Key Areas of Focus
The study plan highlights critical areas in machine learning:
LeetCode and SQL
Rather than relying solely on LeetCode questions, the guide suggests various approaches, acknowledging that many paths lead to becoming a machine learning engineer. Additionally, it emphasizes SQL skills, including joins and window functions, with recommended practice on platforms like HackerRank.
Programming
The guide covers essential programming concepts such as Java garbage collection, Python's pass-by-object-reference, and concurrency in Python.
Statistics and Probability
This section includes resources for mastering statistical concepts, vital for interpreting and analyzing data effectively in machine learning roles.
Big Data
While big data knowledge isn't necessary for interviews with all companies, the guide offers resources for understanding frameworks like Spark and Cassandra, and practical challenges like MapReduce.
Machine Learning Fundamentals
The project includes foundational topics such as:
- Understanding and comparing algorithms like Random Forest and Gradient Boosting.
- Implementing logistic regression from scratch.
- Theoretical insights into supervised and unsupervised learning, feature scaling, and model evaluation.
Deep Learning
The deep learning section covers:
- Activation functions and neural network architectures like CNNs and RNNs.
- Optimization techniques and practical applications of deep learning in production.
Testimonials
