Hulu is a U.S.-listed online video company in 2007, offering subscription-based video services with a business model similar to the domestic love-odd art and Youku. Hulu released the latest OTT live TV app--hulu in May this year, with the aim of replacing the traditional cable TV service, and the recent emergence of live broadcast applications such as YY, Ying, e

This is the second machine study this week, is also the 17th article of the Hulu Face Test series ~ All the content before can be found in the menu bar "machine learning", may you warm, know new.Today's content is"Classical variants of the random gradient descent algorithm"Scenario DescriptionReferring to the optimization method in deep learning, people would think of stochastic Gradient descent (SGD), but SGD is not the ideal balm, but sometimes it b

The answer to this issue, combined with a specific Hulu business case, can be said to be interesting and understood. Come on, learn!Today's content is"Classification, sequencing, evaluation of regression models"Scenario DescriptionIn the model evaluation process, classification problems, sequencing problems, regression problems often need to use different evaluation indicators for evaluation. However, in many evaluation indicators, most of the indicat

This article is the main work I have done in Hulu this year, combined with the current popular two open source solutions Docker and yarn, provide a flexible programming model, currently supporting the DAG programming model, will support the long service programming model. Based on Voidbox, developers can easily write a distributed framework, Docker as a running execution engine, yarn as a management system for cluster resources. This article i

Nocedal. "On the limited memory BFGS method for large scale optimization." Mathematical Programming 45.1 (1989): 503-528.Next Topic Preview"The classical variant of the random gradient descent algorithm "Scenario DescriptionReferring to the optimization method in deep learning, people would think of stochastic Gradient descent (SGD), but SGD is not the ideal balm, but sometimes it becomes a pit. When you design a deep neural network, if you only know to train with SGD, and in many cases you get

Question meaning: In n countries, each country has a fear value, and each country belongs to one continent. Aliens Attack k times. Each time they attack three countries in different continents, they will ask you the maximum number of times you can

There are n countries, each of which belongs to one continent. now someone is going to attack some countries. Each attack will come from three different continents. We can choose to protect one country, the fear value of the protected country is-2,

I took part in Hulu's test on Friday. I had a lot of questions in 70 minutes and I was not prepared enough. It took 40 minutes for the first 10 multiple choice questions, the last five blank questions had to be left blank. In this case, the time is

computing engine in this field, a true streaming system that reads a single piece of data from a data source and processes it individually. Faster response time (less than one second) compared to spark Streaming,storm, which is better suited for low latency scenarios such as credit card fraud systems, advertising systems, etc. However, the advantage of comparing Storm,spark streaming is that the throughput is large, the response time is also acceptable (in seconds) and compatible with other too

internal components. With the new basic service architecture, the group replication plug-in can now notify other components on the server about Member-related events. For example, notifying members of a group of roles to change the role of the group is lost in arbitration. Other components can provide feedback on this information, and users can develop their own components to record and detect these events. Delete the redundant information on the node from the internal structure of

underlying service architecture, the group replication plug-in can now notify other components in the server about the events associated with the member. For example, the role of the notification group member changes quorum loss, and so on. Other components can provide feedback on this information, and users can develop their own components to record and detect these events. Remove redundant information on the node from the internal structure of the xco
