport, said the company will fully cooperate with the government's coronavirus task force but will continue mining operations to support the national economy. He said the company will prioritize the health and safety of workers and will conduct regular health screenings, implement social distancing, provide a quarantine area for employees, according to UCA News.

Father Ansel Amo, who heads the Justice, Peace, and Integrity of Creation Commission for the Archdiocese of Merauke, said these measures are not enough to protect workers.

“Freeport management should limit workers’ activities so that they don’t transmit the disease to other people, including local people. They should stop its operations temporarily,” he told UCA News.

Indonesia has seen more than 12,000 cases from the coronavirus, leading to 872 reported deaths as of May 5. Globally, more than 3.7 million cases of the virus have been reported, and a quarter of a million deaths.
