"Many researchers … speculate that the information-processing abilities of biological neural systems must follow from highly parallel processes operating on representations that are distributed over many neurons. [Artificial neural networks] capture this kind of highly parallel computation based on distributed representations"

Hepatocellular carcinoma (HCC) currently represents the fifth most common malignancy and the third-leading cause of cancer-related death worldwide, with incidence and mortality rates that are increasing. Recently, artificial intelligence (AI) has emerged as a unique opportunity to improve the full spectrum of HCC clinical care, by improving HCC risk prediction, diagnosis, and prognostication. AI approaches include computational search algorithms, machine learning (ML) and deep learning (DL) models. ML consists of a computer running repeated iterations of models, in order to progressively improve performance of a specific task, such as classifying an outcome. DL models are a subtype of ML, based on neural network structures that are inspired by the neuroanatomy of the human brain.
I have recently started exploring Neural networks, and I came across the term activation function and biases. Activation function kinda made some sense to me, but I found it difficult to get the exact essence of biases in Neural Network. Bias in Neural Networks can be thought of as analogous to the role of an intercept in linear regression. But what the heck does this mean? I very well understand that intercept is the point where the line crosses the y-axis.

Many companies use machine learning to help create a differentiator and grow their business. However, it's not easy to make machine learning work as it requires a balance between research and engineering. One can come up with a good innovative solution based on current research, but it might not go live due to engineering inefficiencies, cost and complexity. Most companies haven't seen much ROI from machine learning since the benefit is realized only when the models are in production. Let's dive into the challenges and best practices that one can follow to make machine learning work.
Machine learning is rapidly evolving and the crucial focus of the software development industry. The infusion of artificial intelligence with machine learning has been a game-changer. More and more businesses are focusing on wide-scale research and implementation of this domain. Machine learning provides enormous advantages. It can quickly identify patterns and trends and the concept of automation comes to reality through ML.
The "black-box" conundrum is one of the biggest roadblocks preventing banks from executing their artificial intelligence (AI) strategies. It's easy to see why: Picture a large bank known for its technology prowess designing a new neural network model that predicts creditworthiness among the underserved community more accurately than any other algorithm in the marketplace. This model processes dozens of variables as inputs, including never-before-used alternative data. The developers are thrilled, senior management is happy that they can expand their services to the underserved market, and business executives believe they now have a competitive differentiator. But there is one pesky problem: The developers who built the model cannot explain how it arrives at the credit outcomes, let alone identify which factors had the biggest influence on them.
Projects have always been thought of as measurable improvements resulting from a result produced, which serve as the icing on the cake for achieving personal or corporate goals. Talking about individual projects, have you found it challenging to learn at home? Many of us are in the same boat -- there are far too many things to handle during these trying times, and learning has taken a back seat, contrary to our expectations. So, what are our options for getting back on track? How can we apply what we have learned about data science in the real world? Picking an open-source data science project and sticking with it is extremely beneficial.
Artificial intelligence researchers are doubling down on the concept that we will see artificial general intelligence (AGI) -- that's AI that can accomplish anything humans can, and probably many we can't -- within our lifetimes. Responding to a pessimistic op-ed published by TheNextWeb columnist Tristan Greene, Google DeepMind lead researcher Dr. Nando de Freitas boldly declared that "the game is over" and that as we scale AI, so too will we approach AGI. Greene's original column made the relatively mainstream case that, in spite of impressive advances in machine learning over the past few decades, there's no way we're gonna see human-level artificial intelligence within our lifetimes. But it appears that de Freitas, like OpenAI Chief Scientist Ilya Sutskever, believes otherwise. "Solving these scaling challenges is what will deliver AGI," the DeepMind researcher tweeted, later adding that Sutskever "is right" to claim, quite controversially, that some neural networks may already by "slightly conscious."
This article was published as a part of the Data Science Blogathon. As a consequence of the large quantity of data accessible, particularly in the form of photographs and videos, the need for Deep Learning is growing by the day. Many advanced designs have been observed for diverse objectives, but Convolution Neural Network – Deep Learning techniques are the foundation for everything. So that'll be the topic of today's piece. Deep learning is a machine learning and artificial intelligence (AI) area that mimics how people learn.
