Foundation Building: Your First 2 Months
Mathematics Essentials
One does not have to be a mathematician to be successful in AI, but it is important to have the knowledge of basic mathematical concepts. Linear algebra is the foundation of AI algorithms, and it will teach you how data is represented and manipulated with the help of vectors and matrices. Neural networks and machine learning models seem to be filled with these ideas.
Probability and statistics make you know more about uncertainty and make predictions with data. You will also get to know about distributions, expectations, and Bayes theorem, the elements behind machine learning algorithms. Calculus (derivatives and gradients, in particular) is needed in computing the way models learn and optimize themselves.
Concentrate on intuitive learning as opposed to learning formulas. Visual resource and interactive tools can be used to visualize the impacts of mathematical operations on data. Good free sources of learning these fundamentals are Khan Academy, 3Blue1Brown on YouTube and MIT OpenCourseWare.
Programming Fundamentals
Python is the universal language of AI, and justifiably so. It is user friendly, has a vast library and it is a world wide application among professionals. Begin with simple syntax, data types such as lists and dictionaries, and control elements.
After being conversant with the basics of Python, explore critical libraries. NumPy is used to perform numerical calculations, Pandas is used to manipulate and analyze data, and Matplotlib is used to make beautiful Graphs to learn more about your data. These are the tools that accompany you in the AI work.
Jupyter Notebooks offer a learning and experimentation experience. They allow you to write code, watch the results instantly, and create note on your learning experience. Prepare development environment in advance and code everyday, however, even 30 minutes.
Data Literacy
The ability to comprehend information may be even more valuable than any algorithm you will study. Start with learning about the various types of data, including numeric and categorical, text and images. Get to know how to load datasets, check them, and find possible bugs.
Cleaning data is a process that takes a lot of time on the part of a data scientist. Exercise in management of missing values, elimination of duplication and management of outliers. Get to know the methods of exploratory data analysis so that you can reveal patterns and relationships in your data before using any machine learning.
The feature engineering converts raw data into useful inputs in models. This is the ability that creates a distinction between a good practitioner and a great practitioner. Practice developing new features, normalizing values, and encoding the categorical variables on actual data on platforms such as Kaggle.
Machine Learning Core: Months 3-5
Supervised Learning
Supervised learning is a method used to instruct machines on what to predict given labeled instances. Begin with the simplest algorithm, which is the linear regression, which determines relationships among variables. Even though it is simple, it is powerful and is the basis of more complex methods.
The logistic regression deals with classification issues where the predictor does not give the outcome, but the category. Switch to decision trees, where decisions are made by a sequence of questions, and random forests, where the results of several trees are combined to make improved decisions. The support vector machines determine the best boundaries between classes.
It is important to know values of measurement. Accuracy will tell you how many times your model works, but precision, recall and F1-score will give you more information about performance. Know how to apply each measure depending on your problem.
Unsupervised Learning
Data in unsupervised learning are identified as patterns without any labels. K-means divides similar points of data which are handy in customer groupings or image compressions. Hierarchical clustering constructs nested clusters which show data structure at various levels.
PCA is used to minimize the number of data dimensions but important information is maintained. The method assists in visualizing high dimensional data and accelerates the training of a model. Anomaly detection detects abnormalities, which is essential in fraud detection and quality control.
Apply these methods to actual data. Begin with the straightforward such as customer data clustering or image downsizing. The reason and time to apply one or the other method is learned through experience.
Essential Concepts
The train-test split is used so that your model does not merely memorize the data that it was trained on but learns patterns. The data that should be saved and never used by your model during the training process should always be put aside. Cross-validation is a better performance estimator because it is tested on multiple subsets of data.
Overfitting is a situation where the models have a good performance on the training data but not on the new data. The problem of underfitting occurs when models are insufficiently complex to model patterns of data. This trade-off can be explained by the bias-variance trade-off. Techniques such as regularization, such as the L1 and L2, are useful in avoiding overfitting, which is a negative attribute of a model.
The hyperparameter tuning is an optimization of the model settings that are not learned in the data. Systematic search Systematically investigate alternative configurations using grid search or random search. This process is made easy by scikit-learn which comes with inbuilt tools.
Deep Learning Foundations: Months 6-8
Neural Network Basics
Neural networks resemble the structure of the human brain, whereby the neurons relate to one another and process the information. Begin with the simplest neural units perceptrons which are the combination of inputs and the generation of outputs based on activation functions. Activation is like ReLU, sigmoid, and tanh, it adds non-linearity to networks, and so they can learn complicated patterns.
Forward propagation passes data in the network in order to come up with predictions. In backward propagation, the contribution of each connection to error is computed and weights are altered. Gradient descent optimization is an optimization technique that will update these weights to reduce the error of prediction over time.
Loss functions are used to determine the distance between predictions and real values. Mean squared error is used when regressing, whereas cross-entropy is used in classification. The ability to understand them well assists in debugging models and optimizing their performance.
Deep Learning Frameworks
Google has a strong deep learning ecosystem composed of TensorFlow and Keras. Keras is built with a user-friendly interface allowing users to create neural networks in a few lines and TensorFlow allows users with lower level control. Begin with a fast prototyping and experimentation with Keras.
Facebook has created PyTorch, which has become the favorite of researchers courtesy of its flexibility and ease of use. It implements dynamic computation graphs which are easier to debug. The two frameworks are well-documented and supported in the community.
The training is also accelerated significantly by means of parallel computation with the use of GPU acceleration. Get to know how to use the GPUs by using cloud services such as Google Colab which is free. This understanding is necessary when dealing with more significant models and datasets.
Common Architectures
Convolutional Neural Networks (CNNs) changed the computer vision as it learns the visual features automatically. They will rely on convolutional layers to identify features such as edges and textures, pooling layers to downsample, and fully connected layers to make a final prediction.
RNNs and Long short-term memory (LSTM) networks are used to process sequential data such as text and time series. They retain the history of the past inputs, and hence they are best applicable in language modeling and speech recognition. They, nevertheless, may have difficulties with long series.
Transfer learning is a technique that uses pre-trained models to tackle new problems using minimal data. You do not need to train models on large-scale data, but you learn them using models trained on large-scale datasets such as ImageNet. The method is time-saving, consumes fewer computational resources and gets good results.
Modern AI and Specialization: Months 9-12
Transformer Architecture
Among the components of AI, transformers altered everything with self-attention mechanism that gives more weight to various input components. Transformers, in contrast to RNNs, handle sequences in their entirety, which is significantly faster and more effective in language tasks.
BERT (Bidirectional Encoder Representations of Transformers) comprehends context in two directions of text. GPT (Generative Pre-trained Transformer) is a model that produces human-like text through predicting the following word. Most modern language models are powered using these architectures.
Fine-tuning is used to adapt already trained transformers to particular tasks with relatively small datasets. You change the weights of the model on your data and retain learned knowledge. Prompt engineering uses inputs to steer models without further training to desired outputs.
Large Language Models
ChatGPT, Claude, and GPT-4 are examples of Large Language Models that demonstrate impressive language generation and language comprehension abilities. They are trained with huge amounts of text and have the ability to write, code, and analyze a variety of tasks.
The API of the OpenAI, Hugging Face, and Anthropic works with LLM APIs, allowing you to build AI-powered applications without model training. Develop good prompts, manage responses and combine these functions into your projects.
Retrieval Augmentation Generations (RAG) systems integrate LLMs with external knowledge bases. They access corresponding information and apply them to come up with correct, grounded responses. This is to lessen hallucinations and update information.
Specialization Paths
Image and video data are used by the computer vision experts, who develop applications in the object detection, facial recognition, and self-driving cars. Pay attention to state-of-the-art CNN models, pre-processing of images, and data generation.
