The document talks about the overview behind the need and drive for NoSQL databases. It also mentions about some of the most popular NoSQL databases in the market.
A data warehouse is a relational database that is designed for query and analysis rather than for transaction processing. It usually contains historical data derived from transaction data, but it can include data from other sources. It separates analysis workload from transaction workload and enables an organization to consolidate data from several sources.
In addition to a relational database, a data warehouse environment includes an extraction, transportation, transformation, and loading (ETL) solution, an online analytical processing (OLAP) engine, client analysis tools, and other applications that manage the process of gathering data and delivering it to business users.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

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

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

1. CS 678 - Ensembles and Bayes 1
Semi-Supervised Learning
Can we improve the quality of our learning by combining
labeled and unlabeled data
Usually a lot more unlabeled data available than labeled
Assume a set L of labeled data and U of unlabeled data
(from the same distribution)
Focus on Semi-Supervised Classification though there are
many other variations
– Aiding clustering with some labeled data
– Regression
– Model selection with unlabeled data (COD)
Transduction vs Induction
2. How Semi-Supervised Works
Most approaches make strong model assumptions
(guesses). If wrong can make things worse.
Some commonly used assumptions:
– Clusters of data are from the same class
– Data can be represented as a mixture of parameterized distributions
– Decision boundaries should go through non-dense areas of the data
– Model should be as simple as possible (Occam)
CS 678 - Ensembles and Bayes 2
3. Unsupervised Learning of Domain
Features
PCA, SVD
NLDR – Non-Linear Dimensionality Reduction
Many Deep Learning Models
– Deep Belief Nets
– Sparse Auto-encoders
– Self-Taught Learning

5. Self-Training (Bootstrap)
Self-Training
– Train supervised model on labeled data L
– Test on unlabeled data U
– Add the most confidently classified members of U to L
– Repeat
Multi-Model
– Uses multiple models to label/move instances of U to L
– Co-Training
Train two models with different independent features sets
Add most confident instances from U of one model into L of the other (i.e.
they “teach” each other)
Repeat
– Multi-View Learning
Train multiple diverse models on L. Those instances in U which most
models agree on are placed in L.
CS 678 - Ensembles and Bayes 5
6. Generative Models
Generative – Assume data can be represented by some
mixture of parameterized models (e.g. Gaussian) and use
EM to learn parameters (ala Baum-Welch)
CS 678 - Ensembles and Bayes 6
7. Graph Models
Graph Models
– Neighbor nodes assumed to be similar with larger edge weights
– Force same class member in L to be close, while maintaining
smoothness with respect to the graph for U.
– Add in members of U as neighbors based on some similarity
– Iteratively label U (breadth first)
CS 678 - Ensembles and Bayes 7
8. TSVM
Transductive SVM (TSVM) or Semi-Supervised SVM
(S3VM)
Maximize margin of both L and U. Decision surface
placed in non-dense spaces
– Assumes classes are "well-separated"
– Can also try to simultaneously maintain class proportion on both
sides similar to labeled proportion
CS 678 - Ensembles and Bayes 8
9. Summary
Oracle Learning
Becoming a more critical area as more unlabeled data
becomes cheaply available
CS 678 - Ensembles and Bayes 9
10. Active Learning
Obtaining labeled data can be the most expensive part of a
machine learning task
Supervised, Unsupervised, and Semi-Supervised Learning
In Active Learning can query an oracle (e.g. a human
expert, test, etc.) to obtain the label for a specific input
In active learning we try to learn the most accurate model
while having to query the least amount of data for labels
