Machine learning is a subfield of computer science where machines are trained to make decisions with the help of data provided without any human interference. For example, if we could teach a computer to tell if a person is lying about something, then the computer might be using machine learning as software. There are huge applications of machine learning such as Face recognition, image classification, stock market prediction, Emotion detection, self-driving cars, etc. More details about all these are covered in the training course videos. Machine learning uses knowledge from mathematics, statistics, computer science, and programming to build and deploy algorithms that can do one of those tasks mentioned above.

In this latest Data Science Central webinar, Dan Chaney, (VP of Enterprise AI & Data Science Solutions, Future Tech Enterprise, Inc.) and Lenny Isler, (Business Development, Advanced Computing Solutions, for HPi), discuss the key internal challenges that companies face when trying to manage their AI programs and align various stakeholders - business leadership, IT, and data science team members - around common objectives and business goals.

When it comes to the education landscape, the entire industry has undergone a rapid transformation in recent times. The next-gen technologies, including Artificial Intelligence and Machine learning, have portrayed their true potential in all industry verticals globally. As per a recent report, the global AI software market is forecast to reach 126 billion U.S. dollars by 2025. When every other industry is reaping the benefits from AI & ML, the education industry is no different. Artificial intelligence and machine learning in the education sector are acting as the driving force and have added value as never before.

There are many situations where using a depth camera as input into a machine learning system can offer additional benefits and features – as we previously discussed in a prior blog post "What does Depth Bring to Machine Learning." Depth cameras have a number of advantages for a variety of machine learning problems, including lighting invariance. Depth cameras can easily adapt to a wide variety of lighting conditions, something that 2D models must be trained to compensate for. A depth camera also allows differentiation between items of different size as well as easier background segmentation, allowing the separation of individual items regardless of how complicated the background is. One of the main problems facing those wishing to use depth cameras for machine learning projects at the current time is the lack of significant training datasets, when compared with the existing libraries and models based on many thousands of 2d images. Given how complex machine learning is, it's useful to have frameworks that assist with acquiring datasets, building models and implementing them.

There is mounting public concern over the influence that AI based systems has in our society. Coalitions in all sectors are acting worldwide to resist hamful applications of AI. From indigenous people addressing the lack of reliable data, to smart city stakeholders, to students protesting the academic relationships with sex trafficker and MIT donor Jeffery Epstein, the questionable ethics and values of those heavily investing in and profiting from AI are under global scrutiny. There are biased, wrongful, and disturbing assumptions embedded in AI algorithms that could get locked in without intervention. Our best human judgment is needed to contain AI's harmful impact. Perhaps one of the greatest contributions of AI will be to make us ultimately understand how important human wisdom truly is in life on earth.

Pattern discovery, the process of discovering previously unrecognized patterns, is often performed as an ad-hoc process with little resulting certainty in the quality of the proposed patterns. Pattern validation, the process of validating the accuracy of proposed patterns, remains dominated by the simple heuristic of "the rule of three". This article shows how to use established scientific research methods for the purpose of pattern discovery and validation. We present a specific approach, called the handbook method, that uses the qualitative survey, action research, and case study research for pattern discovery and evaluation, and we discuss the underlying principle of using scientific methods in general. We evaluate the handbook method using three exploratory studies and demonstrate its usefulness.

Many machine learning models have been built to tackle information overload issues on Massive Open Online Courses (MOOC) platforms. These models rely on learning powerful representations of MOOC entities. However, they suffer from the problem of scarce expert label data. To overcome this problem, we propose to learn pre-trained representations of MOOC entities using abundant unlabeled data from the structure of MOOCs which can directly be applied to the downstream tasks. While existing pre-training methods have been successful in NLP areas as they learn powerful textual representation, their models do not leverage the richer information about MOOC entities. This richer information includes the graph relationship between the lectures, concepts, and courses along with the domain knowledge about the complexity of a concept. We develop MOOCRep, a novel method based on Transformer language model trained with two pre-training objectives : 1) graph-based objective to capture the powerful signal of entities and relations that exist in the graph, and 2) domain-oriented objective to effectively incorporate the complexity level of concepts. Our experiments reveal that MOOCRep's embeddings outperform state-of-the-art representation learning methods on two tasks important for education community, concept pre-requisite prediction and lecture recommendation.

How to Learn Machine Learning – Tips and Resources to Learn ML the Practical Way Yacine Mahdid A lot of people want to learn machine learning these days. But the daunting bottom-up curriculum that most ML teachers propose is enough discourage a lot of newcomers. In this tutorial I flip the curriculum upside down and will outline what I think is the fastest and easiest way to get a solid grasp of ML. Table of Contents Step 6: Repeat steps 0 to 5 This is a looping learning plan because the 6th step is actually a GOTO to Step 0! As a disclaimer, this curriculum might strange to you. But I've battle tested it when I was teaching machine learning to undergraduates at McGill University. I tried many iteration of this curriculum, starting with the theoretically superior bottom-up approach. But from experience, this pragmatic top-down approach is what gives the best results. One common critique I get is that people not starting with the basics, like statistics or linear algebra, will have a poor understanding of machine learning and they will not know what they are doing when modeling. In theory, yes, this is true and this is why I started teaching ML with the bottom up approach. In practice, this has never been the case. What actually ended up happening was that because the students knew how to do the high level modeling, they were much more inclined to delve into the low level stuff on their own as they saw the direct benefit it would bring to their higher level skills. This context that they were able to set for themselves wouldn't have been there if they'd started from the bottom – and this is where I believe most teachers lose their students. All that being said, let's jump into the actual learning plan!

The ETL (extract, transform, load) process is the most popular method of collecting data from multiple sources and loading it into a centralized data warehouse. ETL is an essential component of data warehousing and analytics. Pentaho has phenomenal ETL, data analysis, metadata management and reporting capabilities. Pentaho is faster than other ETL tools (including Talend). Pentaho has a user-friendly GUI which is easier and takes less time to learn.
