Develop tools and systems that apply ML to real applications on real data and try to deal with attacks and explain the decisions of AI powered decision making. In addition, the seminar will discuss methods to make these tools more efficient and more accessible.

The class provides insights about:

• Multi-modal data fusion, knowledge graphs, modeling context and situation awareness, user profiling, and matching interests with streaming data ( sensors, text, tweets, video, news articles, emails, phone calls), pattern recognition, data mining, intelligent query processing. Machine learning models to connect user's needs with data based on situation and context awareness.
• Privacy-enabling frameworks for situational-aware systems. Representing networks and knowledge graphs using graph databases, graph analytics for enhancing search.
• Machine learning in data cleaning, video data understanding, and data mining and identifying objects and events. Modeling user queries to build knowledge graphs to target data to users. AutoML and self-supervised learning: Deep learning to accelerate the labeling of data and carefully tune hyper-parameters. Learn automatically and learn on unlabeled data to make machine learning accurate and efficient. Labeling and learning with incomplete or limited data.
• Attacks on ML models, training data, and streaming data. Preserving privacy and security by monitoring attacks, mitigating attacks, dealing with changing behavior of adversary, collaborative attacks, predicting attacks, and intent. Deep learning-based Programming Language Processing for Detecting Evasive Cyber-attacks, Trusted Classification under Poisoning attacks using Semantic Factors. Bias and Fairness in ML, what fairness means, causes that introduce unfairness in ML, Data-driven methods that unintentionally encode existing human biases and introduce new ones.
• Defensive methods to protect Deep Neural Networks (DNNs).
• The success DNNs in image-related applications is threatened by their vulnerability to adversarial settings, including trojan and adversarial sample attacks. A detailed explanation of these types of attacks and countering methods are covered.
• Insider threats are considered one of the most serious and difficult problems to solve, given the privileges and information available to insiders to launch different types of attacks. Current security systems can record and analyze sequences from a deluge of log data, potentially becoming a tool to detect insider threats. The issue is that insiders mix the sequence of attack steps with valid actions, reducing the capacity of security systems to discern long sequences and programmatically detect the executed attacks. M Deep learning-based methods are introduced, which overcome the existing limitations and protect against these types of attacks.
• Monitoring and learning of attacks on autonomous systems and cyber attribution.
• Enhancing Cognitive Autonomy through Deep learning. Autonomous systems, explanation of ML, and actions of autonomous activity with humans in the loop.
• Attacks on space system protocols that use moving target defense and utilizing ML to identify intent and devising methods to mitigate.
• Building recommendation systems. Deep learning in trading: Deep learning to track the market and make trading decisions.
• Privacy-preserving predictive modeling in edge networks, privacy issues in ML used in contact tracing.

Class Format

• This is a seminar course. Each class will consist of presentations and discussions. Students will be required to do a class project for the course. A significant portion of the grade will be based on projects and class/research contributions, including paper presentations, contributions to paper reviews, and paper discussions.

Project

• A research class project: Each of you will work on a research project. Group projects are encouraged. The project will be broken down into three assignments: (1) initial research proposal, (2) intermediate report, (3) final report, and presentation.
• Feel free to discuss your ideas with the instructor and propose your own project. The project should have a research component. Project ideas will be outlined in class, but you are responsible for proposing your project. Some background reading is associated with each project. The project proposal (due date Feb 10) should contain the following information:
  • Topic to be addressed and problem definition.
  • State of the art (prior work, what was done and what needs to be done.)
  • The proposed technique to be advanced, developed and implemented/evaluated.
  • How does your work advance the solution to the problem?.
  • Algorithm proposed, Experiments and Data collected, Conclusions/Guidelines.
  Project proposals should be a couple of pages at most. A project status report is due on March 10. The status report should include a description of progress to date and what is expected to be accomplished by the final project presentation day.

Misc

• Class time may be adjusted to accomodate external talks releated to the class.

How papers and proposals are reviewed (example reviews are shown below)

Comments:

This paper proposes VLMS, a novel post-quantum searchable encryption scheme supporting multi-keyword ranked retrieval and result verification. The work is technically sound, well-motivated, and demonstrates a practical efficiency-accuracy trade-off. The manuscript is strong and requires only minor revisions to improve clarity and consistency before publication.

Strengths:

• Novelty: The work offers a clear contribution to the post-quantum searchable encryption landscape.

• Technical Soundness: The proposed scheme effectively addresses complex challenges (multi-keyword ranking, verification) within a post-quantum framework.

• Evaluation: The experimental evaluation is comprehensive, providing convincing evidence of the scheme's practical potential and favorable performance trade-offs.

Recommended Revisions: I recommend the authors address the following minor points:

• Rigor of Security Proof: The derivation of Equation 7 in the security proof is too concise. The authors should expand this section to include the intermediate steps, thereby strengthening the proof's rigor.

• Threat Model Consistency: The threat model is described as "honest-but-curious," but the scheme's inclusion of a verification mechanism suggests it also guards against a malicious server that tampers with results. This apparent contradiction should be reconciled, and the threat model section refined accordingly.

• Clarity of Notation: The manuscript's notation is quite dense. Despite the inclusion of a symbol table, it remains challenging to follow. The authors are encouraged to streamline and standardize the notation throughout the paper to enhance readability.

• Typos and Clarity: The paper contains several typographical errors (e.g., "with an an increasing number..." in the abstract; "Resistence to quantum attack" on p. 12) and minor unclear phrasing. The entire manuscript should be carefully proofread to correct these errors.

https://seedfund.nsf.gov/resources/review/merit-review/

The two merit review criteria are listed below. Both criteria are to be given full consideration during the review and decision-making processes; each criterion is necessary but neither, by itself, is sufficient. Therefore, proposers must fully address both criteria. (Chapter II.D.2.d(i) contains additional information for use by proposers in development of the Project Description section of the proposal.) Reviewers are strongly encouraged to review the criteria, including Chapter II.D.2.d(i), prior to the review of a proposal. When evaluating NSF proposals, reviewers will be asked to consider what the proposers want to do, why they want to do it, how they plan to do it, how they will know if they succeed, and what benefits could accrue if the project is successful. These issues apply both to the technical aspects of the proposal and the way in which the project may make broader contributions. To that end, reviewers will be asked to evaluate all proposals against two criteria:

• Intellectual Merit: The Intellectual Merit criterion encompasses the potential to advance knowledge; and

• Broader Impacts: The Broader Impacts criterion encompasses the potential to benefit society and contribute to the achievement of specific, desired societal outcomes.

The following elements should be considered in the review for both criteria:

• What is the potential for the proposed activity to:

1. Advance knowledge and understanding within its own field or across different fields (Intellectual Merit); and

2. Benefit society or advance desired societal outcomes (Broader Impacts)?

• To what extent do the proposed activities suggest and explore creative, original, or potentially transformative concepts?

• Is the plan for carrying out the proposed activities well-reasoned, well-organized, and based on a sound rationale? Does the plan incorporate a mechanism to assess success?

• How well qualified is the individual, team, or organization to conduct the proposed activities?

• Are there adequate resources available to the PI (either at the home organization or through collaborations) to carry out the proposed activities?

Project deliverables have a firm deadline. Extensions may only be granted in the case of a severe medical or family emergency.

If you become quarantined or isolated at any point in time during the semester, in addition to support from the Protect Purdue Health Center, you will also have access to an Academic Case Manager who can provide you academic support during this time. Your Academic Case Manager can be reached at acmq@purdue.edu and will provide you with general guidelines/resources around communicating with your instructors, be available for academic support, and offer suggestions for how to be successful when learning remotely. Importantly, if you find yourself too sick to progress in the course, notify your academic case manager and notify me via email. We will make arrangements based on your particular situation. The Office of the Dean of Students (odos@purdue.edu) is also available to support you should this situation occur.

The Protect Purdue Plan, which includes the Protect Purdue Pledge, is campus policy and as such all members of the Purdue community must comply with the required health and safety guidelines. Required behaviors in this class include: staying home and contacting the Protect Purdue Health Center (496-INFO) if you feel ill or know you have been exposed to the virus, wearing a mask in classrooms and campus building, at all times (e.g., no eating/drinking in the classroom), disinfecting desk/workspace prior to and after use, maintaining proper social distancing with peers and instructors (including when entering/exiting classrooms), refraining from moving furniture, avoiding shared use of personal items, maintaining robust hygiene (e.g., handwashing, disposal of tissues) prior to, during and after class, and following all safety directions from the instructor. Students who are not engaging in these behaviors (e.g., wearing a mask) will be offered the opportunity to comply. If non-compliance continues, possible results include instructors asking the student to leave class and instructors dismissing the whole class. Students who do not comply with the required health behaviors are violating the University Code of Conduct and will be reported to the Dean of Students Office with sanctions ranging from educational requirements to dismissal from the university. Any student who has substantial reason to believe that another person in a campus room (e.g., classroom) is threatening the safety of others by not complying (e.g., not wearing a mask) may leave the room without consequence. The student is encouraged to report the behavior to and discuss next steps with their instructor. Students also have the option of reporting the behavior to the Office of the Student Rights and Responsibilities. See also Purdue University Bill of Student Rights.
