This sub-module will introduce you to the fundamental concepts and principles of machine learning, which are essential for integrating AI into biotech research.

#### Supervised vs Unsupervised Learning

In supervised learning, the computer is trained on labeled data, where each example is accompanied by a target or response variable. The goal is to learn a mapping between input variables (features) and output variables (target). For instance, in image classification, the algorithm learns to identify objects based on visual features and corresponding labels.

Example: A medical researcher uses supervised learning to train an AI model to classify cancerous cells from normal cells based on microscopic images. The labeled dataset consists of images with corresponding diagnoses.

In unsupervised learning, the computer is trained on unlabeled data, and the goal is to discover hidden patterns or relationships within the data. This type of learning is useful for exploratory data analysis and clustering similar data points together.

Example: A bioinformatician uses unsupervised learning to identify gene clusters in a set of DNA sequences without prior knowledge of the cluster's meaning. The algorithm groups similar sequences based on their sequence features, which can lead to new insights into genetic regulation or evolutionary relationships.

Types of Machine Learning Models

Machine learning models are categorized into three primary types:

• Linear Regression: A linear model that predicts a continuous output variable based on one or more input variables.
• Decision Trees: A tree-like model that makes decisions based on feature values and splits the data into subsets.
• Neural Networks: A complex, non-linear model inspired by the human brain's neural networks. Neural networks consist of interconnected nodes (neurons) with weighted connections.

Example: A biologist uses linear regression to predict the expression level of a gene based on environmental factors like temperature and light exposure.

Overfitting and Regularization

As machine learning models become more complex, they can easily overfit the training data, resulting in poor performance on unseen data. Overfitting occurs when a model becomes too specialized to the training data and fails to generalize well to new instances.

Regularization techniques:

• L1 and L2 regularization: These methods add penalties to the loss function during training to prevent large weights or coefficients.
• Dropout: A technique that randomly drops neurons or features during training to avoid over-reliance on specific inputs.

Evaluation Metrics for Machine Learning Models

When evaluating machine learning models, it's essential to use relevant metrics that align with the problem domain. Common evaluation metrics include:

• Accuracy: The proportion of correctly classified instances.
• Precision: The proportion of true positives among all predicted positive instances.
• Recall: The proportion of true positives among all actual positive instances.
• F1-score: The harmonic mean of precision and recall.

Example: A biotech researcher evaluates a classification model for predicting protein function based on sequence features. They use accuracy, precision, and recall to assess the model's performance and identify areas for improvement.
