Recently, I decided to hold a series of workshops about Java development at the CoderDojo Linz. As lots of kids and teens there enjoy playing Minecraft, it was a straightforward decision to choose Minecraft plugin development as the topic for these workshops. As I never played Minecraft before, I wanted to get to know the game first. My plan to play for 2 or 3 hours to learn the basics escalated rather quickly and I ended up not being productive for a week. Well, probably I could have anticipated that. Anyway, now I'm back and in the following section, I summarized some basics about Minecraft plugin development with Bukkit. Please note that this guide assumes, that you are already familiar with Java. If you are new to Java, I'd recommend getting to know Java first. Here you can find some great resources to learn it.

There are a vast number of different types of data preparation techniques that could be used on a predictive modeling project. In some cases, the distribution of the data or the requirements of a machine learning model may suggest the data preparation needed, although this is rarely the case given the complexity and high-dimensionality of the data, the ever-increasing parade of new machine learning algorithms and limited, although human, limitations of the practitioner. Instead, data preparation can be treated as another hyperparameter to tune as part of the modeling pipeline. This raises the question of how to know what data preparation methods to consider in the search, which can feel overwhelming to experts and beginners alike. The solution is to think about the vast field of data preparation in a structured way and systematically evaluate data preparation techniques based on their effect on the raw data.

Inheritance is a method in object-oriented programming to make subclass similar to the main classes so that the subclass inherits properties from main classes. The main reason why we use inheritance is the re-usability of code. Single inheritance means when a subclass inherits properties from only one main class. For example, we can take the properties of the house. To access the methods or functions or features of classes we have to make an object of that class.

Adversarial attacks on machine learning-based classifiers, along with defense mechanisms, have been widely studied in the context of single-label classification problems. In this paper, we shift the attention to multi-label classification, where the availability of domain knowledge on the relationships among the considered classes may offer a natural way to spot incoherent predictions, i.e., predictions associated to adversarial examples lying outside of the training data distribution. We explore this intuition in a framework in which first-order logic knowledge is converted into constraints and injected into a semi-supervised learning problem. Within this setting, the constrained classifier learns to fulfill the domain knowledge over the marginal distribution, and can naturally reject samples with incoherent predictions. Even though our method does not exploit any knowledge of attacks during training, our experimental analysis surprisingly unveils that domain-knowledge constraints can help detect adversarial examples effectively, especially if such constraints are not known to the attacker. While we also show that an adaptive attack exploiting knowledge of the constraints may still deceive our classifier, it remains an open issue to understand how hard for an attacker would be to infer such constraints in practical cases. For this reason, we believe that our approach may provide a significant step towards designing robust multi-label classifiers.

Question-answering (QA) is certainly the best known and probably also one of the most complex problem within Natural Language Processing (NLP) and artificial intelligence (AI). Since the complete solution to the problem of finding a generic answer still seems far away, the wisest thing to do is to break down the problem by solving single simpler parts. Assuming a modular approach to the problem, we confine our research to intent classification for an answer, given a question. Through the use of an LSTM network, we show how this type of classification can be approached effectively and efficiently, and how it can be properly used within a basic prototype responder. Keywords: Deep Learning, LSTM, Intent classification, Question-Answering 1 Introduction Despite the remarkable results obtained in the different areas of Natural Language Processing, the solution to the Question-Answering problem, in its general sense, still seems far away [1].

Overview We are looking for talents who can use NLP&ML to make a text classification program for us. Classification standard: There are 22 main classes about different industries according to our classification standard. Under every main class are some subclasses. Every inputted text should be put into at least one of the 170 classes. A text can be put into 2 classes (maximum) if the two classes are both related.
