Artificial Intelligence and Machine Learning are the buzzwords of the decade.
With endless possibilities and exciting advancements, it's no wonder that more people than ever are interested in breaking into these fields. But with so much competition, how do you get into AI and Machine Learning?
Whether you're a seasoned professional looking to pivot or a newcomer just starting out, these tips will set you on the path towards success in this rapidly growing industry.
Below are seven steps in order we recommend newcomers take to develop an understanding of Machine Learning, starting with the basics, and then moving toward applying your skills and understanding which Machine Learning roles fit you best - culminating with finding a new job in this field.
1. First, develop an understanding of Machine Learning
In order to get into the field of AI and machine learning, it's important to develop a strong understanding of the basics of these technologies.
There are many different types of machine learning models, such as linear regression, decision trees, and neural networks. The choice of model depends on the problem you are trying to solve and the type of data you have.
To build a machine learning model, the data is split into training and validation sets. The model is trained on the training set and then evaluated on the validation set to see how well it generalizes to new data. There are several metrics used to evaluate the performance of a machine learning model, such as accuracy, precision, recall, and F1 score. The choice of metric depends on the problem you are trying to solve.
Finally, most machine learning models have hyperparameters that need to be tuned to improve performance. This involves trying different values for the hyperparameters and evaluating the model's performance on the validation set.
2. Make sure you develop an understanding of Deep Learning, too
Deep learning is a subset of Machine Learning, but it's important to have some general knowledge here too.
Deep Learning is based on artificial neural networks, which consist of layers of interconnected nodes. The key components of deep learning include input layers, hidden layers, and output layers, as well as activation functions, loss functions, and optimization algorithms.
Some of our additional recommendations for teaching yourself Deep Learning also include:
Knowing the deep learning architectures: There are several key deep learning architectures to be familiar with, including feedforward neural networks, convolutional neural networks (CNNs), recurrent neural networks (RNNs), and generative adversarial networks (GANs). Each architecture has its own strengths and weaknesses, and can be applied to different types of problems.
Experimenting with tools and frameworks for Deep Learning: There are several popular tools and frameworks for building and training deep learning models, including TensorFlow, PyTorch, and Keras. These tools provide a high-level interface for building and training neural networks, as well as support for distributed training and other advanced features.
Understanding best practices: Deep learning is a complex field, and there are many best practices to keep in mind when building and training models. This includes techniques for data preparation and preprocessing, regularization and dropout to prevent overfitting, and hyperparameter tuning to optimize model performance.
3. Gain an understanding of at least one programming language you can use in Machine Learning
To work in Machine learning, it's important to have knowledge of at least one programming language that can handle numerical computation and has a strong machine learning or deep learning library. Some of the most popular programming languages used in Machine Learning include:
Python: Python is one of the most popular programming languages for deep learning due to its simplicity and versatility. It has a wide range of libraries for machine learning and deep learning, including TensorFlow, Keras, PyTorch, and scikit-learn.
R: R is a popular language for statistical computing and data analysis. It has several packages for deep learning, such as mxnet and KerasR.
MATLAB: MATLAB is a powerful language for numerical computation, and it has several deep learning toolboxes, such as the Deep Learning Toolbox.
Julia: Julia is a relatively new programming language that has been designed for high-performance numerical computing. It has a growing community of developers building deep learning packages, such as Flux.jl.
C++ and CUDA: C++ is a general-purpose programming language used for high-performance computing, and CUDA is a parallel computing platform and programming model developed by NVIDIA for GPU acceleration. Together, these two languages are used to build high-performance deep learning models.
Python is by far the most popular language for deep learning, and it is recommended that beginners start with Python and one of its deep learning libraries like TensorFlow, PyTorch, or Keras.
Finally, a word of advice - have fun here! Don't feel like you need to limit yourself to one programming language, or becoming an expert in one of the languages right away. Experiment and try out multiple technologies, having fun along the process.
4. Decide how you want to apply your knowledge of Machine Learning
It's important to be familiar with the wide range of applications of deep learning. By understanding the potential of deep learning, you can identify opportunities to apply it in your own work or research, and decide which career path you want to take within the field. Some of the most common applications of Machine Learning include:
