مرزا محمد عسکری

مرزا محمد عسکری
افسوس ہے کہ گزشتہ مہینہ اردو زبان کی صف میں دوممتاز جگہیں خالی ہوگئیں، اور مرزا محمد عسکری اور مولوی مہیش پرشاد ہم سے جدا ہوگئے، مرزا صاحب مرحوم قدیم مشرقی تہذیب کا نمونہ، لکھنو کی پرانی بزم ادب کی یادگار، اردو زبان و ادب کے صاحب ذوق و نکتہ سنج ادیب اور متعدد کتابوں کے مصنف و مترجم تھے، ان کی سب سے بڑی علمی یادگار بابو سکسینہ کی تاریخ ادبیات اردو کا ترجمہ ہے، اس میں انھوں نے اتنے اضافے کئے ہیں، اور اس کو اس طرح اردو کے قالب میں ڈھالا ہے کہ اس کی حیثیت تصنیف کی ہوگئی ہے، جس طرح جناب صفی اور آرزو پر لکھنو کی قدیم بزم شاعری کا خاتمہ ہوگیا، اسی طرح مرزا صاحب کی وفات سے اس دور کی بزم ادب کی آخری یادگار مٹ گئی اب وہ تہذیب ہی ختم ہوگئی، وہ سانچہ ہی بدل گیا جس میں تہذیب و شائستگی اور ذوقِ ادب کے یہ نمونے ڈھلتے تھے، اس لئے آئندہ ان کے پیدا ہونے کی امید نہیں اور ان کی جو جگہ بھی ہوگی، وہ خالی ہی رہے گی۔ (شاہ معین الدین ندوی، اکتوبر ۱۹۵۱ء)

خواتین کی دینی تعلیم: روایت، مسائل اور عصری تحدیات

The role of madaris in spreading Islamic knowledge is an admitted fact. This blessed effort started from Dar-e-Arqam (Makkah) and Suffa (Madinah) as very first Islamic institutions. The role of madaris in producing scholars has been vital. In Islamic world, some universities and madaris got great repute. These institutions have splendid history and valuable tradition of teaching Quran and Sunnah. Along with this, madaris went through reforms time by time. There is a widespread criticism on these institutions. This is a result of sincere concern but most of the times, of mere propaganda and stereotypes. Women madaris certainly are in need of radical reforms to meet the challenges of modernity and globalization. Changing role of women requires a paradigm shift in curricula, teaching methods and training methodology. This article “Balancing one’s rights and responsibilities” is an effort to identify some of the contemporary needs of the Muslim women’s education and curricula. This is the way Muslim women can attain their dynamic role in society by adopting reforms to meet the challenges of the day.

Development of Feature Selection Algorithms for High-Dimensional Binary Data

There has been a growing interest in representing real-life applications with data sets having binary-valued features. These data sets due to the advancements in computer and data management systems consist of tens or hundreds of thousands of features. In this dissertation, we investigate two problems in machine learning which have been relatively less studied for high-dimensional binary data. The first problem is to select a subset of features useful for supervised learning applications from the entire feature set and is known as the feature selection (FS) problem. The second problem is to compare two orderings of features induced by feature ranking (FR) algorithms and to determine which one is better. For the feature selection problem, we have proposed a new feature ranking measure termed as the diff-criterion. Its distinct attribute is that it estimates the usefulness of binary features by using their probability distributions. The diff-criterion has been evaluated against two well-known FS algorithms with four widely used clas- sifiers on six binary data sets on which it has achieved up to about 99% reduction in the feature set size. To further improve the performance, we have suggested a two-stage FS algorithm. The novelty of our two-stage algorithm is that the first stage provides the second stage with a reduced subset without losing valuable in- formation about the class. Two-stage feature selection used with the diff-criterion not only significantly improves the classification accuracy but also exhibits up to about 99% reduction in the feature set size. We have also compared our proposed FS algorithms against the winning entries of the “Agnostic Learning versus Prior Knowledge” challenge. The algorithms have shown results better or comparable to the winners of the challenge. For the problem of ranking features using FR algorithms, different FR algorithms estimate the importance of features with respect to the class variable differently thus generating different orderings. To determine which ordering is better, we propose a new evaluation method termed as feature ranking evaluation strategy (FRES). It uses the individual predictive power of features for estimating howAbstract correct is an ordering of features. We found that compared to Relief and mu- tual information algorithms our proposed diff-criterion generates the most correct orderings of binary features.
