About

The IEEE 15th International Conference on Pattern Recognition Systems (ICPRS) is an annual international event that follows ICPRS-24, ICPRS-23, ICPRS-22, ICPRS-21, ICPRS-19, ICPRS-18, ICPRS-17 and ICPRS-16, a continuation of the successful Chilean Conference on Pattern Recognition that reached its 6th edition in 2014. In 2025 it is organised by the University Adolfo Ibáñez (Viña del Mar, Chile) and the Chilean Association for Pattern Recognition (ACHiRP, a member of the IAPR), endorsed by the IAPR and the IEEE Chile Section. As per previous years, papers deemed to be of the required standard AND presented at the conference will be published by the IEEE and indexed in IEEE Xplore. Please note that the publishers might reject papers which are too similar to previous publications, even if the work is presented at the conference. All papers need to be submitted via Conftool to be peer-reviewed (double-blind) by an international panel of experts.

There will be prizes (first and runner up) for the best paper overall and for the best student paper (where the first author is a student), that will be invited to submit extended versions for consideration for a Special Section in the Pattern Recognition Letters journal.

The International Conference on Pattern Recognition Systems (ICPRS-25) aims to create an important networking forum in which participants can discuss the present and future of pattern recognition systems.

Its predecessors ICPRS-24, ICPRS-23, ICPRS-22, ICPRS-21, ICPRS-19, ICPRS-18, ICPRS-17, ICPRS-16, CWPR and CCPR, have traditionally been a meeting point of different disciplines (computer science, engineering, mathematics, machine learning, etc.) and an opportunity for a wide range of researchers and practitioners to discuss the many different aspects of the application of pattern recognition technologies.

Travel/Getting there

Customs

If you are not a Chilean citizen, when entering the country the Chilean immigration authorities will give you a tourist card (‘tarjeta de turismo’), an A5-sized white form. Keep it safe and give it to immigration when you leave the country. If you lose it, Chilean police investigations (PDI) allows you to request a copy online (choose ‘Duplicado de tarjeta de turismo’). You can also go to the nearest PDI office.


Please note that Chile has very strict rules about bringing animal or vegetable products into the country. You are strongly advised to declare any such products (even if you carrying an apple!), or you risk heavy fines, using the compulsory declaration form (you might be given one on the plane before arrival, or get a paper form in the airport or fill it electronically)

Airport

The closest airport to Viña del Mar is the Comodoro Arturo Merino Benitez International Airport located in Santiago.

Getting to Viña del Mar

To get to Viña del Mar from the Comodoro Arturo Merino Benitez (SCL) International Airport located in Santiago, you can take either a bus or taxi.

SCL to Viña del Mar by bus
From the Comodoro Arturo Merino Benitez (SCL) International Airport, you need to go to the Pajaritos metro (subway) station. To do this you have the following two options:
  • Getting to the Pajaritos station by bus. These buses are located outside the first floor of the airport. We recommend the bus line Turbus, which goes to Pajaritos from Monday to Sunday between 06:00 and 22:45 hrs., and charges around CLP $2,000 (approximately US$2.00) each way.
  • Getting to Pajaritos by taxi. In this case we recommend Taxi Oficial or the TransVip taxi companies, both of which accept advance reservations. They also have booths within the airport just after baggage scanning. The fare to the Pajaritos station is approx. CLP $10,000–35,000 (approx. US$10–35). Beware: only take official taxis, and avoid drivers who may approach you as you exit the airport.
Once at the Pajaritos subway station, you should go to the bus terminal (located inside the station) and look for the interprovincial bus lines that go to Viña del Mar, if that is where you are staying. We recommend the bus lines Turbus, Pullman Bus or Flixbus. The price of the ticket depends on the day and time, but starts at CLP $5,000 one-way (approx. US$4).

SCL to Viña del Mar by taxi
If you opt for taxi, we recommend that you coordinate in advance on their web sites (see above). Their booths at the airport can be found where you exit the luggage area or in the main lobby. The price from the airport to Viña del Mar is around CLP $100,000–140,000 (approx. USD$100-140). The trip takes about 90 minutes. Beware: only take official taxi, and avoid drivers who may approach you as you exit the airport.

Getting to Universidad Adolfo Ibáñez, campus Viña del Mar

The Viña del Mar campus is located in a hill atop the neighborhood of Los Altos del Sporting Club. It is characterized by its impressive ocean view, and it consists of six buildings, where all the activities of our students and professors take place. To reach the Viña del Mar Campus you can get there by using the free shuttle, by Uber, or by walking. More details follow.

Free university shuttles
The university has free shuttle buses from two points in the city, at specific times throughout the day.

Uber
Another safe and fairly cheap option is to take an Uber to the campus.

Walking
Although it is fairly easy to walk uphill to the campus (approx. 30 mins. walk), we discourage this option as it may be unsafe: the road on the hill is lonely and some cases of thefts and robberies have been reported.

Workshops

The conference will include two hands-on workshops intended for participants interested on learning about:
  • Workshop 1 - Explainable AI (XAI) for Image Analysis with Deep Learning
  • Workshop 2 – Multimodal Learning: Vision + Language

Workshop 1 -Explainable AI (XAI) for Image Analysis with Deep Learning
Description
 This short course introduces participants to the foundations and practical applications of Explainable Artificial Intelligence (XAI) in the context of image analysis with Deep Learning. The course emphasizes the importance of model transparency when applying convolutional neural networks (CNNs) and other deep architectures to image-based tasks. Through a combination of theoretical concepts and guided exercises, participants will explore how to interpret and visualize model decisions using leading XAI methods.


Objectives

  • Understand the need for explainability in computer vision and image-based decision-making.
  • Explore the main categories of XAI methods applicable to deep learning models for images.
  • Gain hands-on experience implementing and comparing XAI techniques in TensorFlow or PyTorch.

Target Audience
Academic community, industry professionals, postgraduate students, and practitioners interested in the development and application of AI models, with a particular focus on deep learning for image analysis and the integration of explainability into real-world scenarios.

Programme

To be announced after paper acceptance.

Registration

For an accepted paper to be presented and published, it needs to be associated to an "Author Full Fee" registration (and not to a Student or an Other registration). If only a student author is attending the conference and presenting their paper, then they need to pay an "Author full fee" (and not the student fee). We have to operate like this to cover conference and publishing costs. Also, if one of the authors registers as "Author Full Fee", additional authors of the same paper who also want to attend the conference only need to pay a lower fee e.g. as Student or Other, as appropriate to their status. Following IAPR policy, each author full fee registration will cover the presentation of up to three papers by the registered person who also needs to be a co-author of those papers. Presentation of additional papers beyond those three, by the same conference delegate will require the payment of an additional full author fee. In all cases there are reductions for members of the sponsoring organisations.

All authors of accepted papers and all other attendees, will need to register using the following link. You will then be redirected to a new webpage. Click on the dropdown menu labeled “Seleccione” to view the list of available options. Scroll to the bottom of the list, where you will find several options related to the conference, listed as “CONGRESO IEEE ICPRS 2025: XXXX”, where XXXX corresponds to the specific type of registration.

Once you select the appropriate option, you will be taken to the next page, where the applicable registration fee will be displayed. Please choose between either RUT (Chilean national ID number) or "Identificador Unico (Tax Id)” (non-Chilean), and complete all required fields, including:

  • RUT / Identificador Unico (Tax Id) => Passport number or any ID
  • First Name / Nombre
  • Last Name / Apellido
  • Email / Correo Electrónico
  • Telephone Number / Teléfono
Next, select your preferred payment method. For international payments, PayPal and Flywire are recommended.

After completing the payment, please send an email to ICPRS@uai.cl with your paper number (if applicable), your payment confirmation and the necessary details for issuing an invoice (e.g. name of organisation, VAT number, etc. as required).
