Logistic bifurcation diagram in detail

The image below is famous. I’ve seen it many times, but rarely with a detailed explanation. If you’ve ever seen this image but weren’t sure exactly what it means, this post is for you.

We are advertising three 3-year PhD scholarships in algorithms at
The University of Sydney, Australia.

The successful applicant will conduct research with Joachim Gudmundsson,
William Umboh, and André van Renssen in the Sydney Algorithms and
Computing Theory (SACT) group.

The specific topic will depend on the skills and interests of the student and
could include for example computational geometry, network design, routing,
trajectory analysis, approximation algorithms, and online algorithms.

The Full Scholarship will provide tuition fees and annual stipend
allowance for up to three years, subject to satisfactory academic performance.

The recipient may apply for an extension of up to 6 months.

For more details about the positions and on how to apply:
https://sydney.edu.au/scholarships/b/postgraduate-research-scholarship-in-algorithms.html

Application date: 27 February 2020 (Sydney time).

Please forward to anyone who might be interested.

If you have any questions, you are welcome to mail us directly

Mathematical Methods and Models in Machine Learning

The meeting takes place at the Department of Mathematics of the University of Bologna on 27 and 28 April 2020.

https://eventi.unibo.it/m4l2020

Aim of the meeting
The gap between the increasing performance of deep learning and its understanding is therefore a very relevant scientific theme that calls for a strong participation in research efforts from the fields of Mathematics and Mathematical Physics.

The purpose of the conference is to present recent results on mathematical methods and models related to machine learning and link researchers coming from different areas.


Registration
Registration is required by March 10 at 11am. It is possible to apply for a short talk

رویکردهای مختلفی جهت ترسیم میزان توسعه اقتصادی کشورها مورد استفاده قرار می­گیرند، اما از آنجایی که این رویکردها معمولاً مالی بوده و تحت تأثیر نوسانات اقتصادی داخلی و خارجی همچون تورم، رکود و ... قرار می­ گیرند. لذا قابلیت اتکاء در جهت تبیین و آزمون فرضیات و تئوری­ های اقتصادی را ندارند. با توجه به پیچیدگی ­هایی که در عرصه اقتصاد در حال رخ دادن هستند و نیز شناخت بهتر موقعیت فعلی کشورها، پرداختن به روش ­ها و ابزارهای کارآمدتر جهت تجزیه و تحلیل اقتصاد کشور از ضرورت ­های حال حاضر اقتصاد است. به همین دلیل الزام به روی آوردن به تفکر جدید اقتصادی است. در همین راستا رویکرد پیچیدگی اقتصادی، اقتصاد را نه به عنوان یک سیستم در تعادل، بلکه به عنوان سیستمی می­بیند که در حال حرکت بوده و به طور مداوم خود را از نو می ­سازد. در این راستا لازم دیده شد تا به برگزاری کنفرانسی ملی تحت عنوان علم، فناوری و پیچیدگی اقتصادی اقدام گردد، بلکه بتوان به ترویج این رویکرد و کاربردهای آن در حوزه های مختلف سیاست گذاری و تصمیم گیری نائل آییم.
