Neural Networks: An Essential Beginners Guide to Artificial Neural Networks and Their Role in Machine Learning and Artificial Intelligence

There is a lot of coding and math behind neural networks, but the listener is presumed to have no prior knowledge or interest in either, so the concepts are broken down and elaborated on as such.  Each chapter is made as standalone as possible to allow the listener to skip back and forth without getting lost, with the glossary at the very end serving as a handy summary.  So if you want to learn about Neural Networks without having to go through heavy textbooks, listen to this audiobook now!

What is the difference between artificial intelligence, machine learning, active learning, and deep learning?

In his paper about using machine learning to teach a computer the game of checkers, Arthur Samuel introduces his research about the “programming of a digital computer to behave in a way which, if done by human beings or animals, would be described as involving the process of learning.” Eventually, the goal of ML is that “Programming computers to learn from experience should eventually eliminate the need for much of this detailed programming effort.” If AI is when a computer can carry out a set of tasks based on instruction, ML is a machine’s ability to ingest, parse, and learn from that data itself in order to become more accurate or precise about accomplishing that task.

While other statistical methods for learning exist, through recent ML advancements, practitioners have revived the concept of neural networks, which are a series of algorithms that act—as one might assume—like the human brain.  Machine learning is prevalent anywhere AI exists, but it has some specific use cases with which we may already be familiar.

The simplest definition for deep learning is that it is “a set of algorithms in machine learning that attempt to learn in multiple levels,” where the lower-level concepts help define different higher-level concepts.  Within a neural network, each processor or “neuron,” is typically activated through sensing something about its environment, from a previously activated neuron, or by triggering an event to impact its environment.

With deep learning, researchers implemented a “framework [that] takes images from a simple, inexpensive microscope and produces images that mimic those from more advanced and expensive ones.” Deep learning also often appears in the context of facial recognition software, a more comprehensible example for those of us without a research background.

Active learning is the philosophy that “a machine learning algorithm can achieve greater accuracy with fewer training labels if it is allowed to choose the data from which it learns.” In order to choose the data from which it learns, an active learning-based AI can ask queries of humans in order to obtain more data.  In situations where data is not readily available or and providing labels for that data is difficult, active learning poses a helpful solution.

In practice, the idea behind active learning is that data scientists can use poorly trained AI to help identify — through a Query Strategy, as outlined above — which pieces of data should be used to train a better version of that AI.  Human labelers are required for any sort of ML, but with Active Learning their work is significantly reduced by the machine selecting the most relevant data.

Expert Talk: Data Science vs. Data Analytics vs. Machine Learning

Data science, analytics, and machine learning are growing at an astronomical rate and companies are now looking for professionals who can sift through the goldmine of data and help them drive swift business decisions efficiently.

We caught up with Eric Taylor, Senior Data Scientist at CircleUp in a Simplilearn Fireside Chat to find out what makes data science such an exciting field and what skills will help professionals gain a strong foothold in this fast-growing domain.

Created by Hugh Conway in 2010, this Venn diagram consists of three circles - math and statistics, subject expertise (knowledge about the domain to abstract and calculate) and hacking skills.

A data scientist gathers data from multiple sources and applies machine learning, predictive analytics, and sentiment analysis to extract critical information from the collected data sets.

data analyst should be able to take a specific question or a specific topic and discuss what the data looks like and represent that data to relevant stakeholders in the company.

While a data scientist is expected to forecast the future based on past patterns, data analysts extract meaningful insights from various data sources.

Traditional machine learning software comprised of statistical analysis and predictive analysis that are used to spot patterns and catch hidden insights based on perceived data.

Data science is responsible for bringing structure to big data, searching compelling patterns, and finally advising decision makers to bring in the changes effectively to suit the business needs.
