[ICCV 21] Influence-Balanced Loss for Imbalanced Visual ClassificationSeulki Park
This document proposes a new influence-balanced loss function for training deep neural networks on imbalanced visual classification tasks. It discovers that existing loss functions can lead to overfitting on majority classes. The new loss measures each sample's influence on the decision boundary and downweights influential majority samples to reduce overfitting. Experiments on long-tailed and real-world imbalanced datasets demonstrate state-of-the-art accuracy, especially for minority classes. The method is easy to implement and can improve generalization on imbalanced data.
Learning deep representation from coarse to fine for face alignmentZhiwen Shao
This document proposes a coarse-to-fine training algorithm to improve the accuracy of facial landmark detection using a single deep convolutional network. The algorithm first trains the network to detect a subset of key landmarks to extract intrinsic facial structure, then fine-tunes it by adjusting the weight of detecting this principal subset to better locate all landmarks. Evaluation on three benchmarks shows the coarse-to-fine training approach achieves state-of-the-art mean error rates for face alignment compared to other methods.
Using networks to explore, quantify, and summarize phylogenetic tree spacejembrown
The document describes using networks to analyze and summarize sets of phylogenetic trees. It discusses constructing networks where trees are connected based on their similarities, and calculating covariances between bipartitions across trees. These networks can be used to detect distinct phylogenetic signals, assess model fit by comparing empirical and simulated networks, and summarize tree sets through techniques like consensus trees and community detection. Initial results on simulated data show the network approach can recover known distinct signals and detect strong conflicts. Software called TreeScaper is introduced for constructing these networks.

This document discusses local bias in parametric estimation models and its impact on model performance. It defines local bias as the deviation between parameters calibrated from local data versus general model defaults. An analysis of a software cost estimation model finds local bias varies between data groups and is positively correlated with decreased model accuracy and increased uncertainty, as measured by mean and variance of magnitude of relative error. The implications are that local bias should be identified and addressed to improve model evolution and balance accuracy versus stability.
Combining Committee-Based Semi-supervised and Active Learning and Its Applica...Mohamed Farouk
Semi-supervised learning reduces the cost of labeling the
training data of a supervised learning algorithm through using unlabeled
data together with labeled data to improve the performance. Co-Training
is a popular semi-supervised learning algorithm, that requires multiple redundant
and independent sets of features (views). In many real-world application
domains, this requirement can not be satisfied. In this paper, a
single-view variant of Co-Training, CoBC (Co-Training by Committee),
is proposed, which requires an ensemble of diverse classifiers instead of
the redundant and independent views. Then we introduce two new learning
algorithms, QBC-then-CoBC and QBC-with-CoBC, which combines
the merits of committee-based semi-supervised learning and committeebased
active learning. An empirical study on handwritten digit recognition
is conducted where the random subspace method (RSM) is used to
create ensembles of diverse C4.5 decision trees. Experiments show that
these two combinations outperform the other non committee-based ones.

Every experiment yields multiple data types, each requiring unique analyses and controls due to the sub-micron nature of an innovative organic light-emitting diode (OLED). Three specific data methods will be discussed. First, the premise of the study centers on a six-factor definitive screening design that was built utilizing new features incorporated in JMP 13 for improved power and signal detection. Multiple responses were modeled with a defect model generated via use of the Profiler and Simulation studies. Second, devices are continually monitored for radiance loss in an accelerated fade test. Frequently, devices are removed from the test prior to reaching their failure point. Predicted failure times can be estimated by utilizing a custom nonlinear model in either the Reliability Degradation or Nonlinear Model platforms. Estimated failure times were then incorporated into traditional parametric survival techniques, as well as new features in the Generalized Regression platform. Lastly, radiance data is collected across the visual spectrum, resulting in approximately 100 correlated responses.

A comparative review of various approaches for feature extraction in Face rec...Vishnupriya T H
This document provides an overview of various approaches for feature extraction in face recognition. It discusses common feature extraction algorithms such as PCA, DCT, LDA, and ICA. PCA is aimed at data compression while ensuring no information loss. DCT transforms images from spatial to frequency domains. LDA maximizes between-class variations and minimizes within-class variations. ICA determines statistically independent variables and minimizes higher-order dependencies. The document reviews several papers comparing the performance of these algorithms individually and in combination for face recognition applications.
Representational Continuity for Unsupervised Continual LearningMLAI2
Continual learning (CL) aims to learn a sequence of tasks without forgetting the previously acquired knowledge. However, recent CL advances are restricted to supervised continual learning (SCL) scenarios. Consequently, they are not scalable to real-world applications where the data distribution is often biased and unannotated. In this work, we focus on unsupervised continual learning (UCL), where we learn the feature representations on an unlabelled sequence of tasks and show that reliance on annotated data is not necessary for continual learning. We conduct a systematic study analyzing the learned feature representations and show that unsupervised visual representations are surprisingly more robust to catastrophic forgetting, consistently achieve better performance, and generalize better to out-of-distribution tasks than SCL. Furthermore, we find that UCL achieves a smoother loss landscape through qualitative analysis of the learned representations and learns meaningful feature representations. Additionally, we propose Lifelong Unsupervised Mixup (Lump), a simple yet effective technique that interpolates between the current task and previous tasks' instances to alleviate catastrophic forgetting for unsupervised representations.
Learning similarity functions from qualitative feedbackroywwcheng
The performance of a case-based reasoning system often depends on the suitability of an underlying similarity (distance) measure,
and specifying such a measure by hand can be very difficult. In this paper, we therefore develop a machine learning approach to similarity assessment. More precisely, we propose a method that learns how to combine given local similarity measures into a global one. As training information,
the method merely assumes qualitative feedback in the form of similarity comparisons, revealing which of two candidate cases is more similar to
a reference case. Experimental results, focusing on the ranking performance
of this approach, are very promising and show that good models can be obtained with a reasonable amount of training information. See more at www.chengweiwei.com

Opposition-based learning (OBL) and cooperative

In this work, we propose a novel framework for hybridizing these two techniques, and investigate the performance of simple implementations of this new framework using the most recent LSGO benchmarking test suite. The obtained results verify the effectiveness of our proposed OBL-CC framework. Moreover, some advanced statistical analyses reveal that the proposed hybridization significantly outperforms its component methods in terms of the quality of finally obtained solutions.

Yen-Yu Lin presents research on video synthesis through frame interpolation. His lab uses deep learning models like DVF to predict intermediate frames between two consecutive frames. However, existing methods produce artifacts or over-smoothed results. The proposed approach uses a two-stage training procedure with cycle consistency loss to address this. It first pre-trains DVF, then fine-tunes with cycle loss to make the model robust to lack of data and produce higher quality frames. Experimental results show the approach outperforms state-of-the-art methods on standard datasets.

Neural information retrieval and conversational question answering techniques are being used to build intelligent systems like conversational knowledge bases and ticketing systems. However, operationalizing deep learning models presents challenges regarding data needs, online usage, and interpretability. Combining neural models with linear models and term frequency-based approaches can help address these challenges, enabling reliable user experiences through one-shot learning and an editable knowledge base. User behavior like skimming content also requires interfaces that manage expectations and provide hybrid experiences.

Gamify it until you make it Improving Agile Development and Operations with ...Ben Linders
So many challenges, so little time. While we’re busy developing software and keeping it operational, we also need to sharpen the saw, but how? Gamification can be a way to look at how you’re doing and find out where to improve. It’s a great way to have everyone involved and get the best out of people.
In this presentation, Ben Linders will show how playing games with the DevOps coaching cards can help to explore your current development and deployment (DevOps) practices and decide as a team what to improve or experiment with.
The games that we play are based on an engagement model. Instead of imposing change, the games enable people to pull in ideas for change and apply those in a way that best suits their collective needs.
By playing games, you can learn from each other. Teams can use games, exercises, and coaching cards to discuss values, principles, and practices, and share their experiences and learnings.
Different game formats can be used to share experiences on DevOps principles and practices and explore how they can be applied effectively. This presentation provides an overview of playing formats and will inspire you to come up with your own formats.

1.) Introduction
Our Movement is not new; it is the same as it was for Freedom, Justice, and Equality since we were labeled as slaves. However, this movement at its core must entail economics.
2.) Historical Context
This is the same movement because none of the previous movements, such as boycotts, were ever completed. For some, maybe, but for the most part, it’s just a place to keep your stable until you’re ready to assimilate them into your system. The rest of the crabs are left in the world’s worst parts, begging for scraps.
3.) Economic Empowerment
Our Movement aims to show that it is indeed possible for the less fortunate to establish their economic system. Everyone else – Caucasian, Asian, Mexican, Israeli, Jews, etc. – has their systems, and they all set up and usurp money from the less fortunate. So, the less fortunate buy from every one of them, yet none of them buy from the less fortunate. Moreover, the less fortunate really don’t have anything to sell.
4.) Collaboration with Organizations
Our Movement will demonstrate how organizations such as the National Association for the Advancement of Colored People, National Urban League, Black Lives Matter, and others can assist in creating a much more indestructible Black Wall Street.
5.) Vision for the Future
Our Movement will not settle for less than those who came before us and stopped before the rights were equal. The economy, jobs, healthcare, education, housing, incarceration – everything is unfair, and what isn’t is rigged for the less fortunate to fail, as evidenced in society.
6.) Call to Action
Our movement has started and implemented everything needed for the advancement of the economic system. There are positions for only those who understand the importance of this movement, as failure to address it will continue the degradation of the people deemed less fortunate.
No, this isn’t Noah’s Ark, nor am I a Prophet. I’m just a man who wrote a couple of books, created a magnificent website: http://www.thearkproject.llc, and who truly hopes to try and initiate a truly sustainable economic system for deprived people. We may not all have the same beliefs, but if our methods are tried, tested, and proven, we can come together and help others. My website: http://www.thearkproject.llc is very informative and considerably controversial. Please check it out, and if you are afraid, leave immediately; it’s no place for cowards. The last Prophet said: “Whoever among you sees an evil action, then let him change it with his hand [by taking action]; if he cannot, then with his tongue [by speaking out]; and if he cannot, then, with his heart – and that is the weakest of faith.” [Sahih Muslim] If we all, or even some of us, did this, there would be significant change. We are able to witness it on small and grand scales, for example, from climate control to business partnerships. I encourage, invite, and challenge you all to support me by visiting my website.
Why Psychological Safety Matters for Software Teams - ACE 2024 - Ben Linders.pdfBen Linders
Psychological safety in teams is important; team members must feel safe and able to communicate and collaborate effectively to deliver value. It’s also necessary to build long-lasting teams since things will happen and relationships will be strained.
But, how safe is a team? How can we determine if there are any factors that make the team unsafe or have an impact on the team’s culture?
In this mini-workshop, we’ll play games for psychological safety and team culture utilizing a deck of coaching cards, The Psychological Safety Cards. We will learn how to use gamification to gain a better understanding of what’s going on in teams. Individuals share what they have learned from working in teams, what has impacted the team’s safety and culture, and what has led to positive change.
Different game formats will be played in groups in parallel. Examples are an ice-breaker to get people talking about psychological safety, a constellation where people take positions about aspects of psychological safety in their team or organization, and collaborative card games where people work together to create an environment that fosters psychological safety.

15. Conclusion
Coarse-to-fine training algorithm
Our network directly predicts the coordinates of
landmarks using single network without any other
additional operations
The training algorithm can also be applied to
other problems using deep convolutional network
Good afternoon, everyone. Today I introduce my recent work about face alignment using deep convolutional network.
Next, I will introduce my approach in detail.
dozens of
I find that there are a few key landmarks which can coarsely determine face shape including brow corners, eye corners, nose tip, mouth corners and chin tip.
Because different face alignment datasets have different annotation of landmarks, so I fix the location of backbone set
eye centers are also key points, but I don’t choose them because many face alignment datasets such as Helen and 300-W don’t contain eye center landmarks.
Train a deep convolutional network. So I define this loss function. E consists of two items
E sub b
Since the approach is evaluated based on alignment error measured by the distances between estimated landmarks and ground truths normalized with the inter-pupil distance, we use normalized Euclidean distance
In this way, during training, I can directly know the performance of my network from the loss value.
F hat sub b
I propose a coarse-to-fine training algorithm
Firstly control parameter lambda equals lambda sub 0
and is decreased gradually to 0.5.
for each circulation, using current lambda value,
the network is trained until convergence and the network parameters theta is updated.
is very close to 1 but isn’t equal to 1
If we choose lambda sub 0 to be 1, then subsequent search process will not be smooth.
It’s clearly that trained model is optimized stage by stage and the prediction of landmarks location using finally learned model theta sup star is very accurate
Therefore, different from other coarse-to-fine methods,
Although the mean error of CFT tested on
Helen and 300-W is slightly bigger than CFSS and TCDCN,
CFT performs better on challenging COFW whose faces are
taken with severe occlusion. Specifically, CFT produces a significant error reduction of 21.37% on the challenging COFW in comparison to the state-of-the-art TCDCN
