The Machine Learning University Course Overview
The Machine Learning University is a comprehensive course that covers various aspects of machine learning, including supervised and unsupervised learning, neural networks, deep learning, computer vision, and text processing. The course consists of nine modules, each focusing on a specific topic.
Learning Approaches in Machine Learning
------------------------------------
The course begins by covering the learning approaches comprising supervised and unsupervised learning. It is essential to understand that class imbalance is a critical issue in machine learning, particularly when the number of samples belonging to different classes are not equal. This can lead to inherent bias in the model, resulting in poor performance. To tackle this problem, there are ways to address it, such as oversampling and undersampling.
Oversampling involves increasing the number of samples in the minority class, while undersampling reduces the number of samples in the majority class. For example, if a dataset has 100 samples in class A and 200 samples in class B, oversampling can increase the number of samples in class A to 200, making both classes have an equal number of samples.
Machine Learning Applications
---------------------------
The course then moves on to machine learning applications, covering various topics such as supervised and unsupervised learning. It is essential to understand that machine learning models need to be trained and evaluated to ensure they are performing well.
Computer Vision Applications
-------------------------
The next module focuses on computer vision applications, including image representation, neural networks, and components of neural networks. The course also covers the development of computer vision models, including underfitting and overfitting, as well as model evaluation techniques.
Convolution Filters and Neural Networks
--------------------------------------
A key component of neural networks is convolution filters, which are used to extract features from images. The course covers the basics of convolution filters, including padding, stride, and pooling.
Deep Learning
--------------
The next module focuses on deep learning, covering various topics such as recurrent neural networks, gated recurrent units, long short-term memory networks, single-headed attention, and multi-headed attention.
Recurrent Neural Networks and Long Short-Term Memory Networks
-----------------------------------------------------------
Recurrent neural networks are designed to handle sequential data, such as time series or text. The course covers the basics of recurrent neural networks and long short-term memory networks, which are a type of recurrent neural network that can learn long-term dependencies in data.
Transformers and Attention Mechanisms
--------------------------------------
The course also covers transformer-based models, including single-headed attention and multi-headed attention. These mechanisms enable the model to attend to different parts of the input sequence simultaneously.
Underfitting and Overfitting
---------------------------
One of the challenges in machine learning is underfitting, where the model is too simple to capture the underlying patterns in the data. The course covers techniques for avoiding underfitting, such as regularization and hyperparameter tuning.
Regularization and Hyperparameter Tuning
-----------------------------------------
Regularization techniques can help prevent overfitting by adding a penalty term to the loss function. The course covers various regularization techniques, including L1 and L2 regularization.
Hyperparameter Tuning is essential to find the optimal set of parameters for a machine learning model. It involves adjusting the hyperparameters to achieve the best performance on a validation set while avoiding overfitting.
Text Processing and Preprocessing
---------------------------------
The final module focuses on text processing and preprocessing, covering various techniques such as tokenization, stemming, and lemmatization.
Text Vectorization
------------------
Text vectorization is a critical step in text processing, where the input text is converted into a numerical representation that can be fed into a machine learning model. The course covers various techniques for text vectorization, including bag-of-words and word embeddings.
