None of the candidates could give a satisfactory answer. May be, they thought becoming a data scientist has nothing to do with following them. Think back, when you were a kid and played sports, didn't you admire any sports player and aimed to be like him / her, when you grow up? The path to becoming a data scientist is exhausting, just like a marathon. To ensure you don't fall out, it is important that you keep seeking motivation from what others are doing.


The Fundamental Differences Between ML Model Development and Traditional Enterprise Software Development - DZone AI

#artificialintelligence

Academic literature on machine learning modeling does not explicitly address how enterprises across industries can utilize ML algorithms. And many companies, even after investing in foundational ML tools, still often get puzzled when defining business use cases for their AI apps, customizing general purpose machine learning models for domain-specific tasks, converting business requirements into data requirements, etc. In this post, we'll talk about key differences between traditional enterprise software development and ML model building and offer some ML lifecycle management tips (chiefly concerning data preparation and feature engineering) for those seeking to harness AI. In traditional software development we write out explicit instructions for a computer to follow and, therefore, the applications we end up with are deterministic. In machine learning, which is probabilistic in nature, we rely on data to write our if-then statements.


Demystifying Mathematical Concepts for Deep Learning

#artificialintelligence

Data science is an interdisciplinary field that uses mathematics and advanced statistics to make predictions. All data science algorithms directly or indirectly use mathematical concepts. Solid understanding of math will help you develop innovative data science solutions such as a recommender system. If you are good at mathematics, it will make your transition into data science easier. As a data scientist, you have to utilize the fundamental concepts of mathematics to solve problems.


10 Machine Learning Startups Transforming Their Industries - Disruption Hub

#artificialintelligence

Artificial intelligence is one of the technologies with the most transformative potential in business. According to research by McKinsey, 70 per cent of companies are likely to have adopted at least one form of AI by 2030. This will contribute to an additional $13tr of global economic activity. Machine learning – a subset of artificial intelligence – enables machines to get better at executing tasks without human intervention, by finding patterns in data, and learning from their experience. It's no surprise, therefore, that there has been an explosion in the number of machine learning companies worldwide.


Automated Machine Learning (AML) Comes of Age - Almost

#artificialintelligence

Summary: Forrester has just released its "New Wave: Automation-Focused Machine Learning Solutions, Q2 2019" report on leading stand-alone automated machine learning platforms. This is our first good side-by-side comparison. You might also want to consider some who were not included. You know you've come of age when the major review publications like Gartner and Forrester publish a study on your segment. Just released is "The Forrester New Wave: Automation-Focused Machine Learning Solutions, Q2 2019".


If you're a developer transitioning into data science, here are your best resources

#artificialintelligence

It seems like everyone wants to be a data scientist these days -- from PhD students to data analysts to your old college roommate who keeps Linkedin messaging you to'grab coffee'. Perhaps you've had the same inkling that you should at least explore some data science positions and see what the hype is about. Maybe you've seen articles like Vicki Boykis' Data Science is different now that states: Concepts like unit testing and continuous integration rapidly found its way into the jargon and the toolset commonly used by data scientist and numerical scientist working on ML engineering. What's not clear is how you can leverage your experience as a software engineer into a data science position. Are there best practices or tools that are different for data scientists?


Analyzing & Preventing Unconscious Bias in Machine Learning

#artificialintelligence

I just briefly wanted to say a little bit about my background. I studied Math and Computer Science in college and then did a Ph.D. in Math. I worked as a quant in Energy Trading and that's where I first started working with data. I was an early data scientist and backend developer at Uber. I taught full stack software development at Hackbright. I really love teaching and I think I'll always return to teaching in some form. And then two years ago, together with Jeremy Howard, I started fast.ai with the goal of making deep learning more accessible and easier to use. I just have one slide about fast.ai. We have this, as William mentioned, a totally free course, "Practical Deep Learning for Coders." The only prerequisite is one year of coding experience. It's distinctive in that there are no advanced math prerequisites, yet it takes you to the state-of-the-art. We've had a lot of success. We've had students get jobs at Google Brain, have their work featured on HBO and in Forbes, launch new companies, get new jobs. I wanted to let you know that this is out here, and this was a partnership between fast.ai, which is a non-profit research lab, and the University of San Francisco's Data Institute.


Infosys - AI & Big Data Expo Europe 2019

#artificialintelligence

The AI & Big Data Expo Europe, the leading Artificial Intelligence and big data conference and exhibition event, will take place on June 19 – 20, 2019, at the RAI, Amsterdam. It is a showcase of next generation technologies and strategies from the world of Artificial Intelligence and big data -- an opportunity to explore and discover the practical and successful implementation of AI and big data in driving forward your business in 2019 and beyond. The AI & Big Data Expo will bring together 2,000 visitors over the two days, including IT decision makers, developers and designers, heads of innovation, chief data officers, chief data scientists, brand managers, data analysts, start-ups and innovators, tech providers, C-level executives, and venture capitalists. This track covers the full spectrum of AI technologies -- how they are being developed and the real life scenarios where they are being utilized. Expect to hear about chatbots, visual recognition technologies, robotics, and machine learning.


R vs. Python: Which is a better programming language for data science?

#artificialintelligence

Python vs. R is a common debate among data scientists, as both languages are useful for data work and among the most frequently mentioned skills in job postings for data science positions. Each language offers different advantages and disadvantages for data science work, and should be chosen depending on the work you are doing. To help data scientists select the right language, Norm Matloff, a professor of computer science at the University of California Davis wrote a Github post aiming to shed some light on the debate. While this is subjective, Python greatly reduces the use of parentheses and braces when coding, making it more sleek, Matloff wrote in the post. While data scientists working with Python must learn a lot of material to get started, including NumPy, Pandas and matplotlib, matrix types and basic graphics are already built into base R, Matloff wrote.


Advanced Machine Learning with Basic Excel

#artificialintelligence

In this article, I present a few modern techniques that have been used in various business contexts, comparing performance with traditional methods. The advanced techniques in question are math-free, innovative, efficiently process large amounts of unstructured data, and are robust and scalable. Implementations in Python, R, Julia and Perl are provided, but here we focus on an Excel version that does not even require any Excel macros, coding, plug-ins, or anything other than the most basic version of Excel. It is actually easily implemented in standard, basic SQL too, and we invite readers to work on an SQL version. In short, we offer here an Excel template for machine learning and statistical computing, and it is quite powerful for an Excel spreadsheet.
