I believe that these lessons are so important because they are instrumental to having a successful data science career. After reading this, you'll realize that there's much more to being a good data scientist than building complex models. With that said, here are my 3 most important lessons I've learned in my data science career! One thing that I noticed is that almost all data science courses and boot camps emphasize and elaborate on the modeling phase of the lifecycle of a project, while in reality, that only makes up a small component of the entire process. If it takes you a month to build a preliminary machine learning model at work, you can expect to spend a month understanding the business problem beforehand and documenting and socializing the project afterward.

My statistics course is ideal for those studying on their own, or if you are in a statistics class and struggling with your assigned textbook or lecture material. I know stats courses can be boring, so I try to make it as exciting as possible. The examples have a psychology bend, but this course is absolutely relevant for business students, especially those in data analysis that have to get a better understanding of statistical tests and the fundamental concepts. So welcome to you whether you are in business or psychology. I provide examples within the lessons, so this should cut down your study time. Furthermore, I make sure that students understand the links between the different lessons.

I recently started to follow an exciting and mind-bending philosophy online course at MIT called Minds and Machines. The course is a thorough, rigorous 12 Weeks Learning Path introduction to contemporary philosophy of mind, exploring consciousness, reality, artificial intelligence (AI), and more. It is definitively one of the most in-depth philosophy courses available online that I ever frequented. The first effect of starting study philosophy at Massachusetts Institute of Technology is that I'm asking more challenging questions… the second effect is that I'm writing more about those questions. I'm in this moment, exploring the relationship between the mind and the body, the capacity of computers to think, the way we perceive reality, and the perspective of the existence of a science of consciousness. As a first result, I've started to pay particular attention to one specific question that definitively has a lot to relate to my daily work as an AI expert: what is intelligence?

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.

Driven by the need to capture users' evolving interests and optimize their long-term experiences, more and more recommender systems have started to model recommendation as a Markov decision process and employ reinforcement learning to address the problem. Shouldn't research on the fairness of recommender systems follow the same trend from static evaluation and one-shot intervention to dynamic monitoring and non-stop control? In this paper, we portray the recent developments in recommender systems first and then discuss how fairness could be baked into the reinforcement learning techniques for recommendation. Moreover, we argue that in order to make further progress in recommendation fairness, we may want to consider multi-agent (game-theoretic) optimization, multi-objective (Pareto) optimization, and simulation-based optimization, in the general framework of stochastic games.

In any data science project life cycle, cleaning and preprocessing data is the most important performance aspect. Say if you are dealing with unstructured text data, which is complex among all the data, and you carried the same for modeling two things will happen. Either you come up with a big error, or your model will not perform as you expected. You might have wondered how the modern voice assistance system such as Google Assistance, Alexa, Siri can understand, process and respond to human language, so here comes the heavy lifter. Natural language processing, NLP, is a technique that comes from the semantic analysis of data with the help of computer science and artificial intelligence.

The field of data science is growing with increasing demand. Data science is not limited to only consumer goods or tech or healthcare. There is a high demand to optimize business processes using data science from banking, transport to manufacturing. Organizations are now hiring data science professionals to deal with complex data.

However, keeping in mind that there is no "right way" to study or pursue a career in data science – a self-study plan is not an alien concept. So, let's dive deep for a detailed comparison between the two on various aspects. The field of data science looks for skills and problem-solving attitudes. Getting degrees is an accomplishment, but degrees alone offer no guarantee of landing a job. Pick up a programming language (Python or R), learn how to code, and practise fundamental concepts such as calculus, statistics, probability, regression analytics, etc. Once the foundation is well-laid, go for advanced specialisation in neural networks, machine learning, and deep learning.

There is nothing magic about magic. The magician merely understands something simple which doesn't appear to be simple or natural to the untrained audience. Once you learn how to hold a card while making your hand look empty, you only need practice before you, too, can "do magic." Note: Please raise an issue for any suggestions, corrections, and feedback. The goal of the series is to understand the basics of MLOps like model building, monitoring, configurations, testing, packaging, deployment, cicd, etc.

Data Science is a blend of various tools, algorithms, and machine learning principles with the goal to discover hidden patterns from the raw data. But how is this different from what statisticians have been doing for years? The answer lies in the difference between explaining and predicting. A Data Analyst usually explains what is going on by processing history of the data. On the other hand, Data Scientist not only does the exploratory analysis to discover insights from it, but also uses various advanced machine learning algorithms to identify the occurrence of a particular event in the future.
