Questions & Answers

Q: What is machine learning?

Machine learning is the process of using data to build models that can make predictions or find patterns. It involves using algorithms and mathematical techniques to analyze data and uncover insights.

Q: What is the simplest form of machine learning?

The simplest form of machine learning is curve fitting or regression. In this approach, a model is built to fit data points on a graph, such as fitting a straight line between two curves representing cholesterol levels and the probability of heart disease. This allows the model to make predictions for new data points.

Q: What has been the basis of the computer revolution?

The basis of the computer revolution is the combination of the problem-solving power of mathematics and logic with the speed and accuracy of machines. This combination allows computers to carry out complex operations and process large amounts of data, enabling advances in various fields, including data science and machine learning.

Q: What has changed in machine learning?

There has been a sea change in machine learning, where the focus has shifted from human-specified features to models that can learn the features themselves. Instead of humans having to determine the relevant features and establish causal connections, modern machine learning algorithms can automatically identify and learn features from the data.

Q: How has this change impacted fields like genomics?

This change has revolutionized fields like genomics. Previously, researchers would have to study specific genes or sequences in detail to understand their features. Now, machine learning can infer predictions and find patterns in DNA sequences without having prior knowledge of the underlying biology. This has led to advancements in areas like cancer detection and diagnosis.

Q: What is deep learning?

Deep learning is a type of machine learning that involves stacking multiple layers of models on top of each other. In this deep hierarchy, the lowest level models capture basic features, such as DNA base symbols, while higher-level models aggregate patterns and motifs from these basic features. Deep learning has become powerful due to advancements in computational power and the availability of large datasets.

Q: What are the advantages of deep learning?

The two main advantages of deep learning are increased compute power and more abundant data. With enough compute power, deep learning models can be trained to learn complex features and patterns. Similarly, with large amounts of data, these models can be trained in a rich and accurate way, resulting in high prediction accuracy.

Q: How does old-school machine learning compare to newer techniques?

In old-school machine learning, humans would specify the features to be used, and the models would provide quantitative predictions based on these features. However, with newer techniques, computers can figure out the salient details and learn the features themselves. This has led to more accurate predictions and a shift towards artificial intelligence, where computers can identify key elements and discover new insights.

Q: How do computers learn features in modern machine learning?

In modern machine learning, computers learn features by analyzing large datasets. By training models on these datasets, computers can identify patterns and correlations that humans may have missed. This allows them to make accurate predictions and provide insights without prior knowledge of the underlying features.

Q: How is modern machine learning pushing towards artificial intelligence?

Modern machine learning, with its ability to learn features and make accurate predictions, is pushing towards artificial intelligence. Computers can now discover key salient elements and identify features that humans may have never come up with. This opens up new possibilities for understanding biology and making advancements in various fields.
