Quant Trading using Machine Learning - Udemy

@machinelearnbot

The focus is on practically applying ML techniques to develop sophisticated Quant Trading models. Quant Trading: Quant Trading is a perfect example of an area where the use of Machine Learning leads to a step change in the quality of the models used. Traditional models often depend on Excel and building sophisticated models requires a huge amount of manual effort and domain knowledge. The only way to keep our prices this low is to *NOT offer additional technical support over email or in-person*.


Who needs mathematics and statistics for data science?

@machinelearnbot

Some background first: I have run teams of data scientists at large banks, I come from a physics and mathematics educational background, and I have taught data science. Some of the most important insights I have obtained in my career have come because of a deep understanding of metric spaces and n-dimensional manifolds. Advanced linear algebra has this hidden gems which no one knows about but gets to be drive insights from data using some python tools. Just went ahead, called the regression package on garbage data with no justification for what he was doing.


Predict the future with Machine Learning

#artificialintelligence

Fundamentally it is Software that works like our brain, learning from information (data), then applying it to make smart decisions. Ok let's dive head first into the 3 major types of algorithms in the field of Machine Learning; Supervised learning, Unsupervised learning and Reinforcement learning. One common clustering technique is called "k-means clustering", which aims to solve clustering problems. Bayesian Networks utilise graphs, probability theory and statistics to model real-world situations and infer data insights.


Artificial Intelligence Needs a Strong Data Foundation

#artificialintelligence

Similar to Maslow's hierarchy, data science advisor Monica Rogati has developed a similar pyramid to illustrate that while most firms are striving for the top of the data science hierarchy of needs (artificial intelligence), many more basic requirements must first be met. Remember, in many cases, the application of your AI and deep learning will be to improve the customer's banking experience, provide proactive financial recommendations and/or be applied to fraud and risk avoidance. Transforming data into insights is the highest stage that many financial services organizations ever reach in the data pyramid. But if you are collecting the needed real-time data, that is organized, clean, tested and optimized, it is time to test machine learning and artificial intelligence solutions.


Using artificial intelligence and machine learning to augment, not replace, cybersecurity capabilities Bloomberg Government

#artificialintelligence

While cybersecurity vendors add AI branding to their products, the reality is that a majority of today's solutions deliver subsets of AI capability – in particular, Machine Learning and Deep Learning. Machine Learning is used to create flexible multi-dimensional decision processes; supervised models capable of rapidly detecting and labeling new classes of threats, and unsupervised systems that learn the behaviors of a system or network over time and alert to attacker behaviors and rare threat events. Adopting and improving on decades-old "expert system" learning processes, security anomalies (false positive, true positive and unlabeled alerts) are initially responded to by a skilled security analyst, and their deduction processes and conclusions are learned by the system. Any technology that enables an analyst or threat responder to focus on the half-dozen critical events of the day (rather than distill 50,000 erroneous alerts generated each day) is viewed as a gift from above.


How do you bring artificial intelligence from the cloud to the edge?

#artificialintelligence

Blockchain can help IoT devices share compute resources in real-time and execute algorithms without the need for a round-trip to the cloud. Movidius' Myriad 2 vision processing unit (VPU) can be integrated into circuit boards to provide low-power computer vision and image signaling capabilities on the edge. One of the possible paths for bringing machine learning and deep learning algorithms closer to the edge is to lower their data and computation requirements. Though nothing short of general artificial intelligence will be able to rival the human brain, edge computing will enable AI applications to function in ways that are much closer to the way humans do.


How to Make AI Forget

#artificialintelligence

For example, a computer's working memory "forgets" data when it is no longer needed for a task, freeing up computational resources for other tasks. For example, connectionist AI (AI that often uses neural networks modelled on the structure of the brain) faces several problems related to "forgetting". These include over-fitting, which is when a learning machine stores overly detailed information from past experiences, hindering its ability to generalise and predict future events. An alternative approach to storing memories in robots is symbolic memory representations where knowledge is represented by logical facts ("birds fly", "Tweety is a bird", so therefore, "Tweety can fly").


FinTech, AI and the fourth Industrial Age

#artificialintelligence

To remain competitive, there is a growing need to use and master complex AI tools, adapt to new forms of convergence through collaboration and develop meaningful client relationships through new forms of customer centricity. Though banking has a long history of resisting modern methodologies -- agile development, cloud computing, advanced analytics, predictive onboarding, open platforms, hypertargeting and external data harvesting -- AI is one area the industry simply must embrace. If the FinTech industry fails to be more open to building new forms of customer value, efforts toward leveraging broader platforms will simply fail to materialize. Advanced tools now provide the industry with more capabilities to provide intelligent, personalized advice to offer new forms of customer advocacy beyond traditional services.


Bayesian A/B Testing Made Easy

#artificialintelligence

This method is somewhat lacking: it only leaves one with point estimates for the control and the treatment groups, and a verdict to reject (effect is observed) or to fail to reject (effect is not observed). Suppose that we have the current version and a proposed version of a web page, each containing a button of interest, and we wish to determine whether the proposed version leads to more clicks on the button of interest. To test this, we randomly assign some visitors to the current and other visitors to the proposed version. Now, let's simulate 20 observations for each group and compare the posterior probabilities for the control and treatment groups.


Why Businesses Should Embrace Machine Learning

#artificialintelligence

Google was the first company to realize the importance of incorporating machine learning in business processes. This is just one example of how machine learning processes in the recording and processing of data can help businesses grow. With the introduction of automated processes, businesses have become increasingly consumer-centric. Incorporating automated processes to record inventory stock and purchase order data is not a luxury, it's a necessity in today's world.
