- Mathematical and Statistical Fundamentals:
- A strong grasp of Linear Algebra (vectors, matrices, and their operations) is essential for understanding how most algorithms work.
- Solid knowledge of Probability and Statistics is required for data analysis, model evaluation, and handling uncertainty.
- Understand Calculus (especially derivatives and gradients) as it underpins model optimization techniques like gradient descent.
- Core Data Science:
- Learn Data Cleaning and Preparation, as high-quality data is the lifeblood of AI.
- Master Exploratory Data Analysis (EDA) and data visualization to extract meaningful insights.
Stage 2: Master Machine Learning & Deep Learning
This stage introduces the fundamental AI methodologies.
- Machine Learning (ML) Mastery:
- Understand the three main learning paradigms: Supervised, Unsupervised, and Reinforcement Learning.
- Learn to implement and evaluate classical ML algorithms, such as Linear Regression, Decision Trees, Random Forests, and Support Vector Machines.
- Deep Learning & Neural Networks:
- Dive into Deep Learning, the advanced subset of ML that uses multi-layered neural networks.
- Gain hands-on experience with frameworks like PyTorch or TensorFlow/Keras.
- Study different neural network architectures like Convolutional Neural Networks (CNNs) for image tasks and Recurrent Neural Networks (RNNs) / Transformers for sequence data.
Stage 3: Specialization and Cutting-Edge Skills (2025 Focus)
The current AI boom is characterized by specific technologies that demand specialized skills. Choose a specialization and go deep.
