In 2019, Venturebeat reported that almost 87% of data science projects do not get into production. Redapt, an end-to-end technology solution provider, also reported a similar number of 90% ML models not making it to production. However, there has been an improvement. In 2020, enterprises realized the need for AI in their business. Due to COVID-19, most companies have scaled up their AI adoption and increased their AI investment.

The main function of MLOps is to automate the more repeatable steps in the ML workflows of data scientists and ML engineers, from model development and training to model deployment and operation (model serving). Automating these steps creates agility for businesses and better experiences for users and end customers, increasing the speed, power, and reliability of ML. These automated processes can also mitigate risk and free developers from rote tasks, allowing them to spend more time on innovation. This all contributes to the bottom line: a 2021 global study by McKinsey found that companies that successfully scale AI can add as much as 20 percent to their earnings before interest and taxes (EBIT). "It's not uncommon for companies with sophisticated ML capabilities to incubate different ML tools in individual pockets of the business," says Vincent David, senior director for machine learning at Capital One.

AI can power phenomenal revenue growth – until it doesn't. That lesson is being learned the hard way at a growing number of companies where issues with AI systems are not caught and remedied before materially impacting revenue. The latest example is Unity Software, a platform for creating and operating interactive and real-time 3D (RT3D) content. On its most recent earnings call, Unity revealed that it missed top line expectations and lowered its revenue guidance for the rest of the year due in part to a "self-inflicted wound" in AI. Specifically, the company's CEO and Executive Chairman John Riccitiello cited several issues related to machine learning (ML) models that caused an estimated impact to the business of approximately $110 million in 2022: When AI fails on the public stage like this, the temptation to pile onto whatever company is on the chopping block is sometimes irresistible (see: Zillow).

Although they certainly work together amicably and enjoy some overlap concerning expertise and experience, the two roles serve quite different purposes. Essentially, we are differentiating between Scientists who seek to understand the science behind their work, and Engineers who seek to build something that can be accessed by others. Both roles are extremely important, and at some companies, are interchangeable -- for example, Data Scientists at certain organizations may carry out the work of a Machine Learning engineer and vice versa. To make the distinction clear, I'll split the differences into 3 categories; 1) Responsibilities 2) Expertise 3) Salary Expectations. Data Scientists follow the Data Science Process, which may also be referred to as Blitzstein & Pfister workflow.

I started my career in 2010 after a master's in computer science. During my studies, I got hooked on software engineering. It can be really fascinating! You get to build stuff out of nothing. You start from a virtual blank sheet, and you can end up with an empire.

Transformer models are the de-facto standard in modern NLP. They have proven themselves as the most expressive, powerful models for language by a large margin, beating all major language-based benchmarks time and time again. In this course, we learn all you need to know to get started with building cutting-edge performance NLP applications using transformer models like Google AI's BERT, or Facebook AI's DPR. Throughout each of these use-cases we work through a variety of examples to ensure that what, how, and why transformers are so important. Alongside these sections we also work through two full-size NLP projects, one for sentiment analysis of financial Reddit data, and another covering a fully-fledged open domain question-answering application.
