 Welcome to my channel. Today we are going to see how to prepare a presentation. I am Alfredo Canziani and you can find me on Twitter under AlfCNZ. Objectives, sensitization on presentation importance, we see why it matters, practical advices on preparation. I try to illustrate all the effective techniques that may be required. Typical scenario. You've completed a large and complex project. You're proud of quantity and quality. You need to present it. Objective, convince others about quality of job and results and your quality. Average student does not understand the presentation importance. Beliefs jobs quality is obvious. Does not perceive the difficulty of crafting a presentation. Consider it a formality, a burden. Craft it without commensurate effort. Does ignore the fundamental rules. Love or nature. If an awesome job is terribly presented, then no one understands it's awesome or the job is perceived as terrible. Ideal scenario. Plenty of time for presenting. Everyone's dying to listen to you. Everyone knows objectives and problems. Everyone's absolutely paying attention without interruption. Easy. Real scenario. You have roughly 20 minutes. Someone remember what you had to do. A few know the technicalities. Everyone's going through something in life. Not everyone can or wants to pay attention all the time. Very, very, very hard. General premises. What's the context? To whom shall I present? How long do I have? To whom shall I present? University lesson? University seminar? High school conference. Non-scientific talk. Large scientific conference. Or perhaps this is the fence. Newbie hypothesis. Infinite amount of time. Need to talk about everything that has been done. The audience has infinite intelligence and has infinite comprehension speed. A few reviews to the initial draft are sufficient. Correct hypothesis. I have K minutes. I need to practice. Many interesting things will definitely be skipped. If I prepare well, someone may understand something. Will be required very many iterations. And edit. Infinite comprehension speed. Total time. Five seconds to say. As you can see, we are the best performing solution. Next. Correct approach. Explain explicit what X and Y axes are. Command every chart. Point out the most significant part. State if better is above or below. If possible show ideal curve. Presentation organization. Initial part. Two questions to address. What is the problem? Why it is relevant? Common wrong approach. A mixture of what has been done. How it works. Well, this is the solution. Nope. How can anyone understand anything if no problem has been described at all? Problem is not the solution. Solution details are little important. No one understands them. You have too short time. You have an heterogenic audience. They are not the presentation objective. There are thesis and article for use for this purpose. Problem relevance. Very important. Everyone can understand it. Problem description. First part. It is the most critical and most important part. Who does not understand it? Turns off. You will not get them back. It is the only fully understandable part. If you are not able to explain the problem, how can you motivate a listener? Problem description. Part two. From one sentence up to two slides. Depends on problem nature and audience type. Do not spare effort. Rehears. Rehears. And rehearse again. Problem description. Part three. Concise. And separated from why it is relevant. Specific. Generic versus specific. Example Grazia. Part one. Text to image. Nope. Generative adversarial text to image synthesis. Yes. Generic versus specific. Example Grazia. Second part. Image in painting. Nope. Semantic image in painting with deep generative models. Yes. This solution. Part one. The details can be understood only by whom has already worked on the same problem. Often, no one understands them. Cannot be written approximately. Who is interested will make questions. The solution. Part two. It does not make sense to fill slides with formula, algorithm and diagrams. Tell the whole journey to get to the solution. It's hard enough to communicate the relevance. Not how it works, but why it is necessary. This is the fence. Need to identify the personal contribution. Which is often hard to grasp. Personal contribution. Things not to do. Waste time on project importance. Candidate work is under evaluation. Not the project or affiliations. Things to do. How it was before and how it was after. What you did and what others did. Practical suggestions. Presentation preparation. Estimate from two to three minutes per slide. Fundamental for assessing how many things can be told and convince oneself that many things won't be said. Give up to begin with. Do not rush describing everything. Carefully curate problem and relevance. A few interesting bits will have to be omitted. Never speed up or reduce the explanations in order to say more things. Please mind the time. Never exceed the allocated time. In the real world, time is the most valuable resource anyone has. Basic respect character towards colleagues and audience. Better finish slightly earlier than later. Never end up with 15 slides two minutes to the end. Never make many trials. Perform presenting trials allowed. Very annoying but indispensable. Estimate timings. Identify complex or dangerous points. Memorize the beginning. Learn by heart the first three to four minutes. Necessary to get going. If you freeze at the beginning because you're emotional you stay frozen. Last month I was on national television. I was petrified but after I started I just kept going and going. Never improvise. Decide in advance what to and not to say. Never add on the go. One may often want to add and clarify. Very dangerous. Turn a blind eye if needed. Questions will be asked. Do not talk of things you didn't plan to talk about. Where to look? Do not make eye contact. Easy to discourage oneself. He's sleeping. Am I saying boring things? Oh she's laughing. Am I telling stupid things? And so on. Look at the opposite wall. Do not expect nothing. Any feedback to consider? Questions? How to speak? Slowly. Without hurry. Loudly. Impossible. Following high speed speech. Concentrating on listening. Whisper. Many may included. Do not like seeing the speaker with his or her hands in his or her pockets. Practical suggestions. The slides. Better these or these. What is a slide? An aid for the presenter. And above all for the audience. Use for following a presentation. It is not the presentation. Density. It must be comprehensible at first sight. Not full of words. Not a presentation transcript. Although this is an exception. Writing style. Adopt a telegram style. Eliminate any unnecessary word. Follow this algorithm. Write a sentence. Remove every unnecessary word. Logic structure. Imply graphical structure. Clearly separate concepts with graphics. Massent require reading concentration. Who concentrates reading? Won't concentrate listening. Suggest a style. Pallet points with one concept per point. One or two hierarchical levels. Reasonable use of bold, italic and a few colors. Advanced style. Avoid text altogether. Use drawings and animations. Font. At least 20 points. 24 is better. 28 is perfect. Printed fonts are bad for screen font. Times New Roman is not okay. Palatino is also not okay. Calibri, Tahorma, Aerial, Helvetica are all good choices. Colors. Better. Black background and white characters. Or white background and black characters. It's so bright. Oh god. Better than weird combinations like these two. Special effects. Remove special effects. Fading is all you need. Technical presentation is not an advertisement. It's not easy. Rehearsal, rehearse, rehearse. Summarizing. Independently from your future career, having technical qualities is not enough. It's fundamental that they can be communicated to others. Fundamental. To know how to present your own work. Spend time and effort in the preparation. Last slide. Will be shown for the longest amount of time. Do not waste it to thank the audience. Use it for something meaningful. Summary of achievements. Future work. Or list of published work.
