This document provides an introduction to artificial intelligence and intelligent agents. It discusses key concepts including:
- Agents can be human, robotic, or software entities that perceive their environment and act upon it.
- There are different types of agent programs including simple reflex agents, model-based reflex agents, goal-based agents, and utility-based agents.
- Task environments for agents can have different properties such as being fully or partially observable, deterministic or stochastic, and single-agent or multi-agent.
- Rational agents are designed to perform well according to a defined performance measure in their given environment. Learning agents can improve their performance over time by experiencing examples.

Long Lin at AI Frontiers : AI in GamingAI Frontiers
Games have been leveraging AI since the 1950s, when people built a rules-based AI engine that played tic-tac-toe. With technological advances over the years, AI has become increasingly popular and widely used in the gaming industry. The typical characteristics of games and game development makes them an ideal playground for practicing and implementing AI techniques, especially deep learning and reinforcement learning. Most games are well scoped; it is relatively easy to generate and use the data; and states/actions/rewards are relatively clear. In this talk, I will show a couple of use cases where ML/AI helps in-game development and enhances player experience. Examples include AI agents playing game and services that provide personalized experience to players.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

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).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Artificial Intelligent Agents
1. Introduction to
Artificial Intelligence
DR. MAZHAR ALI
FACULTY OF COMPUTING AND INFORMATION TECHNOLOGY
Intelligent Agents Part-1
Reference Book: Artificial Intelligence: A Modern Approach
2. Agents
• An agent is an entity that perceives and acts
•
• Human agent:
• eyes, ears, and other organs for sensors;
• hands, legs, mouth, and other body parts for actuators
• An artificial agent is anything that can be viewed as perceiving its
environment through sensors and acting upon that environment
through actuators
• Robotic agent:
• cameras and infrared range finders for sensors;
• various motors for actuators
2
5. Simple Terms
Percept
Agent’s perceptual inputs at any given instant
Percept sequence
Complete history of everything that the agent has ever perceived.
5
6. Agent function & program
Agent’s behavior is mathematically described by
Agent function
A function mapping any given percept sequence to an action
Practically it is described by
An agent program
The real implementation
6
8. Program implements the agent
function
Function Reflex-Vacuum-Agent([location,status]) return an
action
If status = Dirty then return Suck
else if location = A then return Right
else if location = B then return left
8
9. Concept of Rationality
Rational agent
One that does the right thing
= every entry in the table for the agent function is correct (rational).
What is correct?
The actions that cause the agent to be most successful
So we need ways to measure success.
9
10. Performance measure
Performance measure
An objective function that determines
How the agent does successfully
E.g., 90% or 30% ?
An agent, based on its percepts
action sequence :
if desirable, it is said to be performing well.
No universal performance measure for all agents
10
11. Omniscience
An omniscient agent
Knows the actual outcome of its actions in
advance
No other possible outcomes
However, impossible in real world
An example
tic-tac-toe
11
12. Learning
Does a rational agent depend on only current percept?
No, the past percept sequence should also be used
This is called learning
After experiencing an episode, the agent
should adjust its behaviors to perform better for the same job next time.
12
13. Autonomy
If an agent just relies on the prior knowledge of its
designer rather than its own percepts then the agent
lacks autonomy
A rational agent should be autonomous- it should
learn what it can to compensate for partial or
incorrect prior knowledge.
E.g., a clock
No input (percepts)
Run only but its own algorithm (prior knowledge)
No learning, no experience, etc.
13
14. Software Agents
Sometimes, the environment may not be the
real world
E.g., flight simulator, video games, Internet
They are all artificial but very complex
environments
Those agents working in these environments are
called
Software agent (softbots)
Because all parts of the agent are software
14
15. Task environments
Task environments are the problems
While the rational agents are the solutions
Specifying the task environment
PEAS description as fully as possible
Performance
Environment
Actuators
Sensors
In designing an agent, the first step must always be to specify the task
environment as fully as possible.
Use automated taxi driver as an example
15
16. Task environments
Environment
A taxi must deal with a variety of roads
Traffic lights, other vehicles, pedestrians, stray
animals, road works, police cars, etc.
Interact with the customer
16
17. Task environments
Actuators (for outputs)
Control over the accelerator, steering, gear
shifting and braking
A display to communicate with the customers
Sensors (for inputs)
Detect other vehicles, road situations
GPS (Global Positioning System) to know where
the taxi is
Many more devices are necessary
17
19. Properties of task environments
Fully observable vs. Partially observable
If an agent’s sensors give it access to the complete state of the environment at
each point in time then the environment is effectively and fully observable
if the sensors detect all aspects
That are relevant to the choice of action
19
20. Properties of task environments
Deterministic vs. stochastic
next state of the environment Completely determined
by the current state and the actions executed by the
agent, then the environment is deterministic, otherwise,
it is Stochastic.
Strategic environment: deterministic except for actions
of other agents
-Cleaner and taxi driver are:
Stochastic because of some unobservable aspects noise or
unknown
20
21. Properties of task environments
Episodic vs. sequential
An episode = agent’s single pair of perception & action
The quality of the agent’s action does not depend on other
episodes
Every episode is independent of each other
Episodic environment is simpler
The agent does not need to think ahead
Sequential
Current action may affect all future decisions
-Ex. Taxi driving and chess.
21
22. Properties of task environments
Static vs. dynamic
A dynamic environment is always changing over
time
E.g., the number of people in the street
While static environment
E.g., the destination
Semidynamic
environment is not changed over time
but the agent’s performance score does
22
23. Properties of task environments
Discrete vs. continuous
If there are a limited number of distinct states,
clearly defined percepts and actions, the
environment is discrete
E.g., Chess game
Continuous: Taxi driving
23
24. Properties of task environments
Single agent VS. multiagent
Playing a crossword puzzle – single agent
Chess playing – two agents
Competitive multiagent environment
Chess playing
Cooperative multiagent environment
Automated taxi driver
Avoiding collision
24
25. Properties of task environments
Known vs. unknown
This distinction refers not to the environment itslef but to the
agent’s (or designer’s) state of knowledge about the
environment.
-In known environment, the outcomes for all actions are
given. ( example: solitaire card games).
- If the environment is unknown, the agent will have to learn
how it works in order to make good decisions.( example:
new video game).
25
28. Introduction to
Artificial Intelligence
DR. MAZHAR ALI
FACULTY OF COMPUTING AND INFORMATION TECHNOLOGY
Artificial Agents Part-II
Reference Book: Artificial Intelligence: A Modern Approach
29. Agent programs
Input for Agent Program
Only the current percept
Input for Agent Function
The entire percept sequence
The agent must remember all of them
Implement the agent program as
A look up table (agent function)
29
30. Agent programs
Despite of huge size, look up table does what we want.
The key challenge of AI
Find out how to write programs that, to the extent possible, produce rational
behavior
From a small amount of code
Rather than a large amount of table entries
E.g., a five-line program of Newton’s Method
V.s. huge tables of square roots, sine, cosine, …
30
32. Simple reflex agents
It uses just condition-action rules
The rules are like the form “if … then …”
efficient but have narrow range of applicability
Because knowledge sometimes cannot be stated explicitly
Work only
if the environment is fully observable
32
35. A Simple Reflex Agent in Nature
percepts
(size, motion)
RULES:
(1) If small moving object,
then activate SNAP
(2) If large moving object,
then activate AVOID and inhibit SNAP
ELSE (not moving) then NOOP
Action: SNAP or AVOID or NOOP
needed for
completeness
35
36. Model-based Reflex Agents
For the world that is partially observable
the agent has to keep track of an internal state
That depends on the percept history
Reflecting some of the unobserved aspects
E.g., driving a car and changing lane
Requiring two types of knowledge
How the world evolves independently of the agent
How the agent’s actions affect the world
36
37. Example Table Agent
With Internal State
Saw an object ahead,
and turned right, and
it’s now clear ahead
Go straight
Saw an object Ahead,
turned right, and object
ahead again
Halt
See no objects ahead Go straight
See an object ahead Turn randomly
IF THEN
37
38. Example Reflex Agent With Internal State:
Wall-Following
Actions: left, right, straight, open-door
Rules:
1. If open(left) & open(right) and open(straight) then
choose randomly between right and left
2. If wall(left) and open(right) and open(straight) then straight
3. If wall(right) and open(left) and open(straight) then straight
4. If wall(right) and open(left) and wall(straight) then left
5. If wall(left) and open(right) and wall(straight) then right
6. If wall(left) and door(right) and wall(straight) then open-door
7. If wall(right) and wall(left) and open(straight) then straight.
8. (Default) Move randomly
start
38
41. Goal-based agents
Current state of the environment is always not enough
The goal is another issue to achieve
Judgment of rationality / correctness
Actions chosen goals, based on
the current state
the current percept
41
42. Goal-based agents
Conclusion
Goal-based agents are less efficient
but more flexible
Agent Different goals different tasks
Search and planning
two other sub-fields in AI
to find out the action sequences to achieve its goal
42
44. Utility-based agents
Goals alone are not enough
to generate high-quality behavior
E.g. meals in Canteen, good or not ?
Many action sequences the goals
some are better and some worse
If goal means success,
then utility means the degree of success (how successful it is)
44
46. Utility-based agents
it is said state A has higher utility
If state A is more preferred than others
Utility is therefore a function
that maps a state onto a real number
the degree of success
46
47. Utility-based agents (3)
Utility has several advantages:
When there are conflicting goals,
Only some of the goals but not all can be achieved
utility describes the appropriate trade-off
When there are several goals
None of them are achieved certainly
utility provides a way for the decision-making
47
48. Learning Agents
After an agent is programmed, can it work immediately?
No, it still need teaching
In AI,
Once an agent is done
We teach it by giving it a set of examples
Test it by using another set of examples
We then say the agent learns
A learning agent
48
49. Learning Agents
Four conceptual components
Learning element
Making improvement
Performance element
Selecting external actions
Critic
Tells the Learning element how well the agent is doing with respect to
fixed performance standard.
(Feedback from user or examples, good or not?)
Problem generator
Suggest actions that will lead to new and informative experiences.
