Vision science has always developed models at smaller scales than the frontier of artificial intelligence. This is partially because of the academic roots of vision science, partially because of a well-founded desire to lean on reductionism to truly understand how vision works, and partially because attempts at incorporating biological inspiration into DNNs have been hamstrung by implementations that are poorly suited for GPUs. For example, most attempts at biologically-inspired DNNs have focused on inducing architectural constraints like recurrence [34,61,116-118] and different forms of feedback [59,60] that are not explicitly included in DNNs but known to play key roles in primate vision [119-123] . While we believe these approaches are important for Neuroscience and especially for constraining model hypothesis spaces in small data settings, the methods used for implementation are undeniably challenging to scale [118,124] and it is possible that the induced computational strategies could be learned by a less-constrained DNN trained with the "right" data and objective [125] . Thus, it may be that a more effective approach to reverse-engineering vision than hand-designing small-scale recurrent DNNs could be to train DNNs at large scales with approximations of the kinds of data and routines that shape biological visual systems.

Natural disasters affect almost every part of the world. In 2018, Indonesia faced the highest number of deaths in the world due to the earthquakes and tsunami that occurred in September. In the United States that year, most of fatalities from natural disasters came from tropical cyclones, wildfires, heat, and drought. Social media is being explored as tool for disaster management by developers, researchers, government agencies and businesses. The disaster-affected area requires both cautionary and disciplinary measures.

Numerai is a machine learning stock market prediction platform seeking to build the world's largest hedge fund. The project continuously runs "the hardest data science tournament on the planet" with the goal of crowdsourcing an excellent financial model for predicting the stock market, among other things. Now, before we dive in, the following piece is similar to my latest articles on Hegic (HEGIC), Ocean Protocol (OCEAN), and Quantstamp (QSP), so if you haven't already seen those, be sure to check them out as well. Numerai is a unique project that's tackling a complicated data science problem by crowdsourcing data scientists who are provided with clean and regularized stock market data that has been encrypted and obfuscated so it can be given out for free. Users (data scientists) who sign up with Numerai can download their cleaned data to create models that predict stock market movements.

Earlier this month I was figuring out how to code a recurrent neural network (RNN, a common form of neural networks for text generation) to rewrite its own code. The idea was to train the RNN to completion, then to take code it generated (with syntax checks, of course) and run it. The code that the RNN generated would serve the purpose of generating more code to generate more RNNs, and so on, with each new'generation' of RNN coding the next. I was incredibly excited to see how it would turn out --the idea is exciting to entertain. An AI trained to improve itself will inevitably do so, right?

It will also provide information about missing values or outliers if any. For more information and functions which you can use read beginner's guide to exploratory data analysis. Both missing values and outliers are of concern for Machine Learning models as they tend to push the result towards extreme values.

There are many metrics to measure the performance of your machine learning model depending on the type of machine learning you are looking to conduct. In this article, we take a look at performance measures for classification and regression models and discuss which is better-optimized. Sometimes the metric to look at will vary according to the problem that is initially being solved. The True Positive Rate, also called Recall, is the go-to performance measure in binary/non-binary classification problems. Most of the time -- if not all of the time -- we are only interested in correctly predicting one class.

According to a recent investigation, an estimated 33-50% of the world's coral reefs have undergone degradation, believed to be as a result of climate change. A strong driver of climate change and the subsequent environmental impact are greenhouse gases such as methane. However, the exact relation climate change has to the environmental condition cannot be easily established. Remote sensing methods are increasingly being used to quantify and draw connections between rapidly changing climatic conditions and environmental impact. A crucial part of this analysis is processing spectroscopy data using radiative transfer models (RTMs) which is a computationally expensive process and limits their use with high volume imaging spectrometers. This work presents an algorithm that can efficiently emulate RTMs using neural networks leading to a multifold speedup in processing time, and yielding multiple downstream benefits.

We are in the middle of an AI boom. Machine Learning experts command extraordinary salaries, investors are happy to open their hearts and checkbooks when meeting AI startups. And rightly so: this is one of those transformational technologies that occur once per generation. The tech is here to stay, and it will change our lives. That doesn't mean that making your AI startup succeed is easy. I think there are some important pitfalls ahead of anyone trying to build their business around AI. In 2015 I was still at Google and started playing with DistBelief (which they would later rename to TensorFlow).
