ChronoSAGE: Diversifying Topic Modeling Chronologically

This document introduces latent semantic indexing (LSI), a technique for information retrieval that overcomes some limitations of the vector space model. LSI represents documents and queries in a semantic space of concepts derived from word co-occurrence patterns in the original text. It uses singular value decomposition to project documents and queries into a concept space of lower dimensionality than the original word space. This addresses problems with synonymy and polysemy. An example shows how LSI can retrieve a document based on conceptual similarity rather than direct word matching. Advantages of LSI include capturing synonymy and polysemy, while disadvantages include increased storage and computational requirements.

Semi-supervised Bibliographic Element Segmentation with Latent Permutations

Tomonari Masada

The document describes a semi-supervised approach to segmenting bibliographic elements in document references using latent permutations. It introduces an approach that models each document as a mixture of topics, and arranges the topic assignments using a latent permutation to capture element order. The approach is evaluated on synthetic datasets, achieving around 82% accuracy on noisy data with random element shuffling.

Tomonari Masada

This document proposes an infinite latent process decomposition (iLPD) model for microarray data. iLPD extends latent process decomposition (LPD) to allow for an infinite number of latent processes. It presents iLPD's generative process and joint distribution. The document also introduces auxiliary variables and provides a collapsed variational Bayesian inference approach for iLPD. This involves deriving a lower bound for the log evidence to evaluate iLPD's efficiency and compare it to LPD. The proposed method improves on past work by treating full posterior distributions over hyperparameters and removing dependencies in computing the variational lower bound.

Poisson factorization

Tomonari Masada

Topic modeling with Poisson factorization is introduced. The generative model assumes words in documents are generated from topics modeled with Poisson distributions. Variational Bayesian inference is used to approximate the posterior. Update equations are derived for the variational parameters ω, representing topic assignments, α, the Dirichlet prior, and γ, the gamma prior over topic distributions. ω is updated proportionally to functions of α and γ. α is updated based on sums of ω. γ is updated based on sums of ω and the prior shape parameter.

A Simple Stochastic Gradient Variational Bayes for the Correlated Topic Model

Tomonari Masada

This document presents a new method for estimating the posterior distribution of the Correlated Topic Model (CTM) using Stochastic Gradient Variational Bayes (SGVB). The CTM is an extension of LDA that models correlations between topics. The proposed method approximates the true posterior of the CTM with a factorial variational distribution and uses SGVB to maximize the evidence lower bound. This allows incorporating randomness into posterior inference for the CTM without requiring explicit inversion of the covariance matrix. Perplexity results on several datasets were comparable to LDA. Future work could explore online learning for topic models using neural networks.

A Simple Stochastic Gradient Variational Bayes for Latent Dirichlet Allocation

Tomonari Masada

This document proposes applying stochastic gradient variational Bayes (SGVB) to latent Dirichlet allocation (LDA) topic modeling to obtain an efficient posterior estimation. SGVB introduces randomness into variational inference for LDA by estimating expectations with Monte Carlo integration and using reparameterization to sample from approximate posterior distributions. Evaluation on several text corpora shows perplexities comparable to existing LDA inference methods, with the potential for faster parallelization using techniques like GPU processing. Future work will explore applying SGVB to other probabilistic document models like correlated topic models.

Tomonari Masada

This document proposes STEPHY, a method for improving LDA topic models by allowing topic distributions to vary over time. STEPHY conducts multistage variational Bayesian inference over LDA models with increasing levels of time dependence, starting with a time-independent model and progressing to models where topic distributions change over timestamps. This multistage approach allows efficient inference by initializing parameters from the previous model. The method is evaluated on several datasets, showing improved perplexity over standard LDA.

This document presents a new method called infinite Latent Process Decomposition (iLPD) for clustering gene expression data from multiple samples. iLPD uses Bayesian nonparametrics to allow the number of clusters to approach infinity, overcoming limitations of previous methods that require specifying the number of clusters. The document describes the iLPD model and inference method, reports on experiments comparing iLPD to the previous LPD method on several gene expression datasets, and discusses potential future work.

Modeling Topical Trends over Continuous Time with Priors

Tomonari Masada

The document presents a Bayesian model called Bayesian Topical Trends (BTOT) to analyze topical trends over continuous time. BTOT applies priors to the beta distributions of Latent Dirichlet Allocation (LDA) to introduce time dependencies. The model is evaluated on a news article dataset and outperforms LDA and other baselines in linking documents that cover the same stories. While BTOT shows improvements, the author notes more research is needed to better balance text and metadata similarities.

A Topic Model for Traffic Speed Data Analysis

Tomonari Masada

This document proposes a topic model called Patchy for analyzing traffic speed data. Patchy models traffic speeds as a mixture of gamma distributions ("patches") in a similar way that latent Dirichlet allocation (LDA) models documents as mixtures of topics. Patchy can assign the same observed speed to different patches depending on context like time of day. When evaluated on classifying weekdays vs weekends, Patchy achieved comparable accuracy to nearest neighbor methods while not requiring timestamp information. The document concludes by discussing modeling timestamps in future work.

Context-dependent Token-wise Variational Autoencoder for Topic Modeling

Tomonari Masada

This document proposes a new variational autoencoder (VAE) approach for topic modeling that addresses the issue of latent variable collapse. The proposed VAE models each word token separately using a context-dependent sampling approach. It minimizes a KL divergence term not considered in previous VAEs for topic modeling. An experiment on four large datasets found the proposed VAE improved over existing VAEs for about half the datasets in terms of perplexity or normalized pairwise mutual information.

Mini-batch Variational Inference for Time-Aware Topic Modeling

Tomonari Masada

This paper proposes a time-aware topic model that uses two vector embeddings: one for latent topics and one for document timestamps. By combining these embeddings, the model extracts time-dependent word probability distributions for each topic. The paper also proposes a mini-batch variational inference for the model that does not require knowing the total number of documents, allowing efficient processing of large datasets. Evaluation on a paper title dataset showed the model could improve perplexity by using timestamps and was comparable to collapsed Gibbs sampling while being more memory efficient.

Document Modeling with Implicit Approximate Posterior Distributions

Tomonari Masada

This document proposes a Bayesian probabilistic model for document modeling that uses an implicit approximate posterior distribution for variational inference. The model generates documents by drawing a noise vector from a standard normal distribution, passing it through a neural network to get parameters for a multinomial distribution, and drawing word counts. Unlike previous models, it uses an implicit distribution approximated by an adversarial training framework to flexibly model the posterior. Evaluation shows the model is comparable to LDA in terms of perplexity.

LDA-Based Scoring of Sequences Generated by RNN for Automatic Tanka Composition

Tomonari Masada

This document proposes a method to score sequences generated by RNN for automatic poetry composition using LDA-based topic modeling. It trains an RNN like GRU or LSTM on a corpus of Japanese tanka poems represented as sequences of character bigrams. It then uses LDA to infer topics in the training corpus and assign words in generated sequences to topics. Sequences containing many words assigned to the same topic receive a higher score, promoting diversity in top-ranked sequences compared to scoring based solely on RNN output probabilities. An experiment on tanka generation found the proposed method selected more varied poems.

A Note on ZINB-VAE

Tomonari Masada

This document presents the equations and process for deriving the evidence lower bound (ELBO) for a zero-inflated negative binomial variational autoencoder (ZINB-VAE) model. It defines the probability distributions for the ZINB-VAE and breaks the log likelihood function into individual terms. It then uses a variational approximation to the intractable posterior distribution to obtain the ELBO that can be optimized. Monte Carlo sampling is used to approximate the expectation with respect to the variational distribution.

A Note on Latent LSTM Allocation

Tomonari Masada

This document summarizes the derivation of an evidence lower bound (ELBO) for latent LSTM allocation, a model that uses an LSTM to determine topic assignments in a topic modeling framework. It expresses the ELBO as terms related to the variational posterior distributions over topics and topics proportions, the generative process of words given topics, and the LSTM's prediction of topic assignments. It also describes how to optimize the ELBO with respect to the variational and LSTM parameters through gradient ascent.

A Note on TopicRNN

Tomonari Masada

TopicRNN is a generative model for documents that: 1. Draws a topic vector from a standard normal distribution and uses it to generate words in a document. 2. Computes a lower bound on the log marginal likelihood of words and stop word indicators. 3. Approximates the expected values in the lower bound using samples from an inference network that models the approximate posterior distribution over topics.

A Simple Stochastic Gradient Variational Bayes for Latent Dirichlet Allocation

Tomonari Masada

This document proposes a new inference method for latent Dirichlet allocation (LDA) based on stochastic gradient variational Bayes (SGVB). The proposed method approximates the true posterior using a logistic normal distribution, rather than the Dirichlet distribution used in standard variational Bayes for LDA. Through experiments, the proposed method achieved better predictive performance than standard variational Bayes and collapsed Gibbs sampling on many datasets, demonstrating the effectiveness of SGVB for devising new variational inferences.

Tomonari Masada

This document summarizes a hierarchical topic modeling approach for analyzing traffic speed data. The model treats each day's data as a mixture of different speed distributions. It extends latent Dirichlet allocation to model speeds as continuous gamma distributions rather than discrete words. The model further incorporates metadata on time of day and sensor location to make topic probabilities dependent on context. Model parameters are estimated using variational Bayesian inference, and the model achieves better performance than alternatives by capturing similarity between observations based on timing and location.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL

ijaia

As digital technology becomes more deeply embedded in power systems, protecting the communication networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3) represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities. Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network (CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to train and test our model. The results of our experiments show that our CNN-LSTM method is much better at finding smart grid intrusions than other deep learning algorithms used for classification. In addition, our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection accuracy rate of 99.50%.

Applications of artificial Intelligence in Mechanical Engineering.pdf

Atif Razi

Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI. AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

Accident detection system project report.pdf

Kamal Acharya

The Rapid growth of technology and infrastructure has made our lives easier. The advent of technology has also increased the traffic hazards and the road accidents take place frequently which causes huge loss of life and property because of the poor emergency facilities. Many lives could have been saved if emergency service could get accident information and reach in time. Our project will provide an optimum solution to this draw back. A piezo electric sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With signals from a piezo electric sensor, a severe accident can be recognized. According to this project when a vehicle meets with an accident immediately piezo electric sensor will detect the signal or if a car rolls over. Then with the help of GSM module and GPS module, the location will be sent to the emergency contact. Then after conforming the location necessary action will be taken. If the person meets with a small accident or if there is no serious threat to anyone’s life, then the alert message can be terminated by the driver by a switch provided in order to avoid wasting the valuable time of the medical rescue team.
