Today, SVM is one of the most frequently used algorithms in machine learning, which is used in many practical applications, including medical diagnosis and weather forecasting.
Harnessing Neural Networks:
Deep learning has demonstrated impressive performance gain in many machine learning applications. However, unveiling and realizing these performance gains is not always straightforward. Discovering the right network architecture is critical for accuracy and often requires a human in the loop. Some network architectures occasionally produce spurious outputs, and the outputs have to be restricted to meet the needs of an application. Finally, realizing the performance gain in a production system can be difficult because of extensive inference times.
In this talk we discuss methods for making neural networks efficient in production systems. We also discuss an efficient method for automatically learning the network architecture, called AdaNet. We provide theoretical arguments for the algorithm and present experimental evidence for its effectiveness.

Differential Privacy and Machine Learning:
In this talk, we will give a friendly introduction to Differential Privacy, a rigorous methodology for analyzing data subject to provable privacy guarantees, that has recently been widely deployed in several settings. The talk will specifically focus on the relationship between differential privacy and machine learning, which is surprisingly rich. This includes both the ability to do machine learning subject to differential privacy, and tools arising from differential privacy that can be used to make learning more reliable and robust (even when privacy is not a concern).

Nearest Neighbor Methods And Vector Models: Vector models are being used in a lot of different fields: natural language processing, recommender systems, computer vision, and other things. They are fast and convenient and are often state of the art in terms of accuracy. One of the challenges with vector models is that as the number of dimensions increase, finding similar items gets challenging. Erik developed a library called “Annoy” that uses a forest of random tree to do fast approximate nearest neighbor queries in high dimensional spaces. We will cover some specific applications of vector models with and how Annoy works.

Machine Learning Heresy and the Church of Optimality:
As Machine Learning continues to grow in both usage and impact on people’s lives, there has been a growing concern around the ethics of using these systems. In application areas such as hiring selection, loan review, and even prison sentencing, ML is being used in ways that raise questions about the fairness of these algorithms. But what does it mean for an algorithm to be fair? An algorithm will consistently make the same decision when given the same data, leading some people to argue that building an optimal algorithm is inherently fair. Even in the case of using sensitive features like age, race and gender, if the data is predictive, aren’t we just modeling reality?
In this talk, I will argue that these questions do not let us off the hook in regards to the impact of the systems we build as Machine Learning engineers. I think it is important to question the nature of how ‘optimal’ a model can even be in the first place. Finally, I will discuss what kinds of organizational resistance engineers might run into, and how to deal with questionable ethical decisions for the sake of being ‘optimal’.

Fault-tolerable Deep Learning on General-purpose Clusters:
Researchers have been used to running deep learning jobs on clusters. In industrial applications, AI is built on top of big data and deep learning is only one stage of the data pipeline. That is where MPI-based clusters are not enough, and general-purpose cluster management systems are necessary to run Web servers like Nginx, log collectors like fluentd and Kafka, data processors on top of Hadoop, Spark, and Storm, and deep learning, which improves the Web service quality. This talk explains how we integrate PaddlePaddle and Kubernetes to provide an open source fault-tolerable large-scale deep learning platform.

Predictability and other Predicaments:
In the context of building predictive models, predictability is usually considered a blessing. After all – that is the goal: build the model that has the highest predictive performance. The rise of ‘big data’ has in fact vastly improved our ability to predict human behavior thanks to the introduction of much more informative features. However, in practice things are more differentiated than that. For many applications, the relevant outcome is observed for very different reasons. In such mixed scenarios, the model will automatically gravitate to the one that is easiest to predict at the expense of the others. This even holds if the predictable scenario is by far less common or relevant. We present a number of applications where this happens: clicks on ads being performed ‘intentionally’ vs. ‘accidentally’, consumers visiting store locations vs. their phones pretending to be there, and finally customers filling out online forms vs. bots defrauding the advertising industry. In conclusion, the combination of different and highly informative features can have significantly negative impact on the usefulness of predictive modeling.

The Future of Kaggle: Where We Came From and Where We’re Going:
Kaggle started off running supervised machine learning competitions. This attracted a talented and diverse community that now has nearly one million members. It’s exposed us to hundreds of machine learning usecases, introduced hundreds of thousands to machine learning, and helped push the state of the art forward. We’ve expanded by launching an open data platform, Kaggle Datasets, along with a reproducible and collaborative machine learning platform, Kaggle Kernels. They have already achieved strong adoption by our community by making it simpler to get started with, share, and collaborate on data and code.
We’ve achieved less than 1% of what we’re capable of. Several weeks ago we launched an announced an acquisition by Google. This enables us to move forward more rapidly and ambitiously. Working with analytics and machine learning is fraught with pain right now. It’s the software engineering equivalent of programming in assembly. It’s tough to access data. It’s tough to collaborate. It’s tough to reproduce results. We’ve seen these pain points over, and over, and over again. We’ve seen them in how our customer’s internal teams function. We’ve experienced them collaborating with our customers. We’ve seen them as people approach our competitions individually, and they become even more pronounced when our users team up. We want to solve this, and foster an era of intelligent services that improve your lives every single day.
In this talk, I’ll go into depth on the lessons we’ve learned from running Kaggle and the most frustrating pain points we’ve seen. I’ll discuss how you can ameliorate these by leveraging current open source tools and technologies, and wrap up by painting a picture of the future we’re building towards.

What color should that button be to convert more sales? What ad will most likely get clicked on? What movie recommendations should be displayed to keep subscribers engaged? What should we have for lunch? These are all examples of iterated decision problems — the same choice has to be made repeatedly with the goal being to arrive at an optimal decision strategy by incorporating the results of the previous decisions. In this talk I will describe the Bayesian Bandit solution to these types of problems, how it adaptively learns to minimize regret, how additional contextual information can be incorporated, and how it compares to the more traditional A/B testing solution.

Surveillance platforms for bank compliance
Bank compliance uses models to look for outlier events such as insider trading, spoofing, front running, etc. With the exponential increase in the size of the data and a growing need to use such models, a key question is: How do we scale these models so they run efficiently and at the same time detect outlier events with good precision and recall?
In this talk, we will describe our experience building, from scratch, a Hadoop-based platform for surveillance.

Precision agriculture – Predicting outcomes for farmers using machine learning to help feed the world:
Agricultural data is vast, often unstructured and includes many challenges when working with legacy farm systems on premise in rural areas. For instance, traditional farm equipment such as tractors, sprayers, and combines aren’t often from the same vendor, and it’s complex moving data between them. This is further complicated with the vast array of other systems used by our farmers. Furthermore, the number of sensors in agriculture is astonishing, whether it is sensors that measure the gait of the cow walking into the dairy parlor, or chickens that are pecking. All this data needs to turn into usable information on a global scale to improve the yields farmers get and provide greater visibility into what’s going on both in and out of the farm. In this session, a case study will be shared on how data was collected, normalized and analyzed leveraging the open source HPCC Systems platform from remote Farm Management Systems (used by farmers to manage their farms), and when merged with weather data, soil data and actual machinery data, the analyzed predictions is used to feed Agronomists and Crop Protection/Seed Manufacturers to get recommendations back. The goal is to deliver a precision agriculture solution, helping farmers increase their yield, which then helps feed the growing population of the world.
