K-MEDOIDS CLUSTERING USING PARTITIONING AROUND MEDOIDS FOR PERFORMING FACE R...ijscmc
Face recognition is one of the most unobtrusive biometric techniques that can be used for access control as well as surveillance purposes. Various methods for implementing face recognition have been proposed with varying degrees of performance in different scenarios. The most common issue with effective facial biometric systems is high susceptibility of variations in the face owing to different factors like changes in pose, varying illumination, different expression, presence of outliers, noise etc. This paper explores a novel technique for face recognition by performing classification of the face images using unsupervised learning approach through K-Medoids clustering. Partitioning Around Medoids algorithm (PAM) has been used for performing K-Medoids clustering of the data. The results are suggestive of increased robustness to noise and outliers in comparison to other clustering methods. Therefore the technique can also be used to increase the overall robustness of a face recognition system and thereby increase its invariance and make it a reliably usable biometric modality

안녕하세요 딥러닝 논문읽기 모임 입니다.
오늘 소개 드릴 논문은 2021년 ICLR 에 억셉된 NBDT : Neural-backed Decision Tree 라는 논문 입니다
초록 :
Machine learning applications such as finance and medicine demand accurate and justifiable predictions, barring most deep learning methods from use. In response, previous work combines decision trees with deep learning, yielding models that (1) sacrifice interpretability for accuracy or (2) sacrifice accuracy for interpretability. We forgo this dilemma by jointly improving accuracy and interpretability using Neural-Backed Decision Trees (NBDTs). NBDTs replace a neural network's final linear layer with a differentiable sequence of decisions and a surrogate loss. This forces the model to learn high-level concepts and lessens reliance on highly-uncertain decisions, yielding (1) accuracy: NBDTs match or outperform modern neural networks on CIFAR, ImageNet and better generalize to unseen classes by up to 16%. Furthermore, our surrogate loss improves the original model's accuracy by up to 2%. NBDTs also afford (2) interpretability: improving human trustby clearly identifying model mistakes and assisting in dataset debugging. Code and pretrained NBDTs are at this https URL.

This document discusses decision trees and entropy. It begins by providing examples of binary and numeric decision trees used for classification. It then describes characteristics of decision trees such as nodes, edges, and paths. Decision trees are used for classification by organizing attributes, values, and outcomes. The document explains how to build decision trees using a top-down approach and discusses splitting nodes based on attribute type. It introduces the concept of entropy from information theory and how it can measure the uncertainty in data for classification. Entropy is the minimum number of questions needed to identify an unknown value.
This document discusses anomaly detection techniques for intrusion detection systems. It begins by defining anomalies and explaining the principles of anomaly detection models. It then describes some key challenges in anomaly detection and different types of outputs it can provide. The document proceeds to classify anomaly detection techniques into statistical, machine learning and data mining based methods. As examples, it examines several case studies of early statistical anomaly detection systems like Haystack and IDES.
We all know how to create ML models, but the path to turning them into a highly scalable easy to use system by users is not always clear. What happens when you need to run thousands of them, on many different datasets, simultaneously and at a huge scale? AND, do it reliably so you can sleep well at night!!
To achieve exactly that, we’ve decided to go down the serverless route and build an anomaly detection system on top of it. We’ll go over the pros and cons of building such a system using serverless and when such an approach could work for you.
Our SpotLight anomaly detection system is capable of easily reusing ML models, and scale to run millions of time series simultaneously with ease. Our system eliminates manual work and allows our end users with no scientific background to set anomalies to detect in a plug and play way and get alerts in no time.
In this talk, we’ll walk you through the architecture and share useful ideas you can adopt and implement in your own projects.
This document discusses anomaly detection techniques. It begins with an introduction to anomaly detection and its applications in areas like intrusion detection, fraud detection, and healthcare. It then discusses the use of anomaly detection in AIOps and with graph databases. The document categorizes anomalies as point, contextual, or collective and describes methods for identifying outliers like extreme value analysis. It also discusses techniques for anomaly detection in time series data, including using recurrent neural networks, historical analysis with DBSCAN clustering, and time shift detection using cosine similarity. The document compares pros and cons of time shift detection and DBSCAN for anomaly detection.
Machine learning models are trained on past data with known outcomes to predict unknown future outcomes. The document compares several machine learning algorithms on a medical dataset to predict kidney disease:
- ZeroR classified 28.2% correctly by always predicting stage 3 disease.
- Naive Bayes classified 56.6% correctly using attribute probabilities.
- OneR classified 80.2% correctly with a single rule based on serum creatinine levels.
- J4.5 decision tree classified the highest at 88.4% correctly by recursively splitting data into subgroups based on attribute information gains.
This document discusses anomaly detection using deep auto-encoders. It begins by defining outliers and anomalies, and describes challenges with traditional machine learning techniques for anomaly detection. It then introduces hierarchical feature learning using deep neural networks, specifically using auto-encoders to learn the structure of normal data and detect anomalies based on reconstruction error. Examples of applying this for ECG pulse detection and MNIST digit recognition are provided.

Artificial intelligence and knowledge representationSajan Sahu
The document discusses artificial intelligence and knowledge representation. It describes how computers can be made intelligent through speed of computation, filtering responses, using algorithms and neural networks. It also discusses knowledge representation techniques in AI like propositional logic, semantic networks, frames, predicate logic and nonmonotonic reasoning. The document provides examples and applications of AI like pattern recognition, robotics and natural language processing. It also discusses some fundamental problems of AI.
The document discusses machine learning techniques for analyzing big data. It outlines three tenants of success: prediction, optimization, and automation. Various machine learning models are examined, including linear models, decision trees, neural networks, and clustering. Implementing machine learning algorithms in Hadoop distributed environments is also discussed. Optimization techniques like evolutionary algorithms are presented. Regularly adapting models with updated data is recommended to keep analyses current.
This document describes the random forest algorithm for classification. Random forest creates many decision trees on random subsets of the training data and attributes. Each tree votes for a class, and the class with the most votes across all trees is the random forest prediction. The document outlines the steps to build a random forest: 1) bootstrap samples of data to create training sets, 2) select random subsets of attributes at each node, 3) grow each tree, 4) aggregate trees by majority vote. An example applies random forest to predict if a person will buy a computer based on age, income, student status, and credit rating.
1. Machine learning is a set of techniques that use data to build models that can make predictions without being explicitly programmed.
2. There are two main types of machine learning: supervised learning, where the model is trained on labeled examples, and unsupervised learning, where the model finds patterns in unlabeled data.
3. Common machine learning algorithms include linear regression, logistic regression, decision trees, support vector machines, naive Bayes, k-nearest neighbors, k-means clustering, and random forests. These can be used for regression, classification, clustering, and dimensionality reduction.
Using ATTACK to Create Cyber DBTS for Nuclear Power PlantsMITRE - ATT&CKcon
From MITRE ATT&CKcon Power Hour December 2020
By Jacob Benjamin, Principal Industrial Consultant Dragos, INL, & University of Idaho
Design Basis Threat (DBT) is concept introduced by the Nuclear Regulatory Commission (NRC). It is a profile of the type, composition, and capabilities of an adversary. DBT is the key input nuclear power plants use for the design of systems against acts of radiological sabotage and theft of special nuclear material. The NRC expects its licensees, nuclear power plants, to demonstrate that they can defend against the DBT. Currently, cyber is included in DBTs simply as a prescribed list of IT centric security controls. Using MITRE’s ATT&CK framework, Cyber DBTs can be created that are specific to the facility, its material, or adversary activities.

Seminario Almacenamiento Datos Hoy - 13/12/10CAESCG.org
El documento trata sobre el almacenamiento de datos ambientales. Explica que los científicos generan grandes cantidades de datos de campo y de laboratorio, incluyendo datos espaciales. Estos datos se suelen guardar de forma desorganizada en papel o de manera digital, dificultando su comparación y colaboración. Lo mejor es usar una base de datos geográfica que siga estándares, permitiendo compartir y analizar los datos de una forma organizada.
Este documento describe los tres principales tipos de aprendizaje artificial: 1) aprendizaje supervisado, que utiliza datos etiquetados para predecir valores objetivo; 2) aprendizaje no supervisado, que identifica patrones en datos no etiquetados; y 3) aprendizaje por refuerzo, donde un algoritmo aprende a través de recompensas y castigos de su interacción con el entorno. También describe tres tipos de aprendizaje profundo: redes neuronales convolucionales para procesamiento de imágenes, redes recurrentes para aná

ACERTIJO DESCIFRANDO CÓDIGO DEL CANDADO DE LA TORRE EIFFEL EN PARÍS. Por JAVI...JAVIER SOLIS NOYOLA
El Mtro. JAVIER SOLIS NOYOLA crea y desarrolla el “DESCIFRANDO CÓDIGO DEL CANDADO DE LA TORRE EIFFEL EN PARIS”. Esta actividad de aprendizaje propone el reto de descubrir el la secuencia números para abrir un candado, el cual destaca la percepción geométrica y conceptual. La intención de esta actividad de aprendizaje lúdico es, promover los pensamientos lógico (convergente) y creativo (divergente o lateral), mediante modelos mentales de: atención, memoria, imaginación, percepción (Geométrica y conceptual), perspicacia, inferencia y viso-espacialidad. Didácticamente, ésta actividad de aprendizaje es transversal, y que integra áreas del conocimiento: matemático, Lenguaje, artístico y las neurociencias. Acertijo dedicado a los Juegos Olímpicos de París 2024.

7. En 1959, el científico de la IBM
Arthur Samuel escribió un
programa para jugar damas, para
mejorarlo hizo que el programa
jugara consigo mismo miles de
veces, el programa era capaz de
mejorar su rendimiento a través
de la experiencia, el programa
aprendió y nació el Machine
Learning.

13. La ciencia de datos (Data Science) es la ciencia
computacional de la extracción de conocimientos
significativos a partir de datos brutos y luego la comunicación
efectiva de esos conocimientos para generar valor. (Pierson,
2017)
18. El aprendizaje automático o
Machine Learning es un método
científico que nos permite usar
los ordenadores y otros
dispositivos con capacidad
computacional para que
aprendan a extraer los patrones
y relaciones que hay en nuestros
datos por sí solos. Esos patrones
se pueden usar luego para
predecir comportamientos y en
la toma de decisiones.
19. El Aprendizaje Automático es un campo en la
Inteligencia Artificial, donde las máquinas pueden
"aprender" de sí mismas, sin ser explícitamente
programadas por los seres humanos. Analizando datos
pasados llamados "datos de entrenamiento", el modelo
de Aprendizaje Automático forma patrones y usa estos
patrones para aprender y hacer predicciones futuras.
20. "Se dice que un programa de computadora
aprende de la experiencia E con respecto a alguna
clase de tareas T y la medida de rendimiento P, si
su rendimiento en tareas en T, medido por P,
mejora con la experiencia E. “
Mitchell, 1997

27. Aprendiendo un modelo, de datos etiquetados.
Datos de Entrenamiento: “ejemplos” x con “etiquetas” y.
(x1, y1), . . . , (xn, yn) / xi ∈ Rd
Clasificación: y es discreta.Para simplificar, y ∈ {−1, +1}
f : Rd −→ {−1, +1} f es llamada un clasificador binario.
Ejemplo: Aprobación de créditos si/no, spam/ham,
banana/naranja.
33. Datos de Entrenamiento:“ejemplos” x con “etiquetas” y.
(x1, y1), . . . , (xn, yn) / xi ∈ Rd
Regresión: y es un valor real, y ∈ R
f : Rd → R f es llamado un regresor.
Ejemplo: cantidad de crédito, peso de una fruta.
39. Aprendiendo un modelo, de datos no etiquetados.
Datos de Entrenamiento: “ejemplos” x.
x1, . . . , xn, xi ∈X ⊂ Rn
Clustering/segmentation:
f : Rd −→ {C1, . . . Ck} (Conjunto de clusters).
Ejemplo: Encontrar clusters en la población, frutas, especies.
