“If 80 percent of our work is data preparation, then ensuring data quality is the important work of a machine learning team.” Andrew Ng The progress in machine learning progress owes a lot to teams downloading models and trying to do better on standard benchmark data sets. The bulk of the time is spent on improving the code, the model or the algorithms. “What I’m finding is that for a lot of problems, it’d be useful to shift our mindset toward not just improving the code but in a more systematic way of improving the data,” said Andrew Ng Last week, Andrew Ng drew the ML community’s attention towards MLOps, a field dealing with building and deploying machine learning models more systematically. Andrew Ng explained how machine learning development could accelerate if more emphasis is on being data-centric than model-centric. Traditional software is powered by code, whereas AI systems are built using both code (models + algorithms) and data. “When a system isn’t performing well, many teams instinctually try to improve the code. But for many practical applications, it’s more effective instead to focus on improving the data,” he said. Progress in machine learning, says Andrew Ng, has been driven by efforts to improve performance on benchmark datasets. The common practice amongst researchers is to hold the data fixed while trying to improve the code. But, when the dataset size is modest (<10,000 examples), Andrew Ng suggests ML teams will make faster progress, given the dataset is good. Improving code vs improving data quality (Source: Deeplearning.AI) It is commonly assumed that 80 percent of machine learning is data cleaning....
You must have seen how beautifully your day to day life is bound with lots of mobile apps.You start your day with various types of transport apps, continue it by entertaining yourself with various social media, eCommerce apps and end it with various gaming and informative apps. Whatever the activity you perform is based on various kinds of mobile apps whether it is related to personal life or professional life. It means apps are playing a crucial role in your day to day life. Do you know that developers have to face a lot of challenges so that they could make applications that work well on multiple platforms? This issue could be resolved with different types of cross-platform mobile app development tools. This piece of article is going to make you aware of the top cross-platform mobile app development tools with the help of which you can develop cutting edge cross-platform mobile apps. Let’s have a deep look: Xamarin Xamarin is known as the best choice for native applications. This is helpful for these types of functions such as large amounts of local data, offline mode, and image recognition required to be implemented. According to Datanyze, The market share of Xamarin to date in 2020 is 31% in the US. This tool runs on the .Net common language as it is built on the C# programming language. This tool is used to build apps for multiple platforms such as iOS, Windows, and Android. With the help of the Xamarin tool, mobile application developers can create scalable and robust applications by taking the help of its QA and testing features. This tool is really amazing...
The latest on ransomware gangs and their strategies. Welcome to Cyber Security Today. It’s Monday May 17th. I’m Howard Solomon, contributing reporter on cybersecurity for ITWorldCanada.com. Is the Darkside ransomware gang dead or temporarily going quiet? Has ransomware suddenly got a bad name among crooks? This is what many cybersecurity experts are wondering after Darkside said it had lost access to the public part of its blog, payment server and content delivery server. Not only that, Darkside is releasing its decryption keys so anyone hit by its ransomware could get their scrambled data back for free. In addition cryptocurrency funds were also taken by someone from the gang’s payment sever, which is where victims made ransomware payments. This came after U.S. President Joe Biden urged Moscow to take action against the reportedly Russia-based group for its attack on the Colonial Pipeline in the U.S., and Biden promised the U.S. would disrupt the gang. On top of this, one Russian cybercrime forum suddenly banned all discussion threads about ransomware, saying the topic is now toxic. And the REvil gang has been quoted as saying it will keep a closer eye on affiliate crooks who want to use its ransomware platform to make sure they stay away from attacking what it calls the social sector and governments. Are ransomware gangs disbanding, afraid of aggressive law enforcement? Or is this smoke and mirrors? First of all, note that REvil is merely saying it’s going to be more selective in targets. Apparently it thinks that will cool things off. As for Darkside, perhaps some of its money is gone but the gang still...
If you’re a seasoned web developer, you would have probably heard of AngularJS, an advanced JavaScript framework built to enhance HTML for web applications. Developed by extremely talented Google engineers Adam Abrons and Miško Heverym in 2009, AngularJS has gained tremendous popularity due to outstanding features it ships with. This blog post is written to give you a clear picture of benefits that you can take by using AngularJS in your projects. Firstly, I’ll tell you what actually AngularJS is, and then give you some solid reasons that will definitely compel you to think “why it’s crucial to adopt AngularJS today”. Let’s begin! What is AngularJS? AngularJS, often referred to as Angular, is an open-source JavaScript framework, designed to simplify both front-end development and testing tasks for web developers. Written in pure JavaScript, Angular is most suitable for developing single-page web applications that only require client-side programming languages such as HTML, CSS and JavaScript. It’s a fully extensible, next generation MVC (Model–view–controller) framework that doesn’t only run without all possible library dependencies, but also works perfectly with other libraries. AngularJS – the self-proclaimed “superheroic JavaScript MVW (Model-View-Whatever) framework” – allows you to use HTML as template language and enables you extend HTML vocabulary, so you could express each and every component of your application in a clear and concise manner. By helping developers write and test JavaScript code better, Angular makes the browser flawlessly work with any server technology. In a nutshell, this fabulous framework is built to bring MVC capability to modern web applications. Why to Choose AngularJS for Your Next Web App? Below are some good reasons...
This article is meant to serve as a practical guide to becoming a professional web developer. I’ve spent over 20 years writing code for the web. I work with and help developers daily. In this article, I will tell you what you should learn, when you should learn it, and where you can learn it from (usually for free ). I’ll then give you advice on how to get real world experience and, most importantly, how to get paid for writing code. Author’s Note: Due to popular demand, this article is now available as an expanded eBook that includes a special appendix that puts all the links from this article in one easy to follow list. You can get the eBook version here. I get no direct compensation for mentioning any of the sites listed here. I just want to provide you with the best resources possible to help you get where you’re going.Two things to keep in mind… 1. It’s okay to skip ahead. This guide will help you no matter where you are on your journey toward becoming a professional developer. After reading this introduction, just scroll to the heading that best describes your situation and begin reading from there.
