Three-way data splits (training, test and validation) for model selection and performance estimation
The use of training, validation and test datasets is common but not easily understood. In this post, I attempt to clarify this concept. The post is part of my forthcoming book on learning Artificial Intelligence, Machine Learning and Deep Learning based on high school maths. And then comes up with an important statement: Reference to a "validation dataset" disappears if the practitioner is choosing to tune model hyperparameters using k-fold cross-validation with the training dataset. Model selection: involves selecting optimal parameters or a model.
InceptionTime: Finding AlexNet for Time Series Classification
Time series classification (TSC) is the area of machine learning interested in learning how to assign labels to time series. The last few decades of work in this area have led to significant progress in the accuracy of classifiers, with the state of the art now represented by the HIVE-COTE algorithm. While extremely accurate, HIVE-COTE is infeasible to use in many applications because of its very high training time complexity in O(N 2*T 4) for a dataset with N time series of length T. For example, it takes HIVE-COTE more than 72,000s to learn from a small dataset with N 700 time series of short length T 46. Deep learning, on the other hand, has now received enormous attention because of its high scalability and state-of-the-art accuracy in computer vision and natural language processing tasks. Deep learning for TSC has only very recently started to be explored, with the first few architectures developed over the last 3 years only.
AI learns to defy the laws of physics to win at hide-and-seek
Never play games with a bot โ it will find a way to cheat if they can. A team from OpenAI, an artificial intelligence lab in San Francisco co-founded by Elon Musk, has developed artificially intelligent bots that taught themselves to cooperate by playing hide-and-seek. The bots also learned how to use basic tools and that defying the laws of physics can help you win. In April, a team of bots known as the OpenAI Five beat the human world champions at the team-based video game DOTA 2. The hide-and-seek bots use similar principles to learn but the simpler game allows for more inventive play. Bowen Baker at OpenAI and his colleagues wanted to see if the team-based dynamics of the OpenAI Five could be used to generate skills that could one day be useful to humans.
Reimagining Plutarch with Tensorflow 2.0
In the model summary we'll see that the number of parameters for the embedding layer is 2,024,200, which is 20,242 words times the embedding dimension of 100. The previously mentioned TensorFlow tutorial is using a reviews dataset with each of the reviews being labeled 1 or 0 depending on the positive or negative sentiment. We do not have the labeling luxury but still want to test drive this model, so will simply create an array of 0s and attach to each of the sentences; the model requires such a structure. This will not be the first or the last time that machine intelligence gets assaulted with an unsolvable task yet still obliges us with a solution.
Reinforcement Learning Tutorial with Open AI Gym
The more I learn, the less I realize I know. This blog is the Part-2 of the series on reinforcement learning. Feel free to read the part-1 here. In this article I will be implementing OpenAI Gym's Bipedal Walker environment using Deep Deterministic Policy Gradient (DDPG) algorithm. OpenAI Gym is a toolkit for developing and comparing reinforcement learning algorithms.

The best AI quotes of all time are the ones that resonate with people in a way that the world will never forget. They're the kind of wisdom that smacks you in the face and encourages you to be all you can be. Here, I have compiled a list of 10 of the best Artificial Intelligence quotes of all time.
On Education Tensorflow 2.0: Deep Learning and Artificial Intelligence - all courses
It's been nearly 4 years since Tensorflow was released, and the library has evolved to its official second version. Tensorflow is Google's library for deep learning and artificial intelligence. Deep Learning has been responsible for some amazing achievements recently, such as: Generating beautiful, photo-realistic images of people and things that never existed (GANs) Beating world champions in the strategy game Go, and complex video games like CS:GO and Dota 2 (Deep Reinforcement Learning) Self-driving cars (Computer Vision) Speech recognition (e.g. Siri) and machine translation (Natural Language Processing) Even creating videos of people doing and saying things they never did (DeepFakes - a potentially nefarious application of deep learning) Tensorflow is the world's most popular library for deep learning, and it's built by Google, whose parent Alphabet recently became the most cash-rich company in the world (just a few days before I wrote this). It is the library of choice for many companies doing AI and machine learning.
Meet Five Synthetic Biology Companies Using AI To Engineer Biology
TVs and radios blare that "artificial intelligence is coming," and it will take your job and beat you at chess. But AI is already here, and it can beat you -- and the world's best -- at chess. In 2012, it was also used by Google to identify cats in YouTube videos. Today, it's the reason Teslas have Autopilot and Netflix and Spotify seem to "read your mind." Now, AI is changing the field of synthetic biology and how we engineer biology.
Intel Unveils Powerful New Nervana NNP AI Chips For Inferencing And Training With Up To 32GB HBM2
Like just about every other major technology firm, Intel sees a lot of promise in artificial intelligence, and is making investments in the category. That is on display today at the Hot Chips conference, where Intel unveiled the first two processors comprising its Nervana Neural Network (NNP) line, including one for training (NNP-T) and one for inference (NNP-I). Dubbed "Spring Crest," Intel built its Nervana NNP-T from the ground up to train deep learning models at scale. It is designed to prioritize training networks as quickly as possible, and do it within a given power budget, Intel says. The chip is also designed with flexibility in mind, to offer a balance between compute, communication, and memory, and is optimized for batched workloads.
A superpixel-driven deep learning approach for the analysis of dermatological wounds
The image-based identification of distinct tissues within dermatological wounds enhances patients' care since it requires no intrusive evaluations. This manuscript presents an approach, we named QTDU, that combines deep learning models with superpixel-driven segmentation methods for assessing the quality of tissues from dermatological ulcers.
