Uber adds public transportation to its app starting with Denver

first_img Mobile Tech Industry Mobile Apps Uber You may be able to use the Uber app to see when your bus is coming. On Thursday the ride-hailing giant rolled out its first integration with public transit. Users in Denver will now see end-to-end directions and real-time information for public transit in the app, thanks to a partnership with the Regional Transportation District. “Our customers want their trips to be as seamless as possible, and a collaboration like this one allows them to plan for travel from end to end, including additional first mile and last mile options,” said David Genova, CEO and general manager of RTD, in a blog post. “RTD is pleased to work with Uber as we present riders with additional, complementary options to most efficiently reach their destination.”This isn’t Uber’s first attempt to become the one-stop shop for transportation. In September, the company launched a new feature called Mode Switch, an in-app tool that lets people see what modes of transportation the company offers in that location, including cars, bikes and scooters. From there, users can choose what transportation they want to use. Uber CEO Dara Khosrowshahi said the ride-hailing giant wants “to be the Amazon of transportation.”Riders will see “Transit” next to UberX, Uber Pool and other available options from the ride-hailing company once they enter their destinations. When they select the option, they’ll be able to view available transit routes along with real-time departure and arrival times. Users will see walking directions to and from the transit stations. They’ll also soon be able to buy and use RTD tickets, Uber said.Uber integrated this public transportation information through a partnership with the urban mobility app Moovit, which provides real-time transit data and route planning around the world. Uber said that with this partnership it’ll expand the feature to more cities in coming months.First published Jan. 31, 11:56 a.m. PT.

Pop theatre Manto flavour of NSD fest

first_imgThe crossover between literature, performance, classicism and its modern interpretations will be on showcase at the 15th Bharat Rang Mahotsav, the National School of Drama’s (NSD) annual theatre festival.The festival will celebrate the legacy Saadat Hasan Manto, William Shakespeare and popular theatre in the perspective of the modern Indian stage.Announcing the 15-day theatre gala, NSD chairperson Amal Allana said the festival will bring to the Capital and twin venue of Jaipur a total of 87 plays, lectures, interactions, offsite projects and special packages. It will open with Also Read – ‘Playing Jojo was emotionally exhausting’Atmakatha, a two-hour play directed by Vinay Sharma, featuring former Bollywood actor Kulbhushan Kharbanda. It will mark the actor’s return to the stage, Allana said. ‘The wider variety of plays this year has allowed us to package them into categories. The ‘Manto section’ has six plays adapted from stories by Manto and the section on Shakespeare will explore the ‘inter-cultural influence on the dramatist’ with seven productions,’ Allana said, adding: ‘The focus will be on popular theatre that evolved from the Parsi form of theatre in the second half of 19th century.’ The 450 entries from which 87 were shortlisted were from across regions and genres that were not always ‘dependent on the government for support’.

The Shakespeare panorama will play host to the likes of indigenous improvisations of King Lear, a solo performance from Turkmenistan, an Assamese adaptation of Julius Caeser, a Hindi makeover of Twelfth Night, Piya Behroopia that played at the Globe Theatre in London last season, Footsbarn Theatre’s Indian Tempest as physical theatre. Wendy Jehlen of the US will present excerpts from Hamlet, Macbeth, Othello and Titus Andronicus in a choreographed non-verbal piece as The Knocking Within.A Malayalee adaptation, Yamadoothu: After the Death of Othello in Malayalam from Kerala, based on Shakespeare’s Othello will also be staged. Pointing to the trends in Indian contemporary theatre, Amal Allana said: ‘the trend to go back to traditional forms of theatre has waned’.‘We don’t have to go back to folk theatre and traditional theatre to sustain contemporary theatre. Plays are being staged as performances and devised scripts. There is more exchange and effort between theatre people because of greater a sense of participation and lack of original scripts,’ Allana said.She said: ‘The complexity of new theatre has brought in wake more non-verbal plays and physical theatre’. NSD director Anuradha Kapur said ‘there was a flowering of another kind of script that were meant to be read. We are reading scripts and performing them as well’. Bharat Rang mahotsav will feature plays divided into several categories.last_img read more

Aggressive driving a reflection of surrounding culture

first_imgAggressive driving behaviour is a reflection of a person’s surrounding culture, both on the road and on a broader social level, says a study.The findings suggest that some countries and cultures may be more susceptible to aggressive or competitive driving behaviours due to their social environment, and that improvements in that arena would also be seen in driving behaviour.“The choice to be competitive versus cooperative always starts with culture, by the influences around us and the way other people behave, ‘said one of the researchers Haizhong Wang, assistant professor of transportation engineering at Oregon State University in the US.  Also Read – ‘Playing Jojo was emotionally exhausting’“And it’s clear there’s a role for education and experience, where studies have shown the value of young drivers participating in driver education programmes and receiving positive guidance from their parents and peers,” Wang noted.The study also implies that different social conditions might ultimately translate into better drivers.However, these dangerous behaviours are becoming a worldwide phenomenon of almost epidemic proportions partly as a reaction to overcrowded road networks, the researchers said. Also Read – Leslie doing new comedy special with NetflixThe findings, published in the journal Procedia Engineering, showed that such behaviour is more pronounced in men than in women.The research was done with drivers in China where competitive driving is very common. The problems in China as it becomes increasingly crowded with drivers, however, reflect similar concerns at varying levels around the world, Wang said. In this analysis, the researchers concluded that drivers in congested situations generally believed that the chaotic traffic state was responsible for their competitive behaviour and they had no option other than to compete for space, the right-of-way, and gain advantages through speed and spacing.In simple terms, it was right and proper that they should try to keep up with or get ahead of traffic; that was the example being set for them, and they drove that way because everyone else did.However, the study also suggested that “personality traits draw on and are influenced by aspects of one’s social environment.” It is prevalent in India too where the surroundings play an important part.last_img read more

How Facebook data scientists use Bayesian optimization for tuning their online systems

first_imgFacebook data scientists had released a paper, Constrained Bayesian Optimization with Noisy Experiments in 2017 where they describe using Bayesian optimization to design rounds of A/B tests based on prior test results. An A/B test is a randomized experiment, used to determine which variant of A and B is more “effective”. They are used for improving a product. Facebook has a large array of backend systems serving billions of people every day. They have a large number of internal parameters that must be tuned carefully using live, randomized experiments, also known as A/B tests. Individual experiments may take a week or longer, so there is a challenge to optimize a set of parameters with the least number of experiments. Bayesian optimization Bayesian optimization is a technique used to solve optimization problems where the objective function (the online metric of interest) does not have an analytic expression. It can only be evaluated through some time consuming operations like a randomized experiment. Bayesian optimization allows joint tuning of more parameters with fewer experiments compared to a grid search or manual tuning. It also helps in finding better values. The Gaussian process (GP) is a Bayesian model that works well for Bayesian optimization. GP provides good uncertainty estimates of how an online metric varies with the parameters of interest. It is illustrated as follows: Source: Facebook research blog The work in the paper was motivated by several challenges in using Bayesian optimization for tuning online systems. The challenges are noise, constraints, and batch experimentation. In the paper, the authors describe a Bayesian approach for handling observation noise in which they include the posterior uncertainty induced by noise in EI’s expectation. In the paper, they describe a Bayesian approach for handling observation noise. A posterior uncertainty is induced by noise in EI’s expectation. Instead of computing the expectation of I(x) under the posterior of f(x), it is computed under the joint posterior of f(x) and f(x*). This expectation no longer has a closed form like El but can easily draw samples of values at past observations f(x_1), …, f(x_n) from the GP posterior. The conditional distribution f(x) | f(x_1), …, f(x_n) has closed form. The results The approach described in the paper is used to optimize various systems at Facebook. Two such optimizations are described in the paper. The first is to optimize six parameters from one of Facebook’s ranking systems. The second one was to optimize seven numeric compiler flags for the HipHop Virtual Machine (HHVM). The web servers powering Facebook use the HHVM to serve requests. The end goal of this optimization was to reduce CPU usage on the web servers, with a constraint of keeping the peak memory usage less. This following figure shows the CPU usage of each configuration tested. There is a 100 total, it also shows the probability that each point satisfied the memory constraint: Source: Facebook research blog The first 30 iterations were randomly generated configurations depicted as a green line. After this, the Bayesian optimization was used to identify parameter configurations to be evaluated. It was observed that Bayesian optimization was able to find better configurations that are more likely to satisfy the constraints. The findings are that Bayesian optimization is an effective and robust tool for optimizing via noisy experiments. For full details, visit the Facebook research blog.
