So, they are searching for whatever support they can get from experts. So for the sake of the benefit of the general masses, specifically those looking to learn AI and ML from scratch, we have come up with a sort of ‘Developers Guide to AI and ML’.
By using this path to learn machine learning, programmers, even those who have begun to code for the first time, can use this guide or path to achieve the goals they have been chasing for a long time without any clue.
Where should programmers start?
We have divided the learning path into two sections – AI and ML. We have further divided each section of the path into various stages, giving you individual knowledge of embarking on this journey in both sections. Remember, there is something for everybody, both AI and ML engineers. Every stage of the AI ML learning path contains various checkpoints, whether you want to learn and upgrade your AI or ML technological skills.
These checkpoints will help you climb each AI and ML Ladder rung, gradually increasing your technical knowledge of AI and ML theory and practical skills. In this manner, you will not get overwhelmed with all the information, and you will be able to build your foundation brick by brick, level by level, advancing by completely comprehending each level.
You will begin with learning to code in Python and will be taught all the mathematical concepts that come in handy in building customized ML models. Slowly, you will graduate to build micro and macro projects independently. But your story does not end here only. You will also be taught the best DevOps practices to apply to your ML projects for building them at an end-to-end pipeline.
AI and ML learning path: The roadmap
Given below is the AI ML learning path clearly and concisely. It will help you focus on areas where you should build up your machine learning and artificial intelligence skills.
Machine Learning Fundamentals
Python programming skills
Learning R or Python will enable you to build Machine Learning Models. Programming in these two languages will teach you big data handling and fine-tuning the model to manipulate the data. You have to learn how to use libraries, especially graphical ones. This will help you create ML algorithms without using heavy programming skills. Learning Python will benefit you as every company dealing with big data needs machine learning. Hence, the demand for Python is so great. Google, Facebook, Dropbox, YouTube, and Netflix use Python heavily, especially for building recommendation systems.
Python gives a lot of flexibility to Machine Learning engineers and helps in faster code development. You can also recompile the source code to view the developer’s changes. But which libraries of Python should you know how to use? We provide you with a list below:
- Matplotlib and Seaborn for spotting and visualizing data trends.
- Pandas help ML developers in data manipulation and analysis.
- Scikit-learn helps implement supervised and unsupervised algorithms for regression and classification.
- Keras and TensorFlow frameworks aid in creating, training, and deploying deep neural networks.
Python has a large community. So you can find a lot of documentation and teaching methods online. So you have excellent learning aids, whether a beginner or an expert.
R programming
R finds much usage in Machine Learning and Data science. With 18000+ packages and a community of 2 million users in the CRAN open-source repository, R is one of the widely-used programming languages in this domain. It aids in ML areas like visualization and computation of statistical data statistical computing. It is also handy for the analysis of this type of data. It’s also great for generating statistical graphics and is popularly used in Machine Learning techniques like regression and classification. It is an important part of a toolkit of a machine learning engineer.
Some important R programming language libraries are:
- Xgboost helps implement gradient boosting.
- Mlr aids in clustering, classification, and regression through s3 inheritance.
- PARTY supports recursive partitioning and generates decision trees.
- CARET helps in the integration of model training and prediction and aids in the selection of an ML algorithm.
Applied Mathematics/Statistics and Probability
It is not compulsory to possess in-depth knowledge of mathematics, and R and Python have libraries that include different frameworks for that. But you need to learn the following:
- Calculus helps in ML methods like gradient descent to identify optimum values. Partial derivatives help you to comprehend ML models.
- Probability and statistics help us understand random variables, conditional probability, and statistical independence. You can also calculate a dataset’s mean, median variance, and standard deviation. You will also be able to understand the differences between Gaussian and Binomial distribution and also distinguish between confidence intervals and p-values.
- Fundamental Linear Algebra will help you to build a base of matrices and vectors and how basic operations can be performed on them.
Data Cleaning
It is one of the important tasks of Machine Learning algorithm processing. Removing unwanted and faulty data will result in the building of an erroneous ML model. The performance of the cleaned-up dataset is a better-performing model. Performing cleansing on a huge dataset can be a cumbersome process, so you, as an ML engineer, should be able to accomplish this task.
You must be fully trained in the four main steps of cleaning data:
- Removal of unwanted data,
- Resolution of structural errors,
- Capable of handling unwanted outliers,
- Be able to handle missing data.
Once you have obtained the required machine learning skills and followed the ML learning path, you must perform some practical projects to get hands-on experience and enhance your expertise and knowledge in this domain.
