June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Data Visualization using different python libraries.pptx
1. DATA VISUALIZATION USING DIFFERENT
PYTHON LIBRARIES (E.G., PANDAS,
NUMPY, MATPLOTLIB)
TEHMIMA ISMAIL
0000412064
MSCS-II
2. WHAT IS DATA VISUALIZATION?
• Introduction to Data Visualization
• Definition: "Field in data analysis, visually represents data."
• Purpose: "Effectively communicates inferences through graphics."
• Benefit: "Provides a quick visual summary of data."
• Tools: "Utilizes pictures, maps, and graphs."
• Advantage: "Easier processing and understanding for the human mind."
• Application: "Applicable to both small and large data sets."
• Challenge: "Impossible manual processing for large data sets."
3. DATA VISUALIZATION IN PYTHON
• Python offers several plotting libraries, namely Matplotlib, Seaborn and
many other such data visualization packages with different features for
creating informative, customized, and appealing plots to present data in the
most simple and effective way.
4. MATPLOTLIB AND SEABORN
• Matplotlib and Seaborn are python libraries that are used for data
visualization.
• They have inbuilt modules for plotting different graphs.
• Matplotlib is used to embed graphs into applications.
• Seaborn is primarily used for statistical graphs.
5. LINE CHARTS
• A Line chart is a graph that represents information as a series of data points connected by a
straight line.
• In line charts, each data point or marker is plotted and connected with a line or curve.
Let's consider the apple yield (tons per hectare) in Kanto. Let's plot a line graph using this data
and see how the yield of apples changes over time. We start by importing Matplotlib and
Seaborn.
7. To better understand the graph and its purpose, we can add the x-axis values
too.
8. • Let's add labels to the axes so that we can show what each axis represents.
9. .
• To plot multiple datasets on the same graph, just use the plt.plot function
once for each dataset. Let's use this to compare the yields of apples vs.
oranges on the same graph.
10. We can add a legend which tells us what each line in our graph means. To
understand what we are plotting, we can add a title to our graph.
11. To show each data point on our graph, we can highlight them with markers
using the marker argument. Many different marker shapes like a circle, cross,
square, diamond, etc. are provided by Matplotlib.
12. You can use the plt.figure function to change the size of the figure.
13. USING SEABORN
• An easy way to make your charts look beautiful is to use some default styles from the
Seaborn library. These can be applied globally using the sns.set_style function.
14. • We can also use the darkgrid option to change the background color to a
darker shade
15. BAR GRAPHS
• Categorical Data Representation:
• Utilize bar graphs for effective representation.
• Y-axis: Represents values; X-axis: Represents categories.
• Axis Interpretation:
• Y-axis reflects numerical data values.
• X-axis denotes categorical data labels.
• Data-Category Relationship:
• Bars visually linked to specific categories.
• Offers clear representation of data distribution.
• Effective Communication:
• Facilitates easy communication of categorical data.
• Provides quick understanding.
• Flexibility for Categorical Data:
• Applicable to various types of categorical data.
• Enables easy comparison between different categories.
17. WE CAN ALSO STACK BARS ON TOP OF EACH OTHER. LET'S
PLOT THE DATA FOR APPLES AND ORANGES
18. PLOTTING AVERAGES OF EACH BAR
• We can draw a bar chart to visualize how the average bill amount varies across different days of the
week. We can do this by computing the day-wise averages and then using plt.bar. The Seaborn library
also provides a barplot function that can automatically compute averages.
19. PLOTTING MULTIPLE BAR GRAPHS
• If you want to compare bar plots side-by-side, you can use the hue argument. The comparison will be
done based on the third feature specified in this argument.
21. HISTOGRAMS
Histogram Overview:
• Utilizes bars to represent data variation across a range.
• Y-axis indicates data frequency, while the X-axis shows value ranges.
• Bars represent data quantities within specific value ranges.
22. IRIS DATASET
• Let's again use the ‘Iris’ data which contains information about flowers to plot histograms.
25. CHANGING NUMBER AND SIZE OF BINS
• We can change the number and size of bins using numpy too.
26. BINS OF UNEQUAL SIZE
• We can create bins of unequal size too.
27. MULTIPLE HISTOGRAMS
• Similar to line charts, we can draw multiple histograms in a single chart. We can reduce each
histogram's opacity so that one histogram's bars don't hide the others'. Let's draw separate histograms
for each species of flowers.
28. STACKING HISTOGRAMS
• Multiple histograms can be stacked on top of one another by setting the stacked parameter to True.

LSTM
• Tesla Stock Price, S&P 500 stock data, AMZN, DPZ, BTC, NTFX adjusted
May 2013-May2019 +1
Data Project - Stock Market Analysis
30. TIME SERIES DATA
• Time Series data is a series of data points indexed in time order.
• We will discover and explore data from the stock market, particularly some
technology stocks (Apple, Amazon, Google, and Microsoft). We will learn
how to use yfinance to get stock information, and visualize different aspects
of it using Seaborn and Matplotlib. We will also be predicting future stock
prices through a Long Short Term Memory (LSTM) method!
31. WE'LL BE ANSWERING THE FOLLOWING QUESTIONS
ALONG THE WAY
1.) What was the change in price of the stock over time
2.) What was the daily return of the stock on average
3.) What was the moving average of the various stocks
4.) What was the correlation between different stocks
5.) How much value do we put at risk by investing in a particular stock 6.) How
can we attempt to predict future stock behavior (Predicting the closing price
stock price of APPLE inc using LSTM)
32. GETTING THE DATA
• The first step is to get the data and load it to memory.
• We will get our stock data from the Yahoo Finance website.
• Yahoo Finance is a rich resource of financial market data and tools to find
compelling investments.
• To get the data from Yahoo Finance, we will be using yfinance library which
offers a threaded and Pythonic way to download market data from Yahoo.
33. WHAT WAS THE CHANGE IN PRICE OF THE STOCK
OVERTIME?
• In this section we'll go over how to handle requesting stock information with
pandas, and how to analyze basic attributes of a stock.
34.

37. DESCRIPTIVE STATISTICS ABOUT THE DATA
• .describe() generates descriptive statistics. Descriptive statistics include those that
summarize the central tendency, dispersion, and shape of a dataset’s distribution,
excluding NaN values.
• Analyzes both numeric and object series, as well as DataFrame column sets of mixed data
types. The output will vary depending on what is provided. Refer to the notes below for more
detail.
38. DESCRIPTIVE STATISTICS ABOUT THE DATA
We have only 255 records in one year because weekends are not included in the data
39. INFORMATION ABOUT THE DATA
• .info() method prints information about a DataFrame including the
index dtype and columns, non-null values, and memory usage.
40. CLOSING PRICE
• The closing price is the last price at which the stock is traded during the regular trading day.
A stock’s closing price is the standard benchmark used by investors to track its performance
over time.
42. VOLUME OF SALES
• Volume is the amount of an asset or security that changes hands over some period of time, often over
the course of a day. For instance, the stock trading volume would refer to the number of shares of
security traded between its daily open and close. Trading volume, and changes to volume over the
course of time, are important inputs for technical traders.
