Grammarly AI-NLP Club #2 - Recent advances in applied chatbot technology - Jo...Grammarly
Speaker: Jordi Carrera Ventura, Artificial Intelligence technologist at Telefónica R&D
Summary: Chatbots (aka conversational agents, spoken dialogue systems) allow users to interface with computers using natural language by simply asking questions or issuing commands.
Given a query, the chatbot builds a semantic representation of the input, transforms it into a logical statement, and performs all the necessary actions to fulfill the user's intent. Sometimes this simply means calculating an exact answer or retrieving a fact from a database, whereas other times it means building a contextual model and running a full-fledged conversation flow while keeping track of anaphoras and cross-references.
Besides the direct applications of chatbots in IoT (Amazon’s Alexa, Apple's Siri) and IT (the historical field of Information Retrieval as a whole can be seen as a sub-problem of spoken dialogue systems), chatbots' main appeal for technologists is their location at the intersection of all major Natural Language Processing technologies and many of the deepest questions in Cognitive Science today: semantic parsing, entity recognition, knowledge representation, and coreference resolution.
In this talk, I will explore those questions in the context of an applied industry setting, and I will introduce a framework suitable for addressing them, together with an overview of the state-of-the-art in chatbot technology and some original techniques.
EuroPython 2019: Modern Continuous Delivery for Python DevelopersPeter Bittner
Deployment automation, cloud platforms, containerization, short iterations to develop and release software—we’ve progressed a lot. And finally it’s official: Kubernetes and OpenShift are the established platforms to help us do scaling and zero downtime deployments with just a few hundred lines of YAML. It’s a great time.
Can we finally put all our eggs into one basket? Identify the cloud platform that fits our needs, and jump on it? That could well backfire: Vendor lock-in is the new waterfall, it slows you down. In future you’ll want to jump over to the next better platform, in a matter of minutes. Not months.
This talk is about The Art of Writing deployment pipelines that will survive Kubernetes, OpenShift and the like. It’s for Python developers and Kubernetes enthusiasts of all levels – no domain specific knowledge required, all you need to understand will be explained. You’ll learn how to separate application-specific and deployment-specific configuration details, to maximize your freedom and avoid vendor lock-in.
Come see a demo of a Django project setup that covers everything from local development to automatic scaling, flexible enough to be deployed on any of your favorite container platforms. Take home a working, future-proof setup for your Python applications.

Continuous Delivery for Python Developers – PyCon OttoPeter Bittner
Continuous Delivery sounds easy in theory, but it’s hard to do in practice. There are myriads of things you can and should do to get your code delivered faster, reliably. We look at what we can do as Python developers, or as a small or mid-sized team to make the industrialized software development production chain come true.
Pack is a one-stop solution for packaging, distributing and deploying applications. It is able to generate cross platform, Java-based installers that both encompass and embrace the target operating systems heterogeneity (Windows, Mac OS X, Linux, *BSD, Solaris). IzPack is by no mean rigid and lets you compose your installers the way you want through a wide range of existing features and extension points.
This talk will outline: the IzPack features, its use-cases and positioning against other deployment solutions, the history of the project, from a fun hack made in a student dorm-room to an industry-backed international project thoughts on building a project community, licensing matters, sustaining/scaling a project in the long term and business-model considerations.

SPOTLIGHT IGNITE (10 MINUTES): THE FUTURE OF DEVELOPER TOOLS: FROM STACKOVERF...DevOpsDays Tel Aviv
When writing code there are many common repetitive tasks that we need to write but don't want to invent ourselves, such as CRUD operations, http client etc. There are of course many frameworks and packages that we can use and rely on but we need to learn how to use them. So in most cases for implementing common operations and patterns we find ourselves searching in Google.
With very basic string syntax we search for what we are looking for and usually the search engine will give us back a Stack Overflow solution. In most cases we will copy and paste it (or some similar version of it) to our IDE. This process is time consuming, error prone and distracting, we lose our focus and context every time we leave the IDE to the browser and make decisions on our code that might be risky. However, relying on the knowledge of the developer community is important and very helpful for all of us.
So Instead of searching on the web for solutions, it seems that integrating stack overflow inside our IDE will make developers more efficient and less likely to make mistakes. With the continued growth of technology, prediction tools such as Intellij and AI systems a new line of developer tools emerges such as CoPilot , Kite and TabNine that are going to shape the future of developers. These tools have an AI engine that is able to give code suggestions for whole lines or entire functions right inside the IDE based on simple sentences.
This might sound scary for many of us developers, as it's going to change the way we work but I actually think it's exciting. In my talk I am going to share with you a bit more details about these tools and how they work and why I think all of us should take part in shaping our future.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
