Predicting best quality of wine using Linear Regression and PyTorch

#artificialintelligence

In this notebook we will predict the best quality of the wine using PyTorch and linear regression. If you haven't checked out my previous blog on Linear Regression check this out . First of all lets import required libraries.. Now lets analyse our dataset.. its important to analyse to see what we are dealing with.. Training Dataset: The sample of data used to fit the model. The actual dataset that we use to train the model (weights and biases in the case of a Neural Network). The model sees and learns from this data.


Clustering U.S counties by their COVID-19 curves

#artificialintelligence

Analytics has become a part of everyone's daily routine as a result of the pandemic. Every day we look at curves of new cases, positivity rates, and a range of other metrics that give us insight into our current situation. One interesting metric used by the CDC, along with many news networks and publications is hotspot classification. A hotspot is a county or state where cases are currently increasing at a relatively high rate [1]. This metric is simple and easy to understand. But it leaves out a lot of interesting details.

The unreasonable effectiveness of synthetic data with Daeil Kim

#artificialintelligence

The hard part is diversifying the content. So if we just have the same character in an environment doing everything, it's not going to work, right? So how do you actually create hundreds or thousands of variations of that character model with different behavior and things like that? That's been really the core focus of how we're thinking about our technology. You're listening to Gradient Dissent, a show where we learn about making machine learning models work in the real world. Daeil Kim is the co-founder and CEO of AI.Reverie. A startup that specializes in creating high quality synthetic training data for computer vision algorithms. Before that he was a senior data scientist at the New York Times. And before that he got his PhD in computer science from Brown university, focusing on machine learning and Bayesian statistics. He's going to talk about tools that will advance machine learning progress, and he's going to talk about synthetic data. I'm super excited for this. I was looking at your LinkedIn and you have a little bit of an unusual path, right? You did a liberal arts undergrad. Can you say a little bit about... I feel like I come across people quite a lot that want to make career transitions into machine learning and related fields. What was that for you? What prompted you to do it?


Machine Learning -- K-Nearest Neighbors algorithm with Python

#artificialintelligence

'K-Nearest Neighbors (KNN) is a model that classifies data points based on the points that are most similar to it. It uses test data to make an "educated guess" on what an unclassified point should be classified as' We will be building our KNN model using python's most popular machine learning package'scikit-learn'. Scikit-learn provides data scientists with various tools for performing machine learning tasks. For our KNN model, we are going to use the'KNeighborsClassifier' algorithm which is readily available in scikit-learn package. Finally, we will evaluate our KNN model predictions using the'accuracy score' function in scikit-learn.


Beginner's Guide to K-Nearest Neighbors in R: from Zero to Hero

#artificialintelligence

In the world of Machine Learning, I find the K-Nearest Neighbors (KNN) classifier makes the most intuitive sense and easily accessible to beginners even without introducing any math notations. To decide the label of an observation, we look at its neighbors and assign the neighbors' label to the observation of interest. Certainly, looking at one neighbor may create bias and inaccuracy, and the KNN method has a set of rules and procedures to determine the best number of neighbors, e.g., examining k 1 neighbors and adopt majority rule to decide the category. "To decide the label for new observations, we look at the closest neighbors." To choose the nearest neighbors, we have to define what distance is.


The Various Types of Artificial Intelligence Technologies

#artificialintelligence

Artificial Intelligence is a broad term that encompasses many techniques, all of which enable computers to display some level of intelligence similar to us humans. The most popular use of Artificial Intelligence is robots that are similar to super-humans at many different tasks. They can fight, fly, and have deeply insightful conversations about virtually any topic. There are many examples of robots in movies, both good and bad, like the Vision, Wall-E, Terminator, Ultron, etc. Though this is the holy grail of AI research, our current technology is very far from achieving that AI level, which we call General AI.


Most Popular Distance Metrics Used in KNN and When to Use Them - KDnuggets

#artificialintelligence

KNN is the most commonly used and one of the simplest algorithms for finding patterns in classification and regression problems. It is an unsupervised algorithm and also known as lazy learning algorithm. It works by calculating the distance of 1 test observation from all the observation of the training dataset and then finding K nearest neighbors of it. This happens for each and every test observation and that is how it finds similarities in the data. For calculating distances KNN uses a distance metric from the list of available metrics.


K-Means for Cluster Analysis and Unsupervised Learning in R

#artificialintelligence

Preview this course - GET COUPON CODE Learn why and where K-Means is a powerful tool Clustering is a very important part of machine learning. Especially unsupervised machine learning is a rising topic in the whole field of artificial intelligence. If we want to learn about cluster analysis, there is no better method to start with, than the k-means algorithm. Unlike other courses, it offers NOT ONLY the guided demonstrations of the R-scripts but also covers theoretical background that will allow you to FULLY UNDERSTAND & APPLY UNSUPERVISED MACHINE LEARNING (K-means) in R. Get a good intuition of the algorithm The K-Means algorithm is explained in detail. We will first cover the principle mechanics without any mathematical formulas, just by visually observing data points and clustering behavior.
