Question

What is a Machine Learning model?

Show answer

Answer

A Machine Learning model is a mathematical model trained on data to make predictions or decisions without being explicitly programmed to perform a task. These models ingest data, process it to find patterns and use this knowledge to deliver output.

Show question

Question

What are the three key types of Machine Learning models?

Show answer

Answer

The three key types of Machine Learning models are supervised learning, unsupervised learning, and reinforcement learning.

Show question

Question

How do supervised learning models work?

Show answer

Answer

In supervised learning, models are trained using labelled data, meaning they have knowledge of both input data and desired output. Examples include linear regression, logistic regression, decision trees, and random forests.

Show question

Question

How does unsupervised learning differ from supervised learning?

Show answer

Answer

Unlike supervised learning that uses labelled data, unsupervised learning deals with unlabeled data. Here, the model needs to make sense of the data on its own and extract useful insights. Examples include k-means and principal component analysis (PCA).

Show question

Question

What is a Neural Network in machine learning?

Show answer

Answer

A Neural Network in machine learning is a model that simulates the operations of a human brain to learn from large amounts of data. It contains layers of interconnected nodes, requiring initial training to adaptively learn.

Show question

Question

What are Support Vector Machines (SVM) used for in machine learning?

Show answer

Answer

Support Vector Machines (SVM) are supervised learning models used for classification and regression analysis. They are particularly proficient at separating data when the separation boundary isn't linear by transforming the data into higher dimensions.

Show question

Question

What underlying assumption does the Naive Bayes model in machine learning operate on?

Show answer

Answer

Naive Bayes operates on the assumption that each feature is independent of others which isn't necessarily always true, hence the name 'naive'.

Show question

Question

What is the process of model fitting in machine learning?

Show answer

Answer

Model fitting involves adjusting the model's parameters to minimise the discrepancy between predicted and target values. The aim is to tune the model to capture the underlying patterns and structure in the data.

Show question

Question

What are some common obstacles when training machine learning models?

Show answer

Answer

Some of the common obstacles include dealing with poor quality data, inadequate amount of data, overfitting and underfitting issues, and computational complexity and resources.

Show question

Question

How can the quality of the training data be improved?

Show answer

Answer

Quality of training data can be improved through data cleaning, data transformation and data augmentation.

Show question

Question

What are the solutions to acquire more data for training machine learning models?

Show answer

Answer

Using technologies like web scraping tools, APIs, or data augmentation techniques can aid in acquiring more training data.

Show question

Question

What are some solutions for managing computational resources while training machine learning models?

Show answer

Answer

Effective resource management can include using cloud computing solutions, efficient data storage formats, and applying dimensionality reduction techniques.

Show question

Question

What are deep learning models and how do they work?

Show answer

Answer

Deep learning models are a subclass of machine learning. They draw architecture and inspiration from the human brain to create artificial neural networks, and are designed to automatically and adaptively learn complex representations of data, thriving especially with high-dimensionality inputs.

Show question

Question

What is AutoML and what is it used for?

Show answer

Answer

AutoML refers to the automated process of model selection, hyperparameter tuning, iterative modelling, and model assessment. It aims to make machine learning more accessible to non-experts, improve expert efficiency and automate repetitive tasks.

Show question

Question

What is Distributed Machine Learning and why is it necessary?

Show answer

Answer

Distributed machine learning trains machine learning models on a cluster of computational resources, using parallel computing power. It is necessary for handling cases like real-time analytics and large-scale recommendation systems, where a single machine's memory and computational power may not suffice.

Show question

Question

What is real-time machine learning and what are its applications?

Show answer

Answer

Real-time machine learning processes data in real-time, makes instantaneous predictions, and adapts rapidly to changes in the data stream. It's widely used in chatbots, fraud detection, weather forecasting, and algorithmic trading.

Show question

Question

What is Supervised Learning in Machine Learning?

Show answer

Answer

Supervised Learning is a Machine Learning paradigm where the learning model is trained on labelled dataset. Its goal is to learn a function that, given an input, predicts the output for that input.
