R is a widely used programming language and software environment for statistical analysis and graphics. It was first created in 1993 at the University of Auckland as an implementation of the S language. R compiles and runs on Windows, Mac, and UNIX systems and includes packages for text mining, such as tm and SnowballC, which are used to preprocess text through steps like lowering case, removing stopwords and numbers, and stemming words. It also supports creating word clouds and sentiment analysis visualizations.

Whenever you make a list of anything – list of groceries to buy, books to borrow from the library, list of classmates, list of relatives or friends, list of phone numbers and so o – you are actually creating a database.
An example of a business manual database may consist of written records on a paper and stored in a filing cabinet. The documents usually organized in chronological order, alphabetical order and so on, for easier access, retrieval and use.
Computer database are those data or information stored in the computer. To arrange and organize records, computer databases rely on database software
Microsoft Access is an example of database software.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

5. R - Data Types
Primitive (or atomic) data types in R are:
• Numeric (integer, double, complex)
• Character
• Logical
• Function
6. Text Mining with R
R is an open source language and environment for statistical computing and
graphics. It includes packages like tm, SnowballC, ggplot2 and wordcloud, which

9. Reading SQLite data in R
Docs <- Corpus(docs,VectorSource(docs$comments))
# Get all the emails sent by Hillary
Comm <- read.csv(“comments.csv”, header = TRUE)
emailRaw <- paste(emailHillary$EmailBody, collapse=" // ")
10. Cleaning Text in R
Install.packages(“tm”)
Install.packages(“NLP”)
Load text mining package - library(“tm”)
docs <- Corpus(VerctorSum(emailRaw)) – Corpus it is a collection of text
documents
11. Processing text in R
docs <- tm_map(docs, content_transformer(tolower)) – It makes all the words to
lower cases.
docs <- tm_map(docs, removeNumbers) - It removes numbers
docs <- tm_map(docs, removeWords, stopWords(“english”)) – It removes stop
words like the, is, of
docs <- tm_map(docs, removePunctuation) – It removes Punctuation
docs <- tm_map(docs, stripWhiteSpace) – It removes extra White Spaces
12. SnowballC to Stem Text
#Text stemming (reduces words to their root form)
library("SnowballC")
docs <- tm_map(docs, stemDocument)
# Remove additional stopwords
docs <- tm_map(docs, removeWords, c("clintonemailcom", "stategov", "hrod"))
13. SnowballC to Stem Text
dtm <- TermDocumentMatrix(docs)
m <- as.matrix(dtm)
v <- sort(rowSums(m),decreasing=TRUE)
d <- data.frame(word = names(v),freq=v)
head(d, 10)
